How Missouri bonus withholding works
Short answer: your employer withholds a flat 22% for federal income tax (the supplemental rate), plus 7.65% for Social Security and Medicare, plus Missouri withholding on top: typically 30–35% of a Missouri bonus withheld up front. Bonuses aren't actually taxed at a higher rate, though: at tax time they're ordinary income, and any over-withholding comes back in your refund. Here's how each piece works.
- Federal supplemental rate: Most employers withhold federal income tax from bonuses at a flat 22%, $2,200 on a $10,000 bonus, or 37% above $1 million a year, regardless of your regular bracket.
- Missouri state tax: Bonus income is ultimately taxed through Missouri's graduated income tax (2% to 4.7%). The calculator estimates the Missouri share based on your inputs. Local income taxes in some Missouri cities or counties are not included.
- FICA taxes still apply: Social Security (6.2% up to the annual wage base) and Medicare (1.45%, plus 0.9% for high earners) come out of a bonus like any wage: $765 on $10,000.
- Over-withholding is common: The flat 22% federal rate is often higher than your actual effective rate, and the difference comes back as a refund. In Missouri the whole $10,000 nets $6,565 once state tax and FICA are in.
Your actual bonus tax depends on your total annual income, not the bonus alone: these figures assume a $75,000 Missouri salary. Enter your own numbers above for an estimate that fits your situation.
Frequently Asked Questions
Typically 30–35%: a flat 22% federal supplemental withholding, 7.65% FICA, and Missouri's graduated income tax (2% to 4.7%). Your actual tax owed depends on your full-year income and may be lower: the difference comes back as a refund when you file.
The IRS requires employers to withhold federal income tax from supplemental wages (including bonuses) at a flat 22% rate for amounts up to $1 million, rising to 37% above that. Your employer may alternatively add the bonus to your regular paycheck and withhold using the aggregate method.

It depends on your total annual income and tax bracket. If the 22% flat withholding rate is higher than your actual effective rate on the bonus, you'll get the difference back as a refund; if you're in a higher bracket, you may owe more. On a $75,000 salary in Missouri, a bonus is taxed at about 22% federally plus 4.7% to Missouri, so the 22% flat rate is close to the mark at that income.
Yes: as regular income. Some employers withhold Missouri tax on bonuses at a supplemental rate, but what you ultimately owe is determined by Missouri's graduated income tax (2% to 4.7%) applied to your full-year income. Local income taxes in some Missouri cities or counties are not included.
Splitting a bonus across pay periods can reduce withholding if your employer uses the aggregate method, which annualizes your income, but it changes the timing, not the amount you ultimately owe. Where you live changes the amount: Missouri ranks 26 of 51 on what a $10,000 bonus leaves, against $6,565 in the median state and $6,017 in California.
Against the 8 states Missouri borders, the same a $10,000 bonus is worth $6,565 here: Tennessee keeps $470 more ($7,035), Kentucky keeps $120 more ($6,685), Iowa keeps $90 more ($6,655), Arkansas keeps $80 more ($6,645), Oklahoma keeps $20 more ($6,585), Nebraska keeps $15 more ($6,580), Illinois leaves $25 less ($6,540) and Kansas leaves $88 less ($6,477). Arkansas, Iowa, Kentucky, Nebraska, Oklahoma and Tennessee are the only borders worth crossing for the tax alone.
Missouri has nine brackets (more than most states), which creates complexity, but the top rate is only 4%: lower than many flat-tax states like Illinois (4.95%) or Massachusetts (5.0%). The many brackets mean you move through small increments quickly, but most earners effectively pay close to 4% on most income. A $75,000 earner pays an effective rate very close to 4% (approximately $3,000 annually), while the same earner in Illinois would pay $3,713 (4.95% flat). The real surprise is the sales tax rates, which can reach 10.85% in some areas, completely offsetting the low income tax for big spenders.
