(7) “Inflation adjusted base year revenues” means the base year general revenue fund collections multiplied by the adjusted consumer price ratio.

(b) Future personal income tax rate reductions. — Beginning on August 15, 2024, and every August 15 thereafter, the Secretary of Revenue will determine whether the total fiscal year adjusted general revenue fund collections from the immediately preceding fiscal year are in excess of the inflation adjusted base year revenues. If the total fiscal year adjusted general revenue fund collections from the immediately preceding fiscal year are in excess of the inflation adjusted base year revenues, then there will be a reduction in the personal income tax rates as determined under this section beginning in the next taxable year.

(c) Determination of rate. — In order to determine the amount of a personal income tax reduction, the excess fiscal year general revenue fund collections will be divided by the amount of the immediately preceding fiscal year’s total personal income tax collections for all funds and will be rounded down to the nearest whole percentage. The amount of the percentage of reduction will be applied equally across the tax rates applicable in the tax year immediately preceding the rate reduction: Provided, That reduction in personal income tax rates may not result in an amount larger than a 10% reduction in the rates set forth in §11-21-4e of this code.

(d) Certification of reduction. – The Secretary of Revenue and the State Auditor will certify to the Tax Commissioner that a rate change is required under this section as soon as possible after August 15 so that the Tax Commissioner may notify taxpayers of any change in personal income tax rates. The certification will provide base year revenues, the total fiscal year general revenue fund collections from the immediately preceding fiscal year, the base year consumer price index, the fiscal year consumer price index, the adjusted consumer price ratio, the amount of inflation adjusted base year revenues, the amount of excess fiscal year general revenue fund collections and the amount of the immediately preceding fiscal year’s total personal income tax collections for all funds.

(e) Applicability of this section. — The provisions of this section shall be applicable in determining the rates of tax imposed by this article and shall apply for all taxable years beginning on and after January 1, 2025, and shall be in lieu of the rates of tax specified in §11-21-4g of this code.

(f) Annual Reports. — The Tax Commissioner shall prepare an annual report to the Joint Committee on Government and Finance detailing any relevant modifications to the personal income tax.
