International Fuel Tax Agreement (IFTA) Refunds and Credits
Credits with amounts greater than the $14.99 will be automatically refunded.
For amounts less than $14.99, the taxpayer will need to request a refund from the Comptroller's office. If a refund is not requested, then all credits (at any amount) will remain open for eight quarters and can be applied to other IFTA report periods that may have a liability.
To request a refund of taxes paid in error, taxpayers must provide the Comptroller's office with the following information:
- Original or amended Form 56-101, Texas International Fuel Tax Agreement (IFTA) Report (PDF) and Form 56-102, IFTA Fuel Tax Report Supplement (PDF);
- the amount of refund requested;
- Form 01-137, Power of Attorney (PDF) or other written authorization, if being represented by an authorized agent.
