Utah Income Tax Extension

Option 1: If you don't owe UT taxes and don't expect a refund, you don't need to file an UT tax extension. If you expect an UT tax refund, you must file your UT tax return to receive it.

Option 2: eFiled a Federal Extension? If you do not owe Utah income taxes or expect a tax refund by the tax deadline, your accepted federal extension will be honored as a state extension, and you do not have to mail in Form TC-546.

Option 1: Pay all or some of your Utah income taxes online via: Utah's Taxpayer Access Point. If you pay online, you do not have to file a TC-546 prepayment coupon form.

Option 2: If you owe UT income taxes, you will either have to submit a UT tax return or extension by the tax deadline in order to avoid late filing penalties. You can only eFile and IRS tax extension, but not an Utah extension. The tax extension will only avoid late filing penalties until the October deadline.
Note: Prepayment requirements for filing an extension by the tax deadline:

• 90% of UT 2024 tax due;
• 100% of UT 2023 tax liability;
• 90% of UT 2024 tax due if you do not have a 2023 tax liability or a first time filer.

Option 3: Complete Form TC-546, include a Check or Money Order, and mail both to the address on Form TC-546. Important: Even if you filed an extension, you will still need to file your UT tax return either via eFile or by paper by the October deadline.
