No changes can be made to your return or account number once your return has been received.

• If the account number is not a valid number the financial institution will return the deposit to the Michigan Department of Treasury. The refund will be mailed to the address on your return.
• If it is a valid account number your financial institution may catch the error and deposit it into your account.  If the deposit goes into a valid account number as indicated on your return, but it is not your account, it is a matter for you and your financial institution to resolve.
