IRS CEO Testifies on Investigations into Nonprofits

On April 15, 2026, Internal Revenue Service (IRS) Chief Executive Officer (CEO) Frank Bisignano testified before the Senate Finance Committee, where he faced questions by policymakers about significant staff reductions at the agency, implementation of the major tax bill enacted in 2025 and possible investigations into nonprofits. When questioned by Senator Raphael Warnock (D-GA), Bisignano testified that neither the president, vice president nor any White House staff have asked the IRS to investigate any specific taxpayers or nonprofits.

He also indicated that if such a request were made, the IRS would report that activity to the committee. Bisignano confirmed that nonviolent protests and litigation against the Trump administration are not grounds for IRS investigations. Bisignano previously testified before the House Ways and Means Committee, where he was asked about President Donald Trump’s directive to the IRS to investigate nonprofits accused by the administration of domestic terrorism. Bisignano promised lawmakers at the time that the IRS would not initiate audits, investigations or revocations of tax-exempt status based on political targeting.

Given recent developments, Bisignano’s testimony is particularly relevant. The IRS and the Federal Bureau of Investigations (FBI) has formed a new initiative to investigate nonprofits over suspected possible links to domestic terrorism.
