Alternative Fuel Tax

The state road tax for vehicles that operate on propane (liquefied petroleum gas or LPG) is paid through the purchase of an annual flat fee sticker, and the amount is based on the vehicle's gross vehicle weight rating. Each person owning and/or operating a vehicle that operates on propane must obtain a decal annually from the Alabama LPG Board. The decal must be affixed to the vehicle according to LPG Board specification as proof that the issuance fee and decal fee have been paid. Vehicle owners must apply for a decal within 10 days of converting a vehicle to operate on propane or natural gas, or a 20% penalty will be applied to the decal fee. Out-of-state alternative fuel vehicle operators that purchase propane within the state must pay the current Alabama motor fuel tax or they may elect to purchase the annual flat fee decal. The propane dealer or supplier must remit these funds to the LPG Board before the 20th of the month following the date of sale. Decal and road tax requirements for natural gas fuels are suspended until October 1, 2018.

Alternative Fuel Tax

The excise tax imposed on compressed natural gas (CNG), liquefied natural gas (LNG), and propane used to operate a vehicle can be paid through an annual flat rate sticker tax based on the following vehicle weights:

Alternatively, owners and operators may pay an excise tax on CNG of $0.0887 per gasoline gallon equivalent (GGE) measured at standard pressure and temperature, $0.1017 for each diesel gallon equivalent (DGE) of LNG, and $0.06 per gallon of propane. One GGE is equal to 5.66 lbs. of CNG and one DGE is equal to 6.06 lbs. of LNG. The excise tax on ethanol and methanol fuel blends containing up to 15% gasoline or diesel fuel is one-half the tax on gasoline and diesel prescribed by California Revenue and Taxation Code section 8651.

(Reference California Revenue and Taxation Code 8651-8651.8, and California Business and Professions Code 13404 and 13470)

Gasoline and Diesel Gallon Equivalent Definition

Motor fuels, including alternative fuels, may be sold by gasoline gallon equivalent (GGE) or diesel gallon equivalent (DGE) as long as the dispenser used for the sale of motor fuel in GGEs or DGEs clearly displays the applicable conversion factor and other required information. (Reference Colorado Revised Statutes 8-20-232.5)

Alternative Fuel Excise Tax

Distributors who sell or use motor fuel, including special fuels, are subject to an excise tax of $0.26 per gallon. Motor fuels that are not commonly sold or measured by the gallon and are used in motor vehicles on public highways are taxed according to their gasoline gallon equivalent (GGE). The Georgia Department of Revenue may adjust tax rates annually based on vehicle fuel economy and the Consumer Price Index through July 1, 2018. A GGE of compressed natural gas (CNG) must be at least 110,000 British thermal units and a GGE of liquefied natural gas (LNG) must be at least 6.06 pounds. CNG is defined as a mixture of hydrocarbon gases and vapors, consisting principally of methane in gaseous form that has been compressed for use as a motor fuel. LNG is defined as methane or natural gas in the form of a cryogenic or refrigerated liquid for use as a motor fuel. Propane and special fuels sold in bulk to a licensed consumer distributor are exempt from this tax. The Georgia Department of Revenue may assess, levy, and collect tax for any other motor fuels used on public highways using a GGE rate. (Reference Georgia Code 48-9-1 and 48-9-3)

Propane Vehicle Decals

An individual may place propane into the fuel tank of a motor vehicle only if the vehicle has a valid alternative fuel decal affixed to the front windshield or the individual has submitted an application for a decal within the last 30 days. The cost of the decal varies according to vehicle type and the gross vehicle weight rating. The annual fee may be prorated if the vehicle is newly purchased, registered in Indiana, or converted to operate using an alternative fuel. For propane vehicles registered outside of Indiana, owners must purchase a temporary trip permit from a licensed propane dealer. For more information, see the Indiana Department of Revenue Fuel Tax Forms website. (Reference Indiana Code 6-6-14, 6-6-2.5-22, and 6-6-2.5-67)

Alternative Fuel Vehicle (AFV) Annual Fee

Owners of natural gas vehicles (NGVs) and propane 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:

To determine the actual annual license fee imposed per registration year, multiply the appropriate dollar amount given in the above schedule by the motor vehicle fuel tax rate in cents per gallon effective on July 1 of the preceding calendar year, and divide the resulting amount by $0.12. There is an additional $5 handling fee for each license issued.

The Washington State Department of Transportation (WSDOT) convened a work group and submitted recommendations to the legislature on an annual license fee that more closely represents the average fuel consumption of vehicles by weight. The work group also developed a transition plan to move more NGVs from the license fee to the fuel tax under Revised Code of Washington 82.38.030. The transition plan incorporates stakeholder feedback and includes draft legislation and cost and revenue estimates. The work group includes representatives from WSDOT, the trucking industry, NGV manufacturers, and other stakeholders. For more information, see WDOT's Annual License Fee in Lieu of Fuel Tax and Natural Gas Recommendations reports.
