2026 · Self-employed tax guide
If you freelance, contract, or run a one-person business in Utah, taxes work differently than they did on a W-2. Here's what you actually owe in 2026 — and how much to set aside so a bill never catches you off guard.
Utah taxes personal income at a flat 4.5%. Whether you net $30,000 or $130,000 from self-employment, the same state rate applies to your taxable income.
The biggest shock when you go independent isn't income tax — it's self-employment tax. On a W-2, your employer quietly paid half of your Social Security and Medicare. On your own, you pay both halves: 15.3% of your net earnings, on top of any federal and state income tax. This is the same in every state, and it's why setting money aside matters so much.
You'll generally make quarterly estimated payments to both the IRS and Utah — miss the deadlines and you can owe penalties even if you settle up at year-end. A good rule of thumb is to move a fixed percentage of every payment into a separate account the moment it lands.
The 2026 federal quarterly due dates are April 15, June 15, September 15, 2026, and January 15, 2027.
