How Bonuses Are Taxed in Utah (2026)
A bonus paid on a separate check in Utah has a flat 22% federal tax withheld (37% on cumulative supplemental wages over $1,000,000 in a year), 7.65% FICA, and Utah's flat 4.45% state income tax. Withholding is not a higher tax rate — it is just how much your employer holds back up front; your actual tax on the bonus is settled when you file, and any over-withholding comes back as refund.
| Component | Rate on the bonus |
|---|---|
| Federal income tax (supplemental, percentage method) | 22% flat · 37% above $1,000,000/yr |
| Social Security | 6.2% (up to $184,500 of total wages) |
| Medicare | 1.45% · +0.9% above $200,000 |
| Utah state tax | 4.45% flat |
Some employers instead use the aggregate method — adding the bonus to your regular paycheck and withholding as if that were every check — which can withhold more or less than the flat 22%. The calculator above uses the flat-rate (percentage) method.

Utah Bonus Tax FAQ
What is Utah's state income tax rate?
Utah charges a flat 4.45% rate for tax year 2026.
How much is take-home pay on $65,000 in Utah?
On a $65,000 gross salary, a single filer in Utah takes home roughly $52,355/year (about $4,362.92/month) after federal tax, FICA, and state tax.
What deductions does Utah apply before taxing my income?
Utah applies a $840 nonrefundable tax credit (subtracted from computed tax, not from taxable income), before the flat 4.45% rate. See the "How Utah Paycheck Tax Is Calculated" section above for the exact formula.
Does this estimate change if I'm married or have dependents?
This calculator uses single-filer figures only (v1 scope). Married filing jointly typically uses different federal and Utah state brackets and a larger standard deduction — your actual take-home pay will differ. Dependents can also reduce federal withholding via the W-4. Check Utah State Tax Commission's married-filing-jointly tables for a precise figure.
Methodology & Source
Utah state tax figures sourced from Utah State Tax Commission (https://tax.utah.gov/), citing SB 60 (2026) — flat 4.45% rate, down from 4.5%. Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Utah's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.
Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled. Utah publishes no separate supplemental withholding rate, so the calculator estimates the state tax on the bonus from your marginal bracket.
This is an estimate based on standard single-filer federal, FICA, and UT state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors. Utah has no standard deduction — instead a $840 nonrefundable personal exemption credit is subtracted directly from computed tax (modeled here), floored at $0.
