Ripped from the Headlines: High Impact Civil Tax Decisions

Todd Welty will participate in a panel on high impact civil tax decisions. The panel will address questions that practitioners need to be able to answer. Can you show that your client's restructuring transaction has economic substance, in a post-Liberty Global world? Is your distributive share of ordinary partnership income at risk of being treated as self-employment income, or are you covered by the Fifth Circuit's decision in Sirius Solutions? Do taxpayers you advise have a defense against the imposition of failure-to-pay penalties or interest relief, either under Kwong for COVID-era deadlines or because, like the plaintiff in Jarkesy, they weren't afforded the right to a jury trial? These are among the hot-button issues that the panel will address as it analyzes a recent wave of significant, high-profile tax cases. Panelists will cover these and other key holdings and their practical implications, providing insight on how they may influence audit strategy, litigation risk, and future IRS enforcement positions.

Other speakers include moderator Jason B. Grover, Esq., Counsel, Latham & Watkins; and panelists Gilbert S. Rothenberg, Esq., Adjunct Professor, American University; Sanford J. Boxerman, Esq., Shareholder, Neill Schwerin Boxerman; and Rachel Borden, Esq., Counsel, Mayer Brown.
