IFTA (International Fuel Tax Agreement) is an agreement between the 48 contiguous states and 10 Canadian provinces that allows motor carriers to report and pay fuel taxes for all the jurisdictions they travel in using a single fuel tax license and decals. IFTA Fuel Tax Reporting Service is a service that assists motor carriers in calculating, reporting, and paying their fuel taxes to the appropriate jurisdictions. It typically involves the use of software that helps carriers track their fuel consumption and miles traveled in each jurisdiction, and then generates the necessary reports and forms for filing with the IFTA. Some companies also offer additional services such as filing the reports on behalf of the carrier and providing support and guidance throughout the process.
