Utah's PTET election allows pass-through entities to pay the 4.55% flat state tax at the entity level. The entity gets a federal deduction while owners receive a credit on their Utah individual returns.
Section 179 allows businesses to deduct the full purchase price of qualifying equipment, vehicles, and software in the year of purchase rather than depreciating over time. The 2026 federal limit is over $1 million. Some states cap or limit Section 179 conformity — check your state rules.
S-Corp owners must pay themselves a "reasonable salary" subject to payroll taxes (15.3%), but remaining profits distributed as shareholder distributions avoid self-employment tax entirely. Optimizing the salary-to-distribution ratio is one of the most impactful tax strategies for business owners earning $60,000+ in net profit.
A Solo 401(k) allows self-employed individuals with no employees to contribute as both employer and employee — up to ~$69,000/year (plus $7,500 catch-up if 50+). This is typically the most powerful retirement deduction available to self-employed individuals, often exceeding SEP-IRA limits at lower income levels.
The home office deduction (IRC §280A) allows self-employed individuals and business owners to deduct a portion of rent, mortgage interest, utilities, insurance, and repairs based on the percentage of your home used exclusively for business. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 max).
Choosing the right business structure is the single biggest tax decision you'll make. Here's what Utah LLC and S-Corp owners need to know.
Utah LLC Formation
Utah LLCs are taxed as pass-through entities by default. All profits flow to your personal return and are taxed at 4.55% (flat). Electing S-Corp status can significantly reduce your self-employment tax burden.
LLC vs. S-Corp in Utah
Utah offers a Pass-Through Entity Tax (PTET) election — a major advantage for LLC and S-Corp owners. By paying state income tax at the entity level, you bypass the $10,000 federal SALT deduction cap and deduct the full state tax bill on your federal return.
Top LLC Write-Offs in Utah
Utah LLC owners can deduct: business expenses (IRC §162), home office (IRC §280A), vehicle mileage (IRC §179), Section 179 equipment expensing, retirement contributions (Solo 401k or SEP-IRA), health insurance premiums, and business meals. Note: Utah does not conform to federal bonus depreciation — an add-back on your state return may be required.

Yes. Utah offers a pass-through entity tax election that allows S-Corps and partnerships to pay state income tax at the entity level. This is a powerful SALT workaround that lets business owners deduct state taxes on their federal return, bypassing the $10,000 SALT cap. Uncle Kam's tax advisors can help you determine if the Utah PTET election is right for your business.
Utah does not fully conform to federal bonus depreciation rules. You may need to add back bonus depreciation on your Utah state return and depreciate assets over a longer schedule. However, Section 179 expensing may still be available up to Utah's state cap. A tax advisor can help you navigate this.
For most Utah business owners earning over $60,000 in net profit, electing S-Corp status can save $5,000–$20,000 per year in self-employment taxes. The right choice depends on your income level, Utah's franchise or minimum tax requirements, and your business structure.

Self-employed individuals in Utah can reduce state taxes by: maximizing business deductions (home office, vehicle, equipment), contributing to a Solo 401(k) or SEP-IRA, electing S-Corp status to reduce self-employment tax, using the PTET election if available, and timing income and deductions strategically.
