Utah Paycheck Calculator

Utah's flat income tax rate has fallen every year for six consecutive years through 2026, the latest reduction coming via Senate Bill 60, which cut the rate from 4.50% to 4.45% and was signed by Governor Spencer Cox, effective retroactively to January 1, 2026. EY's professional tax-news coverage of the Utah State Tax Commission's revised withholding formula confirms this figure directly.

Interestingly, Tax Foundation's most recently retrieved 2026 table still showed 4.50% at the time of this calculator's research — evidently not yet updated to reflect SB60's mid-cycle change — so this calculator uses the more current primary-source Utah Tax Commission figure (via EY's coverage) rather than the slower-to-update secondary source, a genuine judgment call about which source is more current rather than which is generally more authoritative.

Each of Utah's six consecutive cuts has required its own separate legislation, not an automatic formula, so whether a seventh cut happens for 2027 depends on future legislative action this calculator does not attempt to predict.

Utah doesn't use a traditional standard deduction the way most states on this site do. Instead, Utah Code §59-10-1018 establishes a nonrefundable Taxpayer Tax Credit, calculated as 6% of the sum of a filer's federal standard (or itemized) deduction plus Utah's per-dependent personal exemption, then phased out at a rate of 1.3 cents per dollar of income above a filing-status-specific threshold — $18,213 single/MFS, $36,426 married filing jointly, or $27,320 head of household, per the most recently confirmed figures at the time of this calculator's research.

The crucial distinction: this is a CREDIT, subtracted dollar-for-dollar from tax owed, not a DEDUCTION subtracted from taxable income before the rate is applied. This engine's StateTax shape has a standardDeduction field built for the deduction mechanism, with no way to represent a post-tax credit without mischaracterizing how it actually works — and the credit's income-based phase-out means even repurposing that field couldn't substitute a single constant figure for every income level.

This calculator therefore computes Utah tax as a pure 4.45% flat rate on full gross wages and explicitly does not include the Taxpayer Tax Credit. For a single filer with no dependents, that credit is worth up to $966 at low incomes (6% of the $16,100 federal standard deduction), phasing to $0 by roughly $92,500 of income — a genuinely material omission at moderate incomes that this guide states plainly rather than letting the calculator's number pass as exact liability.

This calculator's Utah figures cover federal income tax, Utah's flat state income tax (before the Taxpayer Tax Credit described above), and the two federal FICA taxes. Utah has no state-run disability insurance or paid-family-leave payroll premium as of 2026, unlike states such as Colorado, Minnesota, or Connecticut that layer a genuine second payroll deduction on top of income tax.

Utah does not levy local city or county income taxes on top of the state rate, so aside from the Taxpayer Tax Credit gap described above, this calculator's stateTax figure represents a reasonably complete before-credit picture of Utah state income tax.

A Utah filer with income below roughly $92,500 (single) should treat this calculator's stateTax and totalTax figures as genuine overstatements of their real tax liability, since the Taxpayer Tax Credit would meaningfully reduce their actual Utah tax owed below what this calculator shows.
