Pay with Your Debit or Credit Card
The Department can accept debit or credit card payments only if you have received a bill and only on Revenue Online. We cannot accept this method of payment over the phone or in our service centers. If you don’t have a bill, please see the topic “Pay Tax Due with Return Filing” for more information. Please have the following information ready:
When using Revenue Online to make a payment, you have the option of creating direct access to your account which will allow you to see data about your account. Or, you can simply enter all the relevant payment information after selecting Make a Payment. You can read help topics on Revenue Online by clicking "Help."
Pay Directly from Your Checking Account
You can pay your bill electronically with your checking account information using Revenue Online. We cannot accept this method over the phone, but you can remit a check through the mail or at one of our service centers. If you have not yet received a bill, please see the topic “Pay Tax due with Return Filing” for more information. Please have the following information ready:
Pay Using Electronic Funds Transfer
You must pre-register for this service, which can take several business days. If you are nearing your due date, please choose a different method of payment.
Mail Your Check or Money Order

If you choose to mail your tax payment:
The quickest and easiest way to make a tax payment is by Revenue Online. You can pay in cash only if you have received a bill and only at the Pierce Street Service Center.
If you choose to pay in cash:
If you are unable to pay your tax bill immediately, you may request a monthly installment agreement (payment plan). To apply for a monthly installment agreement, you must first have received a bill. To qualify, you must have filed all required tax returns and you cannot have an active bankruptcy. Installment agreements (payment plans) for business tax debt (such as sales tax and wage withholding) can only be requested by speaking with a Compliance Agent at 303-866-3711. Agents are available from 8 a.m. to 4:30 p.m. Monday through Friday.
Understand your agreement and avoid default:
Our agents will set your monthly payment amount in consideration of the total amount of tax debt owed. If you do not receive a payment voucher, remit your payment on Revenue Online and call the Colorado Department of Revenue Collections Section at the number listed above. Penalties and interest continue to accrue until your balance is paid in full. If you are in danger of defaulting on your installment agreement for any reason, contact us immediately.
