Trump Sues I.R.S., Seeks at Least $10 Billion Over Tax Return Leak

President Trump sued the Internal Revenue Service on Thursday, Jan. 29, 2026, in federal court in Florida, demanding at least $10 billion over the unauthorized leak of his tax returns from his first term; the suit also names his two eldest sons and his family business as plaintiffs.

The filing charges that the I.R.S. and the Treasury Department failed to prevent a former I.R.S. contractor, Charles Littlejohn, from gaining access to Mr. Trump’s tax documents, which were shared with The New York Times, the complaint says. Mr. Littlejohn is serving a five-year prison sentence for taking tax documents about Mr.

Trump and other wealthy Americans and giving them to news outlets. The suit seeks billions in damages while noting that federal law closely guards tax information. The complaint notes that Mr. Trump appointed the leaders of the I.R.S. and the Treasury Department, a fact the report says sets up the possibility that Mr.

Trump’s aides could decide how the agencies respond to the lawsuit. The filing follows Mr. Trump’s earlier demand that the Justice Department pay him about $230 million in compensation for federal investigations, a request the report describes as without parallel in American history.
