Base Jurisdiction (IFTA)
The single state or province where a carrier registers for IFTA, based on having an established physical place of business there, not just a mailing address. That jurisdiction processes one quarterly return and handles distributing tax owed to every other jurisdiction the fleet drove in.
What Base Jurisdiction means in practice
A base jurisdiction is the single member state or province where a carrier licenses, files and pays for IFTA and IRP, and it settles with every other member on the carrier's behalf. It is decided by where the business really is, not by which fee schedule looks best. The test is an established place of business: a physical location with a street address, open during business hours, staffed by the carrier's own employees, where 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, and jurisdictions ask for evidence such as payroll records and utility bills.
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 New York-specific obligations such as HUT are filed with New York separately.
The base is also the auditor. Its staff audit IFTA and IRP records on behalf of every member jurisdiction and ask for distance by jurisdiction per vehicle, tied to trips and dates, plus fuel receipts. A carrier that keeps the telematics jurisdiction report and fuel records in one platform can answer that audit in a day.

Base Jurisdiction: common questions
Can I choose a base jurisdiction with lower fees?
No. Your base jurisdiction must be where the carrier genuinely has an established place of business, with its own staff working there and its operational records kept there. Jurisdictions verify this and can ask for evidence such as tax filings, utility bills and payroll records, because a carrier based somewhere it does not really operate is subsidized by the other members.
Can a carrier have different base jurisdictions for IFTA and IRP?
Usually the base is the same for both. IRP does allow a carrier to register separate fleets in different base jurisdictions, as long as each fleet is genuinely based where it is registered. A carrier with terminals in two provinces generally files all its IFTA fuel tax in one, typically where the head office and records are.
Does a Quebec carrier that runs mostly in New York base in New York?
No. A cross-border carrier bases in its home country, so a Montreal carrier's base jurisdiction stays Quebec even if most of its miles are driven in New York. Obligations that belong only to New York, such as the Highway Use Tax (HUT), are filed directly with New York, separately from IFTA and IRP.
