This study examines the effects of fiscal policies implemented since the foundation of the Republic of Türkiye on fundamental fiscal indicators. For this purpose, only those within the fiscal policy scope were considered. While examining the implemented fiscal policies and the effects of these policies on fundamental fiscal indicators, the Turkish economy was divided into six periods.

The public budget had an average deficit of 2.45%. The period when economic growth performance was the best, and the size of the public economy was the period of 1923-1929 liberal policies. The period when economic growth performance was the lowest and the budget deficit was the period of the 1980-2001 transition to a market economy.
