How to register for an IFTA license in Texas

Texas is your base jurisdiction for IFTA licensing and reporting if you:

  • have qualified motor vehicles registered in Texas that travel on Texas highways
  • have an established place of business in Texas from which motor carrier operations are performed
  • maintain operational control and records for qualified motor vehicles in Texas or can make those records available in Texas.

A motor carrier that enters Texas with a qualified motor vehicle more than five times in a calendar year requires obtaining an IFTA license or interstate trucker license.

You can download a Texas Application for Fuels Tax License (Form AP-133) at comptroller.texas.gov/forms/ap-133.pdf, or contact the Texas IFTA office at 800-252-1383.

Texas IFTA License Costs, Fees, and Penalties

Cost & Fees

There are no fees associated with IFTA registration, licenses or decals.


The minimum penalty is $50 or 10 percent of your total tax liability, whichever is greater. The minimum penalty applies to all late reports including no operations, no tax due and credit reports.

The Texas IFTA office assesses interest on all delinquent taxes due each member jurisdiction. They will calculate interest beginning the day after the due date of the report for each month, or fraction of a month, until paid.

Texas IFTA License Renewal

The Texas IFTA office will determine if you are eligible for automatic license renewal by Dec. 1 each year. If you are eligible, they will automatically issue and mail new IFTA credentials (a license and decals) to you at no cost.
