The lack of fiscal discipline is one of the most pressing issues in the framework of various economic systems today. The consequences of the global economic crisis have shown all the weaknesses of measures and mechanisms in terms of decision-making in fiscal policy. This problem can be seen now in almost every country. The problem of inadequate implementation of fiscal policy and the maintenance of fiscal discipline is reflected in the fact that their consequences are not visible right away, but tend to show their negative effects much later. Today, we have a situation where a certain current government suffers badly implemented prior fiscal discipline of a previous government. The paper identified causes of fiscal indiscipline, which is most easily seen in the budget process. In addition to determining the causes of fiscal indiscipline, the author puts forward a set of different possible solutions that could positively affect the stabilization of the growing public debt and eliminate the cause of fiscal indiscipline. Possible solutions are analyzed, as well as the positive and negative aspects of their use, and possible implementation problems of specific solutions.
