US Tax Court preserves equitable tolling for BBA partnership petitions

The reconsideration motion did not change the prior holding

The Commissioner argued that the court’s treatment of the Bipartisan Budget Act partnership deadline conflicted with North Wall Holdings under the former TEFRA regime. The court said it had already reconciled those decisions in Kings Road and Big Apple Tompkins Realty, and that reconsideration was not the forum for repeating rejected arguments or introducing new theories. The motion had been filed on 21 October after the court’s September Kings Road opinion.^[1]

The statutory deadline remains 90 days

The decision does not extend section 6234(a)’s 90-day period for petitioning against a final partnership adjustment. It leaves undisturbed the earlier holding that the deadline is non-jurisdictional and may be equitably tolled. Equitable tolling is exceptional rather than automatic and depends on the partnership diligently pursuing its rights and extraordinary circumstances preventing a timely filing.^[1]

TEFRA and BBA procedures remain distinct

The court rejected the proposition that similar wording required identical treatment under the two regimes. It referred to the more complex and multilayered TEFRA assessment process and concluded that the BBA’s different structure supported its existing result. The opinion therefore concerns the BBA partnership audit route, not every federal tax petition deadline. The court also declined to use reconsideration to address newly advanced administrative-burden theories.^[1]

Partnerships and multinational groups invested through US partnerships should continue to calendar the ordinary 90-day deadline from a final partnership adjustment and maintain reliable notice and partnership-representative controls. A missed deadline should not be treated as cured: potential equitable tolling requires prompt factual and legal review, evidence of diligence and proof of circumstances outside the partnership’s control. Groups should preserve the final adjustment, delivery evidence, powers of attorney, IRS contacts and protective-filing decisions because the later dispute will turn on facts rather than a general extension.^[1]
