Form Instructions How to File

No form

If you need more time to file your Utah state tax return, you do not need to file an extension form. You'll get an automatic 6-month extension to file your UT return.

The automatic extension to file your UT return is not an extension to pay any state taxes owed. You need to meet the prepayment requirements by April 18, 2018 to avoid a late payment penalty. 

You may prepay through UT tax withholding (Form W-2, Form TC-675R, Form 1099-R, etc.); payments applied from previous year state tax refunds; tax credits and credit carryovers; or payments made by the deadline tax is due using Utah form TC-546, Individual Income Tax Prepayment Coupon, or online at

Interest is collected during the extension period on unpaid tax from the original tax return deadline until the tax is paid in full.

If you do not meet the prepayment requirements by the original tax return deadline, an extension penalty will be added. The penalty is assessed at 2% per month until the date the UT return is filed. To avoid the penalty, you must do one of the following by April 18, 2018:

  • Prepay at least 90% of your 2017 taxes owed (reported on Form TC-40, line 27 plus line 30);
  • Prepay at least 100% of your 2017 taxes owed (reported on Form TC-40, line 27 plus line 30); OR

The taxable value of a property is 100% of its fair market value; this does not include any exemptions that may be permitted. The Utah Constitution permits the Legislature to exempt up to 45% of the fair market value of primary residential property from property taxes.

Prior to May 22 of each year, county assessors ascertain the names of all property owners and assess the property based on its value on January 1 of each Tax Year.

In order to determine the value of a personal property, the Utah State Tax Commission provides a number of classification categories, which are used by all UT county assessors.

The Utah State Tax Commission Property Tax Division has four tax relief programs:

  • Circuit Breaker for taxpayers age 65 or older
  • Veterans exemption
  • Blind exemption
  • Indigent abatement/deferral

  • Sales of any beverage
  • Any other services

The tax is added to any applicable sales tax charged, but it may not be imposed on any sales and use tax collected.

The revenue generated by the tax will be deposited into a special fund for various task forces and treatment programs that deal with sex offenders.
