@bmoye2 asked: "Why can't I file my Colorado state income tax return?"
The Colorado state forms are projected to be available for filing on 1/31/2024.
You may receive an email when your forms are ready. If not, you can use the link that says "this tool" in the FAQ below to get to the tool to follow your forms availability. When it becomes available, there will be a green checkmark in the table.
