For the purposes of this paragraph, the term19 "business" shall mean a sole proprietor, partnership, or limited liability company. For20 the purposes of this paragraph for determining the number of single family homes21 leased for a term of less than thirty consecutive days, in whole or in part, subject to sales22 tax under subdivision (6) of subsection 1 of section 144.020 owned by an individual or23 business, all single family homes that are such properties owned by the individual or24 business, or owned by any business entity in which such individual or business holds any25 ownership, membership, or beneficial interest, direct or indirect, shall be counted. The26 provisions of this paragraph shall not be construed to authorize the classification of any27 real property owned by a corporation as residential property;2829 Residential property shall not include other similar facilities used primarily for transient30 housing. For the purposes of this section, "transient housing" means all rooms available for31 rent or lease for which the receipts from the rent or lease of such rooms are subject to state32 sales tax pursuant to subdivision (6) of subsection 1 of section 144.020; the leasing of a33 single family home, in whole or in part, for a term of less than thirty consecutive days34 does not, in itself, constitute "transient housing";35(2) "Agricultural and horticultural property", all real property used for agricultural36 purposes and devoted primarily to the raising and harvesting of crops; to the feeding,37 breeding and management of livestock which shall include breeding, showing, and boarding38 of horses; to dairying, or to any other combination thereof; and buildings and structures39 customarily associated with farming, agricultural, and horticultural uses. Agricultural and40 horticultural property shall also include land devoted to and qualifying for payments or other41 compensation under a soil conservation or agricultural assistance program under an42 agreement with an agency of the federal government. Agricultural and horticultural property43 shall further include any reliever airport. Real property classified as forest croplands shall not44 be agricultural or horticultural property so long as it is classified as forest croplands and shall45 be taxed in accordance with the laws enacted to implement Section 7 of Article X of the46 Missouri Constitution. Agricultural and horticultural property shall also include any sawmill47 or planing mill defined in the U.S. Department of Labor's Standard Industrial ClassificationHCS SS SCS SBs 1066 & 1088 548 (SIC) Manual under Industry Group 242 with the SIC number 2421. Agricultural and49 horticultural property shall also include urban and community gardens. For the purposes of50 this section, "urban and community gardens" shall include real property cultivated by51 residents of a neighborhood or community for the purposes of providing agricultural52 products, as defined in section 262.900, for the use of residents of the neighborhood or53 community, and shall not include a garden intended for individual or personal use;54(3) "Utility, industrial, commercial, railroad and other real property", all real property55 used directly or indirectly for any commercial, mining, industrial, manufacturing, trade,56 professional, business, or similar purpose, including all property centrally assessed by the57 state tax commission but shall not include floating docks, portions of which are separately58 owned and the remainder of which is designated for common ownership and in which no one59 person or business entity owns more than five individual units.

Pursuant to Article X of the state Constitution, any taxing district may adjust its64 operating levy to recoup any loss of property tax revenue, except revenues from the surtax65 imposed pursuant to Article X, Subsection 2 of Section 6 of the Constitution, as the result of66 changing the classification of structures intended to be used for residential living by human67 occupants which contain five or more dwelling units if such adjustment of the levy does not68 exceed the highest tax rate in effect subsequent to the 1980 tax year. For purposes of this69 section, loss in revenue shall include the difference between the revenue that would have been70 collected on such property under its classification prior to enactment of this section and the71 amount to be collected under its classification under this section. The county assessor of each72 county or city not within a county shall provide information to each taxing district within its73 boundaries regarding the difference in assessed valuation of such property as the result of74 such change in classification.753. All reclassification of property as the result of changing the classification of76 structures intended to be used for residential living by human occupants which contain five or77 more dwelling units shall apply to assessments made after December 31, 1994.784. Where real property is used or held for use for more than one purpose and such79 uses result in different classifications, the county assessor shall allocate to each classification80 the percentage of the true value in money of the property devoted to each use; except that,81 where agricultural and horticultural property, as defined in this section, also contains a82 dwelling unit or units, the farm dwelling, appurtenant residential-related structures and up to83 five acres immediately surrounding such farm dwelling shall be residential property, as84 defined in this section, provided that the portion of property used or held for use as an urbanHCS SS SCS SBs 1066 & 1088 685 and community garden shall not be residential property. This subsection shall not apply to86 any reliever airport.875. All real property which is vacant, unused, or held for future use; which is used for a88 private club, a not-for-profit or other nonexempt lodge, club, business, trade, service89 organization, or similar entity; or for which a determination as to its classification cannot be90 made under the definitions set out in subsection 1 of this section, shall be classified according91 to its immediate most suitable economic use, which use shall be determined after92 consideration of:93(1) Immediate prior use, if any, of such property;94(2) Location of such property;95(3) Zoning classification of such property; except that, such zoning classification96 shall not be considered conclusive if, upon consideration of all factors, it is determined that97 such zoning classification does not reflect the immediate most suitable economic use of the98 property;99(4) Other legal restrictions on the use of such property;100(5) Availability of water, electricity, gas, sewers, street lighting, and other public101 services for such property;102(6) Size of such property;103(7) Access of such property to public thoroughfares; and104(8) Any other factors relevant to a determination of the immediate most suitable105 economic use of such property.1066. All lands classified as forest croplands shall not, for taxation purposes, be107 classified as subclass (1), subclass (2), or subclass (3) real property, as such classes are108 prescribed in Section 4(b) of Article X of the Missouri Constitution and defined in this109 section, but shall be taxed in accordance with the laws enacted to implement Section 7 of110 Article X of the Missouri Constitution.137.039. 1. As used in this section, "additional tax abatement revenues" means2 revenues derived from higher tax levies on real property inside a political subdivision3 that has adopted any tax abatement or similar economic incentive authorized under4 general law but outside an area subject to tax abatement within the political subdivision.52. Beginning on January first of the calendar year immediately following the6 effective date of this section, each political subdivision that adopts or has adopted any7 tax abatement or similar economic incentive authorized under state law shall decrease8 the levy of real property tax rates levied under state law to reduce the amount of tax9 revenues such political subdivision received from additional tax abatement revenues.137.073. 1. As used in this section, the following terms mean:HCS SS SCS SBs 1066 & 1088 72(1) "General reassessment", changes in value, entered in the assessor's books, of a3 substantial portion of the parcels of real property within a county resulting wholly or partly4 from reappraisal of value or other actions of the assessor or county equalization body or5 ordered by the state tax commission or any court;6(2) "Tax rate", "rate", or "rate of levy", singular or plural, includes the tax rate for7 each purpose of taxation of property a taxing authority is authorized to levy without a vote8 and any tax rate authorized by election, including bond interest and sinking fund;9(3) "Tax rate ceiling", a tax rate as revised by the taxing authority to comply with the10 provisions of this section or when a court has determined the tax rate; except that, other11 provisions of law to the contrary notwithstanding, a school district may levy the operating12 levy for school purposes required for the current year pursuant to subsection 2 of section13 163.021, less all adjustments required pursuant to Article X, Section 22 of the Missouri14 Constitution, if such tax rate does not exceed the highest tax rate in effect subsequent to the15 1980 tax year. This is the maximum tax rate that may be levied, unless a higher tax rate16 ceiling is approved by voters of the political subdivision as provided in this section;17(4) "Tax revenue", when referring to the previous year, means the actual receipts from18 ad valorem levies on all classes of property, including state-assessed property, in the19 immediately preceding fiscal year of the political subdivision, plus an allowance for taxes20 billed but not collected in the fiscal year and plus an additional allowance for the revenue21 which would have been collected from property which was annexed by such political22 subdivision but which was not previously used in determining tax revenue pursuant to this23 section. The term "tax revenue" shall not include any receipts from ad valorem levies on any24 property of a railroad corporation or a public utility, as these terms are defined in section25 386.020, which were assessed by the assessor of a county or city in the previous year but are26 assessed by the state tax commission in the current year. All school districts and those27 counties levying sales taxes pursuant to chapter 67 shall include in the calculation of tax28 revenue an amount equivalent to that by which they reduced property tax levies as a result of29 sales tax pursuant to section 67.505 and section 164.013 [or as excess home dock city or30 county fees as provided in subsection 4 of section 313.820] in the immediately preceding31 fiscal year but not including any amount calculated to adjust for prior years. For purposes of32 political subdivisions which were authorized to levy a tax in the prior year but which did not33 levy such tax or levied a reduced rate, the term "tax revenue", as used in relation to the34 revision of tax levies mandated by law, shall mean the revenues equal to the amount that35 would have been available if the voluntary rate reduction had not been made.362. (1) Whenever changes in assessed valuation are entered in the assessor's books for37 any personal property, in the aggregate, or for any subclass of real property as such subclasses38 are established in Section 4(b) of Article X of the Missouri Constitution and defined inHCS SS SCS SBs 1066 & 1088 839 section 137.016, the county clerk in all counties and the assessor of St. Louis City shall notify40 each political subdivision wholly or partially within the county or St. Louis City of the change41 in valuation of each subclass of real property, individually, and personal property, in the42 aggregate, exclusive of new construction and improvements. All political subdivisions shall43 immediately revise the applicable rates of levy for each purpose for each subclass of real44 property, individually, and personal property, in the aggregate, for which taxes are levied to45 the extent necessary to produce from all taxable property, exclusive of new construction and46 improvements, substantially the same amount of tax revenue as was produced in the previous47 year for each subclass of real property, individually, and personal property, in the aggregate,48 except that the rate shall not exceed the greater of the most recent voter-approved rate or the49 most recent voter-approved rate as adjusted under subdivision (2) of subsection 5 of this50 section.51(2) Any political subdivision that has received approval from voters for a tax increase52 after August 27, 2008, may levy a rate to collect substantially the same amount of tax revenue53 as the amount of revenue that would have been derived by applying the voter-approved54 increased tax rate ceiling to the total assessed valuation of the political subdivision as most55 recently certified by the city or county clerk on or before the date of the election in which56 such increase is approved, increased by the percentage increase in the consumer price index,57 as provided by law, except that the [rate] rates of levy for each subclass of real property,58 individually, and personal property, in the aggregate, shall not exceed the greater of the59 most recent voter-approved rate or the most recent voter-approved rate as adjusted under60 subdivision (2) of subsection 5 of this section. Such tax revenue shall not include any receipts61 from ad valorem levies on any real property which was assessed by the assessor of a county62 or city in such previous year but is assessed by the assessor of a county or city in the current63 year in a different subclass of real property.64(3) Where the taxing authority is a school district for the purposes of revising the65 applicable rates of levy for each subclass of real property, the tax revenues from state-66 assessed railroad and utility property shall be apportioned and attributed to each subclass of67 real property based on the percentage of the total assessed valuation of the county that each68 subclass of real property represents in the current [taxable] tax year.69(4) As provided in Section 22 of Article X of the constitution, a political subdivision70 may also revise each levy to allow for inflationary assessment growth occurring within the71 political subdivision. The inflationary growth factor for any such subclass of real property or72 personal property shall be limited to the actual assessment growth in such subclass or class,73 exclusive of new construction and improvements, and exclusive of the assessed value on any74 real property which was assessed by the assessor of a county or city in the current year in a75 different subclass of real property, but not to exceed the consumer price index or five percent,HCS SS SCS SBs 1066 & 1088 976 whichever is lower. [Should the tax revenue of a political subdivision from the various tax77 rates determined in this subsection be different than the tax revenue that would have been78 determined from a single tax rate as calculated pursuant to the method of calculation in this79 subsection prior to January 1, 2003, then the political subdivision shall revise the tax rates of80 those subclasses of real property, individually, and/or personal property, in the aggregate, in81 which there is a tax rate reduction, pursuant to the provisions of this subsection. Such82 revision shall yield an amount equal to such difference and shall be apportioned among such83 subclasses of real property, individually, and/or personal property, in the aggregate, based on84 the relative assessed valuation of the class or subclasses of property experiencing a tax rate85 reduction. Such revision in the tax rates of each class or subclass shall be made by computing86 the percentage of current year adjusted assessed valuation of each class or subclass with a tax87 rate reduction to the total current year adjusted assessed valuation of the class or subclasses88 with a tax rate reduction, multiplying the resulting percentages by the revenue difference89 between the single rate calculation and the calculations pursuant to this subsection and90 dividing by the respective adjusted current year assessed valuation of each class or subclass to91 determine the adjustment to the rate to be levied upon each class or subclass of property. The92 adjustment computed herein shall be multiplied by one hundred, rounded to four decimals in93 the manner provided in this subsection, and added to the initial rate computed for each class94 or subclass of property. For school districts that levy separate tax rates on each subclass of95 real property and personal property in the aggregate, if voters approved a ballot before96 January 1, 2011, that presented separate stated tax rates to be applied to the different97 subclasses of real property and personal property in the aggregate, or increases the separate98 rates that may be levied on the different subclasses of real property and personal property in99 the aggregate by different amounts, the tax rate that shall be used for the single tax rate100 calculation shall be a blended rate, calculated in the manner provided under subdivision (1) of101 subsection 6 of this section.]102(5) Notwithstanding any provision of this subsection to the contrary, no revision to103 the rate of levy for personal property shall cause such levy to increase over the levy for104 personal property from the prior year.1053. (1) Where the taxing authority is a school district, it shall be required to revise the106 rates of levy to the extent necessary to produce from all taxable property, including state-107 assessed railroad and utility property, which shall be separately estimated in addition to other108 data required in complying with section 164.011, substantially the amount of tax revenue109 permitted in this section. In the year following tax rate reduction, the tax rate ceiling may be110 adjusted to offset such district's reduction in the apportionment of state school moneys due to111 its reduced tax rate. However, in the event any school district, in calculating a tax rate ceiling112 pursuant to this section, requiring the estimating of effects of state-assessed railroad andHCS SS SCS SBs 1066 & 1088 10113 utility valuation or loss of state aid, discovers that the estimates used result in receipt of114 excess revenues, which would have required a lower rate if the actual information had been115 known, the school district shall reduce the tax rate ceiling in the following year to compensate116 for the excess receipts, and the recalculated rate shall become the tax rate ceiling for purposes117 of this section.118(2) For any political subdivision which experiences a reduction in the amount of119 assessed valuation relating to a prior year, due to decisions of the state tax commission or a120 court pursuant to sections 138.430 to 138.433, or due to clerical errors or corrections in the121 calculation or recordation of any assessed valuation:122(a) Such political subdivision may revise the tax rate ceiling for each purpose it levies123 taxes to compensate for the reduction in assessed value occurring after the political124 subdivision calculated the tax rate ceiling for the particular subclass of real property or for125 personal property, in the aggregate, in a prior year. Such revision by the political subdivision126 shall be made at the time of the next calculation of the tax rate for the particular subclass of127 real property or for personal property, in the aggregate, after the reduction in assessed128 valuation has been determined and shall be calculated in a manner that results in the revised129 tax rate ceiling being the same as it would have been had the corrected or finalized assessment130 been available at the time of the prior calculation;131(b) In addition, for up to three years following the determination of the reduction in132 assessed valuation as a result of circumstances defined in this subdivision, such political133 subdivision may levy a tax rate for each purpose it levies taxes above the revised tax rate134 ceiling provided in paragraph (a) of this subdivision to recoup any revenues it was entitled to135 receive had the corrected or finalized assessment been available at the time of the prior136 calculation.1374. (1) In order to implement the provisions of this section and Section 22 of Article X138 of the Constitution of Missouri, the term improvements shall apply to both real and personal139 property. In order to determine the value of new construction and improvements, each county140 assessor shall maintain a record of real property valuations in such a manner as to identify141 each year the increase in valuation for each political subdivision in the county as a result of142 new construction and improvements. The value of new construction and improvements shall143 include the additional assessed value of all improvements or additions to real property which144 were begun after and were not part of the prior year's assessment, except that the additional145 assessed value of all improvements or additions to real property which had been totally or146 partially exempt from ad valorem taxes pursuant to sections 99.800 to 99.865, sections147 135.200 to 135.255, and section 353.110 shall be included in the value of new construction148 and improvements when the property becomes totally or partially subject to assessment and149 payment of all ad valorem taxes. The aggregate increase in valuation of personal property forHCS SS SCS SBs 1066 & 1088 11150 the current year over that of the previous year is the equivalent of the new construction and151 improvements factor for personal property. [Notwithstanding any opt-out implemented152 pursuant to subsection 14 of section 137.115,] The assessor shall certify the amount of new153 construction and improvements and the amount of assessed value on any real property which154 was assessed by the assessor of a county or city in such previous year but is assessed by the155 assessor of a county or city in the current year in a different subclass of real property156 separately for each of the three subclasses of real property for each political subdivision to the157 county clerk in order that political subdivisions shall have this information for the purpose of158 calculating tax rates pursuant to this section and Section 22, Article X, Constitution of159 Missouri. In addition, the state tax commission shall certify each year to each county clerk160 the increase in the general price level as measured by the Consumer Price Index for All Urban161 Consumers for the United States, or its successor publications, as defined and officially162 reported by the United States Department of Labor, or its successor agency. The state tax163 commission shall certify the increase in such index on the latest twelve-month basis available164 on February first of each year over the immediately preceding prior twelve-month period in165 order that political subdivisions shall have this information available in setting their tax rates166 according to law and Section 22 of Article X of the Constitution of Missouri. For purposes of167 implementing the provisions of this section and Section 22 of Article X of the Missouri168 Constitution, the term "property" means all taxable property, including state-assessed169 property.170(2) Each political subdivision required to revise rates of levy pursuant to this section171 or Section 22 of Article X of the Constitution of Missouri shall calculate each tax rate it is172 authorized to levy and, in establishing each tax rate, shall consider each provision for tax rate173 revision provided in this section and Section 22 of Article X of the Constitution of Missouri,174 separately and without regard to annual tax rate reductions provided in section 67.505 and175 section 164.013. Each political subdivision shall set each tax rate it is authorized to levy176 using the calculation that produces the lowest tax rate ceiling. It is further the intent of the177 general assembly, pursuant to the authority of Section 10(c) of Article X of the Constitution178 of Missouri, that the provisions of such section be applicable to tax rate revisions mandated179 pursuant to Section 22 of Article X of the Constitution of Missouri as to reestablishing tax180 rates as revised in subsequent years, enforcement provisions, and other provisions not in181 conflict with Section 22 of Article X of the Constitution of Missouri. Annual tax rate182 reductions provided in section 67.505 and section 164.013 shall be applied to the tax rate as183 established pursuant to this section and Section 22 of Article X of the Constitution of184 Missouri, unless otherwise provided by law.1855. (1) In all political subdivisions, the tax rate ceiling established pursuant to this186 section shall not be increased unless approved by a vote of the people. Approval of the higherHCS SS SCS SBs 1066 & 1088 12187 tax rate shall be by at least a majority of votes cast. When a proposed higher tax rate requires188 approval by more than a simple majority pursuant to any provision of law or the constitution,189 the tax rate increase must receive approval by at least the majority required.190(2) When voters approve an increase in the tax rate, the amount of the increase shall191 be added to the tax rate ceiling as calculated pursuant to this section to the extent the total rate192 does not exceed any maximum rate prescribed by law. If a ballot question presents a stated193 tax rate for approval rather than describing the amount of increase in the question, the stated194 tax rate approved shall be adjusted as provided in this section and, so adjusted, shall be the195 current tax rate ceiling. The increased tax rate ceiling as approved shall be adjusted such that,196 when applied to the current total assessed valuation of the political subdivision, excluding197 new construction and improvements since the date of the election approving such increase,198 the revenue derived from the adjusted tax rate ceiling is equal to the sum of: the amount of199 revenue which would have been derived by applying the voter-approved increased tax rate200 ceiling to total assessed valuation of the political subdivision, as most recently certified by the201 city or county clerk on or before the date of the election in which such increase is approved,202 increased by the percentage increase in the consumer price index, as provided by law. Such203 adjusted tax rate ceiling may be applied to the total assessed valuation of the political204 subdivision at the setting of the next tax rate. If a ballot question presents a phased-in tax rate205 increase, upon voter approval, each tax rate increase shall be adjusted in the manner206 prescribed in this section to yield the sum of: the amount of revenue that would be derived by207 applying such voter-approved increased rate to the total assessed valuation, as most recently208 certified by the city or county clerk on or before the date of the election in which such209 increase was approved, increased by the percentage increase in the consumer price index, as210 provided by law, from the date of the election to the time of such increase and, so adjusted,211 shall be the current tax rate ceiling.212(3) The provisions of subdivision (2) of this subsection notwithstanding, if prior213 to the expiration of a temporary levy increase voters approve a subsequent levy214 increase, the new tax rate ceiling shall remain in effect only until such time as the215 temporary levy expires under the terms originally approved by a vote of the people, at216 which time the tax rate ceiling shall be decreased by the amount of the temporary levy217 increase. If prior to the expiration of a temporary levy increase voters of a political218 subdivision are asked to approve an additional, permanent increase to the political219 subdivision's tax rate ceiling, voters shall be submitted ballot language that clearly220 indicates that if the permanent levy increase is approved, the temporary levy shall be221 made permanent.222(4) The governing body of any political subdivision may levy a tax rate lower than its223 tax rate ceiling and may, in a nonreassessment year, increase that lowered tax rate to a levelHCS SS SCS SBs 1066 & 1088 13224 not exceeding the tax rate ceiling without voter approval in the manner provided under225 subdivision [(4)] (5) of this subsection. Nothing in this section shall be construed as226 prohibiting a political subdivision from voluntarily levying a tax rate lower than that which is227 required under the provisions of this section or from seeking voter approval of a reduction to228 such political subdivision's tax rate ceiling.229[(4)] (5) In a year of general reassessment, a governing body whose tax rate is lower230 than its tax rate ceiling shall revise its tax rate pursuant to the provisions of subsection 4 of231 this section as if its tax rate was at the tax rate ceiling. In a year following general232 reassessment, if such governing body intends to increase its tax rate, the governing body shall233 conduct a public hearing, and in a public meeting it shall adopt an ordinance, resolution, or234 policy statement justifying its action prior to setting and certifying its tax rate. The provisions235 of this subdivision shall not apply to any political subdivision which levies a tax rate lower236 than its tax rate ceiling solely due to a reduction required by law resulting from sales tax237 collections. The provisions of this subdivision shall not apply to any political subdivision238 which has received voter approval for an increase to its tax rate ceiling subsequent to setting239 its most recent tax rate.240(6) (a) As used in this subdivision, the following terms mean:241a. "Current tax rate ceiling", the tax rate ceiling in effect before the voters242 approve a higher tax rate;243b. "Increased tax rate ceiling", the new tax rate ceiling in effect after the voters244 approve a higher tax rate.245(b) Notwithstanding any other provision of law to the contrary, when the246 required majority of voters in a political subdivision passes an increase in the political247 subdivision's tax rate, the political subdivision shall use the current tax rate ceiling and248 the increase approved by the voters in establishing the rates of levy for the tax year249 immediately following the election.250(c) If the assessed valuation of real property in such political subdivision is251 reduced in such tax year immediately following the election, such political subdivision252 may raise its rates of levy so that the revenue received from its local real property tax253 rates equals the amount the political subdivision would have received from the increased254 rates of levy had there been no reduction in the assessed valuation of real property in the255 political subdivision.256(d) Using the increased tax rate ceiling shall be revenue neutral as required in257 Article X, Section 22 of the Constitution of Missouri.2586. (1) For the purposes of calculating state aid for public schools pursuant to section259 163.031, each taxing authority which is a school district shall determine its proposed tax rate260 as a blended rate of the classes or subclasses of property. Such blended rate shall beHCS SS SCS SBs 1066 & 1088 14261 calculated by first determining the total tax revenue of the property within the jurisdiction of262 the taxing authority, which amount shall be equal to the sum of the products of multiplying263 the assessed valuation of each class and subclass of property by the corresponding tax rate for264 such class or subclass, then dividing the total tax revenue by the total assessed valuation of265 the same jurisdiction, and then multiplying the resulting quotient by a factor of one hundred.266 Where the taxing authority is a school district, such blended rate shall also be used by such267 school district for calculating revenue from state-assessed railroad and utility property as268 defined in chapter 151 and for apportioning the tax rate by purpose.269(2) Each taxing authority proposing to levy a tax rate in any year shall notify the clerk270 of the county commission in the county or counties where the tax rate applies of its tax rate271 ceiling and its proposed tax rate. Each taxing authority shall express its proposed tax rate in a272 fraction equal to the nearest one-tenth of a cent, unless its proposed tax rate is in excess of one273 dollar, then one/one-hundredth of a cent. If a taxing authority shall round to one/one-274 hundredth of a cent, it shall round up a fraction greater than or equal to five/one-thousandth of275 one cent to the next higher one/one-hundredth of a cent; if a taxing authority shall round to276 one-tenth of a cent, it shall round up a fraction greater than or equal to five/one-hundredths of277 a cent to the next higher one-tenth of a cent. Any taxing authority levying a property tax rate278 shall provide data, in such form as shall be prescribed by the state auditor by rule,279 substantiating such tax rate complies with Missouri law. All forms for the calculation of rates280 pursuant to this section shall be promulgated as a rule and shall not be incorporated by281 reference. The state auditor shall promulgate rules for any and all forms for the calculation of282 rates pursuant to this section which do not currently exist in rule form or that have been283 incorporated by reference. In addition, each taxing authority proposing to levy a tax rate for284 debt service shall provide data, in such form as shall be prescribed by the state auditor by rule,285 substantiating the tax rate for debt service complies with Missouri law. A tax rate proposed286 for annual debt service requirements will be prima facie valid if, after making the payment for287 which the tax was levied, bonds remain outstanding and the debt fund reserves do not exceed288 the following year's payments. The county clerk shall keep on file and available for public289 inspection all such information for a period of three years. The clerk shall, within three days290 of receipt, forward a copy of the notice of a taxing authority's tax rate ceiling and proposed291 tax rate and any substantiating data to the state auditor. The state auditor shall, within fifteen292 days of the date of receipt, examine such information and return to the county clerk his or her293 findings as to compliance of the tax rate ceiling with this section and as to compliance of any294 proposed tax rate for debt service with Missouri law. If the state auditor believes that a taxing295 authority's proposed tax rate does not comply with Missouri law, then the state auditor's296 findings shall include a recalculated tax rate, and the state auditor may request a taxing297 authority to submit documentation supporting such taxing authority's proposed tax rate. TheHCS SS SCS SBs 1066 & 1088 15298 county clerk shall immediately forward a copy of the auditor's findings to the taxing authority299 and shall file a copy of the findings with the information received from the taxing authority.300 The taxing authority shall have fifteen days from the date of receipt from the county clerk of301 the state auditor's findings and any request for supporting documentation to accept or reject in302 writing the rate change certified by the state auditor and to submit all requested information to303 the state auditor. A copy of the taxing authority's acceptance or rejection and any information304 submitted to the state auditor shall also be mailed to the county clerk. If a taxing authority305 rejects a rate change certified by the state auditor and the state auditor does not receive306 supporting information which justifies the taxing authority's original or any subsequent307 proposed tax rate, then the state auditor shall refer the perceived violations of such taxing308 authority to the attorney general's office and the attorney general is authorized to obtain309 injunctive relief to prevent the taxing authority from levying a violative tax rate.310(3) In the event that the taxing authority incorrectly completes the forms created and311 promulgated under subdivision (2) of this subsection, or makes a clerical error, the taxing312 authority may submit amended forms with an explanation for the needed changes. If such313 amended forms are filed under regulations prescribed by the state auditor, the state auditor314 shall take into consideration such amended forms for the purposes of this subsection.3157. No tax rate shall be extended on the tax rolls by the county clerk unless the political316 subdivision has complied with the foregoing provisions of this section.3178. Whenever a taxpayer has cause to believe that a taxing authority has not complied318 with the provisions of this section, the taxpayer may make a formal complaint with the319 prosecuting attorney of the county. Where the prosecuting attorney fails to bring an action320 within ten days of the filing of the complaint, the taxpayer may bring a civil action pursuant to321 this section and institute an action as representative of a class of all taxpayers within a taxing322 authority if the class is so numerous that joinder of all members is impracticable, if there are323 questions of law or fact common to the class, if the claims or defenses of the representative324 parties are typical of the claims or defenses of the class, and if the representative parties will325 fairly and adequately protect the interests of the class. In any class action maintained326 pursuant to this section, the court may direct to the members of the class a notice to be327 published at least once each week for four consecutive weeks in a newspaper of general328 circulation published in the county where the civil action is commenced and in other counties329 within the jurisdiction of a taxing authority. The notice shall advise each member that the330 court will exclude him or her from the class if he or she so requests by a specified date, that331 the judgment, whether favorable or not, will include all members who do not request332 exclusion, and that any member who does not request exclusion may, if he or she desires,333 enter an appearance. In any class action brought pursuant to this section, the court, in334 addition to the relief requested, shall assess against the taxing authority found to be inHCS SS SCS SBs 1066 & 1088 16335 violation of this section the reasonable costs of bringing the action, including reasonable336 attorney's fees, provided no attorney's fees shall be awarded any attorney or association of337 attorneys who receive public funds from any source for their services. Any action brought338 pursuant to this section shall be set for hearing as soon as practicable after the cause is at339 issue.3409. If in any action, including a class action, the court issues an order requiring a taxing341 authority to revise the tax rates as provided in this section or enjoins a taxing authority from342 the collection of a tax because of its failure to revise the rate of levy as provided in this343 section, any taxpayer paying his or her taxes when an improper rate is applied has erroneously344 paid his or her taxes in part, whether or not the taxes are paid under protest as provided in345 section 139.031 or otherwise contested. The part of the taxes paid erroneously is the346 difference in the amount produced by the original levy and the amount produced by the347 revised levy. The township or county collector of taxes or the collector of taxes in any city348 shall refund the amount of the tax erroneously paid. The taxing authority refusing to revise349 the rate of levy as provided in this section shall make available to the collector all funds350 necessary to make refunds pursuant to this subsection. No taxpayer shall receive any interest351 on any money erroneously paid by him or her pursuant to this subsection. Effective in the352 1994 tax year, nothing in this section shall be construed to require a taxing authority to refund353 any tax erroneously paid prior to or during the third tax year preceding the current tax year.35410. Any rule or portion of a rule, as that term is defined in section 536.010, that is355 created under the authority delegated in this section shall become effective only if it complies356 with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028.357 This section and chapter 536 are nonseverable and if any of the powers vested with the358 general assembly pursuant to chapter 536 to review, to delay the effective date, or to359 disapprove and annul a rule are subsequently held unconstitutional, then the grant of360 rulemaking authority and any rule proposed or adopted after August 28, 2004, shall be invalid361 and void.137.079. Prior to setting its [rate or] rates as required by section 137.073, each taxing2 authority shall exclude from its total assessed valuation seventy-two percent of the total3 amount of assessed value of business personal property that is the subject of an appeal at the4 state tax commission or in a court of competent jurisdiction in this state. This exclusion shall5 only apply to the portion of the assessed value of business personal property that is disputed6 in the appeal, and shall not exclude any portion of the same property that is not disputed. [If7 the taxing authority uses a multirate approach] For the purpose of setting rates as provided8 in section 137.073, this exclusion shall be made from the personal property class. The state9 tax commission shall provide each taxing authority with the total assessed value of business10 personal property within the jurisdiction of such taxing authority for which an appeal isHCS SS SCS SBs 1066 & 1088 1711 pending no later than August twentieth of each year. Whenever any appeal is resolved,12 whether by final adjudication or settlement, and the result of the appeal causes money to be13 paid to the taxing authority, the taxing authority shall not be required to make an additional14 adjustment to its rate or rates due to such payment once the deadline for setting its rates, as15 provided by this chapter, has passed in a [taxable] tax year, but shall adjust its rate or rates16 due to such payment in the next rate setting cycle to offset the payment in the next [taxable]17 tax year. For the purposes of this section, the term "business personal property" means18 tangible personal property which is used in a trade or business or used for production of19 income and which has a determinable life of longer than one year except that supplies used by20 a business shall also be considered business personal property, but shall not include livestock,21 farm machinery, property subject to the motor vehicle registration provisions of chapter 301,22 property subject to the tables provided in section 137.078, the property of rural electric23 cooperatives under chapter 394, or property assessed by the state tax commission under24 chapters 151, 153, and 155, section 137.022, and sections 137.1000 to 137.1030.137.115. 1. (1) All other laws to the contrary notwithstanding, the assessor or the2 assessor's deputies in all counties of this state including the City of St. Louis shall annually3 make a list of all real and tangible personal property taxable in the assessor's city, county,4 town or district.5(2) Except as otherwise provided in subsection 3 of this section and section 137.078,6 the assessor shall annually assess all personal property at thirty-three and one-third percent of7 its true value in money as of January first of each calendar year.8(3) The assessor shall annually assess all real property, including any new9 construction and improvements to real property, and possessory interests in real property at10 the percent of its true value in money set in subsection 5 of this section. The true value in11 money of any possessory interest in real property in subclass (3), where such real property is12 on or lies within the ultimate airport boundary as shown by a federal airport layout plan, as13 defined by 14 CFR 151.5, of a commercial airport having a FAR Part 139 certification and14 owned by a political subdivision, shall be the otherwise applicable true value in money of any15 such possessory interest in real property, less the total dollar amount of costs paid by a party,16 other than the political subdivision, towards any new construction or improvements on such17 real property completed after January 1, 2008, and which are included in the above-18 mentioned possessory interest, regardless of the year in which such costs were incurred or19 whether such costs were considered in any prior year. The assessor shall annually assess all20 real property in the following manner: new assessed values shall be determined as of January21 first of each odd-numbered year and shall be entered in the assessor's books; those same22 assessed values shall apply in the following even-numbered year, except for new construction23 and property improvements which shall be valued as though they had been completed as ofHCS SS SCS SBs 1066 & 1088 1824 January first of the preceding odd-numbered year. The assessor may call at the office, place25 of doing business, or residence of each person required by this chapter to list property, and26 require the person to make a correct statement of all taxable tangible personal property owned27 by the person or under his or her care, charge or management, taxable in the county.28(4) On or before January first of each even-numbered year, the assessor shall prepare29 and submit a two-year assessment maintenance plan to the county governing body and the30 state tax commission for their respective approval or modification. The county governing31 body shall approve and forward such plan or its alternative to the plan to the state tax32 commission by February first. If the county governing body fails to forward the plan or its33 alternative to the plan to the state tax commission by February first, the assessor's plan shall34 be considered approved by the county governing body. If the state tax commission fails to35 approve a plan and if the state tax commission and the assessor and the governing body of the36 county involved are unable to resolve the differences, in order to receive state cost-share37 funds outlined in section 137.750, the county or the assessor shall petition the administrative38 hearing commission, by May first, to decide all matters in dispute regarding the assessment39 maintenance plan. Upon agreement of the parties, the matter may be stayed while the parties40 proceed with mediation or arbitration upon terms agreed to by the parties. The final decision41 of the administrative hearing commission shall be subject to judicial review in the circuit42 court of the county involved.43(5) In the event a valuation of subclass (1) real property or subclass (3) real44 property within any county with a charter form of government, or within a city not within a45 county, is made by a computer, computer-assisted method or a computer program, the burden46 of proof, supported by clear, convincing and cogent evidence to sustain such valuation, shall47 be on the assessor at any hearing or appeal. In any such county, unless the assessor proves48 otherwise, there shall be a presumption that the assessment was made by a computer,49 computer-assisted method or a computer program. Such evidence shall include, but shall not50 be limited to, the following:51[(1)] (a) The findings of the assessor based on an appraisal of the property by52 generally accepted appraisal techniques; and53[(2)] (b) The purchase prices from sales of at least three comparable properties and54 the address or location thereof. As used in this subdivision, the word "comparable" means55 that:56[(a)] a. Such sale was closed at a date relevant to the property valuation; and57[(b)] b. Such properties are not more than one mile from the site of the disputed58 property, except where no similar properties exist within one mile of the disputed property,59 the nearest comparable property shall be used. Such property shall be within five hundredHCS SS SCS SBs 1066 & 1088 1960 square feet in size of the disputed property, and resemble the disputed property in age, floor61 plan, number of rooms, and other relevant characteristics.622. Assessors in each county of this state and the City of St. Louis may send personal63 property assessment forms through the mail.643. The following items of personal property shall each constitute separate subclasses65 of tangible personal property and shall be assessed and valued for the purposes of taxation at66 the following percentages of their true value in money:67(1) Grain and other agricultural crops in an unmanufactured condition, one-half of68 one percent;69(2) Livestock, twelve percent;70(3) Farm machinery, twelve percent;71(4) Motor vehicles which are eligible for registration as and are registered as historic72 motor vehicles pursuant to section 301.131 and aircraft which are at least twenty-five years73 old and which are used solely for noncommercial purposes and are operated less than two74 hundred hours per year or aircraft that are home built from a kit, five percent;75(5) Poultry, twelve percent;76(6) Tools and equipment used for pollution control and tools and equipment used in77 retooling for the purpose of introducing new product lines or used for making improvements78 to existing products by any company which is located in a state enterprise zone and which is79 identified by any standard industrial classification number cited in subdivision (7) of section80 135.200, twenty-five percent; and81(7) Solar panels, racking systems, inverters, and related solar equipment, components,82 materials, and supplies installed in connection with solar photovoltaic energy systems, as83 described in subdivision (46) of subsection 2 of section 144.030, that were constructed and84 producing solar energy prior to August 9, 2022, five percent.854. The person listing the property shall enter a true and correct statement of the86 property, in a printed blank prepared for that purpose. The statement, after being filled out,87 shall be signed and either affirmed or sworn to as provided in section 137.155. The list shall88 then be delivered to the assessor.895. (1) All subclasses of real property, as such subclasses are established in Section 490 (b) of Article X of the Missouri Constitution and defined in section 137.016, shall be assessed91 at the following percentages of true value:92(a) For real property in subclass (1), nineteen percent;93(b) For real property in subclass (2), twelve percent; and94(c) For real property in subclass (3), thirty-two percent.95(2) A taxpayer may apply to the county assessor, or, if not located within a county,96 then the assessor of such city, for the reclassification of such taxpayer's real property if the useHCS SS SCS SBs 1066 & 1088 2097 or purpose of such real property is changed after such property is assessed under the98 provisions of this chapter. If the assessor determines that such property shall be reclassified,99 he or she shall determine the assessment under this subsection based on the percentage of the100 tax year that such property was classified in each subclassification.1016. Manufactured homes, as defined in section 700.010, which are actually used as102 dwelling units shall be assessed at the same percentage of true value as residential real103 property for the purpose of taxation. The percentage of assessment of true value for such104 manufactured homes shall be the same as for residential real property. If the county collector105 cannot identify or find the manufactured home when attempting to attach the manufactured106 home for payment of taxes owed by the manufactured home owner, the county collector may107 request the county commission to have the manufactured home removed from the tax books,108 and such request shall be granted within thirty days after the request is made; however, the109 removal from the tax books does not remove the tax lien on the manufactured home if it is110 later identified or found. For purposes of this section, a manufactured home located in a111 manufactured home rental park, rental community or on real estate not owned by the112 manufactured home owner shall be considered personal property. For purposes of this113 section, a manufactured home located on real estate owned by the manufactured home owner114 may be considered real property.1157. Each manufactured home assessed shall be considered a parcel for the purpose of116 reimbursement pursuant to section 137.750, unless the manufactured home is deemed to be117 real estate as defined in subsection 7 of section 442.015 and assessed as a realty improvement118 to the existing real estate parcel.1198. Any amount of tax due and owing based on the assessment of a manufactured120 home shall be included on the personal property tax statement of the manufactured home121 owner unless the manufactured home is deemed to be real estate as defined in subsection 7 of122 section 442.015, in which case the amount of tax due and owing on the assessment of the123 manufactured home as a realty improvement to the existing real estate parcel shall be124 included on the real property tax statement of the real estate owner.1259. The assessor of each county and each city not within a county shall use a nationally126 recognized automotive trade publication such as the National Automobile Dealers'127 Association Official Used Car Guide, Kelley Blue Book, Edmunds, or other similar128 publication as the recommended guide of information for determining the true value of motor129 vehicles described in such publication. The state tax commission shall select and make130 available to all assessors which publication shall be used. The assessor of each county and131 each city not within a county shall use the trade-in value published in the current October132 issue of the publication selected by the state tax commission. The assessor shall not use a133 value that is greater than the average trade-in value in determining the true value of the motorHCS SS SCS SBs 1066 & 1088 21134 vehicle without performing a physical inspection of the motor vehicle. For vehicles two years135 old or newer from a vehicle's model year, the assessor may use a value other than average136 without performing a physical inspection of the motor vehicle. In the absence of a listing for137 a particular motor vehicle in such publication, the assessor shall use such information or138 publications that, in the assessor's judgment, will fairly estimate the true value in money of139 the motor vehicle. For motor vehicles with a true value of less than fifty thousand dollars as140 of January 1, 2025, the assessor shall not assess such motor vehicle for an amount greater141 than such motor vehicle was assessed in the previous year, provided that such motor vehicle142 was properly assessed in the previous year.14310. Before the assessor may increase the assessed valuation of any parcel of subclass144 (1) real property or any parcel of subclass (3) real property by more than fifteen percent145 since the last assessment, excluding increases due to new construction or improvements, the146 assessor shall conduct a physical inspection of such property.14711. If a physical inspection is required, pursuant to subsection 10 of this section, the148 assessor shall notify the property owner of that fact in writing and shall provide the owner149 clear written notice of the owner's rights relating to the physical inspection. If a physical150 inspection is required, the property owner may request that an interior inspection be151 performed during the physical inspection. The owner shall have no less than thirty days to152 notify the assessor of a request for an interior physical inspection.15312. A physical inspection, as required by subsection 10 of this section, shall include,154 but not be limited to, an on-site personal observation and review of all exterior portions of the155 land and any buildings and improvements to which the inspector has or may reasonably and156 lawfully gain external access, and shall include an observation and review of the interior of157 any buildings or improvements on the property upon the timely request of the owner pursuant158 to subsection 11 of this section. Mere observation of the property via a drive-by inspection or159 the like shall not be considered sufficient to constitute a physical inspection as required by160 this section.16113. A county or city collector may accept credit cards as proper form of payment of162 outstanding property tax or license due.

An eligible taxpayer shall not claim more than one primary residence;15(4) "Initial credit year":16(a) In the case of a taxpayer that meets all requirements of subdivision (2) of this17 subsection prior to the year in which a credit is authorized pursuant to subsection 2 of this18 section, the year in which such credit is authorized;19(b) For all other taxpayers, the year in which the taxpayer meets all requirements of20 subdivision (2) of this subsection.2122 If in any tax year subsequent to the eligible taxpayer's initial credit year the eligible taxpayer's23 real property tax liability is lower than such liability in the initial credit year, such tax year24 shall be considered the eligible taxpayer's initial credit year for all subsequent tax years. This25 provision shall not apply if an eligible taxpayer's real property tax liability is lower than such26 liability in the taxpayer's initial credit year solely due to a reduction in a property tax levy27 made pursuant to section 321.554.282. (1) Any county authorized to impose a property tax may grant a property tax credit29 to all eligible taxpayers residing in such county for certain increases to such taxpayer'sHCS SS SCS SBs 1066 & 1088 2430 real property tax liability in an amount equal to the taxpayer's eligible credit amount,31 provided that:32(a) Such county adopts an ordinance authorizing such credit; or33(b) a.

The ballot of submission for the question submitted to the voters pursuant to38 paragraph (b) of this subdivision shall be in substantially the following form:39Shall the County of ______ exempt senior citizens aged 62 and40older from increases in the property tax liability due on such41senior citizens' primary residence?42YES NO4344 If a majority of the votes cast on the proposal by the qualified voters voting thereon are in45 favor of the proposal, then the credit shall be in effect.46(2) An ordinance adopted pursuant to paragraph (a) of subdivision (1) of this47 subsection shall not preclude such ordinance from being amended or superseded by a petition48 subsequently adopted pursuant to paragraph (b) of subdivision (1) of this subsection.493. (1) In a county granting a real property tax credit pursuant to this section, the50 county and each political subdivision levying a real property tax on an eligible51 taxpayer's homestead shall apply the county's or political subdivision's proportional52 amount of such credit when calculating the eligible taxpayer's property tax liability for the53 tax year. The total amount of the credit and the county's and each political subdivision's54 proportional amount of the credit shall be noted in actual monetary value on the55 statement of tax due sent to the eligible taxpayer by the county collector. A note on the56 statement of tax due shall indicate that it is the responsibility of the taxpayer to notify57 the county if he or she is no longer eligible for the credit provided under this section.58 Such ineligibility shall include, but not be limited to, circumstances in which the59 taxpayer is no longer the owner of record, is no longer liable for the payment of60 property taxes on the qualifying residence, or no longer occupies the qualifying61 residence due to death or relocation, or the qualifying residence is no longer such62 taxpayer's primary residence. Failure to notify the county governing body of63 ineligibility may result in penalties described in this section. The county governing64 body or political subdivision's governing body may adopt reasonable procedures in order to65 carry out the purposes and intent of this section, provided that neither the county nor aHCS SS SCS SBs 1066 & 1088 2566 political subdivision shall [not] adopt any procedure that limits the definition or scope of67 eligible credit amount or eligible taxpayer as defined in this section.68(2) If an eligible taxpayer makes new construction and improvements to such eligible69 taxpayer's homestead, the real property tax liability for the taxpayer's initial credit year shall70 be increased to reflect the real property tax liability attributable to such new construction and71 improvements.72(3) If an eligible taxpayer's homestead is annexed into a taxing jurisdiction to which73 such eligible taxpayer did not owe real property tax in the eligible taxpayer's initial credit74 year, then the real property tax liability for the taxpayer's initial credit year shall be increased75 to reflect the real property tax liability owed to the annexing taxing jurisdiction.764. For the purposes of calculating property tax levies pursuant to section 137.073, the77 total amount of credits authorized [by] in a county pursuant to this section shall be considered78 tax revenue, as such term is defined in section 137.073, actually received by the political79 subdivision levying such tax.805. [A county granting a tax credit pursuant to this section shall notify each political81 subdivision within such county of the total credit amount applicable to such political82 subdivision by no later than November thirtieth of each year] For purposes of this section,83 "real property tax" includes, but is not limited to, the following levies on an eligible84 taxpayer's homestead by a county or a political subdivision within such county:85(1) A tax levy for debt service;86(2) A tax levy for operating purposes or operating expenses;87(3) A tax levy for capital improvements or capital projects;88(4) A special assessment or special tax levy; and89(5) Any other real property tax levied for any purpose.906. Nothing in this section shall be construed to prevent an eligible taxpayer from91 appealing an assessment.927. For all tax years beginning on or after the effective date of this section, an93 eligible taxpayer applying for the tax credit authorized under the provisions of this94 section shall not be required to reapply annually. Upon initial qualification under the95 provisions of this section and any additional provisions adopted by the county governing96 body, the eligible taxpayer shall maintain such eligibility without a requirement to97 reapply for qualification each year. The tax credit shall continue to be automatically98 applied to the eligible taxpayer's homestead until the tax year in which the eligible99 taxpayer relocates to another homestead or upon the death of the eligible taxpayer,100 which shall be certified with a copy of the death certificate or notification of the101 relocation within ninety days of the date of either such event. If a credit is granted inHCS SS SCS SBs 1066 & 1088 26102 error due to the failure of the taxpayer to notify the county collector of relocation or103 death, the governing body of the county may remedy the error.1048. The department of health and senior services shall, subject to appropriation105 by the general assembly, establish and maintain a secure electronic portal accessible to106 each county, through a county designee authorized to administer or assist in107 administering any senior citizen property tax credit program authorized under this108 section for the limited purpose of verifying whether an applicant is deceased. Such109 portal shall permit authorized county designees to access or query records necessary to110 determine the death status of applicants in order to ensure the accurate and lawful111 administration of such tax credit.1129. In the event no appropriation is made for the establishment or maintenance of113 such portal, the department of health and senior services shall, no later than July114 thirtieth of each year, provide to each county, through its authorized county designee, a115 report listing all individuals whose deaths were recorded within that county during the116 period beginning July first of the immediately preceding year and ending June thirtieth117 of the current year. Such report shall be provided in a format reasonably usable by the118 county designee for purposes of administering, verifying, and maintaining eligibility for119 the senior citizen property tax credit.12010. Each county designee, in furtherance of administering any senior citizen121 property tax credit eliminating the need for mandatory annual renewal by eligible122 applicants, shall implement reasonable procedures to determine whether a change of123 ownership has occurred with respect to any homestead receiving such credit prior to the124 issuance of property tax statements for the applicable tax year. Such procedures shall125 conform to applicable local ordinances, administrative processes, and available records,126 and shall ensure the accurate continuation or removal of such credit based upon127 eligibility.12811. Any payment of real or personal property taxes transmitted through the129 United States Postal Service and postmarked no later than January fifth of the year130 immediately following the applicable tax year shall be deemed timely paid and shall not131 be subject to penalty or interest, provided that, regardless of postmark date, any check,132 cashier's check, or money order dated later than December thirty-first of the applicable133 tax year shall be considered delinquent, and further provided that any payment made134 by means other than United States Postal Service mail, including but not limited to in-135 person, electronic, internet, interactive voice response, or electronic check payments136 shall be considered delinquent if received after December thirty-first of the applicable137 tax year.HCS SS SCS SBs 1066 & 1088 2713812. Notwithstanding any provision of law to the contrary, in any county139 operating under a township form of government, the township collector, or other county140 designee authorized to collect property taxes, shall have the same authority as provided141 to county collectors under section 139.053 to accept partial or installment payments of142 real and personal property taxes prior to delinquency. Such township collector or143 county designee may establish reasonable procedures for the acceptance, processing,144 safeguarding, and accounting of such installment payments consistent with state law145 and local ordinances, and taxpayers within such jurisdictions shall have the same rights146 and opportunities to remit property taxes through installment payments as taxpayers in147 counties without a township form of government.14813. Notwithstanding any provision of law to the contrary, in the event a county149 experiences technical, administrative, or operational difficulties that materially delay150 the preparation, printing, or mailing of real or personal property tax statements, the151 county governing body may extend the deadline for timely payment of such taxes for a152 period not to exceed thirty days beyond the otherwise applicable delinquency date.153 During such extension period, payments received shall be deemed timely and shall not154 be subject to penalty or interest. The county governing body shall provide reasonable155 public notice of such extension, and such extension shall apply uniformly to all affected156 taxpayers within the jurisdiction.15714. Notwithstanding any provision of law to the contrary, the county assessor,158 township assessor, or other county designee responsible for the administration of159 assessment lists, personal property declarations, homestead verification forms, or other160 assessment-related filings may allow a grace period not to exceed ten days following the161 statutory deadline for submission of such forms when such forms are transmitted162 through the United States Postal Service and postmarked on or before the applicable163 due date but received after such due date due to postal delay. Any such form received164 within the authorized grace period shall be deemed timely filed and shall not result in165 penalty, estimated assessment, or disqualification from any property tax credit or relief166 program solely due to delayed receipt. The assessor or county designee may establish167 reasonable procedures to verify postmark dates and ensure uniform and consistent168 application of such grace period in accordance with state law.137.1055. 1.
