Utah pairs a rock-bottom filing fee with an equally cheap annual renewal, and its flat income tax rate has fallen every year for six years straight. Few states make it this cheap or this fast to get a business on the books and keep it there. Here's what forming one in Utah actually involves in 2026.
1. Which business structure fits you?
Start by sorting out which of these you're actually choosing between:
- Sole proprietorship. Nothing to file, since you and the business are treated as one entity. Straightforward, but you're on the hook personally for anything the business owes.
- Partnership. Multiple owners running the show together, carrying the same personal liability exposure as a sole proprietor, just divided among them.
- LLC. The go-to structure for small Utah businesses, chiefly because it shields your personal assets from the company's debts and lawsuits.
- Corporation, either S-corp or C-corp. Comes with heavier paperwork and formality, generally justified once you bring in investors or multiple shareholders.

LLCs and corporations file with the Utah Division of Corporations and Commercial Code, the state's business-filings agency. Sole proprietorships and general partnerships have no reason to register there.
2. Register your business
Forming an LLC
Forming a Utah LLC means filing a Certificate of Organization with the Division of Corporations. Budget around $54 to $59 depending on the current fee schedule; file online through the OneStop portal and approval frequently comes back the same day. You'll need a free UtahID account before you can file.
Every LLC also needs a registered agent with a physical Utah address who's available during business hours. Serving as your own agent is an option, or you can pay a commercial service instead.
Utah doesn't legally require an operating agreement, but writing one is still a good idea, particularly with more than one member, since it's what governs how decisions and profits get split down the line.
Sole proprietorships and DBAs
There's no Certificate of Organization for sole proprietorships to file. Operating under an assumed name just means registering a DBA directly with the Division of Corporations.
3. Get an EIN
An Employer Identification Number costs nothing through the IRS and takes about 15 minutes to obtain online. You'll need one to open a business bank account, hire anyone, or file most business tax forms, even as a single-member LLC with no employees.
4. Check licenses and permits
There's no single statewide business license covering everything in Utah. What you actually need hinges on your industry and city: certain professions require their own licensing, most cities layer on a local business license, and selling taxable goods or services means getting a sales tax license from the State Tax Commission. Our guides on professional licensing by industry and zoning laws for home businesses go further into both.
5. Understand Utah taxes
Utah runs a flat personal income tax that's declined every single year for six years running, now sitting at 4.45% for 2026. Pass-through LLCs don't owe a separate franchise tax on top of that; elect corporate treatment instead and the corporate income tax rate matches the personal rate at 4.45%, subject to a $100 minimum.
Sales tax opens at a 6.1% combined state and mandatory local base, and additional local option taxes can push the total anywhere from 6.1% up to around 8.85% depending on where the business sits.
6. Stay compliant
Utah LLCs file an Annual Renewal with the Division of Corporations, due by the last day of the LLC's anniversary month each year, for around $18 to $20. Skip the deadline and the state can administratively dissolve the LLC, which then means going through a separate reinstatement process to undo.
