Electronic Funds Transfer

The Colorado Department of Revenue offers an Electronic Funds Transfer (EFT) tax payment service. You may use EFT to pay more than 50 types of business and personal tax liabilities. For a complete list of accepted tax liabilities, see the DR 5785.  Colorado’s EFT program offers two choices: ACH Debit and ACH Credit. You may choose either or both. Both options are free, but first, you must be registered with the department to use either service.
If you have already registered for EFT and are familiar with it, visit the EFT Payment Website:

Automated Clearing House (ACH) Credit
When you contact your bank and ask them to "push" the payment to the Department of Revenue, this is ACH Credit. ACH Credit is similar to "Bill Pay" services offered by banks to their customers.
  • To use ACH Credit you will need to register the tax types you wish to pay by Electronic Funds Transfer (EFT) with the Department of Revenue. You can sign up for EFT through your Revenue Online account or by using the DR 5785.

Automated Clearing House (ACH) Credit
To make a payment, you will contact your financial institution to initiate an ACH credit to the Department of Revenue’s bank account. Make sure your financial institution is able to create a TXP record, which is a national banking standard. If our payment does not contain a TXP record or is incorrect, your payment will be returned to you as unprocessed.
