Alternative Carbon Resources v. United States, 939 F.3d 1320

Background

Alternative Carbon Resources, LLC claimed $19,773,393 in §6426 alternative fuel mixture tax credits for 2011 based on selling mixtures of biomass-derived feedstock and a small amount of diesel to anaerobic digester operators.
Business model: ACR bought thin-stillage and other organic feedstocks, paid a trucking company to add diesel, and delivered the mixture to digester operators; ACR paid operators disposal/handling fees and collected nominal annual fees from some operators.
ACR’s founders designed the enterprise to capture the tax credits and consulted tax counsel Greg Sanderson; Sanderson repeatedly hedged his advice and sought facts about the economics; an IRS Chief Counsel advisory said digester use is not "used as a fuel."
The IRS audited, disallowed the credits, assessed taxes and excessive-claim penalties under 26 U.S.C. §6675; ACR paid partially and sued for refund in the Court of Federal Claims; the Claims Court granted summary judgment for the United States.
The Claims Court found (1) the purported annual fee lacked economic substance and therefore did not show a bona fide sale, (2) ACR could not prove its specific feedstock produced methane actually used to generate energy, and (3) ACR lacked reasonable cause to avoid penalties because counsel’s advice was hedged and ACR ignored his recommendations.
On appeal the Federal Circuit affirmed, agreeing ACR did not establish a sale for §6426 purposes and could not show reasonable cause to avoid penalties.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether ACR "sold" an alternative fuel mixture under §6426	ACR transferred the feedstock/diesel mixture and collected an annual fee and relief from disposal obligation, so the transfers were sales	The transactions were payments for disposal services, not bona fide sales; fees were nominal and tax-driven	No sale: fees lacked economic substance; transaction treated as buying disposal, not selling fuel
Whether the mixture was sold "for use as fuel"	ACR: digester operators used the mixture in anaerobic digesters that produce methane used for energy	Government: ACR provided no proof its specific mixture produced methane that was used to generate energy	ACR failed to show its mixture produced energy-useable methane; insufficient evidence to establish §6426 "for use as fuel" element
Whether the annual fee/consideration had economic substance	ACR: the fee and disposal-relief constituted consideration supporting a sale	Gov't: fee was nominal, contrived to qualify for credits, and lacked non-tax business purpose; economic substance doctrine applies	Fee disregarded under economic-substance analysis (§7701(o)); transaction lacked meaningful non-tax economic effect
Whether ACR had reasonable cause to avoid §6675 penalties	ACR: reasonably relied on counsel, IRS contacts, private letter rulings, and IRS registration	Gov't: counsel’s advice was hedged, based on incomplete facts; no reliable written IRS guidance; PLRs not precedent	No reasonable cause: reliance on hedged advice and uncorroborated IRS comments was not objectively reasonable; penalties sustained
