DR 5782 (11/30/21)

                    Colorado Department of Revenue Electronic 
                  Funds Transferred (EFT) Program For Tax Payments

The Colorado Department of Revenue requires all organizations filing fuel, cigarette or tobacco taxes, retail marijuana sales 
and excise taxes, withholding of income from an oil and gas interest, employers with annual wage withholding liabilities 
greater than $50,000.00, and businesses with annual state sales tax liabilities greater than $75,000.00 to pay through 
Electronic Funds Transfer (EFT). Other individuals and organizations may also choose to pay electronically. Electronic 
payments offer you a number of benefits:
•  The cost and time to write checks is eliminated.
•  You know exactly when your account will be debited.
•  You are assured that the funds are received on time, every time.
•  You may also register to pay other taxes electronically. For all taxes except wage withholding, estimated income, income, 
 income extensions, estimated severance and PUC fixed utility fees you will still need to file a tax return. 
•  You must file a complete sales and use tax return at the same time you make a sales/use tax payment.

Electronic Payment Options
Colorado's Electronic Funds Transfer program offers two methods of electronic payment:
•  Automated Clearing House Debit (ACH debit), Web payment and telephone options.
•  Automated Clearing House Credit (ACH credit).

Automated Clearing House Debit
To remit taxes via ACH debit e-check, access our Web site or place a call to a toll-free number. Both processes will prompt 
you to enter seven pieces of information: your EFT identification number, your PIN (Personal Identification Number), tax 
type code, filing period ending date, dollar amount owed, the settlement/effective date, and your phone number. The 
systems, in return, provide a reference number as proof of payment. The funds are withdrawn from your account as soon 
as the following day. We offer payment warehousing which provides the opportunity to designate a payment date up to 
365 days in the future, allowing you to place your payment in advance of the due date and have your funds withdrawn on 
the specified date. The Department of Revenue pays for the transaction.
Our  Web  feature  allows  you  to  make  tax  payments,  access  your  phone  and  Web  payment  history,  change  your 
PIN,  and  add  or  change  banking  information  online  through  a  secured  Web  site.  Please  visit  our  Web  site  at 
www.colorado.gov/revenueonline/

Automated Clearing House Credit
To initiate an ACH credit, instruct your financial institution to transfer funds from your account to the Department of Revenue's 
depository account. 

ACH Credits for Paying Taxes 
The ACH credit must be formatted utilizing the tax payment (TXP) within the addenda record of a CCD+ application. The ACH 
credit must be initiated on, or before, the due date; the funds are transferred to be received the next day by the Department 
of Revenue. The TXP addenda convention has been provided in this guide. Your financial institution may charge you for the 
transaction. Since some financial institutions can not originate ACH transactions, please contact them for more information.

ACH Credits for Paying Third Party Payments (TPP)
The Third-Party Tax Payments (TPP) are those payments made by a third-party to a federal or state taxing agency on behalf 
of a taxpayer.  Examples of third-party payments are 1) payments from employers or financial institutions in response to tax 
agency levies to garnish employee wages or accounts for tax liability and 2) employee tax withholdings remitted by payroll 
service providers on behalf of employers. You will be able to work with your bank to send any transactions through them 
using the proper format.

                                                                                      (Continued on page 2)

How To Enroll
To participate in the EFT program (for ACH Debit and ACH Credit for Tax Payments), you must complete an "Authorization 
for Electronic Funds Transfer (EFT) for Tax Payments" Form (DR 5785). The form may be completed on the Web by email 
or a paper document can be submitted.

Advantages of enrolling via the Web include:

•  It only takes the system a few minutes to process your application. It will provide a message that will include your EFT 
 number(s).
•  If your are registering for ACH Debit, an e-mail containing your Personal Identification Number (PIN) will be sent to you 
 same day. You will be able to enter your banking information online and make a payment the following business day. 
•  If you are registering for ACH Credit, you will be provided with a letter online that contains State of Colorado Department of 
 Revenue bank information and file layout for ACH Credit. You will be able to work with your bank to send any transactions 
 through them using the proper format.

When completing the Authorization Agreement, indicate the appropriate tax type code(s) for your tax(es). Please note that 
registration in the program via the EFT authorization form is critical for:

•  Verification of the account numbers and tax liabilities listed on your authorization form.
•  Assignment of a unique EFT identification number. This is necessary for the Department of Revenue to properly credit 
 your tax account.

For paper applications, once processed, a letter will be sent providing instructions on how to make a payment. You should 
receive your EFT number(s) and PIN(s) within three weeks. Incomplete or illegible Authorization Agreements may be delayed 
or denied without notice.
