Slovenian income taxes and analysis of their tax expenditure in 2006-2010

Tax expenditure analyses have been an important element in the supervision of reform processes linked to implementing different kinds of tax incentive and the management of a correct tax policy. The paper provides an evaluation of tax expenditure in Slovenia relating to personal income tax and corporate income tax. Four consecutive tax years were selected for the calculation of the tax expenditure on personal income tax (2006-09), while three consecutive years were selected for the corporate income tax calculation (2008-10). The tax expenditure calculated for personal income tax was highest in 2006 and reached 5.2% of GDP. After several changes in personal income tax, expenditures decreased to around 3% of GDP in the following three years. The tax expenditure calculated for corporate income tax was much lower as compared to GDP than for personal income tax, reaching around 0.2% of GDP.
