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

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

Does Wyoming Participate in IFTA?

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

Who Must Register for IFTA in Wyoming?

You generally must register for IFTA in Wyoming 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 Wyoming Department of Transportation provides detailed criteria and registration instructions. Once registered, you receive an IFTA license and decals for each qualified vehicle.

Wyoming IFTA Reporting Periods and Due Dates

Wyoming follows the standard IFTA quarterly calendar:

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