How Utah 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 Utah's flat 4.5% income tax: about 34.2% of a Utah 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. Utah is not alone: Oklahoma leave exactly the same $6,585.

  • 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.
  • Utah flat tax: Utah taxes bonuses like all other wages at its flat 4.5% rate: there's no separate state bonus rate.
  • 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 Utah the whole $10,000 nets $6,585 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 Utah salary. Enter your own numbers above for an estimate that fits your situation.

Frequently Asked Questions

Typically about 34.2%: a flat 22% federal supplemental withholding, 4.5% Utah income tax, and 7.65% FICA. Your actual tax owed depends on your full-year income and may be lower: the difference comes back as a refund when you file.

It depends on your total annual income and tax bracket.

On a $75,000 salary in Utah, a bonus is taxed at about 22% federally plus 4.5% to Utah, so the 22% flat rate is close to the mark at that income.

Yes: as regular income. Utah taxes all wage income, including bonuses, at its flat 4.5% rate; there is no separate state bonus rate.

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: Utah ranks 23 of 51 on what a $10,000 bonus leaves, against $6,565 in the median state and $6,017 in California.

Against the 6 states Utah borders, the same a $10,000 bonus is worth $6,585 here: Nevada keeps $450 more ($7,035), Wyoming keeps $450 more ($7,035), Arizona keeps $200 more ($6,785), New Mexico leaves $25 less ($6,560), Colorado leaves $34 less ($6,551) and Idaho leaves $80 less ($6,505).

Utah's flat 4.5% rate is identical to Colorado's, but Utah doesn't have the same local sales tax variations. This creates a more predictable tax burden, but the 4.5% rate is higher than neighboring states like Wyoming (no income tax) or Nevada (no income tax), which surprises people who assume all Western states have similar tax structures. A $75,000 earner pays $3,375 annually in Utah, while the same earner in Wyoming or Nevada pays $0.
