Code of Federal Regulations Title 26. Internal Revenue § 26.1.6664–4T Reasonable cause and good faith exception to section 6662 penalties

(a) to (e) [Reserved]

(f) Transactions between persons described in section 482 and net section 482 transfer price adjustments. For purposes of applying the reasonable cause and good faith exception of section 6664(c) to net section 482 adjustments, the rules of § 1.6662–6(d) apply. A taxpayer that does not satisfy the rules of § 1.6662–6(d) for a net section 482 adjustment cannot satisfy the reasonable cause and good faith exception under section 6664(c). The rules of this section apply to underpayments subject to the transactional penalty in § 1.6662–6(b). If the standards of the net section 482 penalty exclusion provisions under § 1.6662–6(d) are met with respect to such underpayments, then the taxpayer will be considered to have acted with reasonable cause and good faith for purposes of this section.
