SECOND REGULAR SESSION
HOUSE BILL NO. 3271
103RD GENERAL ASSEMBLY
INTRODUCED BY REPRESENTATIVE STRICKLER.
7019H.01I JOSEPH ENGLER, Chief Clerk
AN ACT
To repeal sections 137.073, 137.079, and 137.115, RSMo, and to enact in lieu thereof three
new sections relating to taxation of property.
Be it enacted by the General Assembly of the state of Missouri, as follows:
Section A. Sections 137.073, 137.079, and 137.115, RSMo, are repealed and three
new sections enacted in lieu thereof, to be known as sections 137.073, 137.079, and 137.115,
to read as follows:
137.073. 1. As used in this section, the following terms mean:
(1) "General reassessment", changes in value, entered in the assessor's books, of a
substantial portion of the parcels of real property within a county resulting wholly or partly
from reappraisal of value or other actions of the assessor or county equalization body or
ordered by the state tax commission or any court;
(2) "Tax rate", "rate", or "rate of levy", singular or plural, includes the tax rate for
each purpose of taxation of property a taxing authority is authorized to levy without a vote
and any tax rate authorized by election, including bond interest and sinking fund;
(3) "Tax rate ceiling", a tax rate as revised by the taxing authority to comply with the
provisions of this section or when a court has determined the tax rate; except that, other
provisions of law to the contrary notwithstanding, a school district may levy the operating
levy for school purposes required for the current year pursuant to subsection 2 of section
163.021, less all adjustments required pursuant to Article X, Section 22 of the Missouri
Constitution, if such tax rate does not exceed the highest tax rate in effect subsequent to the
1980 tax year. This is the maximum tax rate that may be levied, unless a higher tax rate
ceiling is approved by voters of the political subdivision as provided in this section;
EXPLANATION — Matter enclosed in bold-faced brackets [thus] in the above bill is not enacted and is
intended to be omitted from the law. Matter in bold-face type in the above bill is proposed language.
HB 3271 2
(4) "Tax revenue", when referring to the previous year, means the actual receipts from
ad valorem levies on all classes of property, including state-assessed property, in the
immediately preceding fiscal year of the political subdivision, plus an allowance for taxes
billed but not collected in the fiscal year and plus an additional allowance for the revenue
which would have been collected from property which was annexed by such political
subdivision but which was not previously used in determining tax revenue pursuant to this
section. The term "tax revenue" shall not include any receipts from ad valorem levies on any
property of a railroad corporation or a public utility, as these terms are defined in section
386.020, which were assessed by the assessor of a county or city in the previous year but are
assessed by the state tax commission in the current year. All school districts and those
counties levying sales taxes pursuant to chapter 67 shall include in the calculation of tax
revenue an amount equivalent to that by which they reduced property tax levies as a result of
sales tax pursuant to section 67.505 and section 164.013 [or as excess home dock city or
county fees as provided in subsection 4 of section 313.820] in the immediately preceding
fiscal year but not including any amount calculated to adjust for prior years. For purposes of
political subdivisions which were authorized to levy a tax in the prior year but which did not
levy such tax or levied a reduced rate, the term "tax revenue", as used in relation to the
revision of tax levies mandated by law, shall mean the revenues equal to the amount that
would have been available if the voluntary rate reduction had not been made.
2. Whenever changes in assessed valuation are entered in the assessor's books for any
personal property, in the aggregate, or for any subclass of real property as such subclasses are
established in Section 4(b) of Article X of the Missouri Constitution and defined in section
137.016, the county clerk in all counties and the assessor of St. Louis City shall notify each
political subdivision wholly or partially within the county or St. Louis City of the change in
valuation of each subclass of real property, individually, and personal property, in the
aggregate, exclusive of new construction and improvements. All political subdivisions shall
immediately revise the applicable rates of levy for each purpose for each subclass of real
property, individually, and personal property, in the aggregate, for which taxes are levied to
the extent necessary to produce from all taxable property, exclusive of new construction and
improvements, substantially the same amount of tax revenue as was produced in the previous
year for each subclass of real property, individually, and personal property, in the aggregate,
except that the rate shall not exceed the greater of the most recent voter-approved rate or the
most recent voter-approved rate as adjusted under subdivision (2) of subsection 5 of this
section. Any political subdivision that has received approval from voters for a tax increase
after August 27, 2008, may levy a rate to collect substantially the same amount of tax revenue
as the amount of revenue that would have been derived by applying the voter-approved
increased tax rate ceiling to the total assessed valuation of the political subdivision as most
HB 3271 3
recently certified by the city or county clerk on or before the date of the election in which
such increase is approved, increased by the percentage increase in the consumer price index,
as provided by law, except that the [rate] rates of levy for each subclass of real property,
individually, and personal property, in the aggregate, shall not exceed the greater of the
most recent voter-approved rate or the most recent voter-approved rate as adjusted under
subdivision (2) of subsection 5 of this section. Such tax revenue shall not include any receipts
from ad valorem levies on any real property which was assessed by the assessor of a county
or city in such previous year but is assessed by the assessor of a county or city in the current
year in a different subclass of real property. Where the taxing authority is a school district for
the purposes of revising the applicable rates of levy for each subclass of real property, the tax
revenues from state-assessed railroad and utility property shall be apportioned and attributed
to each subclass of real property based on the percentage of the total assessed valuation of the
county that each subclass of real property represents in the current [taxable] tax year. As
provided in Section 22 of Article X of the constitution, a political subdivision may also revise
each levy to allow for inflationary assessment growth occurring within the political
subdivision. The inflationary growth factor for any such subclass of real property or personal
property shall be limited to the actual assessment growth in such subclass or class, exclusive
of new construction and improvements, and exclusive of the assessed value on any real
property which was assessed by the assessor of a county or city in the current year in a
different subclass of real property, but not to exceed the consumer price index or five percent,
whichever is lower. [Should the tax revenue of a political subdivision from the various tax
rates determined in this subsection be different than the tax revenue that would have been
determined from a single tax rate as calculated pursuant to the method of calculation in this
subsection prior to January 1, 2003, then the political subdivision shall revise the tax rates of
those subclasses of real property, individually, and/or personal property, in the aggregate, in
which there is a tax rate reduction, pursuant to the provisions of this subsection. Such
revision shall yield an amount equal to such difference and shall be apportioned among such
subclasses of real property, individually, and/or personal property, in the aggregate, based on
the relative assessed valuation of the class or subclasses of property experiencing a tax rate
reduction. Such revision in the tax rates of each class or subclass shall be made by computing
the percentage of current year adjusted assessed valuation of each class or subclass with a tax
rate reduction to the total current year adjusted assessed valuation of the class or subclasses
with a tax rate reduction, multiplying the resulting percentages by the revenue difference
between the single rate calculation and the calculations pursuant to this subsection and
dividing by the respective adjusted current year assessed valuation of each class or subclass to
determine the adjustment to the rate to be levied upon each class or subclass of property. The
adjustment computed herein shall be multiplied by one hundred, rounded to four decimals in
HB 3271 4
the manner provided in this subsection, and added to the initial rate computed for each class
or subclass of property. For school districts that levy separate tax rates on each subclass of
real property and personal property in the aggregate, if voters approved a ballot before
January 1, 2011, that presented separate stated tax rates to be applied to the different
subclasses of real property and personal property in the aggregate, or increases the separate
rates that may be levied on the different subclasses of real property and personal property in
the aggregate by different amounts, the tax rate that shall be used for the single tax rate
calculation shall be a blended rate, calculated in the manner provided under subdivision (1) of
subsection 6 of this section.] Notwithstanding any provision of this subsection to the
contrary, no revision to the rate of levy for personal property shall cause such levy to increase
over the levy for personal property from the prior year.
3. (1) Where the taxing authority is a school district, it shall be required to revise the
rates of levy to the extent necessary to produce from all taxable property, including state-
assessed railroad and utility property, which shall be separately estimated in addition to other
data required in complying with section 164.011, substantially the amount of tax revenue
permitted in this section. In the year following tax rate reduction, the tax rate ceiling may be
adjusted to offset such district's reduction in the apportionment of state school moneys due to
its reduced tax rate. However, in the event any school district, in calculating a tax rate ceiling
pursuant to this section, requiring the estimating of effects of state-assessed railroad and
utility valuation or loss of state aid, discovers that the estimates used result in receipt of
excess revenues, which would have required a lower rate if the actual information had been
known, the school district shall reduce the tax rate ceiling in the following year to compensate
for the excess receipts, and the recalculated rate shall become the tax rate ceiling for purposes
of this section.
(2) For any political subdivision which experiences a reduction in the amount of
assessed valuation relating to a prior year, due to decisions of the state tax commission or a
court pursuant to sections 138.430 to 138.433, or due to clerical errors or corrections in the
calculation or recordation of any assessed valuation:
(a) Such political subdivision may revise the tax rate ceiling for each purpose it levies
taxes to compensate for the reduction in assessed value occurring after the political
subdivision calculated the tax rate ceiling for the particular subclass of real property or for
personal property, in the aggregate, in a prior year. Such revision by the political subdivision
shall be made at the time of the next calculation of the tax rate for the particular subclass of
real property or for personal property, in the aggregate, after the reduction in assessed
valuation has been determined and shall be calculated in a manner that results in the revised
tax rate ceiling being the same as it would have been had the corrected or finalized assessment
been available at the time of the prior calculation;
HB 3271 5
(b) In addition, for up to three years following the determination of the reduction in
assessed valuation as a result of circumstances defined in this subdivision, such political
subdivision may levy a tax rate for each purpose it levies taxes above the revised tax rate
ceiling provided in paragraph (a) of this subdivision to recoup any revenues it was entitled to
receive had the corrected or finalized assessment been available at the time of the prior
calculation.
4. (1) In order to implement the provisions of this section and Section 22 of Article X
of the Constitution of Missouri, the term improvements shall apply to both real and personal
property. In order to determine the value of new construction and improvements, each county
assessor shall maintain a record of real property valuations in such a manner as to identify
each year the increase in valuation for each political subdivision in the county as a result of
new construction and improvements. The value of new construction and improvements shall
include the additional assessed value of all improvements or additions to real property which
were begun after and were not part of the prior year's assessment, except that the additional
assessed value of all improvements or additions to real property which had been totally or
partially exempt from ad valorem taxes pursuant to sections 99.800 to 99.865, sections
135.200 to 135.255, and section 353.110 shall be included in the value of new construction
and improvements when the property becomes totally or partially subject to assessment and
payment of all ad valorem taxes. The aggregate increase in valuation of personal property for
the current year over that of the previous year is the equivalent of the new construction and
improvements factor for personal property. [Notwithstanding any opt-out implemented
pursuant to subsection 14 of section 137.115,] The assessor shall certify the amount of new
construction and improvements and the amount of assessed value on any real property which
was assessed by the assessor of a county or city in such previous year but is assessed by the
assessor of a county or city in the current year in a different subclass of real property
separately for each of the three subclasses of real property for each political subdivision to the
county clerk in order that political subdivisions shall have this information for the purpose of
calculating tax rates pursuant to this section and Section 22, Article X, Constitution of
Missouri. In addition, the state tax commission shall certify each year to each county clerk
the increase in the general price level as measured by the Consumer Price Index for All Urban
Consumers for the United States, or its successor publications, as defined and officially
reported by the United States Department of Labor, or its successor agency. The state tax
commission shall certify the increase in such index on the latest twelve-month basis available
on February first of each year over the immediately preceding prior twelve-month period in
order that political subdivisions shall have this information available in setting their tax rates
according to law and Section 22 of Article X of the Constitution of Missouri. For purposes of
implementing the provisions of this section and Section 22 of Article X of the Missouri
HB 3271 6
Constitution, the term "property" means all taxable property, including state-assessed
property.
(2) Each political subdivision required to revise rates of levy pursuant to this section
or Section 22 of Article X of the Constitution of Missouri shall calculate each tax rate it is
authorized to levy and, in establishing each tax rate, shall consider each provision for tax rate
revision provided in this section and Section 22 of Article X of the Constitution of Missouri,
separately and without regard to annual tax rate reductions provided in section 67.505 and
section 164.013. Each political subdivision shall set each tax rate it is authorized to levy
using the calculation that produces the lowest tax rate ceiling. It is further the intent of the
general assembly, pursuant to the authority of Section 10(c) of Article X of the Constitution
of Missouri, that the provisions of such section be applicable to tax rate revisions mandated
pursuant to Section 22 of Article X of the Constitution of Missouri as to reestablishing tax
rates as revised in subsequent years, enforcement provisions, and other provisions not in
conflict with Section 22 of Article X of the Constitution of Missouri. Annual tax rate
reductions provided in section 67.505 and section 164.013 shall be applied to the tax rate as
established pursuant to this section and Section 22 of Article X of the Constitution of
Missouri, unless otherwise provided by law.
5. (1) In all political subdivisions, the tax rate ceiling established pursuant to this
section shall not be increased unless approved by a vote of the people. Approval of the higher
tax rate shall be by at least a majority of votes cast. When a proposed higher tax rate requires
approval by more than a simple majority pursuant to any provision of law or the constitution,
the tax rate increase must receive approval by at least the majority required.
(2) When voters approve an increase in the tax rate, the amount of the increase shall
be added to the tax rate ceiling as calculated pursuant to this section to the extent the total rate
does not exceed any maximum rate prescribed by law. If a ballot question presents a stated
tax rate for approval rather than describing the amount of increase in the question, the stated
tax rate approved shall be adjusted as provided in this section and, so adjusted, shall be the
current tax rate ceiling. The increased tax rate ceiling as approved shall be adjusted such that
when applied to the current total assessed valuation of the political subdivision, excluding
new construction and improvements since the date of the election approving such increase,
the revenue derived from the adjusted tax rate ceiling is equal to the sum of: the amount of
revenue which would have been derived by applying the voter-approved increased tax rate
ceiling to total assessed valuation of the political subdivision, as most recently certified by the
city or county clerk on or before the date of the election in which such increase is approved,
increased by the percentage increase in the consumer price index, as provided by law. Such
adjusted tax rate ceiling may be applied to the total assessed valuation of the political
subdivision at the setting of the next tax rate. If a ballot question presents a phased-in tax rate
HB 3271 7
increase, upon voter approval, each tax rate increase shall be adjusted in the manner
prescribed in this section to yield the sum of: the amount of revenue that would be derived by
applying such voter-approved increased rate to the total assessed valuation, as most recently
certified by the city or county clerk on or before the date of the election in which such
increase was approved, increased by the percentage increase in the consumer price index, as
provided by law, from the date of the election to the time of such increase and, so adjusted,
shall be the current tax rate ceiling.
(3) The governing body of any political subdivision may levy a tax rate lower than its
tax rate ceiling and may, in a nonreassessment year, increase that lowered tax rate to a level
not exceeding the tax rate ceiling without voter approval in the manner provided under
subdivision (4) of this subsection. Nothing in this section shall be construed as prohibiting a
political subdivision from voluntarily levying a tax rate lower than that which is required
under the provisions of this section or from seeking voter approval of a reduction to such
political subdivision's tax rate ceiling.
(4) In a year of general reassessment, a governing body whose tax rate is lower than
its tax rate ceiling shall revise its tax rate pursuant to the provisions of subsection 4 of this
section as if its tax rate was at the tax rate ceiling. In a year following general reassessment, if
such governing body intends to increase its tax rate, the governing body shall conduct a
public hearing, and in a public meeting it shall adopt an ordinance, resolution, or policy
statement justifying its action prior to setting and certifying its tax rate. The provisions of this
subdivision shall not apply to any political subdivision which levies a tax rate lower than its
tax rate ceiling solely due to a reduction required by law resulting from sales tax collections.
The provisions of this subdivision shall not apply to any political subdivision which has
received voter approval for an increase to its tax rate ceiling subsequent to setting its most
recent tax rate.
6. (1) For the purposes of calculating state aid for public schools pursuant to section
163.031, each taxing authority which is a school district shall determine its proposed tax rate
as a blended rate of the classes or subclasses of property. Such blended rate shall be
calculated by first determining the total tax revenue of the property within the jurisdiction of
the taxing authority, which amount shall be equal to the sum of the products of multiplying
the assessed valuation of each class and subclass of property by the corresponding tax rate for
such class or subclass, then dividing the total tax revenue by the total assessed valuation of
the same jurisdiction, and then multiplying the resulting quotient by a factor of one hundred.
Where the taxing authority is a school district, such blended rate shall also be used by such
school district for calculating revenue from state-assessed railroad and utility property as
defined in chapter 151 and for apportioning the tax rate by purpose.
HB 3271 8
(2) Each taxing authority proposing to levy a tax rate in any year shall notify the clerk
of the county commission in the county or counties where the tax rate applies of its tax rate
ceiling and its proposed tax rate. Each taxing authority shall express its proposed tax rate in a
fraction equal to the nearest one-tenth of a cent, unless its proposed tax rate is in excess of one
dollar, then one/one-hundredth of a cent. If a taxing authority shall round to one/one-
hundredth of a cent, it shall round up a fraction greater than or equal to five/one-thousandth of
one cent to the next higher one/one-hundredth of a cent; if a taxing authority shall round to
one-tenth of a cent, it shall round up a fraction greater than or equal to five/one-hundredths of
a cent to the next higher one-tenth of a cent. Any taxing authority levying a property tax rate
shall provide data, in such form as shall be prescribed by the state auditor by rule,
substantiating such tax rate complies with Missouri law. All forms for the calculation of rates
pursuant to this section shall be promulgated as a rule and shall not be incorporated by
reference. The state auditor shall promulgate rules for any and all forms for the calculation of
rates pursuant to this section which do not currently exist in rule form or that have been
incorporated by reference. In addition, each taxing authority proposing to levy a tax rate for
debt service shall provide data, in such form as shall be prescribed by the state auditor by rule,
substantiating the tax rate for debt service complies with Missouri law. A tax rate proposed
for annual debt service requirements will be prima facie valid if, after making the payment for
which the tax was levied, bonds remain outstanding and the debt fund reserves do not exceed
the following year's payments. The county clerk shall keep on file and available for public
inspection all such information for a period of three years. The clerk shall, within three days
of receipt, forward a copy of the notice of a taxing authority's tax rate ceiling and proposed
tax rate and any substantiating data to the state auditor. The state auditor shall, within fifteen
days of the date of receipt, examine such information and return to the county clerk his or her
findings as to compliance of the tax rate ceiling with this section and as to compliance of any
proposed tax rate for debt service with Missouri law. If the state auditor believes that a taxing
authority's proposed tax rate does not comply with Missouri law, then the state auditor's
findings shall include a recalculated tax rate, and the state auditor may request a taxing
authority to submit documentation supporting such taxing authority's proposed tax rate. The
county clerk shall immediately forward a copy of the auditor's findings to the taxing authority
and shall file a copy of the findings with the information received from the taxing authority.
The taxing authority shall have fifteen days from the date of receipt from the county clerk of
the state auditor's findings and any request for supporting documentation to accept or reject in
writing the rate change certified by the state auditor and to submit all requested information to
the state auditor. A copy of the taxing authority's acceptance or rejection and any information
submitted to the state auditor shall also be mailed to the county clerk. If a taxing authority
rejects a rate change certified by the state auditor and the state auditor does not receive
HB 3271 9
supporting information which justifies the taxing authority's original or any subsequent
proposed tax rate, then the state auditor shall refer the perceived violations of such taxing
authority to the attorney general's office and the attorney general is authorized to obtain
injunctive relief to prevent the taxing authority from levying a violative tax rate.
(3) In the event that the taxing authority incorrectly completes the forms created and
promulgated under subdivision (2) of this subsection, or makes a clerical error, the taxing
authority may submit amended forms with an explanation for the needed changes. If such
amended forms are filed under regulations prescribed by the state auditor, the state auditor
shall take into consideration such amended forms for the purposes of this subsection.
7. No tax rate shall be extended on the tax rolls by the county clerk unless the political
subdivision has complied with the foregoing provisions of this section.
8. Whenever a taxpayer has cause to believe that a taxing authority has not complied
with the provisions of this section, the taxpayer may make a formal complaint with the
prosecuting attorney of the county. Where the prosecuting attorney fails to bring an action
within ten days of the filing of the complaint, the taxpayer may bring a civil action pursuant to
this section and institute an action as representative of a class of all taxpayers within a taxing
authority if the class is so numerous that joinder of all members is impracticable, if there are
questions of law or fact common to the class, if the claims or defenses of the representative
parties are typical of the claims or defenses of the class, and if the representative parties will
fairly and adequately protect the interests of the class. In any class action maintained
pursuant to this section, the court may direct to the members of the class a notice to be
published at least once each week for four consecutive weeks in a newspaper of general
circulation published in the county where the civil action is commenced and in other counties
within the jurisdiction of a taxing authority. The notice shall advise each member that the
court will exclude him or her from the class if he or she so requests by a specified date, that
the judgment, whether favorable or not, will include all members who do not request
exclusion, and that any member who does not request exclusion may, if he or she desires,
enter an appearance. In any class action brought pursuant to this section, the court, in
addition to the relief requested, shall assess against the taxing authority found to be in
violation of this section the reasonable costs of bringing the action, including reasonable
attorney's fees, provided no attorney's fees shall be awarded any attorney or association of
attorneys who receive public funds from any source for their services. Any action brought
pursuant to this section shall be set for hearing as soon as practicable after the cause is at
issue.
9. If in any action, including a class action, the court issues an order requiring a taxing
authority to revise the tax rates as provided in this section or enjoins a taxing authority from
the collection of a tax because of its failure to revise the rate of levy as provided in this
HB 3271 10
section, any taxpayer paying his or her taxes when an improper rate is applied has erroneously
paid his or her taxes in part, whether or not the taxes are paid under protest as provided in
section 139.031 or otherwise contested. The part of the taxes paid erroneously is the
difference in the amount produced by the original levy and the amount produced by the
revised levy. The township or county collector of taxes or the collector of taxes in any city
shall refund the amount of the tax erroneously paid. The taxing authority refusing to revise
the rate of levy as provided in this section shall make available to the collector all funds
necessary to make refunds pursuant to this subsection. No taxpayer shall receive any interest
on any money erroneously paid by him or her pursuant to this subsection. Effective in the
1994 tax year, nothing in this section shall be construed to require a taxing authority to refund
any tax erroneously paid prior to or during the third tax year preceding the current tax year.
10. Any rule or portion of a rule, as that term is defined in section 536.010, that is
created under the authority delegated in this section shall become effective only if it complies
with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028.
This section and chapter 536 are nonseverable and if any of the powers vested with the
general assembly pursuant to chapter 536 to review, to delay the effective date, or to
disapprove and annul a rule are subsequently held unconstitutional, then the grant of
rulemaking authority and any rule proposed or adopted after August 28, 2004, shall be invalid
and void.
137.079. Prior to setting its [rate or] rates as required by section 137.073, each taxing
authority shall exclude from its total assessed valuation seventy-two percent of the total
amount of assessed value of business personal property that is the subject of an appeal at the
state tax commission or in a court of competent jurisdiction in this state. This exclusion shall
only apply to the portion of the assessed value of business personal property that is disputed
in the appeal, and shall not exclude any portion of the same property that is not disputed. [If
the taxing authority uses a multirate approach] For the purpose of setting rates as provided
in section 137.073, this exclusion shall be made from the personal property class. The state
tax commission shall provide each taxing authority with the total assessed value of business
personal property within the jurisdiction of such taxing authority for which an appeal is
pending no later than August twentieth of each year. Whenever any appeal is resolved,
whether by final adjudication or settlement, and the result of the appeal causes money to be
paid to the taxing authority, the taxing authority shall not be required to make an additional
adjustment to its rate or rates due to such payment once the deadline for setting its rates, as
provided by this chapter, has passed in a taxable year, but shall adjust its rate or rates due to
such payment in the next rate setting cycle to offset the payment in the next taxable year. For
the purposes of this section, the term "business personal property" means tangible personal
property which is used in a trade or business or used for production of income and which has
HB 3271 11
a determinable life of longer than one year except that supplies used by a business shall also
be considered business personal property, but shall not include livestock, farm machinery,
property subject to the motor vehicle registration provisions of chapter 301, property subject
to the tables provided in section 137.078, the property of rural electric cooperatives under
chapter 394, or property assessed by the state tax commission under 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 the
assessor's deputies in all counties of this state including the City of St. Louis shall annually
make a list of all real and tangible personal property taxable in the assessor's city, county,
town or district.
(2) Except as otherwise provided in subsection 3 of this section and section 137.078,
the assessor shall annually assess all personal property at thirty-three and one-third percent of
its true value in money as of January first of each calendar year.
(3) The assessor shall annually assess all real property, including any new
construction and improvements to real property, and possessory interests in real property at
the percent of its true value in money set in subsection 5 of this section. The true value in
money of any possessory interest in real property in subclass (3), where such real property is
on or lies within the ultimate airport boundary as shown by a federal airport layout plan, as
defined by 14 CFR 151.5, of a commercial airport having a FAR Part 139 certification and
owned by a political subdivision, shall be the otherwise applicable true value in money of any
such possessory interest in real property, less the total dollar amount of costs paid by a party,
other than the political subdivision, towards any new construction or improvements on such
real property completed after January 1, 2008, and which are included in the above-
mentioned possessory interest, regardless of the year in which such costs were incurred or
whether such costs were considered in any prior year. The assessor shall annually assess all
real property in the following manner: new assessed values shall be determined as of January
first of each odd-numbered year and shall be entered in the assessor's books; those same
assessed values shall apply in the following even-numbered year, except for new construction
and property improvements which shall be valued as though they had been completed as of
January first of the preceding odd-numbered year. The assessor may call at the office, place
of doing business, or residence of each person required by this chapter to list property, and
require the person to make a correct statement of all taxable tangible personal property owned
by the person or under his or her care, charge or management, taxable in the county.
(4) On or before January first of each even-numbered year, the assessor shall prepare
and submit a two-year assessment maintenance plan to the county governing body and the
state tax commission for their respective approval or modification. The county governing
body shall approve and forward such plan or its alternative to the plan to the state tax
HB 3271 12
commission by February first. If the county governing body fails to forward the plan or its
alternative to the plan to the state tax commission by February first, the assessor's plan shall
be considered approved by the county governing body. If the state tax commission fails to
approve a plan and if the state tax commission and the assessor and the governing body of the
county involved are unable to resolve the differences, in order to receive state cost-share
funds outlined in section 137.750, the county or the assessor shall petition the administrative
hearing commission, by May first, to decide all matters in dispute regarding the assessment
maintenance plan. Upon agreement of the parties, the matter may be stayed while the parties
proceed with mediation or arbitration upon terms agreed to by the parties. The final decision
of the administrative hearing commission shall be subject to judicial review in the circuit
court of the county involved.
(5) In the event a valuation of subclass (1) real property within any county with a
charter form of government, or within a city not within a county, is made by a computer,
computer-assisted method or a computer program, the burden of proof, supported by clear,
convincing and cogent evidence to sustain such valuation, shall be on the assessor at any
hearing or appeal. In any such county, unless the assessor proves otherwise, there shall be a
presumption that the assessment was made by a computer, computer-assisted method or a
computer program. Such evidence shall include, but shall not be limited to, the following:
[(1)] (a) The findings of the assessor based on an appraisal of the property by
generally accepted appraisal techniques; and
[(2)] (b) The purchase prices from sales of at least three comparable properties and
the address or location thereof. As used in this subdivision, the word "comparable" means
that:
[(a)] a. Such sale was closed at a date relevant to the property valuation; and
[(b)] b. Such properties are not more than one mile from the site of the disputed
property, except where no similar properties exist within one mile of the disputed property,
the nearest comparable property shall be used. Such property shall be within five hundred
square feet in size of the disputed property, and resemble the disputed property in age, floor
plan, number of rooms, and other relevant characteristics.
2. Assessors in each county of this state and the City of St. Louis may send personal
property assessment forms through the mail.
3. The following items of personal property shall each constitute separate subclasses
of tangible personal property and shall be assessed and valued for the purposes of taxation at
the following percentages of their true value in money:
(1) Grain and other agricultural crops in an unmanufactured condition, one-half of
one percent;
(2) Livestock, twelve percent;
HB 3271 13
(3) Farm machinery, twelve percent;
(4) Motor vehicles which are eligible for registration as and are registered as historic
motor vehicles pursuant to section 301.131 and aircraft which are at least twenty-five years
old and which are used solely for noncommercial purposes and are operated less than two
hundred hours per year or aircraft that are home built from a kit, five percent;
(5) Poultry, twelve percent;
(6) Tools and equipment used for pollution control and tools and equipment used in
retooling for the purpose of introducing new product lines or used for making improvements
to existing products by any company which is located in a state enterprise zone and which is
identified by any standard industrial classification number cited in subdivision (7) of section
135.200, twenty-five percent; and
(7) Solar panels, racking systems, inverters, and related solar equipment, components,
materials, and supplies installed in connection with solar photovoltaic energy systems, as
described in subdivision (46) of subsection 2 of section 144.030, that were constructed and
producing solar energy prior to August 9, 2022, five percent.
4. The person listing the property shall enter a true and correct statement of the
property, in a printed blank prepared for that purpose. The statement, after being filled out,
shall be signed and either affirmed or sworn to as provided in section 137.155. The list shall
then be delivered to the assessor.
5. (1) All subclasses of real property, as such subclasses are established in Section 4
(b) of Article X of the Missouri Constitution and defined in section 137.016, shall be assessed
at the following percentages of true value:
(a) For real property in subclass (1), nineteen percent;
(b) For real property in subclass (2), twelve percent; and
(c) For real property in subclass (3), thirty-two percent.
(2) A taxpayer may apply to the county assessor, or, if not located within a county,
then the assessor of such city, for the reclassification of such taxpayer's real property if the use
or purpose of such real property is changed after such property is assessed under the
provisions of this chapter. If the assessor determines that such property shall be reclassified,
he or she shall determine the assessment under this subsection based on the percentage of the
tax year that such property was classified in each subclassification.
6. Manufactured homes, as defined in section 700.010, which are actually used as
dwelling units shall be assessed at the same percentage of true value as residential real
property for the purpose of taxation. The percentage of assessment of true value for such
manufactured homes shall be the same as for residential real property. If the county collector
cannot identify or find the manufactured home when attempting to attach the manufactured
home for payment of taxes owed by the manufactured home owner, the county collector may
HB 3271 14
request the county commission to have the manufactured home removed from the tax books,
and such request shall be granted within thirty days after the request is made; however, the
removal from the tax books does not remove the tax lien on the manufactured home if it is
later identified or found. For purposes of this section, a manufactured home located in a
manufactured home rental park, rental community or on real estate not owned by the
manufactured home owner shall be considered personal property. For purposes of this
section, a manufactured home located on real estate owned by the manufactured home owner
may be considered real property.
7. Each manufactured home assessed shall be considered a parcel for the purpose of
reimbursement pursuant to section 137.750, unless the manufactured home is deemed to be
real estate as defined in subsection 7 of section 442.015 and assessed as a realty improvement
to the existing real estate parcel.
8. Any amount of tax due and owing based on the assessment of a manufactured
home shall be included on the personal property tax statement of the manufactured home
owner unless the manufactured home is deemed to be real estate as defined in subsection 7 of
section 442.015, in which case the amount of tax due and owing on the assessment of the
manufactured home as a realty improvement to the existing real estate parcel shall be
included on the real property tax statement of the real estate owner.
9. The assessor of each county and each city not within a county shall use a nationally
recognized automotive trade publication such as the National Automobile Dealers'
Association Official Used Car Guide, Kelley Blue Book, Edmunds, or other similar
publication as the recommended guide of information for determining the true value of motor
vehicles described in such publication. The state tax commission shall select and make
available to all assessors which publication shall be used. The assessor of each county and
each city not within a county shall use the trade-in value published in the current October
issue of the publication selected by the state tax commission. The assessor shall not use a
value that is greater than the average trade-in value in determining the true value of the motor
vehicle without performing a physical inspection of the motor vehicle. For vehicles two years
old or newer from a vehicle's model year, the assessor may use a value other than average
without performing a physical inspection of the motor vehicle. In the absence of a listing for
a particular motor vehicle in such publication, the assessor shall use such information or
publications that, in the assessor's judgment, will fairly estimate the true value in money of
the motor vehicle. For motor vehicles with a true value of less than fifty thousand dollars as
of January 1, 2025, the assessor shall not assess such motor vehicle for an amount greater
than such motor vehicle was assessed in the previous year, provided that such motor vehicle
was properly assessed in the previous year.
HB 3271 15
10. Before the assessor may increase the assessed valuation of any parcel of subclass
(1) real property or any parcel of subclass (3) real property by more than fifteen percent
since the last assessment, excluding increases due to new construction or improvements, the
assessor shall conduct a physical inspection of such property.
11. If a physical inspection is required, pursuant to subsection 10 of this section, the
assessor shall notify the property owner of that fact in writing and shall provide the owner
clear written notice of the owner's rights relating to the physical inspection. If a physical
inspection is required, the property owner may request that an interior inspection be
performed during the physical inspection. The owner shall have no less than thirty days to
notify the assessor of a request for an interior physical inspection.
12. A physical inspection, as required by subsection 10 of this section, shall include,
but not be limited to, an on-site personal observation and review of all exterior portions of the
land and any buildings and improvements to which the inspector has or may reasonably and
lawfully gain external access, and shall include an observation and review of the interior of
any buildings or improvements on the property upon the timely request of the owner pursuant
to subsection 11 of this section. Mere observation of the property via a drive-by inspection or
the like shall not be considered sufficient to constitute a physical inspection as required by
this section.
13. A county or city collector may accept credit cards as proper form of payment of
outstanding property tax or license due. No county or city collector may charge surcharge for
payment by credit card which exceeds the fee or surcharge charged by the credit card bank,
processor, or issuer for its service. A county or city collector may accept payment by
electronic transfers of funds in payment of any tax or license and charge the person making
such payment a fee equal to the fee charged the county by the bank, processor, or issuer of
such electronic payment.
14. [Any county or city not within a county in this state may, by an affirmative vote of
the governing body of such county, opt out of the provisions of this section and sections
137.073, 138.060, and 138.100 as enacted by house bill no. 1150 of the ninety-first general
assembly, second regular session and section 137.073 as modified by house committee
substitute for senate substitute for senate committee substitute for senate bill no. 960, ninety-

sections 137.073, 138.060, and 138.100 as enacted by house bill no. 1150 of the ninety-first
general assembly, second regular session and section 137.073 as modified by house
committee substitute for senate substitute for senate committee substitute for senate bill no.
960, ninety-second general assembly, second regular session, in a year of general
HB 3271 16
reassessment. For the purposes of applying the provisions of this subsection, a political
subdivision contained within two or more counties where at least one of such counties has
opted out and at least one of such counties has not opted out shall calculate a single tax rate as
in effect prior to the enactment of house bill no. 1150 of the ninety-first general assembly,
second regular session. A governing body of a city not within a county or a county that has
opted out under the provisions of this subsection may choose to implement the provisions of
this section and sections 137.073, 138.060, and 138.100 as enacted by house bill no. 1150 of
the ninety-first general assembly, second regular session, and section 137.073 as modified by
house committee substitute for senate substitute for senate committee substitute for senate bill
no. 960, ninety-second general assembly, second regular session, for the next year of general
reassessment, by an affirmative vote of the governing body prior to December thirty-first of
any year.
15. The governing body of any city of the third classification with more than twenty-
six thousand three hundred but fewer than twenty-six thousand seven hundred inhabitants
located in any county that has exercised its authority to opt out under subsection 14 of this
section may levy separate and differing tax rates for real and personal property only if such
city bills and collects its own property taxes or satisfies the entire cost of the billing and
collection of such separate and differing tax rates. Such separate and differing rates shall not
exceed such city's tax rate ceiling] Beginning on January 1, 2027, each county and city not
within a county shall determine the assessed valuation, set and revise rates of levy, and
make adjustments to current levies required under Article X, Section 22 of the
Constitution of Missouri for each subclass of real property, individually, and personal
property, in the aggregate.
[16.] 15. Any portion of real property that is available as reserve for strip, surface, or
coal mining for minerals for purposes of excavation for future use or sale to others that has
not been bonded and permitted under chapter 444 shall be assessed based upon how the real
property is currently being used. Any information provided to a county assessor, state tax
commission, state agency, or political subdivision responsible for the administration of tax
policies shall, in the performance of its duties, make available all books, records, and
information requested, except such books, records, and information as are by law declared
confidential in nature, including individually identifiable information regarding a specific
taxpayer or taxpayer's mine property. For purposes of this subsection, "mine property" shall
mean all real property that is in use or readily available as a reserve for strip, surface, or coal
mining for minerals for purposes of excavation for current or future use or sale to others that
has been bonded and permitted under chapter 444.
