Missouri taxes at a glance (2026)

Missouri has a graduated income tax with a standard deduction of $16,100 (single) / $32,200 (married). Graduated 8-bracket schedule, top rate 4.7% (confirmed against official 2026 MO DOR Withholding Formula as reproduced in the USDA/NFC 2026 bulletin, effective pay period 08/2026). Brackets apply to MISSOURI TAXABLE INCOME (after the standard deduction); thresholds are IDENTICAL for all filing statuses - only the standard deduction differs by status (Single/MFS/Married-spouse-works $16,100; Married-spouse-does-not-work/MFJ $32,200; Head of Household $24,150), tied to the federal standard deduction. NOTE: 2025 figures used $1,313 increments with the top rate over $9,191 - the 2026 schedule uses $1,348 increments with the top rate over $9,436; do not confuse the two. The 4.7% top rate was reached via SB 3 (2022) revenue triggers effective Jan 1, 2025; further 0.1pt cuts toward 4.5% possible if revenue triggers are met. HB 798 (2025 session) would have converted MO to a FLAT 4.7% rate with a standard deduction $4,000 above federal starting TY2026, but it was NOT enacted, so the graduated schedule above remains current law. Effective 2026, Missouri NO LONGER allows subtraction of federal income tax withheld. Social Security benefits are 100% exempt (full exemption phased in, complete since TY2024). Public/private pension and military retirement exclusions available. 100% of capital gains reported federally may be subtracted from Missouri AGI (effective TY2025). Local earnings taxes: Kansas City and St. Louis each levy a 1% earnings tax on wages of residents and on wages earned within the city by nonresidents (separate from state tax).
