SCS/SBs 151, 138, 220, 146, 228, & 161 - This act modifies provisions relating to taxation. INDIVIDUAL INCOME TAX 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 the adoption of a constitutional amendment eliminating the income tax, there shall be no individual income tax imposed. (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) CORPORATE INCOME TAX Beginning with the calendar year immediately following the reduction of the state sales tax rate to 4% pursuant to the adoption of a constitutional amendment requiring such reduction, this act provides for the gradual elimination of the corporate income tax. In any fiscal year in which there is a budget surplus of at least $1 million in the General Revenue Fund, the General Assembly shall reduce the rate of corporate income tax by at least 0.2% for each $45 million in the Tax Reform Fund. Such reductions shall continue until the corporate income tax is eliminated. (Section 143.071) STATE SALES TAXES Current law imposes a statewide sales tax at a statutory rate of 4%, with an additional 0.225% rate that is constitutionally authorized, for a total statewide sales tax rate of 4.225%. Beginning with the calendar year immediately following the adoption of a constitutional amendment requiring the reduction of the state sales tax rate, this act provides for the gradual reduction of the state sales tax rate. In the calendar year immediately following the adoption of a constitutional amendment requiring the reduction of the state sales tax rate, this act immediately reduces the state sales tax rate by 0.025%. In any fiscal year following such reduction in which there is a budget surplus of at least $1 million in the General Revenue Fund, the General Assembly shall reduce the rate of sales tax by at least 0.01% for each $45 million in the Tax Reform Fund, and more than one reduction may be made in a fiscal year. Such reductions shall continue until the state sales tax rate is reduced to 4.0% or lower. Once the state sales tax rate reaches 4.0% or lower, the rate shall not exceed 4%. (Section 144.002) This act is substantially similar to SB 138 (2025), SB 161 (2025), SB 220 (2025), SB 228 (2025), SB 458 (2025), and HB 100 (2025). JOSH NORBERG
