For in-kind donations, submit an itemized list of the donated items and their fair market value. Submit using Revenue Online or include with your paper return. You only have to submit receipts if you are claiming donations greater than $5,000.
The Department strongly recommends that you submit these documents using the e-Filer Attachment option on the Revenue Online(opens in new window) website, which eliminates the requirement to mail this form. For more information see https://tax.colorado.gov/DR1778
