Income tax in Utah

Utah's flat rate for tax year 2025 is 4.50% — House Bill 106 (March 2025) cut it from 4.55%, retroactive to January 1, 2025. Utah has no conventional standard deduction or personal exemption; it instead offers a taxpayer tax credit that phases out with income, which this estimate does not model, so lower earners may owe slightly less than shown.
