Utah currently uses flat income tax rates. Both the individual income tax rate, and the corporate franchise/income tax rates, are 4.55%.

Utah Tax Filing for Corporations & S Corps

If your company is expanding into Utah, understanding the S corp withholding and apportionment rules can prevent underpayment penalties and unexpected tax liability.

  • Filing requirements: Utah recognizes the federal S Corporation election; no separate state S-election filing is required. 
  • A corporation that has elected S status federally files Form TC-20S (Utah S Corporation Return). Prepayment rules and pass-through withholding apply where relevant. Pass-through entities must withhold Utah income tax on Utah-source income for nonresident owners (and certain entity owners). This is generally reported via Schedule N with the TC-20S/TC-65 and flowed through on owners’ Utah returns. Utah also coordinates this withholding with any elective PTE/SALT workarounds as described in state guidance.
  • Allocation & apportionment: Utah uses market-based sourcing for services. It allows either single sales factor or equally weighted three-factor apportionment depending on the taxpayer’s classification. Receipts from services are assigned to Utah if the purchaser receives the greater benefit of the service in Utah (superseding prior cost-of-performance rules).

 

Partnership Tax Filing & Withholding Rules

Filing requirements: Partnerships doing business in Utah (or with Utah-source income/owners) file Form TC-65. They generally remit pass-through withholding on Schedule N for nonresident owners. You must provide a Utah Schedule K-1 so partners can claim the credit for any Utah tax paid on their behalf.

Employees & individual filers

Generally, you must file a Utah individual income tax return if you’re a Utah resident required to file a federal return, or a nonresident/part-year resident with Utah-sourced income. Residents use Form TC-40; nonresidents and part-year residents complete Schedule TC-40B to compute the Utah tax attributable to Utah income.
