SECTION 1. (a) Notwithstanding section 1A of chapter 58 of the General Laws or any other general or special law to the contrary, the commissioner of revenue shall further adjust the minimum residential factor of any city or town determined under said section 1A of said chapter 58 for fiscal years 2022, 2023, 2024 and 2025, if adoption of such factor for any such year would result in the residential property class bearing a higher percentage of the total property tax levy than the percentage of the total property tax levy imposed on the residential property class in the prior fiscal year. The new minimum residential factor for such year shall be: (i) for fiscal year 2022, 45 per cent subject to such adjustment upward as may be required to provide that the percentage of the total tax levy imposed on any class of real or personal property shall not exceed 200 per cent of the full and fair cash valuation of the taxable property of the class divided by the full and fair cash valuation of all taxable real and personal property in the city or town; (ii) in fiscal year 2023, 47 per cent subject to such adjustment upward as may be required to provide that the percentage of the total tax levy imposed on any class of real or personal property shall not exceed 197 per cent of the full and fair cash valuation of the taxable property of the class divided by the full and fair cash valuation of all taxable real and personal property in the city or town; (iii) in fiscal year 2024, 49 per cent subject to such adjustment upward as may be required to provide that the percentage of the total tax levy imposed on any class of real or personal property shall not exceed 190 per cent of the full and fair cash valuation of the taxable property of the class divided by the full and fair cash valuation of all taxable real and personal property in the city or town; (iv) in fiscal year 2025, 50 per cent subject to such adjustment upward as may be required to provide that the percentage of the total tax levy imposed on any class of real or personal property shall not exceed 183 per cent of the full and fair cash valuation of the taxable property of that class divided by the full and fair cash valuation of all taxable real and personal property in the city or town; and (v) in fiscal year 2026, 50 per cent subject to such adjustment upward as may be required to provide that the percentage of the total tax levy imposed on any class of real or personal property shall not exceed 175 per cent of the full and fair cash valuation of the taxable property of that class divided by the full and fair cash valuation of all taxable real and personal property in the city or town.

(b) Any city or town which makes use of this section shall include a letter from the commissioner of revenue in each tax bill. The letter shall describe the divergent trends in residential and commercial property valuations, and how the general court has mitigated the negative impact of these trends on residential tax bills with this section.

SECTION 2. (a) The department of revenue, with the assistance of state agencies and political subdivisions that the department deems necessary to complete its charge, shall study the current property tax classification system and to determine sustainable and equitable methods for addressing the current and any future divergence in residential and commercial and industrial property values that result in an abrupt shift of the tax levy onto one class of property taxpayers. The department shall examine ways to provide temporary tax relief to residential ratepayers unable to pay the tax increases resulting from said shifts in the property tax burden, including increasing the residential exemption for people of limited financial means, allowing abatements for the elderly or others who can prove through income tax returns or other documents they do not have the financial resources to pay the tax increases, increasing the income tax deduction for renters, extending the period allowed for payment of property taxes, and other methods of providing targeted tax relief on a temporary basis.

(b) Each city and town for which the commissioner of revenue has determined a minimum residential factor shall provide the department of revenue with the following information on a fiscal year basis: (i) the total tax levy of the city or town; (ii) the percentage of the total tax levy of each of the classes of property by valuation and dollar amount; (iii) the tax rate on each of the classes of property; (iv) the number of outstanding tax delinquencies by property class and the dollar amount of those delinquencies; (v) all agreements relative to payments in lieu of taxes; (vi) all agreements pursuant to chapter 121A of the General Laws; (vii) all tax relief programs offered by the city or town, the efforts used to promote them, the standards for participation, the processes for applying, the number of individuals that applied and the number that were actually accepted into the tax relief program; and (viii) any other information as the department of revenue deems necessary to determine if further changes to the cap are necessary and appropriate.

(c) The department of revenue shall report its findings and any recommendations for legislation to the joint committee on taxation and the clerks of the house of representatives and the senate not later than December 1, 2021.

SECTION 3. The joint committee on revenue shall study and make recommendations for targeted property tax relief to businesses disproportionately impacted by dual tax rates in communities.
