Utah uses a flat state income tax of 4.5% in 2026 — the same rate applies to every dollar of taxable income, which makes your paycheck easy to predict. On a $75,000 salary, a single filer pays about $3,413 in state tax and takes home roughly $58,180 a year (about 77.6% of gross) after federal, state, and FICA withholding.

Utah's 4.5% rate is below the 4.8% average among states that tax wage income. Because the rate is flat, a raise never pushes part of your income into a higher state bracket — every extra dollar is taxed at the same 4.5%, unlike the federal system where higher earnings hit progressively higher brackets.

Remember that FICA is separate from income tax and is not affected by your state. Every worker pays 6.2% for Social Security on the first $184,500 of wages (the 2026 wage base) plus 1.45% for Medicare on all wages. Pre-tax 401(k) and HSA contributions lower your federal and state income tax but do not reduce FICA — a detail that trips up a lot of first-time budgeters.

Utah's flat tax has been nudged downward several times in recent sessions as the state's young, fast-growing economy produced repeated surpluses. A quirk worth knowing: Utah implements its standard deduction and exemptions as credits that phase out at higher incomes, so high earners face a slightly higher effective rate than the flat rate implies. The Silicon Slopes tech corridor has brought coastal salaries to a still-below-coastal cost of living.
