Bonus Tax Calculator — Utah (2026)
Bonuses in Utah are taxed as supplemental wages: the employer usually withholds a flat 22% federal, plus 7.65% FICA and Utah state withholding. Withholding is not the final tax; the true cost is settled on your return. Enter your bonus to see both. Utah uses a flat personal income tax of 4.55% applied to taxable income after a state standard deduction of $0.

The gross bonus before withholding.
Percentage method vs aggregate method
Under the percentage method the bonus is separated from regular pay and hit with the flat 22% federal rate (37% above $1 million of supplemental wages in a year). Under the aggregate method the employer combines the bonus with your normal check and withholds at your marginal rate — which can temporarily withhold far more than 22%.
Either way the bonus is ordinary income. If your marginal federal bracket is 24% or higher, the 22% flat withholding leaves you short at filing time; if you are in the 12% bracket, you are over-withheld and get it back as a refund.
The Utah layer on bonuses
Utah taxes bonus income at the same flat rate as salary — up to 4.55%. A $10,000 bonus therefore carries roughly $455 of Utah tax at the top rate, on top of federal and FICA.
Utah has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Reducing the tax on a Salt Lake City bonus
Deferring part of the bonus into a 401(k) or HSA cuts federal and Utah income tax immediately, though FICA still applies. Some employers allow a separate bonus deferral election — ask payroll before the payment date, not after.
Timing matters too: pushing a bonus into January shifts the tax year, useful if this year included unusually high income from tech (Silicon Slopes) work or an equity event.
Local and payroll taxes Utah adds on top
Utah adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Utah has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Bonuses are wages, so every local layer that applies to your regular Utah paycheck applies to the bonus too — which is why a supplemental payment often nets a smaller share than your salary does.
Working across a state line from Utah
Utah has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Salt Lake City resident spending part of the year at a client site in Nevada may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Utah tax bill
Utah charges a 6.1% state sales tax, homeowners pay an average effective property tax of 0.57% of market value, and the minimum wage in force during 2026 is $7.25 an hour.
Combined state and local rates average about 7.25%.
Income tax is only one part of a state's take. Utah recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Utah taxes retirement income at the flat rate but offers a retirement credit that offsets much of the tax on Social Security.
Utah vs Nevada on the same salary
On a $75,000 salary, a single filer keeps about $58,180 a year in Utah against roughly $61,593 in Nevada — a difference of $3,413, or $284 a month.
Effective combined rates are 22.4% in Utah and 17.9% in Nevada. Set that gap against living costs: index 103 here versus 102 there, with property tax at 0.57% and 0.55% respectively.
