Liquefied Petroleum Gas (LPG) Tax

For taxation purposes, LPG used as a motor vehicle fuel must be converted to a liquid gross gallon equivalent using the conversion factor of 4.24 pounds per gallon of liquid at 60 degrees Fahrenheit. LPG is taxed at a rate of $0.20 per GGE. (Reference South Dakota Statutes 10-47B-3 and 10-47B-4)

Liquefied Petroleum Gas (LPG) License

LPG may be exempt from the fuel excise tax when sold from a licensed LPG vendor to a licensed LPG user or an LPG vehicle owner if it is delivered into a bulk storage tank that can then be used to deliver fuel into a motor vehicle. LPG purchasers must obtain a propane user license before LPG is delivered into a storage tank. (Reference South Dakota Statutes 10-47B-167)
