Do I need IFTA?
Two questions decide it. Is the vehicle a qualified motor vehicle, and does it cross the boundary of an IFTA member jurisdiction? Two yeses and you need a licence and decals.
The qualified motor vehicle test
A vehicle used, designed or maintained to transport property or people, and meeting any one of these:
| Test | Qualified? |
|---|---|
| Two axles, gross or registered gross weight over 26,000 lb | Yes |
| Three or more axles, any weight | Yes |
| Used in a combination whose weight exceeds 26,000 lb | Yes |
| Recreational vehicle used purely for personal pleasure | No |
| Two axles, under 26,000 lb, no heavy trailer | No |
Note what is not in the test: whether you are loaded, whether you are for hire, or how far you went. A three-axle truck that crosses one state line empty is a qualified motor vehicle on an IFTA trip.
The membership part
IFTA covers 48 US states and 10 Canadian provinces. Alaska, Hawaii and the District of Columbia are not members, and neither are the Canadian territories. Miles run in a non-member jurisdiction are not IFTA miles — they follow that jurisdiction's own rules instead.
The occasional-trip alternative
If you cross a line two or three times a year, a fuel trip permit bought from that jurisdiction is usually cheaper and simpler than holding a licence and filing four returns. The break-even comes quickly though: permits run tens of dollars each, and the moment interstate work becomes regular the licence is both cheaper and less hassle than remembering to buy permits.
IFTA and IRP are different things
| IFTA | IRP | |
|---|---|---|
| Settles | Fuel tax | Vehicle registration |
| Filed | Quarterly | Annually |
| Evidence | Decals and a licence | Apportioned plate and cab card |
| Built on | Jurisdiction miles and fuel | Jurisdiction miles |
Both run off the same mileage records, which is the practical argument for keeping those records properly once rather than twice — see IFTA miles by state. Starting out? The full registration checklist is here.
Questions
Do I need an IFTA licence?
If you operate a qualified motor vehicle across the boundary of an IFTA member jurisdiction, yes. A qualified motor vehicle is one used to carry property or people that has two axles and a gross or registered gross weight over 26,000 lb, or three or more axles at any weight, or is used in a combination over 26,000 lb.
Do I need IFTA if I only run in one state?
No. IFTA exists to settle fuel tax between jurisdictions. Purely intrastate operation does not need it — though your state will have its own fuel tax arrangements.
Is a pickup and trailer over 26,000 lb covered?
If the combination's gross or registered gross weight exceeds 26,000 lb and it crosses jurisdiction lines carrying property for business, yes — the vehicle type does not matter, the weight and axle test does. Recreational vehicles used purely for personal pleasure are excluded.
What if I cross a state line only occasionally?
You can buy a temporary fuel trip permit from the jurisdiction instead of holding an IFTA licence. That works for the rare trip; it gets expensive quickly if it happens monthly.
Is IFTA the same as IRP?
No, and both are usually needed. IRP apportions your registration across jurisdictions; IFTA settles your fuel tax. They use similar mileage records, which is why carriers usually do them together.
