As of tax year 2024, Missouri stopped taxing Social Security benefits entirely. 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. 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 flat exemption. The table below lays out each one.

Income type Treatment Limit or amount Income test
Social Security Fully exempt (62+) 100% of benefits None; cap removed for 2024+
Public pension Exempt up to a cap Up to the maximum Social Security benefit ($46,381 for 2024) Applies above the cap
Private pension Limited exemption Up to $6,000 per taxpayer None; flat per-taxpayer amount
IRA and 401(k) income Treated as private pension Shares the $6,000 exemption None; same as private pensions
Senior-specific exclusion The pension exemptions serve this role See above See above

Missouri's top income tax rate is 4.8 percent for 2024. Whatever retirement income falls outside the exemptions above is taxed under that 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. 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, flat 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 Social Security benefits. 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, which was $46,381 for 2024. 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. 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. It is a flat per-person amount, so a married couple who both have private-pension income can each claim their own $6,000. Any private-pension income above that per-taxpayer figure is taxable under Missouri's regular schedule.

Crucially, IRA and 401(k) distributions are treated under this private pension exemption, not the public one. 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. 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 and is taxed on most of the rest.

Picture two single retirees with the same total retirement income. The first draws it from a state teacher's pension; as long as that pension stays under the public pension cap (up to the maximum Social Security benefit, $46,381 for 2024) it is fully exempt, and the Social Security piece is exempt too, so Missouri taxes little or nothing. The second draws the same amount from a traditional IRA; only $6,000 of it is exempt under the private-pension rule, and the rest is taxed under Missouri's regular schedule. 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.

Frequently Asked Questions

Does Missouri tax Social Security?

No. Beginning with the 2024 tax year, Missouri fully exempts Social Security benefits for taxpayers 62 and older, with no income limit. The old AGI cap that used to phase out the deduction was removed.

Does Missouri tax 401(k) withdrawals?

Generally yes, for most of the amount. 401(k) and IRA income is treated under the private pension exemption, which maxes out at $6,000 per taxpayer. Anything above that per-person figure is taxed under Missouri's regular schedule, so retirees who draw most of their income from these accounts owe tax on the bulk of it.

How much of my public pension is exempt?

Up to the maximum Social Security benefit amount, which was $46,381 for 2024. This covers all or most of many government pensions; any amount above the cap is taxable.

Are private pensions taxed differently than public ones?

Yes, and the gap is large. Public pensions get an exemption up to the maximum Social Security benefit ($46,381 for 2024), while private pensions get only up to $6,000 per taxpayer.

What is Missouri's income tax rate on the income that does get taxed?

Missouri's top income tax rate is 4.8 percent for 2024. Retirement income that falls outside the exemptions is taxed under the regular schedule.

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.
