Missouri uses a progressive income tax system with rates ranging from 2% to 4.8% for 2026. The standard deduction is $14,200 (single) or $28,400 (married). Most middle-income earners land in the 3.5%–4.8% range, which is moderate compared to neighboring states.

On a $75,000 salary filing single, after the $14,200 standard deduction, your Missouri state tax comes to roughly $2,500–$2,700. Compare that to Illinois at 4.95% flat on the same income ($3,450) and Missouri looks pretty good. But compare it to Tennessee at 0% and the difference is obvious.

On top of Missouri tax, you've got federal progressive brackets with the standard deduction, plus FICA at 7.65% combined. 401(k) contributions reduce taxable income at both the federal and state level. Missouri also allows a deduction for federal income tax paid, which softens the blow somewhat.

Missouri doesn't tax Social Security benefits for most retirees. Property taxes average about 1.01%, and combined sales tax is around 8.33%. Kansas City and St. Louis have additional city earnings taxes of 1%. Compare MO to other states to see where you come out ahead.

How It's Calculated

Formula

MO State Tax = ∑(Bracket Income × Bracket Rate), brackets: 2%–4.8%

Step-by-Step

1Subtract MO standard deduction ($14,200 single / $28,400 married) from gross income
2Apply MO progressive brackets (2%–4.8%) to state taxable income
3Add city earnings tax if applicable (1% in Kansas City and St. Louis)
4Add federal tax (10%–37% progressive brackets) and FICA (7.65%)
5Sum all taxes and subtract from gross pay for net take-home

Example

$75,000 salary, single in MO: MO deduction $14,200. MO tax ≈ $2,600. Federal ≈ $7,670. FICA = $5,738. Net ≈ $58,992.

Missouri Tax Calculator FAQ

How much is Missouri state income tax in 2026?

Missouri uses a progressive income tax system with brackets from 2% to 4.8% as of 2026. The top rate of 4.8% kicks in at relatively low income levels (above $8,099 in taxable income). Missouri has been gradually reducing its top rate in recent years. For a $75K single filer, the effective state tax rate works out to roughly 3.8% after the federal standard deduction is applied.

Does Missouri use federal taxable income?

Yes! Missouri starts with your federal taxable income, which means the federal standard deduction ($16,100 single, $32,200 married) is automatically applied before calculating Missouri tax. This is a significant benefit — your first $16,100 of income is essentially tax-free at the state level too. Some states require you to add back the federal deduction, but Missouri doesn't.

Does Missouri tax Social Security benefits?

Missouri does not tax Social Security benefits. Additionally, Missouri offers a deduction for public pension income up to the amount received from federal or Missouri state retirement plans. Private pension income is largely taxable, though. The state also has a property tax credit (Circuit Breaker) for seniors and disabled individuals.

How does Missouri compare to neighboring states on taxes?

Missouri sits in the middle of the pack regionally. Its top rate of 4.8% is higher than Indiana's flat 3.05% (plus county) and lower than Iowa's top rate. Kansas charges up to 5.7%, Illinois is a flat 4.95%, and Arkansas tops out at 4.4%. Because Missouri uses federal taxable income, the effective rate is often lower than the bracket suggests. Property taxes are moderate at around 0.97%.

Is Missouri a good state for retirees?

Decent but not great. Social Security is exempt, and there's a public pension deduction. But private pensions and 401(k)/IRA withdrawals are still taxed at up to 4.8%. The property tax circuit breaker helps lower-income seniors. If you're comparing to Illinois (which exempts most retirement income) or Tennessee (no income tax at all), Missouri loses for retirees.
