Non-profit organizations such as trade unions, political parties, civic associations, religious organizations, sports associations, social organizations, etc., are defined as organizations established with the aim of providing services to the community without making profits or gains. Financing sources are mainly represented by members’ payments, donations and subsidies and are used to perform NO’s regular activities. Besides its primary activities, an NO can perform other economic activities that then become subject to taxation in accordance with the current legislation. During its life cycle, non-profit organizations are required to comply with statutory regulations which define their regular activities. In order to simplify bookkeeping and accounting duties, or to complement vagueness of the law, non-profit organizations can make their own accounting policies. The former are not statutory but are made in accordance with the internal needs of non-profit organizations and represent the specific principles, bases, conventions, rules and practices applied by the entrepreneur while preparing and presenting financial statements. Once adopted, accounting policies should be applied consistently in order to guarantee fair presentation of NO’s liabilities, assets and capital. The departure from the adopted accounting policies is possible when new accounting policies provide better and more realistic picture of the situation within the non-profit organization, or when there has been significant legislative change which the original accounting policies cannot carry out anymore. Despite the large significance of accounting policies and its impact on the work of non-profit organizations, conducted studies have indicated that no special attention on NOs’ accounting policies within Istrian County was given. The main reason for such behaviour is the low level of awareness on the contribution of accounting policies to everyday business events and the fact that there is no legal obligation for their adoption and implementation.
