The current study targets to examine the relations between motivation, attitude, job satisfaction, and tax administration efficiency with leadership as a moderator from the tax employee’s perspective using the Yemeni environment. The questionnaires were distributed among 505 employees of the Yemeni Tax Authority as part of the survey technique, exactly from six governorates. As a result, 306 questionnaires were appropriated for further analysis. Respondent data were analyzed using SPSS.23 and PLS software. The analysis results manifest that motivation, attitude, and job satisfaction significantly influence tax administration efficiency. Whereas motivation presents about 40% of the influence, attitude is about 31% of the influence, and job satisfaction is about 15% of the influence on the efficiency of tax administration. Furthermore, for the influence of leadership as a moderating variable, it was found to moderate the impact of job satisfaction and attitude on tax administration efficiency (β = 0.157; P < .001; β = 0.105; P < .01). On the contrary, the findings also show that leadership cannot moderate the correlation between motivation and tax administration efficiency (β = –0.061; P > .05). The findings of this study are helpful for the tax administration in the context of Yemen.
