The changes in the tax system of the Republic of Croatia in the period from 2020 to 2022 are extensive and are therefore considered reforms. Each year of the mentioned period was analyzed through changes in the main tax laws: General Tax Law, Income Tax Law, Profit Tax Law, Value Added Tax Law and other laws. With the adopted changes, the tax laws try to be harmonized with the acts of the European Union. Also, efforts are being made to achieve positive effects on the economy of the Republic of Croatia and to reduce the tax burden on its citizens, craftsmen and entrepreneurs. The aforementioned changes are taking place at the time of the global pandemic of COVID-19, which, due to its specificities, significantly affects budget revenues (through EU subsidies) and expenditures (through co-financing of measures to maintain economic activity and preserve jobs and the costs of the health system). In conditions of reduced economic activity and budget deficit, tax reforms remained in the shadow of the specific circumstances in which they were implemented. Nevertheless, the numerous positive effects that have been achieved are presented chronologically through the phases of their implementation. The most important positive effects of tax reforms in the mentioned period are the increase of the minimum gross and net salary, the avoidance of double taxation in trade between business entities within the European Union in cases where goods are stored for a short period of time, the increase of the threshold for corporate tax payers and the general modernization and humanization of tax regulations, which is particularly reflected in the changes to the Enforcement Act, which introduced a whole series of changes regarding payments by the employer in favor of the bailee to a protected account.
