How to File

You can file your Colorado taxes electronically

Each year, thousands of paper tax returns contain errors or missing documentation that may delay your refund. The Colorado Department of Revenue offers FREE, convenient and secure electronic filing services which are available 24-hours a day, every day throughout the income tax season to file your state income tax returns. This convenient, accurate and secure electronic filing system not only saves time but helps to process your filing faster. And if you're expecting a refund, speed is important. We also encourage taxpayers to complete a Colorado 104 Individual Income Tax form prior to using this system. It will make the process go faster.

 

There are many other electronic filing websites and tax software that can be used to file Colorado income tax returns, but some are not free.  It’s up to you to choose the method of electronic payment you want to use, but all methods will help ensure the return is free of math errors.  That’s one of the benefits of electronic filing.  A clean return helps with a faster refund.

 

Revenue Online

Colorado Revenue Online is a web-based system that is quick and easy to use. Once you have completed your federal income tax return you can log into www.colorado.gov/revenueonline  to file your state return. The system guides users through the form line-by-line and corrects math errors as you go along.

Before you complete your e-file return the Colorado Department of Revenue offers one more method to receive your refund check faster and safer.
