Utah State Tax Compliance: What Businesses Need to Know in 2025
Utah state tax compliance is straightforward relative to most states. Utah uses a single flat income tax rate for both individuals and corporations, runs a simple annual renewal process through the Division of Corporations, and maintains a relatively clean sales tax base. BusAcTa Advisors prepared this guide from official Utah State Tax Commission and Division of Corporations sources to give you a clear 2025 compliance reference for Utah businesses and their owners.
This guide is for general information only and does not constitute tax or legal advice. Consult a qualified tax professional for your specific situation.
Utah Individual Income Tax
Utah imposes a 4.65% flat income tax rate on all individual taxable income for tax year 2024. The same rate applies to the first dollar of income and to the highest earner, unlike the federal graduated system. Utah conforms to many federal income definitions but applies its own additions, subtractions, and credits.
Flat rate: 4.65% for tax year 2024
Return form: TC-40
Due date: April 15 for calendar-year filers
Extension: 6 months to October 15; tax owed must be paid by April 15
Utah Business Income Tax: Pass-Through Entities and Corporations
Utah applies the same 4.65% flat rate to corporate taxable income and to pass-through entity income reported at the owner level.
Entity Type | Utah Form | Rate | Due Date |
|---|---|---|---|
C-Corporation | TC-20 | 4.65% | April 15 |
S-Corporation | TC-20S | Pass-through at 4.65% | March 15 |
Partnership or LLC taxed as partnership | TC-65 | Pass-through at 4.65% | March 15 |
Sample calculation for a Utah S-corporation shareholder:
Share of Utah S-Corp taxable income: $120,000
Utah income tax at 4.65%: $120,000 x 0.0465 = $5,580 owed
Utah requires S-corporations and partnerships to withhold Utah income tax for nonresident owners unless the nonresident files Form TC-40WT (Waiver of Withholding). Composite returns are also available for nonresident owners.
Utah Division of Corporations Annual Renewal
Every Utah entity, including corporations, LLCs, limited partnerships, and registered foreign entities, must file an annual renewal with the Utah Division of Corporations each year. The renewal confirms the registered agent and principal office address.
Annual renewal fee: $18 for most entities
Due date: by the last day of the entity's registration anniversary month
Filing method: online at corporations.utah.gov
Late renewals incur a $10 late fee; failure to renew leads to administrative dissolution
Utah Sales and Use Tax
Utah's state sales and use tax rate is 4.85%. Local jurisdictions, including counties, cities, and transit districts, add additional rates. Combined rates across Utah municipalities range from approximately 6.1% to over 9% depending on location. Most groceries are taxed at a reduced state rate. Prescription drugs and many manufacturing inputs are exempt from sales tax.
Utah Property Tax
Utah has no separate state property tax rate. Property taxes are assessed and collected at the county level. Counties assess real property at 100% of fair market value. Business personal property, including equipment, machinery, and furniture, is also taxable in Utah. Businesses file a personal property declaration with the county assessor by March 1 each year. Failure to file results in an estimated assessment plus a penalty.

Utah Tax Compliance Is One of the Simpler State Systems
Utah's single flat rate for individual and corporate income, a clean annual renewal process at $18, and clearly defined due dates make it one of the more manageable states for compliance. The key dates to track are March 1 for property declarations, March 15 for pass-through entity returns, April 15 for individuals and C-Corps, and the entity's anniversary month for the Division of Corporations renewal.
