Please remember that you must claim the state sales tax refund (TABOR refund) when filing your state income tax return. If you claimed a 2023 refund, the TABOR refund will be combined and issued out with your refund. Unlike the 2022 Colorado cashback, no separate check will be issued.

Fuel Tax Filing Information

Fuel Reporting for Colorado 

Every one who is required to obtain a Colorado fuel tax license must file monthly returns with the Department. Filing requirements apply to every distributor, supplier, carrier, exporter, importer, blender, refiner, and terminal operator. Each return must report all fuel acquired in, imported into, or removed from any terminal in Colorado, including all gasoline, aviation fuel, diesel, biodiesel, CNG, and LNG. Fuel blenders must also report all blend components for use with any of these fuels that they have on hand, acquired, or blend during the reporting period, whether it is for motor fuel use or off-road use. Certain special rules apply to the reporting of LPG.  

There are three different returns that are required based on your License.

  1. Fuel Terminal Operator Return - If you operate a Federal or State qualified Terminal, whether you own the fuel within the terminal or not.
  2. Fuel Carrier Return - If you are a commercial carrier, hauling fuel that you do not own.
  3. Fuel Distributor Tax Return - Fuel distributors must report all activity of fuel within the state.

Returns are due monthly on the 26th day of the month following the activity or the next business day if the 26th is on a weekend or holiday.

Recordkeeping Requirements: Colorado law requires fuel distributors, carriers, terminal operators, and any other licensee to keep true and complete records of their returns, receipts, disbursements, and activities for at least three years.

Using the above-gathered information and referencing the links for the reporting schedules, fuel codes, and modes, the filer will complete their return with all required information.

Fuel Distributors

Fuel distributors are required to report the original manifest of the terminal, which is part of that month’s available inventory. Fuel that is not disbursed to another entity within the same month, becomes part of that month’s ending inventory.   

All reporting is required through the Department's online filing system, Revenue Online. Distributors file form DR 7050 in their Fuel Excise Tax account, and have three ways in which they may enter the required information into the return:

  • Web Entry - Information is entered directly into Revenue Online
  • Excel Spreadsheet Upload - Download the most current template from our website, complete the spreadsheet, and upload it to Revenue Online. If Revenue Online does not accept the file because something is missing or incorrect, the file will need to be adjusted and re-uploaded.
  • XML Upload - This filing option is designed for large-scale reporting.

In general, excise taxes and fees are imposed on the distributor who first acquires the fuel, unless the fuel is tax-exempt. Please see Parts 1 and 3 in the Colorado Fuel Tax Guide for additional information about taxable fuels, exemptions, and distributors’ liability.

If excise tax has been paid on fuel that is exempt, the user may be able to claim a refund. Please see the Fuel Tax Refund web page and review the Fuel Tax Guidance Publications for important refund information. 

Special rules apply to the excise tax imposed on propane (LPG). Please see Appendix G of the Colorado Fuel Tax Guide for additional information.

Terminal Operators are required to report the fuel type, transportation method, carrier, position holder within the terminal, as well as the original document date. For example, the manifest number or railcar number if not received by pipeline. They must report a detailed schedule of inventories for each position holder within each Colorado terminal monthly. The schedule must include beginning and ending inventory, total receipts, and total disbursements for each position holder.
