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. 


Individual Income Tax | Payment with Return Filing



Once you have completed your individual income tax return, you may pay any tax owed using one of these methods.


Online Payment in Revenue Online

If you are using Revenue Online to file your return, you may choose credit card or e-Check payment or you may register in advance for Electronic Funds Transfer (EFT). For either method, you will process your payment through Revenue Online.

Check or Money Order

If you owe, you filed online or with tax software, and want to pay by check or money order, use the Individual Income Tax Payment Voucher (DR 0900) and follow these tips.

  • Make the check or money order payable to the Colorado Department of Revenue.
  • A check should never be sent to the Department of Revenue without a voucher form.
  • Do not send a copy of the return.
  • Write your Social Security number, the tax year and the words 'Form 104' on the check.

If you used a paper return, follow the tips listed above, mail the paper return (no voucher) but DO NOT staple the check to your paper return.
