Montana ACH Credit Payment Instructions for Withholding Tax

Getting Started

You must first register and receive your Account ID.  The Department of Revenue accepts state income tax withholding payments.  Most financial institutions already have an ACH credit program in place for their customers and they will help you register with our program. If your financial institution does not have an ACH credit program, please contact us and we will help them get started or give you information about our ACH debit program.

If you are not registered or have not confirmed your Account ID with the Montana Department of Revenue for ACH credit payment transactions, please complete and return the registration form.  You can mail, fax or e-mail the registration form (via the Internet) to us and we will register you for the program. Once we have confirmed your Account ID, just give this information to your bank.

Payment

When you wish to pay your state income tax withholding by ACH credit, you will instruct your bank electronically to withdraw funds from your account and transfer them to the Department of Revenue. You will be required to tell the bank the date you want funds to transfer.

Due Dates

It is your responsibility to be familiar with your particular bank's practices to ensure payment is posted to our bank account timely. We will assess penalties and interest if you make electronic payments late.

State Banking Information

The State of Montana has contracted with U.S. Bank for ACH services. Your financial institution will transfer funds from your account to our account in U.S. Bank. To ensure that the transaction is completed correctly, your financial institution will ask you where you want them to transfer your payments. The information below is critical to the ACH process. Please give all of the following information to your financial institution. You will need to follow your bank's instructions if you want to properly transfer money. U. S. Bank requires ACH credit transactions to follow standards developed by the National Automated Clearing House Association (NACHA).
