Navigating the Texas Comptroller Webfile

Texas is a massive logistics hub, meaning thousands of owner-operators file their IFTA here. The Texas Comptroller Webfile system is robust but can be tricky for first-timers.

Step 1: The Timeout Clock

Warning: The Texas Webfile system has a strict timeout (usually 30 minutes of inactivity). Have all your numbers ready before you log in. If you try to calculate while logged in, the system might kick you out and you'll lose your progress.

Step 2: Required Data Inputs

Texas requires you to input specific line items. You will need:

• Total IFTA Miles: All miles driven in IFTA jurisdictions.
• Total Non-IFTA Miles: Miles driven in non-member jurisdictions (e.g., Mexico) or off-highway miles if approved.
• Taxable Gallons: Fuel consumed in each jurisdiction.
• Tax Paid Gallons: Fuel purchased at the pump in each jurisdiction.

Step 3: Payment Methods

Once filed, you can pay via:

• Credit Card: Subject to a convenience fee.
• Electronic Check (WebEFT): No fee, direct debit.
• TEXNET: Required for payments over $10,000, but available to anyone.

The "Copy-Paste" Method: FastIFTA exports a report specifically formatted to match the line items of the Texas return. Instead of fumbling with a calculator and risking a timeout, you simply read the numbers from your FastIFTA PDF and type them into the Webfile boxes. Done in 5 minutes.
