Sales tax filers with one or more locations/sites may file on Revenue Online, by XML (Extensible Markup Language) or through the new SUTS portal, which can also file most Home Rule Self Collected Cities in a single return.
A list of XML approved software vendors is available on the File Sales Tax Online webpage. Use of Department approved XML software does not require individual approval.
Filers with multiple locations/sites may file using the provided spreadsheet template, see the Sales Tax Spreadsheet Filing webpage. Use of the spreadsheet requires pre-approval by the Department. The SUTS portal does not require pre-approval, please see the SUTS Help webpage for more information on the SUTS system.
