SB 161 - Current law imposes a graduated income tax rate and authorizes reductions in the top rate of income tax contingent on certain state revenue collections, with an eventual top rate of 4.5%. This act provides that, for all tax years beginning on or after January 1, 2026, there shall be a flat income tax rate of 4% on all taxable income. This act also provides for additional reductions in the rate of tax until the income tax is eliminated, provided that a constitutional amendment authorizing such reductions has been adopted. The reductions shall be equal to 0.1% when the balance in the Tax Reform Fund reaches $120 million, with an additional 0.05% reduction for each $60 million in excess of the $120 million minimum balance. (Section 143.011)
Current law also authorizes an income tax deduction for a portion of federal income taxes paid. This act eliminates such deduction beginning with the 2026 tax year. (Section 143.171)
