How Utah treats capital gains

A worked example

Say you are a single filer in Utah with $60,000 of taxable income who sells stock held over a year for a $25,000 long-term gain. Federal tax on the gain is $3,750 (all of it lands in the 15% bracket at this income; no NIIT applies below $200,000 MAGI). Utah adds an estimated $1,125, for a combined $4,875, an effective 19.5% on the gain. These figures use the same math as the calculator, 2026 federal brackets per IRS Rev. Proc. 2025-32, and state figures from the Tax Foundation's State Individual Income Tax Rates and Brackets, 2026.
