Antecedents of taxpayers’ intentions to engage in tax evasion: evidence from Barbados

Tax evasion has been a major problem for governments around the world, with innovative and ever-changing schemes making the practice increasingly difficult to regulate. In light of this, this study aims to use the extended version of the theory of planned behaviour (TPB) (Beck and Ajzen, 1991) to predict individuals’ intentions to engage in tax evasion.

The research adopts a two-stage approach for data collection and analysis. First, the authors obtained survey data from 150 taxpayers in Barbados to conduct multivariate analyses to test the validity of the study’s hypotheses. The authors also used several open-ended questions on the survey instrument to conduct thematic analyses to further explore the influence of the antecedents of intentions to engage in tax evasion. Second, the authors conducted a focus group with two tax officials and three tax advisors.

The authors find that attitudes toward the behaviour, perceived behavioural control and moral obligation are significant predictors of intentions to engage in tax evasion. Factors cited as encouraging tax evasion are perceived fairness, tax authorities’ institutional infrastructure and responses, potential financial benefit, perceptions of inequality, low level of trust in tax authorities, perceived poor use of tax revenues and poor treatment of taxpayers. Conversely, factors cited as discouraging tax evasion include fear of prosecution, high morals and potential adequate governmental regulation.

The study measures intentions to engage in tax evasion rather than actual behaviour. The study does not measure social desirability bias.

This paper tests the applicability of variables used in the extended version of the TPB to predict intentions to engage in tax evasion in a Caribbean-based emerging economy. It also applies a mixed-methods approach of collecting data from taxpayers, tax advisors and tax officials.
