Rejecting In re Princeton Office Park, L.P., 423 B.R. 795 (Bankr. D.N.J. Feb. 17, 2010) (Kaplan), and citing with approval Tax Ease Funding, L.P. v. Thompson (In re Kizzee-Jordan), 626 F.3d 239 (5th Cir. Nov. 11, 2010) (Jones, Reavley, Haynes), holder of tax sale certificate under New Jersey law has a “tax claim” for § 511 purposes and is entitled to interest at state statutory rate. “[I]n enacting § 511, Congress chose to use the broad term ‘creditor’, rather than the narrower term ‘governmental units’ . . . . That choice of language lends textual support to the conclusion that the term ‘tax claim’ in § 511 was intended to be broader than a debt owed to a taxing authority for unpaid taxes, and thus can encompass a third-party holder of a tax sale certificate.”
