If you used a refund settlement product to help pay preparer fees, get your refund more quickly, or load your refund onto a direct debit card, your Economic Impact Payment (EIP) may have been directed to the bank account associated with those services.
The bank is required to reject the EIP if the associated account is closed or no longer active. Once that payment is returned to the IRS and processed, it will be delivered by mailed check to the most up-to-date physical address on file for you (this is pulled from either your 2019 or 2018 return, whichever is most recently filed, or the address on file with the U.S. Postal service).
Use the IRS Get My Payment tool to track your EIP. Note: An error has been corrected with the Get My Payment tool inaccurately reporting that rejected payments were being sent back to the same account a second time.
