Deputy Commissioner

Estelita Caleon-Aguirre is a distinguished tax expert and public servant who served as Deputy Commissioner of the Bureau of Internal Revenue, where she played a key role in tax administration and revenue management.

Entering the Bureau of Internal Revenue (BIR) on April 20, 1965, as a Revenue examination Aide II (a rank and file position), Ms Aguirre rose from the ranks to reach the top management of the BIR when she was appointed by President Fidel V. Ramos as Deputy Commissioner (the second-highest ranking position in the revenue service) for Resource Management on November 30, 1995 and later as the first female Deputy Commissioner for Operation in 1997. President Joseph Estrada re-appointed her as Deputy Commissioner for Resource Management on July 1, 1998 while President Gloria Macapagal Arroyo re-appointed her to the same deputy position on March 22, 2001.

ASEAN Federation of Accountants (AFA)

President

Ms. Aguirre holds the distinction of being the first, and only, female President of the AFA, to date. Her leadership at AFA – serving as Deputy President (2012-2013) and President (2014-2015) – was described by members and officers of the Federation as “transformative”. Having noticed that the assignment of activities was being done through temporary assignments to whoever volunteers, she initiated the creation of Task Forces (patterned after PICPA’s Committees) to handle priority projects during her administration, the most notable of which was the Task Force on “Closing the Gaps Between and Among ASEAN Member Bodies”. The Task Forces served as the workhorses of the Federation, and proved to be so effective that they were institutionalized and are now part of the permanent structure of the AFA. It may also be noted that prior to 2014, AFA staff were borrowed from the Institut Akuntan Publik Indonesia (IAPI) and the home country of the incumbent President, and worked in a borrowed space from IAPI. In a historic move, Ms. Aguirre organized a Strategic Planning Conference held in Cebu City, where she initiated the establishment of the very first AFA Secretariat Office, appointing Indonesian Aucky Pratama as its very first Executive Director.
