Washington runs apportioned registration out of the same Department of Licensing unit that runs IFTA, so a carrier sets up both accounts in one place and files both in License Express. New accounts need a stamped Form 2290, proof of an established place of business or residency, current Washington registrations that match the account name exactly, and the USDOT number of whoever is responsible for the vehicle's safety.
Washington IRP administration
- Office
- Prorate and Fuel Tax Services, Motor Carrier Services (MCS) unit, with counters in Olympia and Vancouver
- Process
- Apply through License Express for prorate and fuel tax, or bring the paperwork to a prorate and fuel tax office. Every document listed under required_documents has to be in before an account is created. Once registered, each vehicle gets one set of apportioned plates, front and back, and an original cab card.
- Fee structure
- Washington does not publish an apportioned fee table on its registration page. Motor Carrier Services collects the licence and freight fees for every jurisdiction the vehicle is licensed in and distributes them, and the department quotes the fees when it processes the application.
- Fees: how to estimate
- License Express shows Washington and other jurisdiction fees immediately when the application is filed there. IRP, Inc. and the IRP Customer Manual carry the related fees, and the Celtic calculator at IRP, Inc. gives an estimate.
- Cab card
- Each registered vehicle gets one set of apportioned plates for the front and back plus an original cab card, and the cab card lists every IRP state and Canadian province, authorising travel in all of them.
- Cab card: carry rule
- The original cab card must be in the vehicle at all times. Faxes and photocopies are not valid.
- Cab card: plates
- IRP plates are not transferable when the registered vehicle is sold and must be returned to the department immediately.
- Process: what the system does
- Manages IRP accounts and customer profiles, submits documents, takes payments, shows account balances, corresponds with MCS staff, adds and deletes vehicles, sets up new accounts and fleets, raises or lowers declared gross vehicle weight, replaces cab cards and plates, and completes renewals.
More Washington IRP rules
- Qualifying vehicles: summary
- A carrier can apportion a commercial vehicle over 26,000 pounds gross vehicle weight operating in two or more jurisdictions, a vehicle with three or more axles regardless of weight, or a combination whose total gross or registered gross weight is over 26,000 pounds. The vehicle has to be titled in Washington and operating in two or more jurisdictions.
- Qualifying vehicles: excluded
- Recreational vehicles, restricted farm plates, government owned vehicles and school buses are outside apportioned registration.
- Base jurisdiction rules: summary
- Washington is the base jurisdiction for vehicles titled in Washington and operated in two or more jurisdictions. The account application requires a completed Established Place of Business, Residency, or Change of Address form, so basing is proved on that form rather than asserted on the application.
- Base jurisdiction rules: note
- The department's registration page does not reproduce the IRP Plan's own established place of business test; it points to the IRP Customer Manual and IRP, Inc. for the detail, so no element-by-element test is recorded here.
- Required documents: place of business
- Established Place of Business, Residency, or Change of Address form
- Required documents: registrations
- Current copies of Washington vehicle registrations, or validated copies of record, matching the IRP account name exactly
- Required documents: USDOT
- The USDOT number of the motor carrier, and where it differs, the USDOT number of the carrier responsible for vehicle safety, supported by the Leased vehicle listing form and the lease agreement
- Renewal: summary
- A renewal notice is mailed 90 days before the account expires, with instructions for completing the renewal. Renewals are processed in License Express.
- Recordkeeping: summary
- Mileage records are kept for every registered vehicle and summarised monthly, quarterly and annually by fleet and by jurisdiction.
- Recordkeeping: retention
- IRP vehicle mileage records are kept for four years following the period the registration application was based on, and the department separately states a three year retention after the close of that application registration year on its own page; a carrier should keep to the longer four year period the recordkeeping section states.
- Recordkeeping: detail
- Records must cover carrier name, fleet number, operator equipment number or VIN, beginning and ending odometer or hub readings per trip, trip start and end dates, origin and destination by city with every pick up, delivery and fueling location, routes of travel, mileage by state or province split highway, non-highway and deadhead, total trip distance, and original fuel invoices. Federal driver daily logs are kept the same four years where they are the only source documentation.
- Recordkeeping: aid
- The department publishes an IFTA and IRP Individual Trip Report for carriers recording trips by hand.
- Audit: summary
- Records must substantiate what was filed with the department and are subject to review by audit. Missing or inadequate records can result in audit adjustments to fuel consumption, tax-paid credits, jurisdictional distances or the money owed.
- Prism: summary
- Washington participates in the Performance and Registration Information Systems Management program, the cooperative federal and state safety program that links FMCSA safety information to the state's motor vehicle registration process and is designed to identify motor carriers and their fitness to register their trucks.
- USDOT requirement: summary
- The account carries the USDOT number of the motor carrier and, where different, of the carrier responsible for vehicle safety. The registrant's Motor Carrier Identification Report (MCS-150) must be updated every two years and filed with FMCSA; the Department of Licensing states it no longer updates that form for carriers.

Base jurisdiction, renewal, and audit in detail
The rules that decide whether Washington can be your base jurisdiction, what qualifies, and what happens at renewal and audit. Each one is sourced.
- Base jurisdiction rules: Summary
- Washington is the base jurisdiction for vehicles titled in Washington and operated in two or more jurisdictions. The account application requires a completed Established Place of Business, Residency, or Change of Address form, so basing is proved on that form rather than asserted on the application.
- Base jurisdiction rules: Note
- The department's registration page does not reproduce the IRP Plan's own established place of business test; it points to the IRP Customer Manual and IRP, Inc. for the detail, so no element-by-element test is recorded here.
- Qualifying vehicles: Summary
- A carrier can apportion a commercial vehicle over 26,000 pounds gross vehicle weight operating in two or more jurisdictions, a vehicle with three or more axles regardless of weight, or a combination whose total gross or registered gross weight is over 26,000 pounds. The vehicle has to be titled in Washington and operating in two or more jurisdictions.
- Qualifying vehicles: Excluded
- Recreational vehicles, restricted farm plates, government owned vehicles and school buses are outside apportioned registration.
What the Washington share of the fee is built from
An IRP bill is the base jurisdiction's own registration fee for the vehicle, apportioned by mileage, plus the same for every other jurisdiction on the cab card. These are the Washington inputs to that calculation, each with its official source.
Setting up a Washington IRP account
Apply through License Express for prorate and fuel tax, or bring the paperwork to the Olympia or Vancouver counter. Every document on the required list has to be in before an account is created: the application itself, an established place of business or residency form, a Form 2290 showing the current heavy vehicle use tax payment, current Washington registrations that match the account name exactly, and the USDOT number of the motor carrier plus, where it differs, of the carrier responsible for vehicle safety.
A vehicle qualifies if it is titled in Washington, operates in two or more jurisdictions, and is over the published gross weight line or has three or more axles whatever its weight. Recreational vehicles, restricted farm plates, government owned vehicles and school buses sit outside apportioned registration.
What it costs, and how to find out
Washington publishes no apportioned fee schedule on its registration page. Motor Carrier Services collects the licence and freight fees for every jurisdiction a vehicle is licensed in and distributes them, and it quotes the fees when it processes the application. A carrier is charged only for the jurisdictions it has actual travel in.
Filing in License Express shows Washington and other jurisdiction fees straight away, and IRP, Inc. publishes a calculator for an estimate. Rather than reproduce a number Washington does not print, this page records what the department does say and points at the two places that will price your fleet.
Plates, cab cards and renewal
Each registered vehicle gets one set of apportioned plates for the front and back, plus an original cab card listing every IRP state and Canadian province, which authorises travel in all of them. The original has to be in the vehicle at all times; faxes and photocopies are not valid. Plates are not transferable when a registered vehicle is sold and go back to the department immediately.
A renewal notice is mailed ninety days before the account expires, and renewals are processed in License Express.
Records, audit and PRISM
Mileage records are kept for every registered vehicle and summarised monthly, quarterly and annually by fleet and by jurisdiction. Washington's own page gives one retention period in its recordkeeping section and a shorter one elsewhere, so keep to the longer of the two. Records have to substantiate what was filed, and missing or inadequate records can bring audit adjustments to fuel consumption, tax-paid credits, jurisdictional distances or the money owed.
Washington takes part in PRISM, the federal and state program that links FMCSA safety information to state vehicle registration. The registrant's MCS-150 has to be updated every two years with FMCSA, and the department states plainly that it no longer updates that form for carriers.
What pairs with IRP
The same interstate operation that needs apportioned plates almost always needs an IFTA license through Washington, and heavy power units owe the federal Form 2290 heavy vehicle use tax before plates renew. To compare how other states run IRP, see the national IRP registration table.
Frequently asked questions
Where do I register for IRP in Washington?
- With the Department of Licensing, through License Express for prorate and fuel tax, or in person at the Olympia or Vancouver prorate counter. The same unit handles IFTA, so both accounts open in one place.
How are Washington apportioned fees calculated?
- By distance share across the jurisdictions a fleet actually runs in. Washington publishes no fee schedule on its registration page; Motor Carrier Services quotes the amount when it processes the application, and License Express shows the figures as soon as the application is filed there.
What documents does a new Washington IRP account need?
- The application, an established place of business or residency form, a Form 2290 showing the current heavy vehicle use tax payment, current Washington registrations matching the account name exactly, and the USDOT number of the carrier and of whoever answers for vehicle safety.
How long do I keep Washington IRP mileage records?
- The department states two different periods on the same page, one in its recordkeeping section and a shorter one elsewhere. Keep to the longer of the two, and keep the trip-level detail rather than only the summaries, since audit adjustments follow from thin records.
