Herbert Carl Heintz appeals from the Tax Court’s summary judgment permitting the Internal Revenue Service (“IRS”) to collect unpaid trust fund recovery penalties under 26 U.S.C. § 6672 on taxes withheld from employees’ paychecks. We have jurisdiction under 26 U.S.C. § 7482(a)(1). We review de *2 novo, Sollberger v. Comm’r , 691 F.3d 1119, 1123 (9th Cir. 2012), and we affirm.

The Tax Court properly sustained the collection action because Heintz failed to raise any permissible issues or defenses at the collection due process (“CDP”) hearing, and the Tax Court properly concluded that Heintz could not challenge the existence or amount of the underlying tax liability at the CDP hearing because Heintz had a prior opportunity to dispute that liability and did not exercise it. See 26 U.S.C. § 6330(c)(2) (listing issues that may be considered at the CDP hearing); § 6330(c)(2)(B) (taxpayer may raise at the CDP hearing challenges to the existence or amount of the underlying tax liability only if he or she did not receive a notice of deficiency or otherwise have an opportunity to dispute such tax liability); § 6330(d) (the Tax Court’s jurisdiction is limited to the issues properly raised at the CDP hearing); see also Boynton v. United States , 566 F.2d 50, 53 (9th Cir. 1977) (imposition of penalties under § 6672 does not require a notice of deficiency).

We reject as without merit Heintz’s contentions that the IRS lacked a reasonable basis to deny him an extension of time to appeal the underlying liability, and that precluding Heintz from challenging his liability for the trust fund recovery penalties at the CDP hearing violated his due process rights.

AFFIRMED.
