Use Form 1310 to claim a refund on behalf of a deceased taxpayer.
Refunds: Representatives do not need to have a POA relationship to claim a deceased taxpayer's refund check, but they do need to file the IRS Statement of Person Claiming a Refund Due a Deceased Taxpayer (Form 1310) with us.
To have a refund issued to anyone other than a surviving spouse or court-appointed or certified personal representative, file IRS Statement of Person Claiming Refund Due a Deceased Taxpayer (Form 1310) when filing the federal return.
Processing times can vary, but it typically takes several weeks for the IRS to process Form 1310 and issue a refund.
