Before you run a qualified truck across a state line, you need an International Fuel Tax Agreement (IFTA) license from your base state and two decals for that truck. The license renews yearly; the decals are per vehicle, per year, and what an officer looks for from outside the cab. Applying is a base-state process, not a federal one, and in most states it takes days. Here is what to apply for, what to keep in the truck, and what to do if you have to cross before the decals arrive.
Filter: is your truck a qualified motor vehicle?
IFTA applies to a vehicle used interstate with two axles and a gross or registered gross weight over 26,000 pounds, three or more axles regardless of weight, or a combination over 26,000 pounds. Recreational vehicles used for personal travel are outside it.
Two parts are worth reading twice. It is an interstate test, so a qualified truck that never leaves its home state does not need IFTA. And it is a combination test, so a straight truck under the threshold alone can qualify once it pulls a trailer over the 26,000-pound combination limit. If you are working out whether the single-state exemption is yours, do I need IFTA if I stay in one state answers that.
Your base state, and why it is not a choice
You apply in your base jurisdiction: the state where your qualified vehicles are registered, where you keep the operational records, and where some mileage is accrued. It is not the state with the friendliest fee, and applying in the wrong one gets sorted out later at your expense.
The base state is also who you deal with downstream: the license, the decals, the quarterly returns, and any audit. One jurisdiction collects and distributes fuel tax to the others on your behalf. That is the point of the agreement, and why a single license covers all member jurisdictions instead of one permit per state line.
What the application asks for
- Your legal business name and EIN, as on your registration and USDOT record.
- Your USDOT number, and your MC number if you have operating authority.
- Vehicle details for each qualified truck: VIN, make, year, registered gross weight, and fuel type.
- The number of decal sets, one set of two per qualified vehicle, for the trucks you will run this year.
- The fee, which varies by jurisdiction: nothing in some states, typically under twenty dollars per set elsewhere.
Most base states take the whole application online and issue the license number the same week, with decals mailed after. Forms, fees, and jurisdiction contacts are published on the official IFTA, Inc. site, the body that administers the agreement between member jurisdictions.
If you would rather have the application prepared and filed along with the rest of the fuel-tax setup, that is what our IFTA registration and reporting service covers.
Where the license and the decals go
The two decals go on the exterior of the cab, one on each side, readable without opening a door. A copy of the license goes in the truck: most jurisdictions accept a legible photocopy or an electronic image, several now accept it on a phone, but the original stays with your records.
Running without decals displayed, or without the license in the cab, is a citable violation even when your account is current and your returns are filed. The paperwork exists, it just is not where the officer can see it.
Timing, renewals, and the crossing you have to make this week
The decal year runs January 1 through December 31. Renewals open in the fall, and most jurisdictions let you display the prior year’s decals into the first two months of the new year while the renewal is processed, provided you applied for it. Do not lean on that grace window: it covers mail, not procrastination.
If a load crosses a state line before your decals arrive, buy a temporary fuel permit for that trip in the state you are entering. Permits cost more per crossing than IFTA does per year, which is the argument for getting the license in place first, but they are legal and they keep the truck moving. Some base states also issue a temporary IFTA permit while decals are in transit, so ask first.
What the license commits you to
Getting the license is the small half. Holding it means filing a quarterly return in your base state on the last day of the month after each quarter ends, even in a quarter where the truck never moved. A zero return is still a return, and a missed one is a penalty plus interest, with revocation on the far end of a pattern.
It also means keeping the records the return is built from: miles and fuel purchased by jurisdiction, with receipts, retained for four years. Start on day one; reconstructing a quarter from memory is where most first-year IFTA pain comes from. The first filing is covered in how to file your first IFTA quarterly return.
Quick answer recap
Qualified vehicle plus interstate travel equals an IFTA license from your base state and two decals per truck. Apply where the truck is registered and the records are kept, not the cheapest state. Decals on both sides of the cab, a copy of the license inside. Decal year is the calendar year, with a two-month display grace at renewal. Trip permits cover a crossing you cannot wait for. The license commits you to quarterly returns, including zero ones, and four years of mileage and fuel records.
Next step
Confirm your base state, gather the VIN and registered gross weight for each qualified truck, and get the application in before the load that needs it. If you want the license, the decal order, and the filing calendar handled as one setup instead of three errands, our IFTA registration and reporting service takes it from the application through the first return.
