In March 2025, secretary of the treasury Scott Bessent promoted Shapley and his associate, Joseph Ziegler, to senior advisors to investigate the IRS. That month, he was named as deputy chief of the IRS Criminal Investigation. The following month, Trump named Shapley as the acting commissioner of internal revenue to succeed Melanie Krause over a dispute involving information on taxpayers sought by Immigration and Customs Enforcement.

IRS Criminal Investigation agent (2009–2025)
Shapley began working in the Internal Revenue Service's Criminal Investigation division in July 2009. He supervised the agency's investigation into Hunter Biden, the son of president Joe Biden. Shapley publicly alleged that the Department of Justice had "slow-walked" the investigation into the younger Biden in an interview with CBS News in May 2023. Michael Batdorf, the director of field operations at the Internal Revenue Service, claimed that he decided to remove Shapley and his team from the Biden case in December 2022. Batdorf cited an apparent statement from David C. Weiss, who oversaw the Biden investigation at the Department of Justice, claiming that Shapley could not "remain objective in the investigation"; notes from Shapley released by Politico in September revealed that he had concerns over Weiss beginning in October 2022.That month, Biden sued the Internal Revenue Service over alleged violations of privacy, referencing Shapley and his associate, Joseph Ziegler; Biden dropped his lawsuit in April 2025. Shapley testified before the House Committee on Ways and Means about the investigation into Biden. His statements were made public in June 2023. Shapley's testimony was used by some congressional Republicans to counter Weiss's claim that he had independence in the special counsel investigation. Shapley testified before the House Committee on Oversight the following month alongside Ziegler, alleging that political bias caused Weiss's investigation to be slow-walked and delayed. He and Ziegler spoke with the Committee on Ways and Means in December, after the impeachment inquiry into Joe Biden began.
After Biden plead guilty to tax-related charges in September 2024, Shapley and Ziegler sued one of Biden's lawyers, Abbe Lowell, accusing him of defamation; a federal judge granted Lowell's motion to dismiss the lawsuit in October 2025, referring to specific comments that Lowell had made as "reasoned—albeit aggressive—positions". Shapley and Ziegler repeatedly alleged that the IRS removed them from the case for pursuing leads related to Joe Biden. In December, the Office of Special Counsel substantiated their claims.
