The U.S. Department of the Treasury and the Internal Revenue Service (IRS) have released Notice 2026-36, announcing their intent to issue proposed regulations regarding taxes on excessive compensation and excess parachute payments made by tax-exempt organizations. Under the One Big Beautiful Bill Act (OBBB), the rules governing executive compensation at applicable tax-exempt organizations (ATEOs) have been significantly expanded. Previously, the excise tax applied only to an organization's five highest-compensated employees. Under the new law, the tax may now apply to any employee receiving more than $1 million in annual compensation or receiving an excess parachute payment. The IRS clarified that individuals who were previously classified as covered employees under earlier regulations will remain subject to the rules. In addition, employees meeting the new compensation thresholds after December 31, 2025, may also be included unless specific exceptions apply. The guidance also provides temporary relief for certain volunteers and employees covered by limited-hours and nonexempt-funds exceptions until final regulations are issued. The Treasury Department and IRS expect to publish proposed regulations in the future to provide additional details and implementation guidance for affected tax-exempt organizations.
