Utah applies a flat 4.55% state income tax to every taxable dollar. Enter your salary below to see your true net pay after federal, state, and FICA taxes.
Utah is one of a growing number of states that has moved to a single flat income tax rate rather than a tiered bracket system. As of the most recent rate cut, that flat rate sits at 4.55%, applying equally to every dollar of taxable income whether you earn $40,000 or $400,000. This puts Utah in a middle position regionally: Nevada and Wyoming to the west and north charge no income tax at all, Arizona's flat rate is a lower 2.5%, and Colorado sits just below Utah at 4.4%. On the other side, Idaho recently settled on a flat rate of roughly 5.7%, making it more expensive than Utah. Utah does not allow any city, including Salt Lake City, Provo, or Ogden, to levy a separate local income tax, so the flat state rate is the only income tax line you'll see beyond federal withholding. The state does offer several credits — including a taxpayer tax credit and retirement income credit — that can lower your effective rate below the headline 4.55% for many households. Because the rate is flat rather than progressive, your effective and marginal state tax rate in Utah are essentially the same number, which makes it simpler to plug directly into the calculator below alongside your estimated federal and FICA withholding.
