Based on 2026 Utah rules and 2026 federal rules, with the standard deduction and no other adjustments. Median income is the 2024 Census figure.

Income tax in Utah

Utah's flat rate for tax year 2026 is 4.45% — Senate Bill 60 cut it from 4.50%, with retrospective operation for taxable years beginning on or after January 1, 2026. 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.
