Utah

Corporate income tax

Corporate franchise or income tax return (Form TC-20) is due on or before the 15th day of the fourth month following the close of the tax year, or the due date of the federal return, whichever is later; next business day if it falls on a Saturday, Sunday or legal holiday. Rate 4.5% for 2025 tax years (lowered from 4.55% by 2025 HB 106). Minimum tax (privilege tax) $100 for every corporation filing TC-20.

Extension. Automatic extension of up to six months to file (calendar-year: Oct 15) with no extension form required

Partnerships and S corporations

Pass-through entities must withhold Utah tax (Schedule N) for nonresident individual and business-entity owners unless a waiver applies; withholding is payable by the original due date regardless of extension. SALT workaround (2022 HB 444): a partnership, S corporation or trust (not a disregarded entity) may elect to pay Utah 'SALT tax' on voluntary taxable income at the individual income tax rate (4.5% for 2025) on behalf of final pass-through entity taxpayers. The election is made by electronically filing the TC-75 SALT Report and paying electronically through TAP on or before the last day of the PTE's taxable year (Dec 31 for calendar-year entities); payments after that date are refunded and do not qualify. Owners claim the Pass-through Entity Taxpayer credit (credit AP); 2025 HB 60 extended its carryforward from 5 to 10 years.

Sales and use tax

Due date. Returns and payments are due the last day of the month following the end of the filing period (quarterly: April 30, July 31, October 31, January 31; monthly: last day of the following month). If the due date falls on a weekend or holiday, the return is due the next business day.

Filing frequency. Assigned by the Tax Commission based on the prior year's (or, for new businesses, estimated) annual sales tax liability; accounts are reviewed annually and the seller is notified of any change. Returns must be filed even with zero sales.

Thresholds. $50,000 or less annual sales tax liability = quarterly filer; $50,001 to $96,000 = monthly filer; $96,001 or more = monthly filer with mandatory EFT payments. Current official pages (Pub 25 rev. 08/26, sales tax FAQ) do not list an annual filing frequency.

Prepayments. No prepayment or accelerated-payment schedule is published; large filers ($96,000+ annual liability) must file monthly and pay by EFT. Monthly filers who file and pay on time may take a seller discount of 1.31% of the combined sales tax; quarterly filers are not eligible and late filers lose the discount.

Notes

Utah corporate and individual income tax rate dropped from 4.55% to 4.5% for 2025 tax years (2025 HB 106). Utah's annual business renewal is filed with the Division of Corporations (Department of Commerce), not the Tax Commission, so it is not covered here.
