How is a paycheck calculated in Missouri?

Take-home pay in Missouri is gross W-2 wages minus federal income tax (2026 single-filer brackets, $15,750 standard deduction), state income tax (0–4.95% (graduated)), and FICA (Social Security 6.2% capped at $183,600 wage base + Medicare 1.45% on all wages, plus 0.9% additional Medicare above $200K single-filer). The page calculator and reference tables apply this stack at common income tiers.

Does Missouri tax bonuses differently from regular paychecks?

Federal supplemental withholding on bonuses defaults to a flat 22% (or 37% above $1M annual). Missouri state withholding follows the state's supplemental rules: some states use the regular bracket; others use a flat supplemental rate. Year-end your actual tax liability is identical regardless of withholding method — the difference is whether you owe / refund at filing.

How does FICA work on the Missouri paycheck?

FICA = Social Security + Medicare. Social Security is 6.2% of wages up to the 2026 wage base of $183,600 ($10,453 max). Medicare is 1.45% on all wages with no cap. An additional 0.9% Medicare applies to wages above $200,000 for single filers. The FICA stack is identical in all 50 states + DC — Missouri's state-level rules don't change FICA.

Does Missouri have a 'millionaire's tax' or surtax on high earners?

Several states layer surtaxes on top of regular brackets at very high incomes. Massachusetts adds 4% on income above $1M (effective 2023). New Jersey 10.75% top bracket kicks in at $1M. California's 1% mental-health surcharge applies above $1M. Connecticut, New York, and others have considered or implemented similar surtaxes. Missouri's structure is summarized as: 0–4.95% (graduated) — see methodology for surtax details.

What state taxes does Missouri apply to wages?

Missouri's state income tax structure is: 0–4.95% (graduated) . State standard deduction and personal exemption rules differ from federal — see the methodology page for the exact figures applied to the calculator on this page.

Why does my actual Missouri paycheck differ from this calculator?

Common reasons: (1) you're not a single filer (married, head-of-household, MFS — the calculator uses single only); (2) you have pre-tax 401(k), HSA, FSA, or health-plan deductions reducing taxable wages; (3) your local city/county tax applies (calculator excludes those from the headline); (4) you have additional federal/state withholding selected on your W-4; (5) imputed income (group-term life over $50K, etc.) raises taxable wages above your stated salary.

What about HSA, dependent care, or transit benefits in Missouri?

HSA contributions are pre-tax federally and FICA-exempt (one of the few benefits that reduces FICA), and pre-tax in most states except California and New Jersey (which tax HSA at the state level). Dependent Care FSA up to $5,000/year is pre-tax federally and state in most jurisdictions. Transit/parking benefits up to $315/month (2026) are pre-tax federally. The page calculator doesn't model these — apply them as pre-tax adjustments to gross.

TL;DR — Missouri take-home

Missouri's state income tax is progressive (multiple brackets), so the effective rate creeps up with income but stays well below the top marginal until you cross the highest bracket. $100K gross resolves to $75,069.

Cost of living in Missouri runs below the national baseline (BEA RPP 91.1), which lifts the purchasing power of that $75,069 take-home to $82,399 in real terms — a meaningful arbitrage at this income tier.

How Missouri taxes work — 2026 structure

Graduated brackets — effective rate runs below marginal

Missouri uses a graduated (progressive) state income tax: 0–4.95% (graduated). The first dollars of taxable income hit the lowest bracket; only the highest dollars hit the top rate. Your effective state-tax rate is a weighted average of all brackets your income passes through.

At $100K gross, Missouri's effective state rate runs noticeably below the top marginal because most of the income is in lower brackets. At $200K, more income clears the top bracket so effective creeps closer to marginal — visible in the reference table's effective-rate column above.

Real take-home — Missouri cost of living adjusted

Metric	Missouri value
BEA Regional Price Parity (all-items, 2023)	91.1 (US = 100)
RPP — goods	97.3
RPP — rents	70.5
RPP — services	85.6
$100K gross take-home (nominal)	$75,069
Real take-home (purchasing power)	$82,399

Missouri sits below the national cost-of-living baseline (RPP 91.1), so a $75,069 nominal take-home expands to $82,399 in real purchasing power — a meaningful arbitrage at this income tier, particularly visible in rents at 70.5.
