Missouri Voters Reject 2026 Ballot Measure to Eliminate State Income Tax
On August 4, 2026, Missouri voters turned down Amendment 5, a proposal to phase out the state personal income tax and replace it with a broader sales tax.
Missouri's August 4, 2026 ballot featured Amendment 5, a constitutional amendment drafted by the state legislature to gradually abolish the personal income tax and fund the shortfall with a broader, higher sales tax. Proponents argued the change would simplify taxation and boost economic competitiveness. However, voters expressed reluctance to adopt an untested revenue model and ultimately rejected the measure. The outcome preserves the current income tax system and maintains the state's existing revenue sources. Analysts suggest the decision reflects voter caution toward sweeping fiscal reforms.
Why it matters
The vote keeps Missouri's tax structure unchanged, affecting state revenue and taxpayers.
