The dissertation thesis describes the methods of calculation of the VAT gap. VAT gap is the difference between the theoretical VAT liability in the whole economy and the accrued VAT receipts. It is expressed in relative terms to the theoretical VAT liability and it approximates the amount of the VAT evasion. The VAT gap in the Czech Republic in the years 2002 to 2010 ranges in average from 16 to 17 %. It is steadily increasing from 11 % to 26 % during the last 5 years of the relevant period. Furthermore, the thesis also analyses the determinants of the VAT gap in the EU member states in the years 2000 to 2006. The share of VAT on total tax revenues and the Tax quota were identified as main tax factors that reduce the VAT gap. On the other hand, the complexity of the VAT system, expressed by the number of VAT rates, the difference between them and the number of preliminary questions to the European Court of Justice, increases the VAT gap. Further significant factor influencing the VAT gap in the negative direction is the Corruption perception Index.

Evaluation of factors affecting the amount of the collection of value added tax. Diploma thesis. Brno: Mendel University in Brno, 2016. The diploma thesis deals with value added tax and the relevant factors that affect the amount of VAT collection in the Czech Republic. In the diploma thesis is then made a comparison of the success of collection of value added tax in the Czech Republic and the European Union. Based on established indicators of tax quota, collection of VAT in relation to total tax revenues and Vat Revenue Ratio, are then calculated actual values to determine the effectiveness of the development in the Czech Republic. The diploma work also compares the performance of the system taxation of the VAT from the viewpoint of methodology VAT Gap. Subsequently drafted actual changes to the VAT system aimed at action against tax evasion. This chapter is then suggested recommendations in the context of structural changes to the VAT system to action against tax evasion. Analysis of the measures taken to action against tax evasion for the year 2016 in the Czech context of the Act no. 235/2004 Coll. The Law on Value Added Tax, are measures calculated and subsequently the development of collections VAT for the year 2016. Part of the calculation is a comparison with the results of the Ministry of Finance of the Czech Republic.

The title of this essay is "What are the effects of a cashless society on VAT evasion –A study on Denmark, Finland & Sweden". Due to an increasingly digitalized world there will be different effects on the economy. We are getting closer to a cashless society every day, but we do not know the consequences that this will have. VAT evasion has long been a problem and has been easy to go through with, due to all the payments made with cash. It would be interesting to see if there is going to be a change in VAT evasion now as we go towards a cashless society. The aim of the study was therefore to answer the question: what are the effects of a cashless society on VAT evasion. To answer this question we focused on collecting data from three Scandinavian countries: Denmark, Finland and Sweden. Many articles were read on the subject before interesting data was collected to be analyzed. The data, mostly gathered from the European Central Bank, included the VATgap, number of payment terminals, number of ATMs, percentage of total payments made with cards, GDP and the Consumer Price Index for each of the three chosen countries. In the theoretical framework the theory around VAT is presented as well as a short discussion about the underlying factors on VAT evasion. There is also a section on how we have chosen to represent the cashless society and how this will be measured in the paper. In order with previous research the hypothesis of the study was formed to be that the VAT gap will decrease as we gotowards a cashless society. Multiple regressions were made on the data collected and the result analyzed. There was no significant relationship found between the VAT gap and any of the three explanatory variables. Instead the VAT gap seemed to be connected to what country that was studied. The coefficients of the variables seemed to indicate that there might be a positive relationship between the VAT gap divided by GDP and the number of payment terminals. The reason for this relationship was discussed to possibly be blamed on the fact that card usage increases the total transactions due to the speed and simplicity of card payments. In order to make the results more reliable it was suggested that the study would be enlarged to include more countries and specifically countries that are less digitalized and perceived to be more corrupt.

The diploma thesis deals with the finding and evaluation of the usefulness and influence of tax authority tools in the Czech Republic and in selected countries of the European Union according to similar indicators. The aim of the thesis is to analyze the effectiveness and utility of the tools used. The number of information in the international exchange of information is compared and the number of tax subjects in the gray economy and their involvement in tax evasion is evaluated. The theoretical part defines core elements of the diploma thesis which are the value added tax, the VAT GAP and the division of tax authority instruments. Concurrently, it describes related mechanisms which shall ensure the elimination of tax evasion. The practical part analyzes selected instruments and their values that the tax authority has at its disposal to combat tax evasion. From the output data, the VAT GAP is estimated using a calculation using the gross domestic product adjustment method. All results found within the Czech Republic will be compared with available comparable data in the EU countries. To conclude, the results are valorized, and instruments are evaluated internationally. It is estimated the amount of the VAT GAP and the possible prediction of future developments.
