Aviation Taxes
Due to the passage of House Bill 22-1070, boundaries of special districts may or may not align with the boundaries of another special district, municipality, or county. As a result, form DR 1510 has been revised beginning with the January 2023 period to include more columns to separate out special district reporting.

Due to the passage of Senate Bill 22-006, effective January 1, 2023 through December 31, 2023, the state service fee is 5.3%. When net taxable sales are more than $100,000 for all sites, the state service fee is reduced by a state service fee addback which is calculated on the State Service Fee Worksheet, form DR 0103.

Aviation Fuel Excise Tax

Colorado imposes an excise tax on aviation gasoline and jet fuel acquired, offered for sale, sold, or used in this state. Excise fuel tax are due when removed from a terminal or imported into the state. The tax is calculated on gross gallons acquired. The tax rate for aviation gasoline is 6¢ per gallon. 

Aviation Fuel has an exemption from excise tax for sales to direct air carriers, and FAA Part 121 or 135 air carriers as defined in §39-27-101(6), §39-27-101(19) and §39-27-101(20), C.R.S. When reporting aviation fuel disbursements to a FAA Part 121 or Part 135 air carrier, fuel distributors must provide the airport destination in Column 4 of their Distributor Schedule of Disbursements Worksheet (DR 7050). The Federal Aviation Administration (FAA) airport code is used to report the destination airport.

Aviation Fuel Sales Tax

Colorado state and state-collected local sales tax is due on aviation jet fuel used in turbo-propeller or jet engine aircraft for all FAA Part 121 or 135 air carriers. 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 Aviation Fuel Tax Return (DR 1510). The entity who sells the fuel to the end user is responsible for remitting the aviation fuel sales tax. Only fuel is reported on the Aviation Fuel Sales Tax Return (DR 1510).

Due to the passage of Senate Bill 22-006 retailers with total net taxable sales of $100,000 or less for all sites are able to retain 5.3% of the state sales tax as compensation for the retailers expenses incurred in collecting and remitting the tax (the state service fee) for January 2023 through December 2023 filing periods. Retailers with total net taxable sales over $100,000, up to $1,000,000, are able to retain 4%, up to the maximum state service fee allowed of $1,000. Retailers with total net taxable sales over $1,000,000 are not able to retain the state service fee. The 5.3% state service fee is calculated on the return, form DR 1510. The reductions to the state service fee are calculated on the State Service Fee Worksheet, form DR 0103.  

The revenues generated from the state sales tax are transferred to the aviation fund as required by statute (§43-10-109(1) C.R.S.). Tires, motor oil, and other aviation items are reported on the Retail Sales Tax Return (DR 0100).

Applicable county, city, and other local jurisdictional taxes must be remitted on the Aviation Fuel Sales Tax Return, DR 1510 form. Scientific and Cultural Facilities District (SCFD) taxes are not dues on the sale of aviation fuel.

Flowage Fees

If sales or use tax is imposed on the sale, the fee is subject to state and/or jurisdictional taxes that apply to the sale. Jet fuel or gasoline used for aviation can be subject to a fuel flowage (in-plane) fee imposed by the airport. This fee is part of the retail purchase price.
