Is Dilbit Oil? Congress and the IRS Say No

The oil industry has often said that dilbit, a heavy crude oil from Canada’s tar sands, isn’t much different from conventional crude oil. But when it comes to paying into a federal fund used to clean up oil spills, it’s different enough to deserve a sizeable tax break.

Dilbit is exempt from the tax, because the 1980 legislation that created the tax states that “the term crude oil does not include synthetic petroleum, e.g., shale oil, liquids from coal, tar sands, or biomass…” This position was upheld in an 2011 IRS-issued Technical Advice Memorandum.
