My stimulus check and my federal tax return was deposited to a closed bank account what do I do?

If your refund and/or stimulus went to a closed bank account they go back to the IRS.  Then the IRS issues and mails a paper check to the address you used on your tax return.

If the account was closed before the deposits then the bank would have refused the deposits and sent the money back to the IRS and then the IRS will convert them to paper checks mailed to the address on the return.
