CONTROLLING THE GLOBAL MINIMUM TAX REVENUE: AN ANALYSIS OF FACTORS AFFECTING AUDIT EFFECTIVENESS AND STRATEGIC ORIENTATION AT THE STATE AUDIT OFFICE

Abstract

Vietnam’s adoption of the Global Minimum Tax (GMT) under Resolution No. 107/2023/ QH15, effective from the 2024 fiscal year, creates an urgent need to effectively control the additional tax revenue, estimated at approximately VND 14,600 billion annually. This study employs a mixed-methods approach, combining quantitative research with qualitative analysis. Through a survey of auditors and tax experts, the paper quantifies the impact of various factors on the effectiveness of auditing GMT revenue. Regression results indicate that Auditor Competence (β=0.382) and Data & IT Infrastructure (β=0.315) are the two most significant factors influencing audit effectiveness. Based on these findings, the author proposes strategic solutions, focusing on revising the application guidance for VASSA 1315 and deploying digital audit tools to enhance audit efficiency for this specific tax mechanism, thereby contributing to the realization of the State Audit Development Strategy (SAV) by 2030.
