Check with your financial institution today.
Contact your financial institution to determine whether there is an active Automated Clearing House (ACH) Debit Block on the account(s) you are using to process business tax payments through MTO. With the transition to Paymentus, the Company ID that is used to identify JP Morgan Chase as the financial institution processing a payment on behalf of Treasury through MTO is changing to 0000408976. This Company ID must be updated by April 13, 2024.

What is an ACH Debit Block?
An ACH Debit Block prevents all electronic transactions from processing unless they are specifically authorized.

What is a Company ID?
For bank accounts with an ACH Debit Block, the Company ID is a password that allows an electronic payment to be processed.

How do I know if my bank account has an active ACH Debit Block?
Typically, the bank account owner enters into an agreement with the financial institution to place the debit block. If you are unsure, ask your financial institution.

What should I do if my bank account has an ACH Debit Block?
It is your responsibility to inform your financial institution that on April 13, 2024, the Company ID associated with MTO payments will change to 0000408976. If you do not, your electronic payment may be rejected and could result in fees, penalties, and interest.

How long does it take to update a Company ID?
Normally, it takes financial institutions 3 to 5 business days to process a Company ID change.

Is the new Company ID only for MTO tax payments?
No. Treasury electronic payment platforms are systematically transitioning to Paymentus. If you make electronic payments with Treasury for city of Detroit or individual income taxes, you will use the same updated Company ID number. All other Company ID numbers used by Treasury remain unchanged at this time.

What should I do if my bank account does not have an ACH Debit Block?
No further action needs to be taken.

Where can I learn more about making electronic payments with Treasury?

What’s next?
You can expect another message from us in two weeks with an announcement about MTO availability as we approach Paymentus implementation.
