Sales Taxes on Natural Gas

Fuel subject to special fuel tax because it is used to operate a motor vehicle on public roads is exempt from sales tax. Fuel suppliers who purchase natural gas intended to operate a vehicle can give form TC-721CNG, Exemption Certificate for Compressed Natural Gas, to the fuel supplier. This certificate exempts all natural gas purchases from sales and municipal energy tax at the time of purchase.

Note: Buyers must have a fuel tax account, sales and use tax account, and a municipal energy sales and use tax account to report:

• Special fuel taxes for natural gas used as a fuel on road
• Sales and use tax for residential and commercial uses of natural gas
• Municipal energy sales and use tax for natural gas not used as a fuel on road
