Utah Income Tax for Business Owners: Flat Rate, Credits and Estimated Payments
Utah Income Tax for Business Owners: Flat Rate, Credits and Estimated Payments
Most Utah business owners want to know two things about state income tax: how much the rate is, and whether they owe money during the year or only at filing time. Utah keeps the answer simple. There is one flat individual rate, a flat corporate rate, and a short list of targeted credits. This guide covers the current numbers, which entity types pay what, and how estimated payments work when no one is withholding for you.
Informational content only. This article is not legal or tax advice. Tax rules change, and your result depends on your entity type, your income, and any other states where you do business. Talk to a qualified CPA or tax attorney before you file, especially if you have an S corporation election, multistate income, or employees.
Utah’s flat income tax rate
Utah taxes individual income at a single flat rate instead of brackets. Under H.B. 106, the rate was 4.5% for 2025. S.B. 60 (2026) lowered it to 4.45% for 2026. That change took effect May 6, 2026, and it applies retroactively to tax years beginning on or after January 1, 2026. The Tax Commission updated withholding for pay periods from June 1, 2026.
S.B. 60 also cut the corporate franchise and income tax rate to 4.45%. The $100 minimum tax did not change.
| Tax year | Individual rate | Corporate franchise and income tax rate | Source |
|---|---|---|---|
| 2025 | 4.5% | 4.5% | H.B. 106 |
| 2026 | 4.45% | 4.45% | S.B. 60 |
| 2027 and later | Check with the Tax Commission | Check with the Tax Commission | S.B. 116 (2026) proposed a revenue-based formula for later years |
Treat the 2027 rate as unsettled. S.B. 116 proposed a revenue-triggered formula, and you should confirm the published rate with the Tax Commission before you budget for next year.
Which Utah tax applies to your entity
Your entity type decides which return carries the income and at what rate. For most small businesses, the answer falls into one of these groups:
- Sole proprietorship or partnership: business income is reported on your individual return and taxed at the individual rate.
- LLC (default treatment): an LLC is taxed by default as a partnership or sole proprietorship. Income passes through to the members and is taxed at the individual rate.
- S corporation shareholders: business income is reported on each shareholder’s individual return at the individual rate.
- LLC that elects corporate treatment, or a C corporation: pays the 4.45% corporate franchise and income tax for 2026, with a $100 minimum tax.
If you are unsure which group you fall into, confirm your federal and state elections with a CPA before you file the first return.
Corporate income tax and the Utah franchise tax question
Many people search for “utah franchise tax” when they mean the corporate tax. Utah’s corporate tax is formally called the corporate franchise and income tax. It applies to corporations and to LLCs that elect corporate treatment.
A standard LLC that does not elect corporate treatment has no separate franchise tax. The only recurring state filing cost for that LLC is the $18 annual renewal. A corporation pays the 4.45% rate for 2026 with the $100 minimum tax, and it files form TC-20 with the Tax Commission. If your corporation or LLC has income from other states, the apportionment rules can change the Utah share, so ask your CPA how your income is allocated.
Utah self employment tax: federal only
Utah has no state self-employment tax. The self-employment tax on net earnings from self-employment is federal only, and you report it with your federal return. Utah does not add a second self-employment charge on top of its flat income tax. A sole proprietor or single-member LLC owner pays the Utah individual rate on the business profit, plus the federal self-employment tax, which is a separate calculation.
Estimated payments when nothing is withheld
Employers withhold Utah income tax from wages. Sole proprietors, partners, LLC members, and S corporation shareholders usually have no withholding on their business profit, so they must pay that tax directly during the year. Waiting until filing time can leave a large balance due.
A practical approach for owners:
- Estimate your net business income after deductible expenses. Start with last year’s return, then adjust for current year-to-date numbers.
- Apply the 4.45% rate for 2026 to the Utah share of that income, and add any other Utah tax you expect to owe.
- Pay in installments during the year through the Tax Commission at tax.utah.gov. This guide does not state Utah’s installment due dates or safe-harbor rules, so confirm them with the Tax Commission before you rely on a schedule.
- Move the money into a separate tax account each time you collect business revenue, so the payment does not come out of operating cash.
Federal estimated payments are a separate obligation with their own rules. Coordinate both with your CPA so you do not overpay one and underpay the other.
Utah credits: targeted, not a general new-business credit
Utah does not offer a general tax credit for starting a new business. Credits are targeted to specific activities, industries, or investments. Before you assume a credit applies, check the Tax Commission’s credit list at tax.utah.gov. Then ask the Governor’s Office of Economic Opportunity (GOEO) about incentives tied to job creation or capital investment. Ask GOEO which conditions apply and when they must be met, because the timing of hiring or spending can matter.
Other Utah business taxes to plan for
Income tax is only one part of the picture. Sales tax is the next most common state obligation for product businesses.
- State sales tax: the state rate is 4.85%, and the state rate on grocery food is 1.75%. Combined state and local rates run from 6.35% to 9.55% depending on the jurisdiction (up to 10.05% in special districts), and the combined grocery food rate is 3.0%. Sellers with an established presence in Utah need a Utah Sales Tax License from the Tax Commission, which you can apply for through TAP.
- Business license: Utah issues no statewide general business license. Registering with the Division of Corporations and Commercial Code is a registration, not a license. Your city or town issues the business license inside its limits, and the county issues it outside them. A city license does not transfer between cities, so a move can mean a new license.
- Occupational license: many professions need a separate license from the Division of Professional Licensing.

When to hire a professional
A single-owner service business with no other states and no employees can often handle the basics on its own. Get professional help if you have an S corporation election, income from several states, employees, a credit you want to claim, or a large expected profit that needs installment planning. A CPA who works with Utah businesses can model the entity choice and the estimated payments before the money is due, which costs far less than fixing a missed payment later.
