Utah Tax Calculator

The Utah (UT) Tax Calculator is updated for the 2026/27 tax year. Utah applies a flat state income tax alongside federal income tax, FICA, and Medicare. This calculator estimates your total tax liability and net take-home pay, helping you plan deductions and compare salary offers across Utah counties.

Utah’s simple flat tax system makes it straightforward to estimate state tax, but credits such as the Utah Earned Income Tax Credit and Retirement Tax Credit can still affect your final return. This calculator models these elements in combination with your federal liability.
