How Missouri taxes retirement income
Missouri taxes income in 8 brackets for a married couple filing jointly, from 2% to 4.7%; the top rate starts at $9,191 of taxable income[1]. The first $1,313 of taxable income is taxed at 0%. For the example couple below, the last dollar of taxable income falls in the 4.7% bracket.
Before the rate applies, the simulator subtracts a standard deduction of $32,200 on a joint return ($16,100 single), the same amount as the federal standard deduction. It applies no personal exemption.
Social Security benefits are exempt from Missouri income tax: none of the benefit enters the state base, as in 22 of the 24 states covered here that tax income.
The simulator applies no retirement-income exclusion in Missouri: IRA and 401(k) withdrawals and pensions are taxed like other income. Any narrower break in state law that the simulator does not apply is listed under “What this page leaves out”.
Capital gains and qualified dividends are left out of the Missouri base in the simulator.
For single filers the simulator halves the joint deduction and exemption but keeps the joint bracket widths. Where Missouri’s real single brackets are narrower, that understates a single filer’s tax.
Put together, the example couple below owes $1,131 in Missouri, the 14th lowest of the 24 states covered here that tax income.
2026 brackets
| Taxable income over | Up to | Rate |
|---|---|---|
| $0 | $1,313 | 0% |
| $1,313 | $2,626 | 2% |
| $2,626 | $3,939 | 2.5% |
| $3,939 | $5,252 | 3% |
| $5,252 | $6,565 | 3.5% |
| $6,565 | $7,878 | 4% |
| $7,878 | $9,191 | 4.5% |
| $9,191 | and over | 4.7% |
Bracket thresholds are held at these values in every simulated year. The simulator does not index state amounts for inflation.
Worked example
A retired couple, both 67, filing jointly, with $48,000 of Social Security, $40,000 of IRA withdrawals and a $20,000 pension. The figures are computed when the page is built, by the same state-tax function the simulator runs.
| IRA / 401(k) withdrawals + pension | $60,000 |
|---|---|
| Social Security in the state base ($48,000 received, $40,000 federally taxable) | $0 |
| Less retirement exclusion | −$0 |
| Less standard deduction | −$32,200 |
| Less personal exemptions | −$0 |
| Taxable in Missouri | $27,800 |
| Missouri income tax | $1,131 |
| Share of $108,000 gross income | 1.05% |
The couple’s next $1,000 of IRA withdrawals would add $47 of Missouri tax.
A single retiree, 67, with half those amounts ($24,000 of Social Security, $20,000 of IRA withdrawals, a $10,000 pension) owes $477, 0.88% of gross income, against the couple’s 1.05%.
| IRA / 401(k) withdrawals + pension | $30,000 |
|---|---|
| Social Security in the state base ($24,000 received, $11,300 federally taxable) | $0 |
| Less retirement exclusion | −$0 |
| Less standard deduction | −$16,100 |
| Less personal exemptions | −$0 |
| Taxable in Missouri | $13,900 |
| Missouri income tax | $477 |
| Share of $54,000 gross income | 0.88% |
As IRA withdrawals rise
The same couple, with Social Security and the pension unchanged, taking more from their IRAs (a larger withdrawal, a required minimum distribution or a Roth conversion all count as distributions here):
| IRA withdrawals | Missouri tax | Share of gross income | Next $1,000 adds |
|---|---|---|---|
| $0 | $0 | 0.00% | $0 |
| $20,000 | $194 | 0.22% | $45 |
| $40,000 | $1,131 | 1.05% | $47 |
| $80,000 | $3,011 | 2.03% | $47 |
| $120,000 | $4,891 | 2.60% | $47 |
| $200,000 | $8,651 | 3.23% | $47 |
Neighbouring states
The example couple’s state tax in Missouri and in the neighbouring states covered here, same income and ages:
| State | Income tax | Social Security | Couple’s tax | Difference |
|---|---|---|---|---|
| Missouri | 2%–4.7% | Exempt | $1,131 | n/a |
| Illinois | Flat 4.95% | Exempt | $0 | −$1,131 |
| Kentucky | Flat 3.5% | Exempt | $0 | −$1,131 |
| Tennessee | None | Not taxed | $0 | −$1,131 |
Against Missouri, the couple would pay less in Illinois (−$1,131), Kentucky (−$1,131), Tennessee (−$1,131). With $200,000 of IRA withdrawals instead of $40,000, they would owe $8,651 in Missouri, against Illinois ($0), Kentucky ($5,287), Tennessee ($0).
What this page leaves out
What the simulator does and does not handle for Missouri, item by item[1]:
- 2025 married filing jointly schedule (0%–4.7%).
- Federal-conformity standard deduction (derived from the federal figure, $32,200 married filing jointly for 2026).
- Social Security fully exempt (SB 190).
- No general retirement exclusion (means-tested private-pension exemption ignored).
- Capital gains 100% deductible from 2025 (HB 594), so preferential income excluded, which also drops qualified dividends MO actually taxes (slight understatement).
In every state the simulator also leaves out credits, itemized deductions, deductions that phase out with income, local income taxes, surtaxes and any deduction for federal tax paid. It holds state amounts fixed and does not index them for inflation.
