Today, the transactions related to economic resources (money, foreign exchange, mine, stock market volume) and the fact that these transactions are carried out directly or indirectly by the bank and that this carries a high risk in parallel with this has brought internal audit to an important dimension. In recent years, with the growth in our country, institutionalism and the control mechanism in this field have come to the forefront, and it is desired to make the invisible in economic development visible, analyze them and at the same time control and turn them into a reportable system.
The main purpose of the research is to investigate the effect of internal audit on effective corporate governance. Internal audit is seen as an integral part of all institutions and organizations in the context of corporate governance.
