Income Tax in Utah
Utah (UT) has a flat income tax rate of 4.7% for tax year 2025. The standard deduction is $0 for single filers and $0 for married filing jointly.
Utah runs a low-rate income tax. The top marginal bracket sits in the bottom band of the U.S. state-tax distribution, and the effective rate paid by typical households is correspondingly modest. State revenue mixes income tax with sales and property taxes.
For households comparing Utah against other states, the full picture combines income tax (modeled by the calculator) with state and local sales tax, property tax, and any state-specific tax preferences. The compare tool on this site runs a side-by-side total-burden estimate; the per-state pages cover the income-tax piece in detail.
TaxCompare answers state and federal tax questions using the IRS Revenue Procedures and the Tax Foundation state-tax database — the authoritative current-year statutory sources. Every numeric answer on the site uses current-year brackets, deductions, and rates as published by those sources.
Two things to know. First, statutory rates and effective rates are different. A 6 percent state with deductions and credits can produce a lower effective tax than a 4 percent state with no deductions. The compare tool runs effective-rate calculations. Second, multi-state filers (work in one state, live in another) have residency rules the tool does not currently model; the output reflects single-state residence.
How Utah Income Tax Works
Utah uses a flat-rate income tax structure for tax year 2025: a single rate of 4.7% applies to taxable income above the standard or itemized deduction. Flat-rate states do not stack marginal brackets — every taxable dollar is taxed at the same rate, which simplifies returns at the cost of less progressivity than a bracketed structure.
Utah does not provide a state-level standard deduction in the way most states do. Some states instead use personal exemptions, exemption credits, or conformity to the federal taxable-income figure. Check the state revenue department's instructions for Utah for the specific mechanism that applies to your filing status.
Compared to states with progressive brackets, Utah's flat structure means a household earning twice as much pays roughly twice as much in state tax (after the standard deduction). High earners pay less than they would under most progressive schedules; low earners typically pay more.

What This Page Cannot Tell You
The brackets and deductions above describe the statutory state-level rules. Your actual state tax liability depends on credits (earned-income credit, child credit, dependent credit), itemized deductions, retirement-income exclusions, local-government taxes (city or county income tax in some states), and federal taxable-income conformity rules. None of those interactions are computed here.
