The article deals with the VAT gap, its split by causes and determinants, the problem of dependencies. The article also reveals the main ways of calculating the VAT gap - their advantages and disadvantages, summarizes the research done by theoreticians and evaluates the research results. After the theoretical analysis and presentation of the research methodology, the aim is to find out the variables that influence the VAT gap in Lithuania. Using the regression analysis model, the factors determining the VAT gap and their significance, as well as their impact on the decrease / increase of the VAT gap in Lithuania, were identified.

The aim of the paper is to point out the tax system and activity of tax authorities at carrying out a control activity and as well as the activity of its bodies in order to eliminate tax evasions and tax frauds for a sustainable development of state economy. We pay attention to tax systems and deal with tax frauds. We assume that there is no correlation between the number of registered taxpayers and the total tax collection. We also assume that the majority of findings from the tax controls that were carried out will be on VAT whereas there is no correlation between the findings of VAT controls and the number of tax controls carried out. We refer to the importance to strengthen the battle against tax frauds and tax evasions in Slovakia and the aim is to point out the current tax collection and the overall tax administration in the Slovak Republic with the focus on value added tax (VAT). The final part consists of the proposals for the possibilities to combat against tax frauds and tax evasions more effectively.
