Missouri Paycheck Calculator Updated Edition
Missouri’s tax brackets look like they belong to a different decade — eight rate tiers packed into less than $9,500 of income, each one barely $1,348 wide. In practice, that means almost every working Missourian lands in the top 4.70% bracket within the first paycheck or two of the year. But Missouri also offers something genuinely rare: a 100% exemption on capital gains, a feature more generous than almost any other state. This calculator uses the Missouri Department of Revenue’s official 2026 withholding formula to get both sides right.

Missouri’s Eight Brackets Squeeze Into Less Than $9,500 — Here’s Why That Matters
Most progressive tax systems spread their brackets across a wide income range, so a meaningful raise might genuinely move you into a new tier. Missouri does something different. Its eight tax brackets — 0%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, and a top rate of 4.7% — are all packed into the first $9,436 of taxable income, with each bracket spanning a narrow $1,348 band. Once your taxable income clears that threshold, every additional dollar is taxed at the flat 4.7% top rate for the rest of the year. In practical terms, Missouri behaves almost exactly like a flat-tax state for anyone earning a typical full-time salary — the eight-bracket structure mostly only matters for the first slice of income, not the bulk of what you actually take home.
How the Compressed Brackets Actually Work
Under the Missouri Department of Revenue’s 2026 withholding formula, taxable income climbs through each bracket in lockstep: $0 to $1,348 is tax-free, then $1,348.01 to $2,696 is taxed at 2%, climbing through 2.5%, 3%, 3.5%, 4%, and 4.5% in matching $1,348 increments, before everything above $9,436 hits the 4.7% ceiling. For a married filer earning $35,000 with the standard $16,100 deduction, that works out to roughly $707 in annual Missouri tax on $18,900 of taxable income — and the official DOR worksheet confirms this exact math, since most of that taxable income sits well above the $9,436 threshold and gets taxed at the flat 4.7% rate.
The Capital Gains Exemption Most Calculators Miss Entirely
Here’s the genuinely standout feature of Missouri’s tax code, and one that almost no online paycheck calculator accounts for: starting with the 2025 tax year, Missouri allows taxpayers to subtract 100% of the capital gains reported on their federal return when calculating Missouri taxable income. Not 25%, not 50% — the entire amount. That puts Missouri in rare company nationally; compare this to Arizona’s 25% long-term capital gains subtraction, and Missouri’s benefit is four times more generous. If you have investment income on top of a regular paycheck, this is the single most valuable Missouri-specific detail to understand, and it’s exactly why this calculator includes a dedicated field for it rather than burying it in fine print.
A Possible Future Without Any Missouri Income Tax
Missouri voters will decide a constitutional amendment on August 4, 2026, that would gradually reduce and eventually eliminate the state’s individual income tax, replacing the lost revenue with an expanded sales and use tax base. Supporters argue it would make Missouri more competitive with neighboring no-tax and low-tax states and let workers keep more of each paycheck from the start. Opponents argue the swap shifts the tax burden toward middle- and lower-income households who spend a larger share of their income on taxable purchases, and warn it could squeeze funding for public services over time. The amendment wouldn’t eliminate the income tax overnight — it ties future rate cuts to revenue growth — so for the 2026 tax year, the brackets covered in this calculator remain in effect regardless of the outcome. It’s worth watching if you’re planning Missouri finances multiple years out.
- Military retirement pay is fully exempt — Missouri excludes 100% of military retirement income from state tax, separate from the broader treatment of other pensions.
- Federal tax is partially deductible — Missouri allows a deduction tied to a percentage of your federal tax liability, scaled to your Missouri adjusted gross income, though the benefit is smaller than Alabama’s full federal-tax deduction.
- Seniors get an extra deduction — married couples filing jointly where one or both spouses are 65 or older, or blind, receive an additional $1,600 standard deduction on top of the regular amount.
- A property tax credit exists for qualifying seniors — renters can claim up to $750 and homeowners up to $1,100 toward real estate taxes or rent paid, based on total household income.
Federal Tax and FICA Still Apply the Same Way
None of Missouri’s bracket compression or capital gains treatment changes what happens federally. Social Security is withheld at 6.2% up to the annual wage base, Medicare at 1.45% on every dollar, with an additional 0.9% surtax once your wages clear $200,000 single or $250,000 married filing jointly. Federal income tax still runs through the standard progressive brackets from 10% up to 37%. Missouri’s state-level math only changes what happens after that federal layer — and for most wage earners, it adds up to a flat 4.7% on the bulk of their income.
| Deduction | Rate | Applies To |
|---|---|---|
| Federal Income Tax | 10%–37% | Taxable income after deductions |
| Missouri State Income Tax | 0%–4.7% (8 brackets) | Taxable income after standard deduction; top rate starts at $9,436 |
| Missouri Tax on Capital Gains | 0% | 100% subtraction on qualifying capital gains, starting TY2025 |
| Social Security | 6.2% | Wages up to the current annual wage base |
| Medicare | 1.45% | All earned income |
| Additional Medicare Tax | 0.9% | Income above $200,000 (single) / $250,000 (married) |
Frequently Asked Questions
What are Missouri’s state income tax rates?
Missouri uses eight compressed brackets ranging from 0% to 4.7%, all packed into the first $9,436 of taxable income. Because the brackets are so narrow, most working Missourians end up paying close to the top 4.7% rate on the bulk of their income.
Does Missouri tax capital gains?
No, starting with the 2025 tax year. Missouri allows a 100% subtraction of capital gains reported on the federal return when calculating Missouri taxable income, making it one of the most favorable states in the country for investment income.
What is Missouri’s standard deduction for 2026?
For 2026, Missouri’s standard deduction matches the federal amount: $16,100 for single filers, married filing separately, and married filing jointly with both spouses working; $32,200 for married filing jointly with one spouse not working; and $24,150 for head of household.
Could Missouri eliminate its income tax?
Possibly, over time. Missouri voters decide a constitutional amendment on August 4, 2026, that would gradually reduce and eventually eliminate the state income tax, funded by an expanded sales tax base. Any changes would phase in gradually based on revenue growth, not take effect immediately.
Is military retirement pay taxed in Missouri?
No. Missouri fully exempts military retirement pensions from state income tax, separate from the more limited treatment given to other types of pension income.
How does a 401(k) affect my Missouri paycheck?
Pre-tax 401(k) contributions lower your taxable income for both federal tax and Missouri state tax at the same time, since Missouri’s brackets apply to the same reduced taxable income base used for the federal calculation.
How accurate is this Missouri paycheck calculator?
