Utah Taxpayer Tax Credit
Utah offers a unique taxpayer tax credit that effectively reduces taxes for lower and middle-income earners:
- Credit amount: 6% of the federal standard deduction or itemized deductions
- Phase-out: Credit phases out for higher incomes
- Single filers: Phase-out begins at ~$15,548
- Married filing jointly: Phase-out begins at ~$31,096
The taxpayer tax credit means Utah's effective tax rate is lower than 4.65% for most workers, especially those with moderate incomes.
