Fuel Taxes and Fees
Gasoline and gasohol motor fuel taxes
are due when acquired from a terminal and removed for distribution. Three tax-deferred transactions are allowed between Colorado licensed distributors after the fuel has left the terminal of origin. No more than three tax-deferred transactions are allowed. The tax is calculated on gross gallons acquired. The tax rate is 22 cents per gallon.
Aviation fuel taxes (gasoline and jet)
are due when acquired and removed from the terminal rack. Three tax-deferred transactions are allowed between Colorado licensed distributors. The tax rate for aviation gasoline is 6 cents per gallon. The tax rate for aviation jet fuel is 4 cents per gallon. When reporting aviation fuel disbursements, you must provide the airport destination in Column 4
Distributor Schedule of Disbursements Worksheet (DR 7056)
. The Federal Aviation Administration airport code is used to report the destination airport.
The special fuel excise tax
is due when acquired from a terminal and removed for distribution. Three tax-deferred transactions are allowed between Colorado licensed distributors. The tax is due on gross gallons acquired. The rate is 20.5 cents per gallon for all special fuels with the exception of liquefied petroleum gas (LPG), liquefied natural gas (LNG) and compressed natural gas (CNG). These fuels are taxed at a separate rate that will change annually from January 1, 2014 through 2019.
For more information on the rate schedule, see Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG) and Fuel Rates further down on this page.
The Environmental Response Surcharge (ERS)
is due from all distributors who report the acquisition of fuel in Colorado. The rate fluctuates based on revenue in the Petroleum Storage Tank Fund. The ERS must be included on all fuel sold in Colorado, with the exception of: aviation fuel, fuel exported out of Colorado, fuel sold to railroads for off road use, or any fuel subject to the LPG/Natural Gas Fee.
The Liquefied Petroleum Gas and Natural Gas Inspection Fee
is imposed on purchases of LPG, LNG, CNG and collected by distributors of liquefied petroleum gas (LPG), liquefied natural gas (LNG) and compressed natural gas (CNG) in Colorado.
When reporting the acquisition of gasoline and special fuel and determining the amount of excise tax due, Colorado law provides for a 2 (two) percent allowance of the total amount of fuel to be deducted by the licensed distributor. The 2 percent allowance covers any losses in transit and in unloading the fuel and costs of collection. Out of this allowance, the licensed distributor shall make to each retailer an allowance of one percent of the amount of gasoline or special fuel delivered during each calendar month as shown by delivery invoices signed by the retailer.
Sales Tax on Aviation Jet Fuel
Colorado state and state-collected local sales tax is due on aviation jet fuel used in turbo-propeller or jet engine aircraft. Sales tax is charged on the purchase price of the fuel. The purchase price may include the cost of fuel, state and federal excise taxes, and any airport fuel flowage fees.
The amount of aviation jet fuel sold (retail sales) is reported when the retailer/distributor files their Colorado Aviation Fuel Tax Return and Reporting Form. Retail sales tax filers will report on the
Aviation Fuel Sales Tax Return (DR 1510)
Only Colorado fuel licensees (distributor, supplier, blender, or importer) responsible for the collection of the excise tax can sell fuel, which is exempt from the Colorado fuel excise tax, to users.
Gasoline can only be sold without excise tax to government entities.
The gasoline must be requisitioned and used by the government entity and paid for with funds drawn from the government entity. Government entities must apply for and receive an exemption certificate from the Colorado Department of Revenue before they can purchase fuel tax exempt. Government entities can apply for an exemption certificate by completing the
Application for Fuel Tax Exemption Certificate for Government or Political Subdivision (DR 0241)
. Upon receipt of an exemption certificate, such governmental entity may purchase gasoline or special fuel from a distributor without payment of the excise tax imposed pursuant to statute if the gasoline or special fuel is used exclusively by the governmental entity in performing its governmental functions and activities.
Special fuel can be sold without excise tax to government entities
, and the same guidelines as gasoline apply. All other sales of clear diesel fuel must include the excise tax. If purchasers feel they have an exempt use of the fuel, they can apply to the Department of Revenue for a refund.
Dyed diesel fuel
is sold without excise tax to be used for exempt purposes off road such as agricultural, home heating, or commercial manufacturing. Dyed diesel is not exempt from the Environmental Response Surcharge fee.

Liquefied Petroleum Gas (LPG)/ Propane
used to propel a motor vehicle on Colorado highways must be sold with the excise tax included. LPG/ Propane can be sold without excise tax to an end user for use in a home heating system or other non-vehicle uses. The fee for
Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG)
must be included on all sales of LPG, LNG and CNG. The fee has the same exemptions as the Environmental Response Surcharge.
All other deliveries and sales of fuel must include the excise tax
and be reported as such when filing the Colorado Fuel Distributor Tax Return. If purchasers are using excise tax paid fuel for purposes exempt by statute, they can apply to the Colorado Department of Revenue for a refund permit to receive a refund of the excise tax paid. See Other Fuel Taxes | Refund.
