Motor Vehicle Dealer

For purposes of the Oregon Motor Vehicle and Aircraft Fuel Dealer License Tax, motor vehicle fuel is mostly limited to gasoline and gasohol blends. It includes aviation gasoline and jet fuel. This definition also applies to Multnomah and Washington counties.


For purposes of the Motor Vehicle Fuel Dealer taxes for the cities of Portland, Troutdale, Reedsport, Woodburn, Eugene, Springfield, Cottage Grove, Veneta, Tigard, Milwaukie, Coquille, Astoria, Warrenton, Canby, Newport, and Hood River the definition of motor vehicle fuel expands to include gasoline, gasohol blends, and (highway) diesel fuel products.


Diesel fuel is not taxable as a motor vehicle fuel for the purposes of the Oregon Motor Vehicle Fuel Dealer License tax, nor is it taxable for Multnomah County, Washington County or City of Coburg. However, diesel fuel used on the highway is taxable by the State of Oregon under Oregon Use Fuel law.

Refer to the appropriate state, county, or city statute to confirm what fuels are included as motor vehicle fuels in a jurisdiction.

​Aircraft Fuel includes aviation gasoline and jet fuel. This fuel is taxable only for the purposes of the Oregon Motor Vehicle and Aircraft Fuel Dealer License Tax.

Pure or denatured ethanol is not taxable until it is blended with motor vehicle fuel for highway use.

There is no licensing requirement for sale, use and distribution of pure or denatured ethanol. Records of ethanol sales may be requested by the Fuels Tax Group.

Dealers who purchase pure or denatured ethanol to blend into motor vehicle fuel must be licensed and pay tax on the amount blended. Ethanol blended gasoline is taxed at $.30 cents per gallon. The same rules apply to county and city jurisdictions according to applicable county and city ordinances.

Contact the Oregon Department of Agriculture and the city of Portland for further information concerning ethanol requirements in Oregon.

 Use Fuel Seller

Use fuel is the general term used to refer to all other fuels besides gasoline, gasohol blends or aircraft fuels. Common examples include all types of diesel, biodiesel and natural gas products (CNG, propane, etc.). Specific fuel descriptions can be found in ORS 319.  
 
Refer to the appropriate state, county, or city statute to confirm what fuels are included as use fuels in a jurisdiction.
 

​Biodiesel refers to the pure fuel before blending with petroleum diesel fuel. Biodiesel blends are denoted as "BXX" with "XX" the percentage of biodiesel contained in the blend (i.e., B20 is 20% biodiesel, 80% petroleum diesel).
​​If propane is sold for use in a motor vehicle, a Use Fuel Seller License is required.
 
When reporting you must convert the taxable propane gallons to use fuel, by dividing the gallons sold by 1.3, then multiplying by the $0.30 tax rate.
 
Sales of propane into containers are not subject to the Oregon tax.
A seller sells use fuel to a user. Sale types include:
  • Bulk
  • Fleet
  • Cardlock
  • Retail
 
To see a full description of operations that classify you as a seller see our License Programs page.
 
To apply for a seller license, please go to our Oregon Fuels Tax System website. Tutorials with visuals are available under our Online Tutorial page.
 
​​When biodiesel is used to propel motor vehicles, the fuel becomes taxable as an Oregon Use Fuel under ORS 319.520(7).The rate is $0.30 per gallon, whether the fuel is pure biodiesel (B100) or mixed with petroleum based diesel products, regardless of the ratio.​
 

Diesel blended with at least 20 percent biodiesel that is derived from used cooking oil is not taxable per Oregon Revised Statute 319.530. This exemption applies to fuel sold between January 1, 2014 and December 31, 2019 and only applies to fuel:

  • Used in motor vehicles with a gross vehicle weight of 26,000 lbs or less.
  • That is sold in retail operations only.
  • That is not sold in seller operations involving cardlock, fleet fueling or bulk sales.
Accepting cardlock cards as a method of payment does not make you a nonretail (cardlock) seller. You are a retail seller.
 
You may not sell ex-tax just because the payment is via cardlock card. The method of payment (cash, credit card, cardlock card, etc.) does not matter whether or not the sale is taxable. For sales as ex-tax, the seller must document the ex-tax sale.
No. The seller should not include Extended Network Sales on their Fuels Tax Seller Report. The retailer reports and remits the tax to the Fuels Tax Group.
​​​To qualify as a non-retail seller, you must have an unattended facility accessible only by cardlock card. The unattended portion of a retail facility must be separate from the retail operations that is accessible only by cardlock card.
 
Keylock operations that cannot identify individual fueling are considered retail.
​A vehicle may receive use fuel exempt of the Oregon tax if the vehicle:
  • Has an ODOT weight receipt, temporary receipt, or temporary pass.
  • Has US Government plates, Oregon state government ‘E’ plates.
  • Has a valid Oregon use fuel User emblem.

All tax-exempt sales of use fuel must be documented with a tax-exempt invoice. 
A use fuel invoice must show at least the following (ORS 319.671)​:
  • The seller's name and address.
  • The complete date of sale (month, day, year).
  • The amount of the sale in gallons.
  • The name and address of the customer.
  • The credential as to why it is an ex-tax sale. Vehicle, equipment or container information including:
    • The ODOT weight receipt, temporary receipt, or temporary pass, if the vehicle is subject to weight-mile taxes.
    • The emblem number, if the vehicle bears a user´s emblem.
    • The U.S. government license plate number or Oregon state ‘E’ plate number if the vehicle bears no valid user's emblem or permit issued by the department.
    • A description of the container or equipment (can, slip tank, tractor, backhoe, etc.).
    • In cases where equipment is fueled from the same fuel tank as the motor vehicle, the pump must be stopped between the fueling of the motor vehicle and equipment. Document the purchases separately.
To sell use fuel exempt of the Oregon tax at a non-retail facility you must:
  • Have your customer complete and sign an exemption certificate.
  • Validate the credential based on the reason for exemption. For example, if reason 2 is selected, list the current year emblem numbers issued by the Fuels Tax Group for each vehicle.
  • Issue ex-tax cards by vehicle (plate number in description) or specific description of equipment or container (tractors, slip tank, etc.).

You are required to keep the Oregon Exemption Certificate on file. A signed certificate validates that the customer accepts all liability for any cards used. Your customer is responsible for keeping the certificate current and complete. If you do not have an Oregon Exemption Certificate on file, you are responsible for the tax on all of the customer's Oregon use fuel purchases.

NOTE: if your customer wants cards issued by employee, location or generic description (equipment, off road, etc.) those cards must be issued as taxed.

No. By law tax forgiveness only applies to gallons purchased at a retail station.

Biodiesel refiners must certify on their bills of lading the feedstock used to produce the fuel is in fact 100% used cooking oil and the location of the refinery. If the bill of lading does not include this certification, the tax cannot be forgiven on this fuel. ​
