Prof. R. Soemardjo Tjitrosidojo and four other first graduates of the Faculty of Economics, University of Indonesia, namely Drs. Basuki T. Siddharta, Drs. Hendra Darmawan, Drs. Tan Tong Joe, and Drs. Go Tie Siem, founded the Indonesian Institute of Accountants (IAI) on December 23, 1957.
On April 7, 1977, twenty years after the IAI was founded, Drs. Theodorus M. Tuanakotta established the Public Accountants Section as a forum for public accountants in Indonesia to implement public accountant development programs.
At the 7th IAI Congress in 1994, IAI members agreed to grant autonomy to public accountants by transforming the Public Accounting Section into a Public Accounting Compartment. This was in response to developments in the capital market and banking sector in Indonesia, which required changes to Financial Accounting Standards and Public Accounting Professional Standards to align with international standards.
On May 24, 2007, the Indonesian Institute of Certified Public Accountants (IAPI) was officially established. This establishment was decided at the Extraordinary General Meeting of Members of the IAI – Public Accountants Compartment. This organizational change was intended to meet the requirements of the International Federation of Accountants (IFAC) regarding the profession and ethics of public accountants.
KMK no. 443/KMK.01/2011 was issued regarding the Establishment of IAPI as a Professional Association of Public Accountants which recognizes IAPI as an organization authorized to conduct the Public Accountant Professional Examination, prepare and determine the Professional Standards and Ethics of Public Accountants, and organize Continuing Education Programs, as well as Public Accountant Quality Reviews.
