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 generous exemptions too, though those still come with limits. The Missouri retirement income tax now lands lightly on most seniors, but 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 income tests still bite.

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, income-tested 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 | Full only at MO AGI <= $25,000 single / $32,000 joint |
| IRA and 401(k) income | Treated as private pension | Shares the $6,000 exemption | Same income test 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, 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 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 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, and that exemption is income-tested. You qualify for the full $6,000 only if your Missouri adjusted gross income is at or below $25,000 for single filers or $32,000 for married couples filing jointly. Above those levels, the exemption phases down.
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, income-tested $6,000 figure, and most retirees with meaningful account balances will see income above the test thresholds. 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, each with $24,000 in Social Security and $40,000 in additional retirement income. The first draws that $40,000 from a state teacher's pension; under the public pension exemption it falls below the $46,381 cap, so it is fully exempt, and the Social Security is exempt too, leaving little or nothing for Missouri to tax. The second draws the same $40,000 from a traditional IRA; only $6,000 of it can be exempt, and even that shrinks because the income test phases out above $25,000 in Missouri AGI, so most of the $40,000 is taxable. Same headline income, very different Missouri bills. The figures here are hypothetical and shown only to illustrate how the source of income drives the result; they are not a real case and not a prediction of your own outcome.
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
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.
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 and is income-tested. Retirees above $25,000 single or $32,000 joint in Missouri AGI see that exemption reduced.
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.
Yes, and the gap is large. Public pensions get an exemption up to the maximum Social Security benefit, while private pensions get only up to $6,000, income-tested at $25,000 single / $32,000 joint Missouri AGI.
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.
- 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, private pensions only $6,000.
- Treat IRA and 401(k) income as private pension income under the $6,000 income-tested exemption.
- Check your Missouri AGI against $25,000 single / $32,000 joint if you rely on private-pension or account income.
