Determinants of tax morale in Spain and Turkey: an empirical analysis

Tax morale is defined as the intrinsic motivation to pay taxes, and is closely related to tax compliance. Determinants of tax morale need to be investigated for a more comprehensive understanding of tax compliance. In this paper, determinants of tax morale in Turkey and Spain are analysed on the basis of World Values Survey data. Firstly, descriptive statistics of the variables used in the models are provided. Since tax morale is an ordered categorical dependent variable, ordered probit models are estimated separately for Turkey and Spain to derive the relations between tax morale and relevant variables. Marginal effects are computed since the coefficients of the models cannot be interpreted because of the nonlinearity of the estimated models. The marginal effects related to the top level of tax morale category are presented. The independent variables are combined by demographic factors, employment categories, economic status of the respondents and social capital variables. The findings from the estimated model suggest that social capital variables and some of the demographic factors have important effects on tax morale in Turkey. Confidence variables have positive effects; if taxpayers feel confidence in political entities they are willing to pay taxes. Religion and national pride affect tax morale positively. On the other hand, the results are different for Spain; social capital variables do not have effects on tax morale. Specifically, confidence variables are found to be statistically insignificant. Age, education level and the income level have significant effects on tax morale in Spain.
