Under the IRP, trucking companies register their commercial vehicles in Washington but can legally operate in all participating U.S. states and Canadian provinces. Registration fees are distributed among jurisdictions based on the percentage of miles driven in each, ensuring fair revenue sharing while reducing paperwork for carriers.
The IFTA further streamlines operations by allowing carriers to file a single quarterly fuel tax report through the Washington State Department of Licensing (DOL). This report accounts for fuel purchased and miles traveled in each jurisdiction, ensuring accurate tax payments and credits without the need for multiple state filings.
Together, the IRP and IFTA make cross-border trucking more efficient, helping Washington-based carriers operate seamlessly across North America while maintaining compliance with both state and federal requirements.
