# What Is a Base Jurisdiction? How IFTA and IRP Decide Where a Carrier Files

A carrier files IFTA and IRP in one place, its base jurisdiction, and that jurisdiction collects for all the others. Which province or state qualifies is a question of where the business really is, not where it would like to be. Here's the test, what happens when a carrier has operations in several places, and why the choice cannot be made for the fee schedule.

## One Filing, One Jurisdiction

Both IFTA and IRP work by letting a carrier deal with a single jurisdiction. The carrier licenses, files and pays there, and that jurisdiction settles with every other member on the carrier's behalf. The jurisdiction that plays that role is the base jurisdiction, and each agreement defines it in nearly the same words: the member jurisdiction where the carrier has an established place of business, where its qualified vehicles are based for registration, where its operational records are kept or can be made available, and where some of its distance is accrued.

## What 'Established Place of Business' Means

A physical location owned or leased by the carrier, with a street address, open during business hours, staffed by people employed by the carrier who conduct its trucking business there, and the location where the carrier's operational records are kept or can be produced. A mailbox, a registered agent, an accountant's office or a driver's home does not qualify. IRP's rules list the evidence a jurisdiction may ask for — tax filings, utility bills, payroll records — and jurisdictions do ask, because a carrier that bases in a low-fee jurisdiction without really being there is a carrier the other members are subsidizing.

## Carriers in More Than One Place

A carrier with terminals in Quebec and Ontario chooses one as its IFTA base, generally where the head office and records are, and files all its fuel tax there. For IRP, a carrier may register separate fleets in different base jurisdictions if each fleet is genuinely based there, or consolidate; the vehicles of a given fleet are based in one jurisdiction. Cross-border carriers base in their home country: a Montreal carrier's base is Quebec even if most of its miles are in New York, and its New York obligations — HUT, for instance — are filed with New York directly, separately from IFTA and IRP.

## Why the Base Matters to the Records

The base jurisdiction is also the auditor. Its staff audit the carrier's IFTA and IRP records on behalf of all members, and they ask for distance by jurisdiction per vehicle, tied to trips and dates, and fuel purchases by jurisdiction with receipts. The telematics jurisdiction report and the fuel records behind it are what the base jurisdiction's auditor works from, and a carrier that keeps them in one platform answers the audit in a day. High Point GPS sets up the reporting for carriers based in Quebec and Ontario and for US carriers in the northeastern states.

## FAQ

### What is a base jurisdiction?

The one member state or province where a carrier licenses, files and pays for IFTA or IRP, chosen because the carrier has an established place of business there, bases its vehicles there and keeps its records there.

### Can I choose a base jurisdiction with lower fees?

No. The base must be where the carrier genuinely has an established place of business with staff and records. Jurisdictions verify this.

### Can a carrier have different bases for IFTA and IRP?

Usually the same jurisdiction, but IRP allows separate fleets to be based in different jurisdictions if each fleet is genuinely based there.

### Is my base jurisdiction the auditor?

Yes. The base jurisdiction audits the carrier's IFTA and IRP records on behalf of all member jurisdictions.

### Does a Quebec carrier running mostly in New York base in New York?

No. Its base remains Quebec, where its business is. New York-specific obligations like HUT are filed with New York separately.
