Overview
Utah uses a flat state income tax rate and relies on the federal W-4 for withholding purposes. The state only requires the filing status from the federal W-4—no additional state-specific form is needed.
State Income Tax (SIT)
Utah imposes a flat state income tax rate of 4.55% (effective June 2024). The state uses the federal W-4, and only the filing status is needed for the Utah SIT calculation. Per Utah’s Publication 14, no subtraction is made for personal or other withholding allowances claimed on the federal W-4. This makes Utah one of the simplest states for income tax withholding.
| Tax Structure | Flat rate: 4.55% |
| State Withholding Form | Uses federal W-4 (filing status only) |
| No Allowances | Allowances from federal W-4 are not used |
| Supplemental Rate | 4.55% |
| SUTA Rate | 0.3% default for new employers |
Supplemental Wages
Utah supports the following supplemental calculation methods. When using the flat method, the supplemental rate is 4.55%.
Employer State Unemployment Tax (SUTA)
Your assigned SUTA rate will be based on your company’s experience with unemployment claims. New employers typically start at the default rate of 0.3%.
| Tax Type | Employer-paid only |
| Default New Employer Rate | 0.3% |
| Rate Assignment | Experience-rated; assigned annually by the state |
Other Taxes & Obligations
Utah does not currently impose significant additional state-level payroll taxes beyond SIT and SUTA. This keeps payroll relatively streamlined compared to states with multiple layers of tax obligations.
