Data was collected from the research sample using the questionnaire form, and the number of distributed questionnaires was (55), distributed to each of the officials and workers in the Iraqi General tax authority, Professionals, and Academics at the University of Baghdad. A set of statistical methods were used to study the relationship between the two research variables, using the statistical program (SPSS) to analyze the data and calculate (the arithmetic mean, correlation coefficient, coefficient of variation, F test, R2 coefficient of determination, T test, Cronbach's alpha coefficient). The research has a significant positive relationship and influence between the framework (COBIT5) and the tax performance. The most influential dimensions of COBIT5 in tax performance dimension delivery, service and support (DSS), followed by evaluation, guidance and control (EDM), while the least influential dimensions in tax performance dimension compliance are planning and organization (APO). The research recommended adopting the COBIT5 internal control framework as a guide for auditors to advise senior management on the efficiency of the internal control system in the tax institution. This includes a governance framework for information technology, which is one of the most important pillars of the corporate governance system. This research also contributes by providing theoretical and practical implications for tax administration to improve the reality of tax performance.
