On April 24, 2020, the US Court of Appeals for the Eighth Circuit published its opinion in Wells Fargo & Co. v. United States, No. 17-3578, affirming a district court’s holdings that the taxpayer was not entitled to certain foreign tax credits and was liable for the negligence penalty for claiming the credits. Much has been written about the substantive issue, which we will not discuss here. Instead, we focus on the Eighth Circuit’s divided analysis relating to the reasonable basis defense to the negligence penalty.
In Wells Fargo, the taxpayer relied solely on the reasonable basis defense to the government’s assertion of penalties. Under Internal Revenue Code (IRC) section 6662(b)(1), a taxpayer is liable for penalty of 20% of an underpayment of its taxes attributable to its “negligence.” Various defenses are potentially applicable to the negligence penalty, which we recently discussed in detail here. One such defense is if the taxpayer can show it had a “reasonable basis” for its position. Under Treas. Reg. § 1.6662-3(b), this defense applies if the taxpayer’s return position was “reasonably based on” certain authorities specified in the regulations.
