INTRODUCED BY SENATOR GIBBONS.
Read 1st time March 1, 2002, and 1,000 copies ordered printed.
TERRY L. SPIELER, Secretary.
4930S.02I
AN ACT
To repeal sections 137.073, 137.115, 138.060 and 138.100, RSMo, and to enact in lieu thereof four new sections relating to property tax rates, property assessment and procedures for assessment.
Section A. Sections 137.073, 137.115, 138.060 and 138.100, RSMo, are repealed and four new sections enacted in lieu thereof, to be known as sections 137.073, 137.115, 138.060 and 138.100, to read as follows: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, RSMo, 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;
(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, RSMo, 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, RSMo, 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, RSMo, and section 164.013, RSMo, 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] 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 may not exceed the greater of the rate in effect in the 1984 tax year or the most recent voter-approved rate. 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 shall be limited to the actual assessment growth within the political subdivision, exclusive of new construction and improvements, but not to exceed the consumer price index or five percent, whichever is lower.
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, RSMo, 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, RSMo, 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 the 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;
(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 for the three-year period preceding such determination.
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, RSMo, sections 135.200 to 135.255, RSMo, and section 353.110, RSMo, 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.] The assessor shall certify the amount of new construction and improvements 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 June 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 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, RSMo, and section 164.013, RSMo. 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, RSMo, and section 164.013, RSMo, 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 the current tax rate ceiling. The increased tax rate ceiling as approved may be applied to the total assessed valuation of the political subdivision at the setting of the next tax rate.
(3) The governing body of any political subdivision may levy a tax rate lower than its tax rate ceiling [and may], however, once lowered, it shall not increase that lowered tax rate to a level [not] exceeding [the] such lower tax rate ceiling without voter approval.
6. 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/one hundredth] one/ten thousandth of a cent. A taxing authority shall round up a fraction greater than or equal to five/one hundred thousandth of one cent to the next higher [one/one hundredth] one/ten thousandth 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. 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 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.
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 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, RSMo. 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. A taxing authority, including but not limited to a township, county collector, or collector of taxes, responsible for determining and collecting the amount of residential real property tax levied in its jurisdiction, shall report such amount of tax collected by December thirty-first of each year such property is assessed, to the state tax commission. The state tax commission shall compile the tax data by county or taxing jurisdiction and submit a report to the general assembly no later than January thirty-first of the following year.
137.115. 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. Except as otherwise provided in subsection 3 of this section, 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. 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 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 real property in the county owned by the person, or under his or her care, charge or management, and all taxable tangible personal property owned by the person or under his or her care, charge or management, taxable in the county. 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 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. In the event a valuation of subclass (1) real property within any county of the first classification 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) The findings of the assessor based on an appraisal of the property by generally accepted appraisal techniques; and
(2) The purchase prices from sales of at least three comparable properties and the address or location thereof. As used in this paragraph, the word "comparable" means that:
(a) Such sale was closed at a date relevant to the property valuation; and
(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 percents 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;
(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, RSMo, and aircraft which are at least twenty-five years old and which are used solely for noncommercial purposes and are operated less than fifty hours per year or aircraft that are home built from a kit, five percent;
(5) Poultry, twelve percent; and
(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 (6) of section 135.200, RSMo, twenty-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. 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:
(1) For real property in subclass (1), nineteen percent;
(2) For real property in subclass (2), twelve percent; and
(3) For real property in subclass (3), thirty-two percent.
6. Manufactured homes, as defined in section 700.010, RSMo, 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 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. 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. 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 has been converted to real property in compliance with section 700.111, RSMo, 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 has been converted to real property in compliance with section 700.111, RSMo, 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 the trade-in value published in the October issue of the National Automobile Dealers' Association Official Used Car Guide, or its successor publication, as the recommended guide of information for determining the true value of motor vehicles described in such publication. In the absence of a listing for a particular motor vehicle in such publication, the assessor shall use such information or publications which in the assessor's judgment will fairly estimate the true value in money of the motor vehicle.
10. If the assessor increases the assessed valuation of any parcel of subclass (1) real property by more than [seventeen] fifteen percent since the last assessment, excluding increases due to new construction or improvements, then 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 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 for its service.
14. Notwithstanding other provisions of law, any taxpayer of a county, or other political subdivision shall have standing to bring suit in a circuit court of proper venue to enforce the provisions of this section, and, if the suit is sustained, shall receive from the applicable unit of government his or her costs, including reasonable attorneys' fees incurred in maintaining such suit.
138.060. 1. The county board of equalization shall, in a summary way, determine all appeals from the valuation of property made by the assessor, and shall correct and adjust the assessment accordingly. There shall be no presumption that the assessor's valuation is correct. The assessor shall have the burden to prove that the assessor's valuation does not exceed the true market value of the subject property. In the event a physical inspection of the subject property is required by subsection 10 of section 137.115, RSMo, the assessor shall have the burden to establish the manner in which the physical inspection was performed and shall have the burden to prove that the physical inspection was performed in accordance with section 137.115, RSMo. In the event the assessor fails to provide sufficient evidence to establish that the physical inspection was performed in accordance with section 137.115, RSMo, the property owner shall prevail on the appeal as a matter of law. At any hearing before the state tax commission or a court of competent jurisdiction of an appeal of assessment from a first class charter county or a city not within a county, the assessor shall not advocate nor present evidence advocating a valuation higher than that value finally determined by the assessor or the value determined by the board of equalization, whichever is higher, for that assessment period.
2. The county clerk shall keep an accurate record of the proceedings and orders of the board, and the assessor shall correct all erroneous assessments, and the clerk shall adjust the tax book according to the orders of such board and the orders of the state tax commission, except that in adding or deducting such percent to each tract or parcel of real estate as required by such board or state tax commission, he shall add or deduct in each case any fractional sum of less than fifty cents, so that the value of any separate tract shall contain no fractions of a dollar.
138.100. 1. The following rules shall be observed by such county boards of equalization:
(1) They shall raise the valuation of all tracts or parcels of land and all tangible personal property as in their opinion have been returned below their real value; but, after the board has raised the valuation of such property, notice shall be given that said valuation of such property has been increased and a hearing shall be granted; such notice shall be in writing and shall be directed to the owner of the property or the person controlling the same, at his last address as shown by the records in the assessor's office, and shall describe the property and the value thereof as increased; such notice may be by personal service or by mail and if the address of such person or persons is unknown, notice may be given by publication in two newspapers published within the county; such notice shall be served, mailed or published at least five days prior to the date on which said hearing shall be held at which objections, if any, may be made against said increased assessment;
(2) They shall reduce the valuation of such tracts or parcels of land or of any tangible personal property which, in their opinion, has been returned above its true value as compared with the average valuation of all the real and tangible personal property of the county.
2. Such hearings shall end on the last Saturday of July of each year; provided, that the estimated true value of personal property as shown on any itemized personal property return shall not be conclusive on the assessor or prevent the assessor from increasing such valuation. Provided further that said board of equalization shall meet thereafter at least once a month for the purpose of hearing allegations of erroneous assessments, double assessments and clerical errors, and upon satisfactory proof thereof shall correct such errors and certify the same to the county clerk and county collector.
3. The board of equalization in all first class charter counties shall provide the taxpayer with written findings of fact and conclusions of law regarding any parcel of real property which is the subject of a hearing before any board of equalization.
