Utah State Income Tax Withholding
Last Updated: January 2026
Overview
Utah uses a flat tax system for individual income tax. The rate was reduced from 4.55% to 4.5% effective June 2025, making Utah one of the more tax-friendly states with an income tax.
2026 Tax Rate
| Income Type | Tax Rate |
|---|---|
| All taxable income | 4.50% |
Recent Change: Rate reduced from 4.55% to 4.50% effective June 2025.
Deductions and Exemptions
Utah calculates tax differently than most states:
Taxpayer Tax Credit
Instead of standard deductions, Utah provides a taxpayer tax credit that effectively creates a 0% bracket for lower incomes:
- Single/Married Filing Separately: 6% of (federal standard deduction + exemptions)
- Married Filing Jointly: 6% of (federal standard deduction + exemptions)
This credit phases out at higher income levels.
Personal Exemption
Utah uses the federal personal exemption amount (currently suspended federally but Utah maintains its own calculation).
Supplemental Wage Rate
- Supplemental wages: 4.50% (flat rate)
Special Considerations
- Form W-4: Utah accepts the federal Form W-4 for state withholding purposes
- No State-Specific Form: Unlike many states, Utah does not require a separate state withholding form
- No Local Income Taxes: Utah municipalities do not levy local income taxes
- Social Security Exemption: Social Security benefits are exempt from Utah income tax
Withholding Calculation
Utah withholding is calculated using:
- Federal Form W-4 information
- Utah withholding tables (Publication 14)
- The flat 4.50% rate
- Taxpayer tax credit adjustments
Military and Retirement
- Military Retirement: Partial exemption available for military retirement pay
- Retirement Income: Utah taxes most retirement income but offers credits for seniors
