Utah Income Tax Calculator 2026
Utah applies a flat individual income tax rate to taxable income, with the same rate applying to all filing statuses. Utah does not provide a separate state standard deduction; instead, federal standard or itemized deductions and a per-dependent personal exemption amount are incorporated into a nonrefundable Utah taxpayer tax credit that may be phased out based on income and filing status. This Utah tax calculator provides a simplified estimate based on the Utah individual income tax structure.
Estimates are shown for the 2026 tax year. In cases where official figures have not yet been finalized, calculations are based on the most recently available data and may be updated when final guidance is published.

Utah Income Tax Calculator 2026 – how it works
Utah individual income tax is calculated by applying a flat 4.55% rate to Utah taxable income. Utah does not use a separate state standard deduction in the same way as the federal return; instead, federal standard or itemized deductions and a per-dependent personal exemption amount of 2,046 are used as inputs to the Utah taxpayer tax credit calculation, which is nonrefundable and may be phased out based on income and filing status. This calculator applies the flat rate structure as a simplified estimate and does not model the taxpayer tax credit phase-out. Official rules and definitions are administered by the Utah State Tax Commission (https://incometax.utah.gov).
Examples
Because Utah uses a flat 4.55% rate, the estimated Utah income tax generally changes in a linear way with Utah taxable income. If taxable income increases, the estimated tax increases by 4.55% of the additional taxable income. In another common scenario, two taxpayers with the same taxable income can have different estimated outcomes because the nonrefundable Utah taxpayer tax credit may vary based on filing status, income thresholds, and the number of qualifying dependents, which affects the personal exemption input amount of 2,046 per dependent.
Limitations and important notes
Results are simplified estimates and may not match a final return. This estimate reflects a flat 4.55% rate and the concept of a 2,046 per-dependent personal exemption amount used within Utah’s taxpayer tax credit structure, but it does not capture every rule that can affect Utah taxable income, credit calculations, credit phase-out thresholds, filing status treatment, or other adjustments under Utah law. Definitions, eligibility conditions, rounding conventions, and interactions between tax components can change the final calculation. For filing and compliance, the official rules, forms, and instructions provided by the Utah State Tax Commission control.
FAQs about Utah Income Tax Calculator 2026
Is Utah a flat tax state?
Yes. Utah applies a single flat individual income tax rate. A flat tax means the same percentage rate applies to Utah taxable income regardless of income level or filing status.
What is Utah’s income tax rate?
Under the current published Utah tax rules, Utah’s individual income tax rate is 4.55% (.0455). Under a flat-rate structure, the same rate applies across filing statuses, and estimated tax generally rises in proportion to taxable income.
Does Utah have a state standard deduction?
Utah does not provide a separate state standard deduction in the same way as the federal return. Instead, federal standard or itemized deductions are used as inputs in Utah’s taxpayer tax credit calculation rather than being subtracted as a separate Utah deduction line.
How does the Utah personal exemption amount work?
Under the current published Utah tax rules, Utah’s personal exemption amount is 2,046 per qualifying dependent and is used as an input to the nonrefundable Utah taxpayer tax credit. Whether and how it applies depends on the filer’s circumstances and Utah’s rules for qualification and credit calculation.
Why might an estimated Utah tax amount differ from a final return?
A simplified estimate may not reflect every rule that affects Utah taxable income or Utah’s taxpayer tax credit. Even with a flat 4.55% rate, the final result can differ due to credit eligibility, credit phase-out thresholds based on income and filing status, adjustments, and detailed definitions in official forms and instructions.
