How to get a Texas IFTA license and keep it current

The license is free and the application is short. What causes trouble is the paperwork around it: the right base jurisdiction, credentials in every cab, and fuel and mileage records that hold up in an audit.

To get a Texas IFTA license, a Texas-based carrier applies to the Texas Comptroller through Webfile or on paper Form AP-178. There is no fee. The Comptroller mails one license and two decals per qualified vehicle, valid January 1 to December 31, and renews eligible accounts automatically.

Texas makes the IFTA license itself easy: no fee, a short online application, and automatic renewal for carriers in good standing. The work is in everything around it, from the legal name on the application to the unit number on a fuel receipt.

This guide is for Texas-based carriers getting or keeping a Texas IFTA license. It covers who qualifies, what to have ready, how decals and renewal work, and the records the Comptroller expects you to keep.

The Short Version

Key takeaways

Texas must be your base jurisdiction

Your qualified vehicles are registered in Texas, you run operations from a Texas place of business, and your records are kept or available in Texas.

Apply on Webfile or Form AP-178

There is no fee for the license or decals, and the online application takes about 10 minutes.

No temporary license for new applicants

Until the license and decals arrive by mail, a truck that leaves Texas needs fuel trip permits.

Credentials run January 1 to December 31

Eligible accounts renew automatically, and last year's credentials are honored through the end of February.

Records must tie fuel and miles to each truck

Keep them four years. Fuel card receipts must show which unit was fueled.

Eligibility

Who needs a Texas IFTA license?

A Texas-based carrier needs a Texas IFTA license, or fuel trip permits for every trip, when it runs a qualified motor vehicle in Texas and at least one other IFTA jurisdiction. There is no mileage threshold.

A qualified motor vehicle carries people or property and has:

  • Two axles and a gross or registered gross vehicle weight over 26,000 pounds (11,797 kg)
  • Three or more axles, regardless of weight (only the power unit's axles count)
  • Or a combination weight over 26,000 pounds (11,797 kg)

The combination rule catches hotshot pickups. The Comptroller treats a pickup pulling a trailer over 26,000 pounds combined as qualified. Once it is licensed, all of its miles for the license year go on the return, with or without the trailer.

Is Texas your base jurisdiction?

Texas is your base jurisdiction when all three of these are true:

  • Your qualified vehicles are registered in Texas and travel on Texas highways
  • You have an established place of business in Texas from which you run motor carrier operations
  • You keep operational control and records in Texas, or can make the records available there

If you have held an IFTA license in another jurisdiction, you must be in good standing there before Texas will license you. Carriers that run only between Texas and Mexico can't get an IFTA license; they need a Texas interstate trucker license or a trip permit for each entry.

A carrier that leaves Texas only now and then can buy fuel trip permits instead, as our temporary fuel permit guide explains. If you are still setting up the company, our guide to starting a trucking company in Texas shows where IFTA fits among the other credentials.

Before You Apply

What do you need before you apply?

You need your federal and state identification numbers, plus a clear answer on which trucks need decals and who files the returns. The Texas Comptroller asks applicants to have ready:

  • Social Security numbers for the sole owner, corporate officers or directors, or LLC members
  • A Federal Employer Identification Number (FEIN) for business entities
  • A Texas taxpayer number, if the business is registered in Texas
  • Your IRP cab card account number, or each vehicle's license plate number if you have no IRP account
  • Your USDOT number
  • A national ID number for each officer or partner, if the entity is applying from another country

Form AP-178 also asks for details that are easy to get wrong:

  • Legal name. Corporations and LLCs enter the name exactly as registered with the Texas Secretary of State.
  • Business location. A street address, not a P.O. box or rural route. The mailing address is where the license and decals will go.
  • Filing contact. The person responsible for filing tax returns, with a daytime phone and email.
  • Fleet details. How many vehicles need decals, every fuel type they use, and every jurisdiction where you operate or keep bulk fuel.
  • History. Any IFTA license from another jurisdiction, and any suspension or revocation.

Who files when the truck is leased?

Settle it in writing before you apply. For leases of 30 days or more, the lessor and lessee can choose which of them reports the fuel tax. For shorter leases, the lessor reports unless the contract names the lessee and the lessor holds a copy of the lessee's valid IFTA license.

Step by Step

How to apply for a Texas IFTA license

Apply through the Comptroller's Webfile system or on paper Form AP-178. Either way, Texas charges no fee for IFTA registration, the license, or the decals.

Step 1: Apply on Webfile or on paper

On Webfile, create an eSystems profile first if you don't have one; the application itself takes about 10 minutes. On paper, send Form AP-178 by mail, fax, or email. A field office will accept it, but only forwards it for processing.

Step 2: Pick a realistic effective date

AP-178 asks when you want the license to start. It can't be earlier than the date the Comptroller receives the application, so apply before the first out-of-state run, not after it.

Step 3: Plan for the wait

Applications are processed in the order received, and the license and decals come by mail. Texas issues no temporary IFTA licenses, and new applicants can't get temporary decals. Until your credentials arrive, a truck that leaves Texas needs fuel trip permits for the jurisdictions it enters.

Step 4: Check and place the credentials

You get one license for the whole fleet and two decals for each qualified vehicle. Put a legible copy of the license in every qualified truck and fix one decal on each side of the cab. Once affixed, a decal can't be moved to another truck.

A truck without a copy of the license is not treated as operating under it. That can mean a citation and a trip permit at every state line.

Every Year

How do Texas IFTA decals and renewals work?

Texas IFTA licenses and decals are valid January 1 through December 31. Eligible Texas carriers don't file a renewal application: the Comptroller decides eligibility by December 1 and mails new credentials at no cost.

What can block automatic renewal?

The Comptroller may deny renewal if you failed to file any IFTA return, failed to pay tax due to any member jurisdiction, or reported no interstate travel in the preceding six consecutive quarters.

It will not renew if you are delinquent on any tax or fee it administers, your registration with the Texas Secretary of State is forfeited or canceled, or you are delinquent on child support or student loans.

Adding a truck during the year

Request extra decals at no cost by phone, at a field office, or in writing. Expect to verify the account, for example with your Webfile number or the total miles on your last return, and to give each truck's cab card or its VIN or plate, year, make, owner, and operating company. Then put a copy of the license in the new truck.

An honest caveat. Automatic renewal depends on mail reaching you. The new license and decals go to the mailing address on file, so update it when you move, and confirm the credentials arrived before the grace period ends.
Recordkeeping

What records does a Texas IFTA licensee keep?

Keep distance and fuel records for every qualified vehicle for four years from the return's due date or filing date, whichever is later. The full list of trip and receipt fields is in our IFTA quarterly return guide. These are the Texas points that most often cause audit findings:

  • Fuel card receipts must name the truck. Either assign each card to one vehicle, or write the unit or plate number on the receipt. You also need a monthly summary of miles and fuel for each licensed vehicle.
  • The purchaser is the company. The receipt names the business the fuel was bought for, not the driver.
  • No altered receipts. Texas won't accept receipts with alterations or erasures.
  • Trips must chain together. Each trip's starting odometer should match the last trip's ending reading. Unexplained differences, called gap miles, are an audit issue, and auditors assign them to where the truck most likely ran.
  • Every Texas mile is taxable. Texas has no tax-exempt miles, so on-highway and incidental off-highway miles in Texas all count.
  • Bulk tanks need their own records. Withdrawals by tank, date, gallons, fuel type, and unit number, plus a quarterly inventory reconciliation for each tank.

GPS-based records must show the date, time, and location of each reading at intervals that validate the miles in each jurisdiction, plus odometer or ECM readings and the unit number. Our guide to using your ELD for IFTA covers that setup.

When records fall short in an audit, the Comptroller can estimate your fuel use, apply 4.0 miles per gallon, cut your reported MPG by 20%, or disallow tax-paid fuel you can't document. The burden of proof is on you, and audits come with at least 30 days' notice.

After Approval

What does the license commit you to each quarter?

A Texas IFTA license means a return every quarter, even in a quarter with no miles or no fuel. Texas expects returns through Webfile or EDI, accepts paper Forms 56-101 and 56-102 only in hardship cases, and doesn't allow annual filing.

Returns are due the last day of the month after each quarter, moved to the next business day when that falls on a weekend or legal holiday. The minimum late penalty is $50 or 10% of the tax, whichever is greater, and it applies to late no-operations and credit returns too. Interest is added for each month or part of a month.

If you stop running interstate, cancel the license rather than going quiet. File the final return, send back the license and unused decals, and keep your records four years after the last report's due date. An unfiled return leads to an estimated assessment, and a suspended or revoked Texas license also suspends or revokes any other IFTA license you hold.

If keeping up with returns in-house isn't realistic, our trucker tax team can prepare and file them for you.

Your Questions, Answered

Frequently asked questions

How much does a Texas IFTA license cost?+
Nothing. Texas charges no fee for IFTA registration, the license, or the decals, including extra decals for trucks you add during the year. You pay only the fuel tax your quarterly returns show is due.
How do I apply for an IFTA license in Texas?+
Apply online through the Texas Comptroller's Webfile system, or send Form AP-178 by mail, fax, or email. Texas must be your base jurisdiction, and you'll need your FEIN or SSN, USDOT number, and IRP cab card account number or plates.
Can I run out of state while my application is pending?+
Not under IFTA. Texas issues no temporary IFTA licenses, and new applicants can't get temporary decals. Until the credentials arrive, buy fuel trip permits for the jurisdictions you enter.
Do I need to renew my Texas IFTA license?+
Not with an application. The Comptroller decides by December 1 whether you qualify for automatic renewal and mails a new license and decals. Unfiled returns, unpaid tax, or six quarters without interstate travel can block it.
Is Form 56-101 the Texas IFTA application?+
No. The application is Form AP-178. Forms 56-101 and 56-102 are the quarterly IFTA fuel tax report and its supplement, used for paper filing in hardship cases.
Is IFTA the same as IRP?+
No. IFTA is a fuel tax license issued by the Texas Comptroller. IRP is apportioned registration, and the Texas cab card comes from the Texas Department of Motor Vehicles. The IFTA application asks for your cab card account number.
