Effective Sept. 1, 2013, a tax on Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) is imposed when the fuel is sold or delivered into a motor vehicle’s fuel supply tank by a licensed CNG/LNG dealer. A person who delivers CNG or LNG from their own storage into their own vehicles is also required to be licensed as a CNG-LNG dealer. Vehicles that operate using CNG or LNG will no longer prepay the CNG or LNG tax by purchasing a decal. (Tax Code Sec. 162.357) (Tax Code Sec. 162.352) IFTA
