How Missouri taxes retirement income in 2026 — Social Security, pensions and IRA distributions — starting from the federal worksheet that decides how much of a benefit is taxable at all, then the state's own subtractions, cliffs and credits, on your figures.
Working income instead? The Missouri paycheck calculator covers wages.
Social Security in Missouri: Not taxed. The federal worksheet runs first — the state only ever sees the federally taxable portion, and most states then exempt it anyway.
From the gross benefit to the state tax, step by step: the federal worksheet, the state's inclusion, the pension subtraction, then the brackets.
| Social Security benefit | $24,000 |
| Federally taxable portion (Pub. 915) | $19,800 |
| Taxed by Missouri | $0 |
| Pension / IRA income | $30,000 |
| Missouri pension subtraction | — |
| Other income | $10,000 |
| Total Missouri tax | $943 |
| of which: the tax on Social Security | $0 |
The default case: $24,000 of Social Security, $30,000 of pension/IRA income, $10,000 of other income, single and 65+. Provisional income is $52,000, so $19,800 of the benefit is federally taxable. Missouri then taxes $0 of that portion, subtracts $0 of pension income, and the total Missouri tax lands at $943.
Now move the age band to 55–64, or push the other income up: the subtractions and thresholds on this page switch exactly where the state’s rules put them, which is where retirement-tax surprises live.
The state's Social Security rule, its pension treatment, and the federal worksheet both stand on.
100% subtraction from TY2024 for taxpayers age 62+ and for Social Security disability benefits at any age, with no income limit (SB 190; RSMo 143.125). Younger survivor benefits are the uncovered edge case.

Public pension exemption up to the maximum Social Security benefit ($48,967 for TY2026 per MO DOR), reduced by any Social Security deduction claimed, with no income limits since 2024 (RSMo 143.124). Private pension exemption: maximum $6,000, only if Missouri AGI is $25,000 or less (single) / $32,000 or less (MFJ). Military retirement is 100% deductible.

Before any state touches your benefits, the IRS decides how much of them is taxable at all: provisional income (your other income plus half the benefit) is tested against $25,000/$34,000 single or $32,000/$44,000 joint, and 0%, up to 50%, or up to 85% of the benefit enters federal AGI. Every figure on this page starts from that worksheet — the calculator runs it for you — and the states that tax Social Security then apply their own subtraction, credit or cliff to the federally taxable portion.

No. Missouri fully exempts Social Security benefits in 2026. The federal tax on benefits still applies; this calculator runs that worksheet too.
On $24,000 of Social Security, $30,000 of pension/IRA income and $10,000 of other income (single, 65+), the federally taxable part of the benefit is $19,800. Missouri taxes $0 of it, subtracts $0 of pension income, and the total state tax is $943. Change any input and the whole chain recomputes.
It depends on provisional income — other income plus half the benefit. Under $25,000 single / $32,000 joint, none of it is taxable; in the middle band, up to 50%; above $34,000 / $44,000, up to 85%. No more than 85% of a benefit is ever taxable federally. The calculator runs the IRS Publication 915 worksheet on your figures.
Public pension exemption up to the maximum Social Security benefit ($48,967 for TY2026 per MO DOR), reduced by any Social Security deduction claimed, with no income limits since 2024 (RSMo 143.124). The calculator applies the subtraction where it is a clean dollar cap and describes the source-specific exemptions (government, military and railroad pensions in several states) rather than guessing your pension’s source.
In several states, yes: subtractions switch on at 55, 60, 62, 65 or full retirement age depending on the state and the provision — Colorado’s pool starts at 55, Georgia’s big exclusion at 65, Iowa’s full exclusion at 55. The age switch on this calculator applies each state’s age tests at band level; exact birthdays matter at the edges, which the page flags.

How Missouri taxes retirement income in 2026: Social Security (not taxed), pension and IRA subtractions, and the federal worksheet underneath — applied to your benefits, your pension and your age.
On the default case — $24,000 of benefits, $30,000 of pension income, $10,000 other income at 65+ — Missouri takes $943, of which $0 falls on the Social Security portion.
The computation order matters and is the order the states use: federal taxable benefits first (Publication 915), then the state’s own inclusion and subtraction rules, then the state brackets through the same verified engine as the paycheck calculators.
No — benefits are fully exempt in 2026.
Because state retirement relief is age-gated: subtractions switch on at 55, 60, 62, 65 or full retirement age. The age band applies each state’s test at band level.
Everything else in AGI — wages, interest, dividends, business income, and capital gains (which stack into the same state base; the capital gains pages price that layer separately).
