When you e-file your return you will receive prompts to provide your routing transit number (RTN), account number, and account type (savings or checking). You do not need to mail in a paper copy of form 3174, Michigan Direct Deposit of Refund.
If you are filing a paper return, complete the direct deposit information on the MI-1040 and MI-1040CR tax return. You will need to provide your RTN, account number and account type (savings or checking). When filing an MI-1040CR-7 you must complete form 3174, Michigan Direct Deposit of Refund.
Routing Transit Number (RTN): The 9-digit RTN is usually found between the symbols |: and |: on the bottom left side of your check. The first two digits must be 01 through 12 or 21 through 32. If you have any questions check with your financial institution for this number.
Account Number: Enter your financial institution account number up to 17 characters (both numbers and letters). The account number is usually found immediately to the right of the RTN on the bottom of your check. Include hyphens but omit spaces and special symbols. Enter the number from left to right and leave unused boxes blank. Do not include the check number.
Account Type: Please specify as to whether the account you wish to have your refund deposited is a checking or savings account.
Note: Verify that all account and routing numbers are correct. Your routing transit number and account number cannot be changed or added after the return has been filed.
