11. a. (1) Any amendment enacted on or after January 1, 2023, with a projected impact that would increase or decrease general fund revenues by greater than $15 million in the fiscal year in which the amendment was enacted or any of the succeeding four fiscal years. The provisions of this subdivision shall not apply to any amendment to federal income tax law that is either subsequently adopted by the General Assembly or a federal tax extender as defined in subdivision b.

(2) All amendments enacted on or after January 1, 2023, and occurring between adjournment sine die of the previous regular session of the General Assembly and the first day of the subsequent regular session of the General Assembly if the cumulative projected impact of such amendments would increase or decrease general fund revenues by greater than $75 million in the fiscal year in which the amendments were enacted or any of the succeeding four fiscal years. The provisions of this subdivision shall not apply to any amendment to federal income tax law that is (i) subsequently adopted by the General Assembly, (ii) a federal tax extender as defined in subdivision b, or (iii) enacted before the date on which the cumulative projected impact is met, or (iv) an amendment to which Virginia does not conform pursuant to subdivision (1). However, any amendment conformed to pursuant to clause (iii) shall be included in the calculation of the $75 million threshold for purposes of determining whether such threshold has been met. Any amendment [ conformed to pursuant to clause (iv) deconformed from pursuant to subdivision (1) ] shall not be included in the calculation of the $75 million threshold for purposes of determining whether such threshold has been met.

(3) Beginning January 1, 2024, the threshold provided by subdivision (1) shall be adjusted annually based on the preceding change in the Chained Consumer Price Index for All Urban Consumers (C-CPI-U), as published by the Bureau of Labor Statistics for the U.S. Department of Labor or any successor index for the previous year.

b. For purposes of this subdivision 11, "amendment" means a single amendment to federal income tax law or a group of such amendments enacted in the same act of Congress that collectively surpass the threshold impact, and "federal tax extender" means an amendment to federal tax law that extends the expiration date of a federal tax provision to which Virginia conforms or has previously conformed.

c. The Secretary of Finance, in consultation with the Chairmen of the Senate Committee on Finance and Appropriations and the House Committees on Appropriations and Finance, shall be responsible for determining whether the criteria of subdivision a are met.

d. The Secretary of Finance shall annually provide a report on or before November 15 of each year on the fiscal impact of amendments to federal income tax law occurring since the adjournment sine die of the preceding regular session of the General Assembly to the Chairmen of the Senate Committee on Finance and Appropriations and the House Committees on Appropriations and Finance. The Secretary of Finance shall also provide updates to the same Chairmen on any further amendments to federal income tax law occurring between submission of the required report and the first day of the subsequent regular session of the General Assembly.

C. The Department of Taxation is hereby authorized to develop procedures or guidelines for implementation of the provisions of this section, which procedures or guidelines shall be exempt from the provisions of the Administrative Process Act (§2.2-4000 et seq.).
