What are the tax incentives for biodiesel?
A federal tax credit for biodiesel was included as part of the American Jobs Creation Act of 2004. This tax credit equates to a one-penny per percent of biodiesel in a fuel blend made from agricultural products (such as vegetable oils like soybean oil) and 1/2-penny per percent of recycled oils (such as used cooking oils from restaurants). This incentive is taken by the petroleum distributors and passed on to the end users. There are more than 1,500 fuel distributors carrying biodiesel, and more than 600 retail pumps selling it. “The federal biodiesel tax incentive is helping build up the industry infrastructure, which leads to easier, more cost-effective access.” In July 2005, the U.S. Congress extended the biodiesel tax incentive, set to expire this year, to 2008," says Amber Pearson, National Biodiesel Board spokes woman.
