Modifies provisions relating to income taxes

This constitutional amendment (SJR 74) would allow Missouri counties to impose their own local income tax if the state's income tax rate falls below 4.5%, provided voters approve the tax at a general election. It directly affects counties and their residents, as counties could add a local tax up to a combined total of 4.5% with the state rate. Key provisions require county voter approval before implementation, mandate that collected funds (minus 1% for collection costs) go to a dedicated "County Income Tax Trust Fund" for the county, and prohibit state control or appropriation of these funds. The amendment must be approved by voters in November 2026 to take effect.
