The test results showed that the taxation training and taxation experience of the expenditure treasurer directly had a positive and significant effect on the performance of the implementation of its tax obligations, while after being mediated by the competency variable in the taxation field, the influence of training and experience of expenditure treasurer on the performance of the implementation of taxation obligations was no longer significant. That is, in accordance with the concept of mediation by Baron dan Kenny (1986), the taxation competence becomes a perfect mediator of the influence of taxation training and taxation experience of expenditure treasurer on the performance of the implementation of taxation obligations.
