MO SJR115

Constitutional amendment submitted to voters at the November 2026 general election to eliminate Missouri's state individual income tax beginning January 1, 2031, or later, once revenue triggers reduce the top rate below 1.4%

Authorizes the General Assembly to expand the state and local sales and use tax base to cover any goods and services for the purpose of reducing and eliminating the individual income tax

Requires local governments (counties, cities, towns, villages with sales tax rates above 1%, other subdivisions above 0.5%) beginning January 1, 2029, to offset additional revenue from sales tax base expansion by reducing sales tax rates, property tax levies, or earnings tax rates—with no reductions allowed to public school funding

Requires the state auditor by July 1, 2028, to calculate reduced rates for constitutionally-imposed sales and use taxes (except Article XIV) to maintain revenue neutrality based on the median of the three prior fiscal years adjusted for inflation

Exempts tax or revenue increases enacted within three years of the amendment's effective date for income tax elimination purposes from constitutional new revenue requirements under Article X, Sections 18 and 18(e) and Article IV, Sections 30(a)-(d)
