Tax practitioners need to be prepared for a shifting landscape in the IRS’s collection efforts in 2026 and beyond. The last several months have made clear that, despite the IRS facing personnel cuts and work stoppages due to the government shutdown, the agency’s collection efforts continue to remain a top priority. The landscape of tax collection is undergoing significant changes as the IRS is placing a heavy emphasis on enhancing collection capabilities using advanced notices, analytics and artificial intelligence; and less of one on audits, which are anticipated to decline. A pivotal development in this evolving scenario is the US Supreme Court’s ruling in Zuch v. Commissioner in June and its impact on liability disputes brought forward during the collection process. This decision could have far-reaching implications for taxpayers and tax practitioners alike, necessitating a reevaluation of strategies in dealing with IRS collection efforts.
