Abstract
Maximizing government revenues through the policy of financial discipline in Iraq for the period 2004-2019 is one of the main problems of the study represented by Iraq’s dependence on its public revenues from one source, namely oil revenues, at a rate of more than 90% of total revenues, as the Iraqi economy is a unilateral rentier economy that constitutes Oil revenues are a large part of public revenues in it, and then they enter into filling the deficit in the general budget. Therefore, the policy of financial discipline means that the government is able to maintain its financial policies in a clear and consistent manner according to certain rules to achieve financial discipline capable of maximizing the revenues of the Iraqi government and diversifying its sources.
