International Fuel Tax Agreement forms include IFTA permit applications and diesel fuel schedules, as the Ohio Department of Taxation lists. States typically provide their own IFTA forms through their tax departments.
Other IFTA forms are the IFTA tax return itself, the carrier application for license and decal, and the renewal application, according to the North Carolina Department of Revenue. Also provided are instructions for completing or amending the IFTA tax return. State departments of taxation usually offer IFTA tax rates going back several years, notices about IFTA rate changes and credentials, general information about the IFTA, and the ability to file IFTA taxes electronically.
