Kentucky Form 10A070, officially titled “Authorization Agreement for Electronic Funds Transfer,” is used to request permission from the Kentucky Department of Revenue to make certain state tax payments electronically through the Automated Clearing House, or ACH, credit method. With an ACH credit payment, the taxpayer initiates the transaction through the taxpayer’s own bank and instructs the bank to transfer the payment to the Department of Revenue’s account. The form may be submitted when establishing a new electronic funds transfer account or when updating the contact name or address connected with an existing account. It collects identifying and contact information for the taxpayer and, when applicable, the bulk tax filer responsible for transmitting payments. It also requires the taxpayer to identify each tax account that will be paid electronically by entering the tax type code, Kentucky identification number, business name, and Federal Employer Identification Number. By selecting the ACH credit option and signing the authorization, the taxpayer asks the Department of Revenue to approve ACH credit transactions for the listed tax types. The taxpayer also acknowledges that each payment must follow the NACHA CCD+ format and include the required TXP payment information. Incorrect or incomplete payment data may prevent the Department of Revenue from matching the payment to the proper tax account and can delay the posting of the credit. Form 10A070 authorizes the payment arrangement, but it does not serve as the tax return or the electronic tax payment itself.

Tax Type Code
Enter the correct code for the tax being paid electronically.
The tax type code identifies the kind of Kentucky tax connected with the payment. Use the code provided in the taxpayer’s Department of Revenue records or electronic payment instructions.
Do not guess the code. An incorrect tax type code may direct the payment information to the wrong tax category.

Enter the Kentucky identification number associated with the tax type entered in the same row.
Use the account number assigned by the Kentucky Department of Revenue. Confirm that the number belongs to both the listed business and the listed tax type.

The name should match the Department of Revenue’s account records. When several tax accounts belong to the same business, repeat the business name on each applicable row.

When the taxpayer has fewer than four applicable tax accounts, leave the unused rows blank.
ACH Credit Selection
ACH Credit—Taxpayer Initiates Through Own Bank
Check this box to confirm that the taxpayer is requesting the ACH credit payment method.
Under this method, the taxpayer gives payment instructions to its own bank. The bank then sends the tax payment and the required identifying information to the Kentucky Department of Revenue’s bank account.
Do not select this option unless the taxpayer intends to initiate payments through its financial institution.
Authorization Agreement
The paragraph below the ACH credit checkbox explains the authority being requested and the taxpayer’s responsibilities.
Request For ACH Credit Authority
By signing the form, the authorized representative asks the Department of Revenue to permit the named taxpayer to initiate ACH credit transactions to the Department’s bank account.
The authorization applies to the taxpayer identified in the taxpayer-information section.
NACHA CCD+ Format Requirement
The taxpayer acknowledges that ACH credit transactions must be transmitted in the NACHA CCD+ format.
The taxpayer should coordinate with its bank or payment provider to ensure that the transaction is created in the required format.
TXP Convention Requirement
The payment must include the appropriate TXP convention information.
TXP information allows the Department of Revenue to identify important payment details, such as the taxpayer, tax account, tax type, and payment period.
Before making a payment, confirm that the bank can transmit the required TXP data with the ACH credit transaction.
Limitation To Listed Tax Types
The authorization applies only to the tax types entered in the “Taxes to be paid using EFT” section.
Do not use the authorization for a tax type that has not been listed and approved. Add each applicable tax type as a separate entry.
Consequences Of Missing Or Incorrect TXP Information
The taxpayer accepts responsibility for including suitable TXP information with every payment.
When the required data is missing, incomplete, or incorrectly formatted, the Department of Revenue may be unable to apply the money promptly to the correct account. This can delay the proper posting of the payment credit.
Signature And Date
Authorized Signature
An individual with authority to act for the taxpayer must sign on the signature line.
The signer should review the entire form before signing. The signature confirms the request for ACH credit authority and the taxpayer’s understanding of the transaction requirements.
An unsigned form may be considered incomplete.
Date
Enter the date on which the authorized representative signs the form.
Use a complete date that clearly shows the month, day, and year. Do not enter a tax period or payment date unless it is also the actual signing date.

Common Form 10A070 Mistakes To Avoid
Selecting The Wrong Submission Reason
Do not check “New EFT account” when you are only updating an existing account’s contact information. Select the option that accurately describes the request.
Leaving The ACH Credit Box Unchecked
The form is specifically requesting ACH credit authority. Failing to select the ACH credit option may leave the taxpayer’s requested payment method unclear.
Entering An Incorrect Tax Type Code
The tax type code determines which tax category is associated with the payment. Confirm the code instead of estimating or using an unrelated account code.
Mixing Account Information Across Rows
Every row must contain information for one tax type or tax account. Do not enter one account’s Kentucky ID number beside another account’s tax type code.
Omitting TXP Payment Information
Authorization alone does not guarantee that future payments will post correctly. Each ACH credit transaction must include properly formatted TXP information.
Using An Unmatched Business Name Or FEIN
The business name, Kentucky identification number, and FEIN should refer to the same taxpayer account.
Completing The Bulk Filer Section Unnecessarily
Complete the bulk tax filer section only when a bulk filer is involved in transmitting payments for the taxpayer.
Forgetting The Signature Or Date
Reviewing or typing information into the form does not replace the authorized signature. Sign and date the form before submission.
