LLC, DBA or S corp in Utah: which do you need?

Owners mix these three up all the time. They answer three different questions.

• A DBA is a name. It lets you do business under a name that isn't your legal name.
• An LLC or a corporation is a legal entity. It's a separate "person" in the eyes of the law that can own things, sign contracts and owe money.
• An S corp is a tax election. It isn't something you form with the state. It's a choice you make with the IRS about how an LLC or corporation is taxed.

So registering a business in Utah is a sequence: pick the entity, then the name, then later the tax treatment.

Fees checked on Oct 3, 2026

State fees are from the Utah Division of Corporations' current fee schedule. Confirm them before you file.

Option 1: Sole proprietor with a DBA

The simplest setup. If you own an unincorporated business by yourself, you're a sole proprietor and report business income on Schedule C with your personal return.

If you use any name other than your own, register it as a DBA with the state within 30 days of starting to use it. The full steps, the October 2026 law change and renewal rules are in how to file a DBA in Utah.

The tradeoff: a DBA gives no liability protection. You and the business are the same person, so a business debt or lawsuit can reach your personal assets.

Option 2: The LLC

Most small Utah businesses land here. An LLC keeps business debts and claims with the business, and it's cheap to form and run.

Steps to form a Utah LLC:

1. 1Check the name on businessregistration.utah.gov.
2. 2Choose a registered agent with a Utah address. You can usually serve as your own.
3. 3File a certificate of organization online: sign in with UtahID, choose Formations, then the LLC option. The fee is $59. Most online filings are processed right away; ones that need manual review take 5 to 7 business days.
4. 4Write an operating agreement. The state doesn't collect it, but it sets out who owns what and who decides. It matters most with two or more owners.
5. 5Get an EIN free from the IRS. The online application issues the number right away. Never pay a third-party site for one.
6. 6Renew every year. Utah's renewal, now called the annual report, costs $18. It's due by the last day of the month the LLC was formed, and you can file up to 60 days early.

For taxes, an LLC with one owner is treated like a sole proprietor by default, and one with two or more owners like a partnership. It can later choose to be taxed as a corporation or an S corp.

Option 3: How to incorporate in Utah

A corporation adds shares, a board and more record keeping. It fits best if you plan to bring in investors. For most local service businesses, it's more structure than they need.

1. 1File articles of incorporation online at businessregistration.utah.gov. The fee is $59.
2. 2Organize the corporation. Adopt bylaws, name the board, issue shares to the owners and record those decisions in minutes.
3. 3Get an EIN and set up any state tax accounts you need.
4. 4File the annual report each year for $18, by the last day of your anniversary month.

A regular corporation (a C corp) pays income tax on its own profit. When it pays that profit out to owners as dividends, the owners pay tax on it again. The IRS calls this a double tax, and it's the main reason small businesses look at the S corp election.

Option 4: How to start an S corp in Utah

You don't register an S corp with Utah. You form an LLC or a corporation first, then ask the IRS to tax it as an S corporation.

1. 1Check that you qualify. The business must be a domestic corporation or an eligible entity like an LLC, with no more than 100 shareholders and only one class of stock. Shareholders must be individuals, estates or certain trusts and exempt organizations, and none can be nonresident aliens.
2. 2File IRS Form 2553. All shareholders sign it. File by mail or fax; there's no fee for a standard election. An LLC electing S status this way doesn't also need Form 8832.
3. 3Meet the deadline. File no more than 2 months and 15 days after the start of the tax year you want it to apply to, or any time in the year before. For a business on the calendar year, that's March 15. For a brand-new company, the year starts on the earliest of the day it first has owners, assets or business activity.
4. 4Pay working owners a reasonable salary. The IRS requires S corps to pay reasonable compensation to an owner who works in the business before taking other distributions.
5. 5File the returns. Federally, Form 1120-S each year. Utah follows the federal election, so there's no separate state election. An S corporation with a federal election in effect files Utah form TC-20S.

Missed the deadline? The IRS can accept a late election within 3 years and 75 days of the date you wanted it to start, if you had reasonable cause and meet its other conditions.

The election can lower some taxes for a profitable business, but it adds payroll and a separate return. Talk to a CPA before you file Form 2553.

The rest of registering a business in Utah

Whatever you choose, a few steps come after the state filing:

• Federal EIN, free from the IRS.
• State tax accounts with the Utah State Tax Commission if you sell taxable goods or services or hire employees.
• A city business license, or a county license if you're in an unincorporated area. See the guides for St. George and Cedar City.
• A professional license if your trade needs one.

The Utah startup guide puts every step in order with links.

When to talk to a CPA

Bring in a CPA before you elect S corp status, form a corporation instead of an LLC, add a second owner, or start paying yourself or hiring. An hour of advice now usually costs less than unwinding the wrong setup later. For liability questions, talk to an attorney too.

One more thing: Utah reorganized its business entity laws effective October 1, 2026, so section numbers in older guides may be out of date. The annual report timing above comes from the current statute.

After you're registered

Next comes filling the calendar. Some Southern Utah businesses join a local trade network to sell open hours to other member businesses for credits they spend with any member.
