The activities of non-profit organizations are focused on the public interest. In the most cases, non-profit organizations are organized through the legal form of the association and in the function of providing non-profit services. The financial operations and accounting of non-profit organizations are regulated by the Law on Financial Operations and Accounting of Non-Profit Organizations, which belong to the associated regulations. Due to the increase in the number of non-profit organizations and thus increase in the spending of public money, it leads to greater controls and supervision of business. In this context, the law also states the obligation to submit financial reports of non-profit organizations to the competent body for their publication through the Register of non-profit organizations maintained by the Ministry of Finance.
