This bill, known as the Capitol Police Retirement Reform Act of 2026, proposes significant changes to how retirement annuities are calculated for members of the Capitol Police. It amends title 5 of the U.S. Code to allow certain overtime pay to be included as basic pay for annuity computations. This specifically applies to overtime received under the Fair Labor Standards Act (FLSA) by operation of the Congressional Accountability Act of 1995. A key provision caps the amount of includable overtime pay at 50 percent of the annual statutory maximum for customs officers' overtime pay. For this overtime to be treated as basic pay, a Capitol Police member must have completed at least 15 years of service before their separation. If this condition is met, qualifying overtime amounts attributable to service performed on or after the bill's enactment date will be included, also applying to survivor annuities. The United States Capitol Police will be required to provide annual information to the Office of Personnel Management for the effective implementation of these changes.
