What This Bill Does
It changes how personal income tax is calculated for Alabama filers by keeping lower brackets and a top rate that declines each year. For single, head of family, or married filing separately filers, the tax is 2% on the first $500, 4% on income from $500 to $3,000, and 5% on income above $3,000, with the top rate stepping down from 5% in 2022 to 4.95% from 2027 onward. For married filing jointly filers, the tax is 2% on the first $1,000, 4% on income from $1,000 to $6,000, and 5% on income above $6,000, with the same year-by-year reductions to the top rate.

Who It Affects
Single, head of family, or married filing separately filers will see the top rate decline from 5% toward 4.95% by 2027, with bracket thresholds of $500 and $3,000.
Married filing jointly filers will see the top rate decline from 5% toward 4.95% by 2027, with bracket thresholds of $1,000 and $6,000.
