Data collection techniques were carried out by interviewing, observing, studying literature /documentation and sources triangulation. The results of the study concluded that the effectiveness of the Tax Audit in the Large Taxpayer Tax Office Four in 2019 has not reached optimal results because of the targets set have not yet been achieved.
