Modified on Wed, 10 Jun at 2:54 PM

Utah accepts the federal extension. If you file IRS Form 4868 to extend your federal return, Utah will honor it for your state return.

Common Questions About Utah Extensions

Does Utah accept the federal extension for individuals?

Yes. Utah accepts the federal extension, meaning if you file IRS Form 4868, you automatically receive a Utah extension. However, you must still pay any Utah balance due by April 15 to avoid penalties.

Does Utah require estimated tax payments?

Yes. If your withholding and credits do not cover at least 90% of this year’s liability (or 100% of your prior year’s liability), you must make quarterly estimated payments to avoid penalties.

Does Utah have a state income tax?

Yes. Utah imposes a flat state income tax rate on Utah taxable income. Your state return starts with your federal AGI and applies Utah-specific adjustments. This is why many taxpayers search for “Utah state income tax extension” when planning their filings.

Where do I get Utah Form TC-546?

You can download Form TC-546 here. Use it if you are mailing an extension payment by check or money order. This is often referred to as the “Utah extension payment coupon.”

What is the Utah Taxpayer Access Point?
