FAQ
When is the LLC tax filing deadline in Utah for 2026?
The Utah LLC tax return is due Mar 16, 2026 for the 2026 tax year. An extension is available until Sep 15, 2026.
Does Utah require LLC estimated tax payments?
Estimated payments are not typically required at the entity level for LLC in Utah, but confirm with Utah State Tax Commission.
What form do I file for a LLC in Utah?
LLC entities in Utah file using Form State LLC return. You can download the form from Utah State Tax Commission at https://tax.utah.gov.
Can I get an extension for my Utah LLC tax return?
Yes. Utah allows an extension for LLC returns until Sep 15, 2026. Note that an extension gives you more time to file, not more time to pay — any tax owed is still due by the original deadline of Mar 16, 2026.
What are the penalties for filing late in Utah?
Utah typically charges a failure-to-file penalty (usually 5% of unpaid tax per month, up to 25%) and a failure-to-pay penalty (usually 0.5-1% per month). Interest also accrues on unpaid balances. Filing for an extension by the original deadline avoids the failure-to-file penalty but not the failure-to-pay penalty.
