Alternative Fuel Tax
The excise tax imposed on compressed natural gas (CNG), liquefied natural gas (LNG), and liquefied petroleum gas (LPG or propane) used to operate a vehicle can be paid through an annual flat rate sticker tax based on the following vehicle weights:
| Unladen Weight | Fee |
|---|---|
| All passenger cars and other vehicles 4,000 pounds (lbs.) or less | $36 |
| More than 4,000 lbs. but less than 8,001 lbs. | $72 |
| More than 8,000 lbs. but less than 12,001 lbs. | $120 |
| 12,001 lbs. or more | $168 |
Alternatively, owners and operators may pay an excise tax on CNG of $0.07 per 100 cubic feet measured at standard pressure and temperature, $0.06 per gallon of LNG, and $0.06 per gallon of propane. The excise tax on ethanol and methanol fuel blends containing up to 15% gasoline or diesel fuel is half of the current tax on gasoline and diesel.
