How is refund check is payable to Sibling filing tax return for deceased?

When a sibling files a tax return for a deceased person, the refund check is typically payable to the estate of the deceased individual. The sibling, as the executor or administrator of the estate, can deposit the refund into the estate's bank account. If there is no formal estate, the check may be issued in the name of the deceased and require additional steps for cashing or depositing, often involving legal documentation like a death certificate and proof of relationship. Always consult a tax professional for specific guidance in these situations.
