How to File Biodiesel Sold as Fuel But Not Used tax online

Recap on Biodiesel Sold as Fuel But Not Used

When biodiesel or renewable diesel is sold or used for purposes other than as a fuel after claiming a related tax credit, it becomes subject to a recapture tax under IRS No. 117. This applies when the fuel is not used in a qualifying way or is removed from a mixture. The tax must be reported on Form 720 at a rate of $1.00 per gallon, with an additional $0.10 per gallon if it includes a small agri-biodiesel producer credit. The amount is reported quarterly on Form 720, and no semi-monthly deposits are required.
