State of Utah
Business Income Tax Extensions

Utah Filing Due Date: Corporation and partnership tax returns are due by April 15 — or by the 15^th day of the 4^th month following the end of the taxable year (for fiscal year filers).

Extended Deadline with Utah Tax Extension: Utah offers a 6-month extension, which moves the business filing deadline to October 15 (for calendar year filers).

Utah Tax Extension Form: There is no Utah extension application or written request to submit. As long as your Utah tax is properly paid on time, you can automatically receive a Utah tax extension.

Utah Extension Payment Requirement: An extension of time to file is not an extension of time to pay. If you owe Utah tax, it must be paid by the original due date, or penalties and interest will apply. In order to get a Utah extension, you must pay either 90% of the current year’s tax balance or 100% of the prior year’s tax balance. You can make a Utah extension payment with Form TC-559, or pay electronically through the TaxExpress portal: taxexpress.utah.gov
