International Fuel Tax Agreement (IFTA)

To simplify the reporting of fuel used by interstate and inter-jurisdictional motor carriers, Maryland participates in the International Fuel Tax Agreement (IFTA). IFTA is an agreement among 48 participating states and 10 Canadian provinces which allows qualified commercial vehicles to travel throughout those jurisdictions and pay the required motor carrier taxes. Vehicles displaying valid licenses and decals issued by a base jurisdiction may travel in any other jurisdiction.

The Comptroller of Maryland was proud to be responsible for legislation which repealed the motor carrier decal fee beginning in 2001. The Motor Fuel Tax office added another high-tech convenience in 2002, which allowed motor carriers to submit their applications for IFTA decals over the Internet. Today, taxpayers can also file their quarterly IFTA motor carrier returns electronically and use a host of other online services.

The Revenue Administration Division has provided various video modules to help IFTA users better understand the new Explore IPC IFTA Processing system. 

For more information about IFTA qualifications or additional registration requirements under the Maryland Department of Transportation, see the links below or the MDOT Motor Carrier Program.

Important Information for IFTA Licenses - License Renewal

The Comptroller of Maryland will attempt to automatically renew your IFTA license and issue decals.  

  • If you have delinquent IFTA returns or any Maryland State agency liabilities, you will not be eligible for automatic renewal.  These liabilities must first be resolved, and then an online or paper IFTA application must be submitted and approved before we will issue your IFTA license and decals.  
  • Other possible situations associated with your current IFTA license may cause your IFTA license to not automatically renew, including being licensed under a USDOT that is registered to another company, or if your current IFTA returns indicate that you do not travel outside of Maryland.  These situations will require you to submit an online or paper application for approval before we will issue your IFTA license and decals.
  • If you do not travel outside of the State of Maryland, you do not need to register for IFTA.

If you receive a renewal form in the mail, your account was not included in the automatic renewal and you are required to complete a renewal application to receive your IFTA license and decals.  The deadline for IFTA license renewals is December 31.   

The most efficient way to obtain your IFTA license and decals is to renew online.  Online renewal will be available as of December 1.  If you are currently registered to file online returns, you do not have to re-register to renew online.  If you choose not to take advantage of the online renewal option, you can renew by using the paper renewal form. When your renewal has been received and approved, we will send your IFTA license and decals to you through the mail.  It is your responsibility to renew your IFTA license and decals before they expire.

If you are aware of any problems that may prevent your renewal, we strongly suggest you resolve them now. If your IFTA license is not renewed and decals are not assigned to you by December 31, you cannot legally operate in any other jurisdiction without a valid trip permit.

Please call us at (410)260-7215 or Maryland toll free at 1-888-784-0142 if you have any questions.
