IFAC's Constitution and Bylaws detail the responsibilities and authority of IFAC's Council, Board, and Board committees. They also address IFAC’s mission, membership requirements, and the election/appointment of IFAC officers.

The IFAC Constitution was revised in 2011 to address practical issues identified by the Board, Nominating Committee, IFAC staff, and member bodies, evolving trends in governance best practice, and a need to clarify and conform the provisions of the Constitution and Bylaws with other IFAC governance-related documents, such as the Council Terms of Reference, the Board Terms of Reference, and the IFAC Internal Reference Manual. This version of the IFAC Constitution was approved by the IFAC Council in November 2011.
