Utah 2026 Tax Changes
Utah enacted two major tax changes that take effect in 2026: Senate Bill 60 (SB60) reduces the state income tax rate from 4.5% to 4.45%, and House Bill 290 (HB290) expands the state Child Tax Credit by raising the income thresholds at which the credit begins to phase out. Together, these changes reduce state tax liability for most Utah households.
SB60 rate cut
Utah's state income tax rate drops from 4.5% to 4.45%, a 0.05 percentage point reduction applied to all taxable income.
HB290 CTC expansion
Raises the income thresholds at which Utah's Child Tax Credit begins to phase out, expanding eligibility for middle-income families.
Effective 2026
Both changes take effect for tax year 2026, affecting returns filed in early 2027.
Note: SB60 also lowers Utah's corporate franchise and income tax rate from 4.5% to 4.45%. That provision is not included in this analysis, which focuses on household-level impacts.
