W-2 & 1099 Statements

W-2 Statements

When filing a paper return, all W-2s and/or 1099s that show Colorado income tax withholding must be stapled to the front of the form where indicated. When filing an electronic return, attach scanned copies of all W-2s and/or 1099s that show Colorado income tax withholding to the e-filed tax return. If you are unable to attach W-2s and/or 1099s to your e-filed return, submit through Revenue Online.
