Fiduciary Income Tax | File Online

You can file your Fiduciary Income Tax Return online through Revenue Online. However, if you are a first-time Colorado income tax filer, you must file a paper return or through an accepted tax software program. After your first tax return is processed, you may create your own User ID and Password to use in Revenue Online. For more information, review the instructions in How to Create a Login and Access to Revenue Online, the E-Filer Handbook, or visit the Revenue Online How-To web page.
