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. 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 Web site:
