This credit phases out at higher incomes.

Social Security & Retirement Taxation
Utah taxes all retirement income but offers a credit for seniors:
| Age 65+ Tax Credit | Maximum Credit |

Bottom Line
Utah has a 4.55% flat income tax — simple and straightforward. The state uses tax credits instead of standard deductions to reduce liability. Utah is not particularly tax-friendly for retirees as it taxes Social Security and retirement income (though seniors 65+ get a credit). Combined with moderate property taxes and sales tax, Utah has a middle-of-the-road tax burden in the Mountain West.
