The Colorado Department of Revenue website indicates only that "The Department of Revenue is working diligently to start processing 2023 income tax returns. Please check back on February 15 for updated information."

It's unknown at this time when you'll be able to electronically file your Colorado tax return.

That said, you'll most likely be able e-file your Colorado tax return prior to that date. The revenue department will be able to hold your state return until the it's ready to start accepting returns.

Try submitting it now and then to see when it transmits.
