The results of the study show that the policy government’s influence positively and significantly on motivation to pay tax with a coefficient of 0.246 and p-value = 0.021. Trust in government also has a positive and significant impact on motivation to pay tax with a coefficient of 0.342 and p-value = 0.002. Besides, motivation to pay tax influences significantly compliance with a coefficient of 0.424 and p-value = 0.000. The mediation test shows that motivation partially mediates the influence of government policy and trust on compliance with tax payments with VAF values of 27.8\% and 23.8\% respectively. The study gives additional proof that policy government and trust have an important role in increasing motivation and compliance to pay taxes in the MSME sector.
