Utah IFTA, IRP, and Fuel-Use Tax Guide (2026)

If your fleet is based in Utah or operates through the state regularly, you'll need to understand how IFTA, IRP, and Utah fuel-use taxes apply to you. This guide covers the essentials.

Does Utah Participate in IFTA?

Yes. Utah is an IFTA member jurisdiction. If Utah is your base state, you file quarterly IFTA returns with the Utah State Tax Commission, reporting fuel use in all participating U.S. states and Canadian provinces. Official guidance is available from the Utah State Tax Commission.

Who Must Register for IFTA in Utah?

You generally must register for IFTA in Utah if you operate a qualified motor vehicle that:

  • Has two axles and a gross vehicle weight over 26,000 lbs, or
  • Has three or more axles regardless of weight, and
  • Travels in more than one IFTA member jurisdiction

The Utah State Tax Commission provides detailed criteria and registration instructions. Once registered, you receive an IFTA license and decals for each qualified vehicle.

Utah IFTA Reporting Periods and Due Dates

Utah follows the standard IFTA quarterly calendar:

  • Q1: January – March → due April 30
  • Q2: April – June → due July 31
  • Q3: July – September → due October 31
  • Q4: October – December → due January 31

If a due date falls on a weekend or legal holiday, your return is typically due the next business day. For the full schedule, see IFTA Reporting Periods and Due Dates.

How to File Utah IFTA Returns Online

Utah carriers can file IFTA returns electronically through the Utah State Tax Commission's online systems. When you use iFuelTax, you can:

  • Generate a report that matches Utah's required fields
  • Use that report as the basis for your online filing
