How to obtain copies of tax returns from the Colorado Department of Revenue

Sign up for account access through Revenue Online and get copies of tax returns (paper or e-filed). Revenue Online is a secure method of accessing tax account history and information. 

Here is what is available in Revenue Online (as long as the return was filed with the Colorado Department of Revenue, either on paper or electronically):

  • Individual income tax returns going back to 2009.
  • Corporate, fiduciary and partnership income tax returns going back to 2010.
  • Sales tax, retailer’s use tax and withholding tax returns going back to 2010.

Copies may be printed from Revenue Online as long as the taxpayer (or a representative of the taxpayer) has signed up for Revenue Online access to the specific tax and is logged into the account.

To obtain paper copies of tax returns by mail, complete and submit the Request for Copy of Tax Returns (DR 5714). A third party who has a valid state or federal Power of Attorney may request return copies by attaching the Power of Attorney (DR 0145) or the federal 2848 power of attorney form to the DR 5714. The Power of Attorney document must specify the tax types the third party can access. Note that to ensure tax information confidentiality, the Request for Copy of Tax Returns requires notary verification on the paper form regarding the identity of the individual making the request, even when the taxpayer (not a third party) is making the request.
