To encourage the use of nonpolluting fuels, owners of compressed natural gas and liquefied petroleum gas powered vehicles are required to pay an annual license fee, based on gross vehicle weight rating (GVWR), instead of motor fuel excise taxes. The fee is calculated as follows:
| GVWR | Fee |
|---|---|
| Less than 10,000 pounds (lbs.) | $45 |
| 10,001 - 18,000 lbs. | $80 |
| 18,001 - 28,000 lbs. | $110 |
| 28,001 - 36,000 lbs. | $150 |
| More than 36,000 lbs. | $250 |
To determine the actual annual license fee imposed by this section for a registration year, the appropriate dollar amount given in the above schedule must be multiplied by the motor vehicle fuel tax rate in cents per gallon (as established by Revised Code of Washington 82.36.025) effective on July 1 of the preceding calendar year, and the resulting amount be divided by $0.12. In addition, there is a $5 handling fee for each license issued.
