Our simple guide to “What documents do I need to file my Colorado state and federal income taxes?”
We have created a general guide for you to walk through when you’re gathering documents for your taxes. We kept this as a clean checklist with short notes so you can gather everything in one sitting. You can also have digital copies of the files if that is easier. If something on the list does not apply to you, skip it. The goal is to make tax time calm and clear.
