The Iranian Institute of Certified Accountants is non-governmental association of accountants in Iran. It was established in 1972 by a group of Iranian founding members who were members of the UK accounting institutes, with the object of promoting the accounting profession in Iran and it has continued its activities uninterrupted ever since.
At the time of IICA's inception, the audit profession consisted of one Government Agency plus a number of indigenous Iranian firms as well as branches of international firms. There was also an Order of Official Accountants at the time which had been established under the Direct Taxation Act of 1967, and whose members carried out tax audits, Qualified accountants, both Iranian and expatriates numbered about 500, of whom some 100 were members of the Order of Official Accountants and IICA at the same time. IICA's membership included others as well. The Order of Official Accountants was abolished in 1980, and IICA remained to be the only professional gathering of accountants in Iran. After the end of the Iraq war and the start of reconstruction in Iran, the institute expanded its activities and a number of research committees on taxation, commercial law and accounting were formed.
