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. 


Amending a Withholding Return


If you are unable to claim the credit on a subsequent e-file or paper return within the calendar year, you should claim a refund on your Annual Transmittal for the appropriate year:

If you owe additional tax, file another return for the period the tax is due reporting only the additional amount owed through Revenue Online. If you cannot file electronically, file the appropriate paper return reporting only the additional tax due for the period.
