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. 


Business Income Tax Installment Agreements



Understand your agreement and avoid default:

  • Sign and return a copy of the installment agreement,
  • Your future refunds will be applied to your tax debt until it is paid in full,
  • Pay at least your minimum monthly payment when it is due (we recommend remitting 2 days in advance if using Revenue Online or 10 days in advance if remitting by mail),
  • Remit your payment with the voucher that is mailed to you each month,
  • File all required tax returns and pay all taxes in full and on time or contact us to change your existing agreement if you cannot pay the balance in full,
  • Make all scheduled payments on time even if we apply your refund to your account balance, and
  • If you move, ensure that your mailing address is updated with the Department of Revenue.
