Please remember that you must claim the state sales tax refund (TABOR refund) when filing your state income tax return. If you claimed a 2023 refund, the TABOR refund will be combined and issued out with your refund. Unlike the 2022 Colorado cashback, no separate check will be issued. 


No Withholding Tax Collected


When filing a zero return through Revenue Online you will first need to request a Letter ID number to be mailed to the address we have on your account. If you are not able to file online, you can file by paper using the Income Tax Withholding Return (DR 1094).

Note: After 12 months of consecutive filing of zero returns, you will receive a letter notifying you that your account should be renewed or the withholding account should be closed.
