The College of Business and Accountancy (CBA) is a product of the merging of various academic departments of the then Bataan Community Colleges (now Balanga Campus). Way back in 1974, the Bataan Community College (BCC) started to offer business related courses such as Bachelor of Science in Business Administration (BSBA) major in the fields of management and accountancy, and Junior Secretarial Course.

In School Year (SY) 1981-1982, the Department was headed by Dr. Felisa Legaspi who concurrently served as College Administrator from 1979-1986. The leadership of the BSBA Department was given to Mr. Roberto Vallester from 1983-1984. From 1985-1986, the department was under the care of Mrs. Agripina Banzon, who also performed the function of Assistant Administrator during that time. From 1987-1996, Mrs. Marylou C. Miranda became the head of the department. When Mrs. Miranda passed away in 1996, Mrs. Olivia Perdio took over the headship of the department from 1997-1998.

Meanwhile, the secretarial department was headed by Mr. Basilio M. Zuleta for more than a decade, that is, from 1980-1995. Mrs. Julie Salas was entrusted to lead the secretarial department from 1997-1999.

With the introduction of computers to business and industry, the need to supply the market with manpower who are well-equipped with the latest trend in the area of computers, the Associate in Computer Science(ACS) was offered in 1990 with Mrs. Lorna O. dela Paz serving as department head.

In 1992, the BSBA major in Accountancy was phased out and a new course Bachelor of Science in Accountancy (BSA) was offered.

When the Bataan Colleges was integrated to BPSC, these departments were merged into a single academic unit which was known as the Institute of Business Administration (IBA) in 1999. Mrs. Olivia Perdio became the first head of Institute from 1999-July 2006.

In year 1999, the course ACS was revised and renamed to Associate in Computer Technology (ACT) pursuant to CHED Memorandum Order No. 5 series of 1998. In 2003, additional course, the Bachelor of Science in Management Information Systems (BSMIS) was approved by the BOT. 

In 2005, pursuant to BOT Resolution No. 8, and amended by BOT Resolution No. 27 series of 2006, the Institute was renamed to Institute of Business and Accountancy. In August of the same year, Mr. Sisenando Claudio Masangcap Jr. was designated as the new Dean of IBA.

In 2007, the Institute was renamed to College of Business and Accountancy (BSA) pursuant to the new set-up brought about by universityhood. In same year, the BSBA curriculum was revised in accordance to the provision of CHED Memorandum No. 39 series of 2006. Management as major field of concentration was divided into several specific fields such as marketing management, operations management and human resource development (HRD) management.  In 2019, Bachelor of Science in Hotel and Restaurant Management and Bachelor of Science in Tourism Management became part of the college, in 2021, Bachelor in Public Administration was included as the newest addition.
