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.
