IRS headquarters in Washington, D.C., where recent leadership announcements were made to prepare for the 2026 tax season.
When Did the IRS Leadership Shakeup Happen?
The announcement came on January 20 or 21, 2026, with IRS CEO Frank Bisignano sending a letter to all staff detailing the executive reorganizations and priority shifts.

Is the IRS Really Shaking Up Leadership Ahead of Tax Season?
Yes—the IRS has confirmed a major leadership reorganization and new priorities as outlined by CEO Frank Bisignano. The moves aim to improve taxpayer service, boost tax collections, safeguard privacy, and modernize operations amid ongoing challenges like a reduced workforce (down 26% from prior levels due to earlier efficiency-driven layoffs) and implementation of significant tax law changes from recent Republican-backed legislation.
Bisignano expressed confidence in the new structure, stating the agency is well-prepared for a successful filing season. However, the National Taxpayer Advocate’s earlier warnings about potential disruptions from staffing cuts add context to the timing of these adjustments.
Who Is Involved in the IRS Leadership Changes?
Key highlights from the reorganization include:
- Promotions and reassignments in executive roles, with 16 top leaders now reporting directly in a streamlined structure
- Gary Shapley, the former IRS whistleblower known for testimony on high-profile investigations (including Hunter Biden-related matters) and brief past stint as commissioner, named deputy chief of the Criminal Investigation division
- Joseph Ziegler, another whistleblower from similar congressional hearings and recent Treasury advisor, elevated to chief of internal consulting
- Overall focus on strengthening areas like criminal investigations, compliance, and internal advisory functions under Bisignano’s leadership (who also oversees the Social Security Administration)
