U.S. v. Guyton, Slip Copy, 2009 WL 1308431 (M.D.Fla. May 08, 2009)

The IRS is the "über" creditor of any probate estate. Why? Two reasons. First, the personal representative (PR) is personally liable for any of the decedent’s unpaid taxes to the extent the PR pays any debts due by the decedent before paying the decedent’s tax liability. 31 U.S.C. § 3713(b); IRS Manual § 5.5.1. There’s nothing like personal liability to focus the mind. Second, the normal rules simply don’t apply to the IRS. As the court ruled in the linked-to order, the IRS is NOT subject to the limitations periods applicable to all other creditors:

Turning to Defendant’s final threshold argument, case law makes clear that the Government’s claim is not subject to state statutes of limitation, including Florida Statute § 733.705(8), absent its own consent. See e.g., United States v. Summerlin, 310 U.S. 414 (1940); see also United States v. Kellum, 523 F.2d 1284, 1286 (5th Cir.1975).
