How Utah income tax works
Utah taxes income at a flat 4.5%, according to the State Tax Commission’s TC-40 instructions; House Bill 106 in 2025 lowered the rate from 4.55% retroactive to the start of 2025, per Tax Foundation. A flat rate does not mean everyone pays 4.5% of their income. Utah gives each filer a nonrefundable taxpayer tax credit instead of a standard deduction: 6% of the federal standard or itemized deduction (excluding the state income tax deduction), phased out at roughly 1.3 cents per dollar of AGI above about $18,200 for single filers and $36,400 for joint filers in Tax Foundation’s 2025 figures. The result is that lower-income households owe little, while higher earners lose the credit.
Utah is one of the few states that taxes Social Security, but it softens the effect. The Commission says Social Security benefits included in federal AGI are taxed, and Utah offers a nonrefundable credit equal to 4.5% of taxable benefits, with a phase-out above $54,000 for single filers and $90,000 for joint filers (the indexed 2026 thresholds are published in the TC-40 instructions). For federal rules, see is Social Security taxable? Utah’s dependent exemption is also set by the state (Tax Foundation lists $2,111 per dependent for 2025), rather than following the suspended federal personal exemption.
Utah’s sales tax structure is unusual: the combined state rate of 6.10% includes a mandatory 1.25% local share, per Tax Foundation, with additional local rates that bring the average to about 7.4%. Property tax is local and primary residences get a 45% exemption on taxable value. Utah’s income tax revenue is constitutionally earmarked for education and certain services for children and people with disabilities, a point that comes up in debates over rate cuts.
