Indiana AVF-105

This guide provides comprehensive, step-by-step instructions for understanding, completing, and filing the aviation fuel tax exemption certificate.

Indiana Form AVF-105, officially titled the Aviation Fuel Excise Tax Exemption Certificate, is a critical financial document utilized by specific individuals and businesses to legally bypass the state excise tax on aviation fuel. When fuel is purchased with the strict intention of being placed directly into the supply tank of an aircraft, eligible buyers use this form to prove their tax-exempt status under state regulations. The document serves as a binding legal certification, signed under penalties of perjury, ensuring that the buyer meets the rigorous criteria required for tax-free purchases. Misusing this certificate, whether through intentional fraud or simple negligence, carries serious consequences, including the potential for heavy taxes, accumulated interest, and severe civil or criminal penalties levied against the individual or the represented business entity. By standardizing this exemption process, the state revenue department ensures that only qualified entities—such as government agencies, common carriers, and certified agricultural operators—benefit from the financial relief.​

How To File Indiana Form AVF-105?

Unlike traditional tax returns, you do not mail this completed certificate directly to the state revenue department. Instead, you must present the finalized form directly to the vendor or seller from whom you are purchasing the aviation fuel. The seller is legally required to keep this exemption certificate securely on file to validate and support the tax-exempt sale during any future audits. If you are an out-of-state buyer, be aware that the state retains the right to verify your registration status independently after the transaction.​
