Missouri Voters Say No to Ending State Income Tax

Missouri voters overwhelmingly rejected Amendment 5 on August 4, 2026, with 82.4% voting "no," per Fox 2 St. Louis. At least 1.1 million ballots were cast across 95% of reporting precincts. The measure would have eliminated the state income tax — the tax residents pay on earnings — and changed sales tax rules. Missouri's income tax stays unchanged.
