CORRECTION (NOVEMBER 1, 2026): An earlier version of this October 30 article incorrectly stated that Missouri voters would decide Amendment 5 on November 3. Amendment 5 was on the August 4, 2026 primary ballot and was defeated. We regret the error.

JEFFERSON CITY, Mo. — Missouri voters overwhelmingly rejected Amendment 5 at the August 4 election. Official returns showed about 83.3 percent voting no and 16.7 percent voting yes.

The proposal would have established an approach to phasing out Missouri's individual income tax while allowing other tax changes, including expanded state sales and use taxes. Those changes were not enacted through the defeated measure.

Amendment 5 is not on the November 3 ballot. Readers should consult the Secretary of State's election information for a complete current ballot list.
