Software Developers | Fuel Tax XML

Tax software developers may use XML to transmit fuel tax returns beginning in the 2022 tax year. Before you begin using XML, be sure to review the Fuel Revenue Online XML Schema Guide. If you are a developer and have questions about XML filing, please email DOR_FuelTax@state.co.us.

Tax professionals and accountants who do not have software development experience are encouraged to use spreadsheet filing in lieu of XML filing. Visit the Fuel Tax Spreadsheet Filing web page to learn more.
