Your business structure is the foundation on which every other financial and legal decision rests. It determines how you’re taxed, how much personal liability protection you have, how you can bring in investors or partners, and what your options are when you eventually want to exit. Choosing correctly the first time saves years of restructuring costs and tax complications.
This guide explains the primary business entity options available in Utah, compares their tax and liability implications, and helps you identify which structure fits your specific situation.

The Four Primary Business Entity Structures
1. Sole Proprietorship
The default structure for a business with one owner who hasn’t taken formal steps to create a separate legal entity. No formation required — you simply start doing business.
Liability: No separation between personal and business assets. A business debt or lawsuit can reach your personal savings, home, and other assets.
Taxation: Schedule C on your personal Form 1040. All net profit subject to self-employment tax (15.3% on the first ~$168,600; 2.9% above). Simplest filing — no separate business return.
Best for: Very early stage, part-time, or side-business operations where liability risk is minimal. Almost all businesses with meaningful revenue should move beyond this structure.
2. Limited Liability Company (LLC)
The most popular business structure in Utah. The LLC provides liability protection (separating personal and business assets) while allowing flexible taxation options.
Formation: File Articles of Organization with the Utah Division of Corporations ($54 filing fee); draft an Operating Agreement (legally optional but practically essential); obtain an EIN. Annual renewal required ($20/year).
Liability: Members (owners) are generally not personally liable for business debts or legal judgments — as long as proper formalities are maintained (separate bank account, no commingling of personal/business funds, operating agreement in place).
Taxation:
- Single-member LLC: disregarded entity; Schedule C on personal return; full SE tax on net profit
- Multi-member LLC: partnership taxation by default; Form 1065 and K-1s; SE tax on general members’ share
- LLC with S-Corp election: FICA only on reasonable salary; distributions avoid SE tax
- LLC with C-Corp election: corporate tax rates; double taxation on dividends
Best for: The vast majority of Utah small businesses — from solo consultants to multi-partner professional firms.
3. S Corporation
An S-Corp is a tax election, not a separate entity type. You first form a corporation or LLC, then elect S-Corp tax treatment with the IRS by filing Form 2553.
Formation: Same as LLC or corporation (Articles of Incorporation for a corporation; Articles of Organization for an LLC). Additional step: Form 2553 S-Corp election, filed by March 15 of the first tax year.
Liability: Same liability protection as an LLC or corporation — personal assets are shielded from business liabilities.
Taxation:
- Files Form 1120-S (corporation) or as an LLC with S-Corp election
- Income passes through to shareholders via Schedule K-1
- Owner-employees pay FICA on reasonable salary only; distributions above salary avoid FICA
- No self-employment tax on K-1 income (key advantage over default LLC)
- Utah Form TC-20S required
Best for: Profitable businesses where the SE tax savings exceed the additional administrative cost — typically when net income is consistently above $60,000–$80,000.
Eligibility restrictions: Maximum 100 shareholders; one class of stock; no non-resident alien shareholders; no corporate or partnership shareholders.
4. C Corporation
A C-Corp is a separate legal entity that pays corporate income tax, with shareholders also taxed on dividends they receive — the “double taxation” structure.
Formation: File Articles of Incorporation with the Utah Division of Corporations; issue shares; elect a board of directors; adopt bylaws.
Liability: Strong liability protection; shareholders are not personally liable for corporate debts.
Taxation:
- Files Form 1120; pays corporate income tax at 21% federal rate
- Shareholders pay personal income tax on dividends received
- Utah corporate income tax: 4.65%
- Effective combined rate on distributed profits can exceed 35–40%
Best for:
- Businesses planning to raise venture capital (VC investors typically require Delaware C-Corp)
- Businesses wanting to offer Incentive Stock Options (ISOs) to employees
- Businesses with high retained earnings that benefit from corporate tax deferral
- Businesses with specific QSBS (Qualified Small Business Stock) tax exclusion planning
Almost never the right choice for: service businesses, professional practices, or any business intending to distribute most profits to owners.

Utah-Specific Entity Considerations
Utah PLLC (Professional LLC)
Licensed professionals in Utah — CPAs, attorneys, physicians, architects, engineers — must form a PLLC (Professional Limited Liability Company) rather than a standard LLC. PLLCs provide the same liability protection and tax flexibility as a standard LLC but are specifically authorized for licensed professional practices under Utah Code § 48-2c.
FJ & Associates is itself a PLLC — the “PLLC” in our name reflects our status as a licensed CPA practice.
Utah Pass-Through Entity Tax (PTET) Election
Utah allows S-Corps and partnerships to elect to pay Utah income tax at the entity level, with a corresponding credit to individual owners. This election may benefit owners whose federal itemized deductions are limited by the $10,000 SALT cap. We analyze PTET eligibility for every pass-through client annually.
Changing Your Entity Structure
Entity restructuring is possible but not free — there are costs in time, filing fees, and potential tax consequences.
- Sole prop to LLC: Simple; file Articles of Organization; transfer assets and contracts
- Single-member LLC to S-Corp election: File Form 2553 by the deadline; begin running payroll
- S-Corp back to LLC (default): Terminating an S-Corp election requires IRS consent if within 5 years of the last election
- LLC to C-Corp: File Form 8832; complex restructuring with potential gain recognition
We analyze the tax consequences of any entity conversion before it’s executed.
