Unpublished opinions are not binding precedent in this circuit.

Douglas Stauffer Bell and Nancy Clark Bell seek to appeal the tax court’s order dismissing in part, and remanding in part to the Internal Revenue Service Office of Appeals, their petition in the underlying collection due process proceeding. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2012), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2012); Fed. R. Civ. P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 545-46, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order the Bells seek to appeal is neither a final order nor an appealable interlocutory or collateral order. Accordingly, we grant the Commissioner’s motion to dismiss the appeal for lack of jurisdiction. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

DISMISSED
