Per the IRS:
I requested a direct deposit refund. Why are you mailing it to me as a paper check?
There are three possible reasons. They are as follows:
- We can only deposit refunds electronically into accounts in your own name, your spouse's name or in a joint account.
- A financial institution may reject a direct deposit.
- We can’t deposit more than three electronic refunds into a single financial account.
