The main goal of our article is to aply Benford's Law for analysing Finance Operation datasets from Opendata portal of Ministry of Finance of Czech Republic. A chi-square goodness of fit testfor testing null hypothesis is realised and verificated, that data follow the Benford distribution. Further the finance operation is compared in each of the years 2010-2014 from the perspective of Benford's law. There will be also compared different approaches to the analysis of the tested data and compared the results of different testing methods, for example Pearson's chi-squared test of goodness of fit and Z statistics. Benfords Law by the current theory is considered to be a powerfu
