Revenue Online

  • Streamlining filing processes to simplify filing taxes for many tax types
  • Adding new functionality like search and help features
  • Enhancing the user experience so that the portal is easier to use
  • Making Revenue Online mobile responsive, so that it can be viewed on most devices

Note: SUTS

SUTS allows you to file with all state-collected jurisdictions and all participating home-rule jurisdictions. More home-rule cities are working on participating; eventually all will likely participate.
