Washington’s prorate program migrated systems in early 2025: the Taxpayer Access Point that older guides describe is gone, replaced by License Express, and former TAP users had to actively transfer their accounts. The program itself — who registers, what documents travel with the application — carried over intact.
Accounts and applications
IRP applies to commercial vehicles over 26,000 pounds GVW running two or more jurisdictions, vehicles with three or more axles at any weight, qualifying combinations, and Washington-titled vehicles operating interstate. A new account files the IRP Application (Form 450011) with the Established Place of Business form, current Washington registrations matching the account name exactly, USDOT numbers, lease paperwork where applicable — and the federal Heavy Vehicle Use Tax form (2290) showing current tax payment. Submit through License Express, by mail to Motor Carrier Services, or in person at a prorate and fuel tax office.
Renewal notices mail 90 days before your account-specific expiration, and the renewal runs through License Express — with invoices appearing in your account letters within about 24 business hours.
The 2290 rules — including the filename quirk
At IRP renewal, Washington requires a current stamped copy of the Form 2290 for all vehicles running a combination of 55,000 pounds gross vehicle weight or more with a purchase date of 60 days or more ago — the 60-day carve-out for new purchases is written right into the requirement. For intrastate heavy trucks renewing tabs, the DOL accepts the validated Schedule 1 for the current period, a receipted Schedule 1 showing proof of filing, or the 2290 plus Schedule 1 with the front and back of the cancelled check, and it recognizes the 5,000-mile (7,500 agricultural) suspension categories.
The upload rule that stalls renewals: License Express will not accept multiple files with the same name. Uploading Schedule 1s for several vehicles means renaming each file on your computer first — truck101-2290.pdf, truck102-2290.pdf — before the system will take them.
