What is the deadline for filing state taxes in Utah?

The deadline for filing state taxes in Utah is typically April 15th, mirroring the federal tax deadline. However, if this date falls on a weekend or holiday, the deadline is typically extended to the following business day. It's important to note that taxpayers can request a six-month extension to file their state taxes by submitting Form TC-546, which shifts the deadline to October 15th. Though an extension provides additional time to file, it doesn't extend the payment due date. Taxes owed must still be paid by the original deadline to avoid penalties and interest. Therefore, it's prudent to pay any state taxes owed by the April 15th deadline, regardless of the extension status.
