Reading Utah's bracket structure
Utah's 2025 income tax is a single flat rate of 4.65% applied to taxable income. The flat structure means the effective rate (total tax paid divided by total income) and the marginal rate (tax on the next dollar of income) are identical for every filer earning above the standard deduction. Wage earners can estimate their state tax liability by multiplying taxable income by 4.65%; no bracket-by-bracket calculation is required.
At 4.65%, Utah's top marginal rate is on the lower end of state income taxes — similar to Arizona, Mississippi, North Dakota, and a handful of other states that combine a flat or near-flat structure with relatively low rates. Low-top-rate states typically generate a larger share of total state revenue from sales tax, property tax (via local taxing authorities), or severance tax on natural resources than high-rate states do.
Tax brackets and deduction amounts on this page are the official figures published by the Utah Department of Revenue (or equivalent state tax authority) for the 2025 tax year. They are subject to mid-year revision when the state legislature passes a tax bill, and we update the figures within 30 days of any published change.
