Justice, power and voluntary tax compliance: a moderation analysis among taxpayers in Addis Ababa, Ethiopia

Purpose

The aim of this study was to examine the moderating roles of the legitimate power and distributive justice of the tax authority on the effect of procedural justice on the voluntary tax compliance of taxpayers in Addis Ababa, the capital of Ethiopia, by using survey data collected from taxpayers in the city.

Design/methodology/approach

Data for the study were collected from 800 sample taxpayers who were drawn by using a systematic sampling technique. The variables of the study were constructed as indices from composing the scale items developed and tested for their validity by prior researchers. Having collected the data by using a 7-point Likert scale questionnaire and forming the latent variables, hierarchical multiple regressions were applied to determine the moderating effects of the two variables (i.e. legitimate power and distributive justice) on the effect of procedural justice on voluntary tax compliance.

Findings

The author found that both the legitimate power of the tax authority and distributive justice of the authority moderate the effect of procedural justice on voluntary tax compliance. The moderating roles of the two variables appear to be opposite in that low (but not high) distributive justice and high (but not low) legitimate power of the tax authority stimulate the effect of procedural justice on voluntary tax compliance.

Research limitations/implications

The first limitation is that the data used in this study are self-reported data while the subject of the study is sensitive subject about which respondents are not believed to provide genuine responses. This is presumably because taxpayers are less likely to confess their tax evasion as they fear legal actions following their self-report. Hence, other controlled methods such as the experimental design are recommended to replicate the results of this study. The second limitation is that data for the study were gathered through a one-time cross-sectional survey and hence it would not warrant a causal claim between the study variables. Consequently, other research with a longitudinal or experimental design might warrant a causal relationship between the variables.

Practical implications

Therefore, the tax authorities must endeavor to attain high legitimacy by doing “the right things” as perceived by the taxpayers so that their tax-related decisions gain acceptance from the decision recipients. Tax policy makers as well ought to consider the importance of and the relationship between procedural justice, distributive justice and legitimate power of the tax authority in order to attain the maximum possible voluntary compliance of taxpayers that significantly reduces the administrative cost of taxes.

Social implications

The study benefits society by enhancing tax compliance and hence helping the government secure a better amount of tax revenue and provide better public goods and services.

Originality/value

The findings of this study are of high theoretical and policy significance. Theoretically, the findings contribute to the integrative literature on economic deterrence and social-psychological factors that are responsible for voluntary tax compliance decisions. The parallel moderating roles of the two variables on the relationship between procedural justice and voluntary cooperation in a single model and in the tax compliance context are novel. In terms of applicability to policy formulations, they shed light on the need for a shift from a pure focus on aggressive tax audits and penalties, especially in emerging economies to a combination of the tax audits and the nurturing of the voluntary deference of taxpayers to the tax authority's decisions. Caution must, however, be taken that the results of this study may not be applicable to tax environments in other countries.
