The signatures needed on an IRS refund check differ by the check’s payee and your bank policies. You generally can’t sign your spouse’s name. If a check is composed solely to your partner, she should sign the check. If the check is written to both of you, bank policies might differ on signature requirements.
Many banks need that both celebrations sign a check that’s composed to 2 people. While some regional banks are more tolerant with personal checks or checks of small value, they’re most likely to have even more diligence with an IRS refund check. Some banks even require that both parties reveal recognition at the branch when signing a check, particularly if you want money back.
