       (2) Notwithstanding the provisions of item (1), the reduction in the top marginal rate contained in this item, as compared to the same in subsection (A), must be phased-in as provided in item (3).  Until the top marginal rate is fully phased-in, the bracket to which this reduced top marginal rate applies must be the same as the bracket for the top marginal rate provided in subsection (A).  All reductions are permanent and cumulative.  During the phase-in and after, the department shall continue to adjust the brackets as provided in Section 12-6-520. Other than the top marginal rate, no other component of this item is phased-in.

       (3) For Tax Year 2022, the top marginal rate shall equal 6.5%.  Beginning with Tax Year 2023, and each year thereafter until the top marginal rate equals 6%, the top marginal rate must decrease by one-tenth of one percent if general fund revenues are projected to increase by at least five percent in the fiscal year that begins during the tax year.  For purposes of this subsection, beginning with the initial forecast required pursuant to Section 11-9-1130, the general fund revenues projection must be determined by the Revenue and Fiscal Affairs Office by comparing the current fiscal year's recurring general fund expenditure base with the Board of Economic Advisors' most recent projection of recurring general fund revenue for the upcoming fiscal year.  Upon the issuance of the initial forecast, the Executive Director of the Revenue and Fiscal Affairs Office, or his designee, shall notify the Department of Revenue of the projected percentage adjustment.  The executive director, or his designee, shall provide similar notice if subsequent modifications to the forecast change the projected percentage adjustment.  However, the forecast in effect on February fifteenth of the current fiscal year is the final forecast for which the percentage adjustment is determined, and no subsequent forecast modifications may have any effect on that determination.  For purposes of this section, "recurring general fund revenue" and "recurring general fund expenditure base" have the same meaning as provided in Section 6-27-30.

    (C) The department may prescribe tax tables consistent with the rates set pursuant to this section. (B)(1) Notwithstanding the provisions of subsection (A), beginning with Tax Year 2027 and each year thereafter, the income tax rate set forth in subsection (A) must be decreased if individual income tax revenues collected pursuant to this chapter, minus amounts credited to the Trust Fund for Tax Relief, are projected to increase by at least five percent in the fiscal year that begins during the tax year


in comparison to projected individual income tax revenues collected pursuant to this chapter, minus amounts credited to the Trust Fund for Tax Relief, for the current fiscal year. The reduction required by this subsection shall continue until the income tax rate equals 2.49 percent. The Board of Economic Advisors shall make the determination regarding income tax projections beginning with the initial forecast required pursuant to Section 11-9-1130.

       (2) If the five percent threshold set forth in item (1) is met, the income tax rate shall be permanently and cumulatively reduced by a percentage that the Board of Economic Advisors projects to result in a reduction in individual income tax revenues collected pursuant to this chapter equal to two hundred million dollars in the fiscal year that begins during the tax year. However, if the five percent threshold set forth in item (1) is met and is not projected to result in increased collections of at least two hundred million dollars in the fiscal year that begins during the tax year, then the reduction is limited to the projected amount of increased collections. Any reduction made pursuant to this subsection must be rounded up to the nearest hundredth of a percent.

       (3) Upon the issuance of the initial forecast, the Executive Director of the Revenue and Fiscal Affairs Office, or his designee, shall notify the Department of Revenue of the projected percentage adjustment. The executive director, or his designee, shall provide similar notice if subsequent modifications to the forecast change the projected percentage adjustment. However, the forecast in effect on February fifteenth of the current fiscal year is the final forecast for which the percentage adjustment is determined, and no subsequent forecast modifications may have any effect on that determination.
