Lab experiment to investigate tax compliance: the case of future taxpayers' behavior in Russia and Belarus

The paper aims to examine the internal motivation of taxpayer's behavior, and the factors affecting tax morale and voluntary tax compliance The authors provide scientific results of the tax experiments in post-Soviet countries (Russia and Belarus). The laboratory tax experiment was carried out in a form of a business game engaging students of various levels of education and background. The controllabi-lity of the experiment with the impossibility of material encouragement is ensured in the student's environment in the form of scores to the final attestation. In order to obtain data on tax behavior motivation, a survey on attitude to tax system w.s conducted. Respondents (experiment participants) were asked to indicate their level of agreement with defined statements by Likert scale. To assess the differences between two groups of participants (who paid and who do not paid tax), the data obtained as a result of filling out the questionnaire using the Mann-Whitney U-test and the Kruskal-Wallis H-test were analyzed. The study results affirmed the hypothesis generated earlier, the personal tax morale influences the national tax system and the tax behavior of an individual. The article proves that the awareness of the ways government spends public revenue and the trust level to the state and tax system itself influence tax behavior directly. The civil awareness on the real state of fiscal distribution increases the trust level to the government among taxpayers and is the essential motivation to pay taxes. The developed methodology may be used in an educational process to increase tax literacy, its further application in the scientific research will allow us to derive evidence-based methods and ways to directly influence tax behavior, which may enlarge the public revenue in the times of an unstable global economy.
