Missouri Retirement Income Tax: A Guide for Seniors (2026)

As of tax year 2024, Missouri stopped taxing Social Security benefits entirely.1 The old income cap is gone, so retirees 62 and older keep 100 percent of their benefits no matter how high their income. Pensions get exemptions too, but the size depends on the type: a public pension gets a large exemption, while a private pension gets only a modest one that is still income-tested. The Missouri retirement income tax now lands lightly on most seniors, though the rules differ sharply between public and private pensions.

This guide breaks down how Social Security, public pensions, private pensions, and IRA or 401(k) income are each treated, and where the sharpest differences fall.

Missouri Retirement Income Tax at a Glance

Missouri treats your retirement income in distinct buckets, and the bucket matters. Social Security is fully out. Public pensions get a large exemption tied to the maximum Social Security benefit. Private pensions, IRAs, and 401(k)s share a much smaller exemption that only lower-income filers get in full.1 The table below lays out each one.

Whatever retirement income falls outside the exemptions above is taxed under Missouri's regular income tax schedule.

Missouri Retirement Income Tax: How It Works

Missouri builds its system around the type of retirement income rather than a single income threshold. The biggest change came for tax year 2024, when the state removed the adjusted-gross-income limit that used to phase out the Social Security deduction.1 The Missouri Department of Revenue confirms that taxpayers 62 and older, or those receiving Social Security disability, now deduct 100 percent of their benefits regardless of income.

Pensions are where the detail lives. Missouri splits them into two tracks. A public pension track, for government retirement systems, carries a large exemption pegged to the maximum Social Security benefit. A private pension track carries a smaller, income-tested exemption that also absorbs IRA and 401(k) withdrawals. Knowing which track your income falls into is the key to estimating what Missouri will tax.

Social Security

Beginning with the 2024 tax year, Missouri no longer taxes the Social Security benefits of taxpayers 62 and older, or Social Security disability benefits at any age.1 The previous AGI-based phase-out was removed, so taxpayers 62 and older (or receiving Social Security disability) deduct the full amount of their benefits from the Social Security Administration no matter how high their other income runs.

This is a clean rule with no income test attached. A retiree with a six-figure pension keeps the same 100 percent Social Security exemption as a retiree living on benefits alone. It is one of the simpler pieces of the Missouri retirement income tax, and one of the most valuable for higher-income seniors who used to lose the deduction.

Public Pensions

Missouri offers a public pension exemption for income from federal, state, or local government retirement systems. The exemption runs up to the maximum Social Security benefit amount: $48,967 for tax year 2026, $47,633 for tax year 2025, and $46,381 for tax year 2024.1 That figure adjusts over time as the maximum benefit changes.

For many retired teachers, state employees, and local government workers, this exemption covers all or nearly all of their pension. If your public pension exceeds the cap, the excess is taxable under Missouri's regular schedule. One catch worth knowing before you count on the full figure: the public pension exemption is reduced by the amount of any Social Security deduction you take.1 The exemption is generous precisely because it is tied to a Social Security figure rather than a flat dollar amount, so it tends to keep pace with benefit growth.

Private Pensions, IRAs, and 401(k)s

Here the rules tighten. Private pensions get a maximum exemption of $6,000 per taxpayer, and unlike the Social Security deduction it kept its income test.1 The full $6,000 is allowed only where Missouri adjusted gross income, reduced by any taxable Social Security benefits, is under $25,000 (single, head of household, or qualifying widow(er)), $32,000 (married filing combined), or $16,000 (married filing separately). That subtraction is easy to miss and it decides cases: a widow with $30,000 of Missouri adjusted gross income, $8,000 of it taxable Social Security, tests at $22,000 and keeps the full $6,000. Above those ceilings the exemption drops by one dollar for every dollar of excess income, so a single filer testing at $31,000 gets nothing.1 It is a per-taxpayer amount, so a married couple who both have private-pension income can each claim their own, subject to that test.

Crucially, IRA and 401(k) distributions are treated under this private pension exemption, not the public one.1 So if your retirement income comes mostly from a 401(k) or traditional IRA rather than a government pension, you are working with the smaller $6,000 figure and the income test that goes with it. For most retirees with meaningful account balances, that means a large share of IRA and 401(k) withdrawals is generally taxable in Missouri.

If you are weighing how much to draw from these accounts to cover care, retirement accounts for care walks through the tradeoffs.

Putting It Together

The practical takeaway is that two retirees with identical total income can owe very different amounts to Missouri depending on the source. A retired state employee whose income is mostly a public pension and Social Security may owe almost nothing. A retiree with the same income drawn from a 401(k) faces the small $6,000 private-pension exemption, may be priced out of it entirely by the income test, and is taxed on most of the rest.1

Picture two single retirees with the same total retirement income. The first draws it from a state teacher's pension; the public pension exemption reaches up to the maximum Social Security benefit ($48,967 for tax year 2026), less any Social Security deduction they take, and the Social Security piece is exempt in its own right, so Missouri taxes a modest share at most. The second draws the same amount from a traditional IRA; at that income level they are well past the $25,000 single-filer ceiling even after the Social Security subtraction, so the $6,000 private-pension exemption has phased out to nothing and the whole withdrawal is taxed under Missouri's regular schedule.1 Same headline income, very different Missouri bills. This example is illustrative, meant only to show how the source of income drives the result, not a prediction of your own outcome.

This guide covers Social Security and public and private pensions. If your income includes military retirement pay or another specialized category, confirm its Missouri treatment with the Missouri Department of Revenue, since separate provisions can apply. This is general information rather than personalized tax advice, and the public-versus-private pension distinction is exactly the kind of detail worth confirming with the Missouri Department of Revenue or a tax professional before you plan withdrawals. If retirement savings are part of how you will fund care, building a senior care funding plan is a useful next step.

Next Steps

If you are retired in Missouri, sort your income by source first. The exemptions are generous for Social Security and public pensions and modest for everything else.1

• Confirm the Social Security exemption applies (age 62+); it carries no income limit for 2024 and later.
• Identify your pension type: public pensions get the large exemption (up to the maximum Social Security benefit, $48,967 for tax year 2026), private pensions only $6,000 per taxpayer.1
• Treat IRA and 401(k) income as private pension income under the $6,000 per-taxpayer exemption, and check your Missouri AGI, less any taxable Social Security, against the $25,000 / $32,000 / $16,000 ceilings before counting on it.1
• Total your remaining taxable retirement income and remember it is taxed under Missouri's regular income tax schedule.
