Utah charges 4.65% flat state income tax. Use the quarterly tax estimator pre-loaded with Utah rates.
Open Quarterly Tax Estimator →Quarterly estimated payments in Utah must cover both your federal and state obligations. Utah applies a flat 4.65% rate, and most states require their own quarterly payment schedule that may differ from the IRS dates. This estimator pre-loads Utah's tax rates so you can calculate both federal and state quarterly amounts in one place, avoiding underpayment penalties at both levels.
Utah levies a flat 4.65% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 4.65 cents goes to Utah. Utah does not impose local income taxes, so the 4.65% flat rate is the only state-level income tax you owe.
