Fiscal management represents, on the one hand, a component of public finances, and on the other - a system of management of fiscal flows by applying forms, market methods and decisions with scientific basis in the field of income management and tax expenditures at different levels. It consists of two components: fiscal process and fiscal mechanism. Taxes and fiscal system form the core of fiscal management, whose international practice has developed a wide diversity. Fiscal process constitutes the totality of fiscal bodies’ activities empowered to prepare, examine and examine fiscal budgets. It also includes tax system, fiscal policy and tax law. That is to say, fiscal management is a complex of relations constituted in the fiscal legal basis, based on the fiscal system within accepted conception of fiscal policy. The fiscal mechanism combines all methods and rules of formation and maintenance of fiscal relations that ensure the accomplishment of fiscal policy’s aims. For this purpose, it is necessary to set up an integrated system of fiscal planning, fiscal regulation and fiscal control. The main task of fiscal management is to harmonize the functioning of basic elements in order to satisfy based on mutual advantage of fiscal bodies and of the taxpayer’s interests. The fiscal system plays an important role in ensuring financial stability, which has been reflected in different theoretical conceptions. In Republic of Moldova fiscal management is in the process of being set up, main problem being its basic elements combining. In addition, it presents as problematic the achievement of the basic purpose - the interest’s harmonization of taxpayers and State. A complex of problems are related to structure of collected taxes, fiscal monitoring and control of taxpayers, ensuring the consistency and predictability of fiscal policy. There are also fundamental problems caused by the existence of shadow economy, tax evasion and corruption in public bodies. All these impede the processes of European integration and require further improvement of fiscal management in Republic of Moldova.
