Abstract

Purpose: This study examines the impact of tax extensification and intensification on individual income tax receipts, determining whether expanding the taxpayer base and improving compliance significantly contribute to revenue growth. Research Design and Methodology: A quantitative approach using multiple linear regression analysis was applied to assess the relationship between tax extensification, tax intensification, and individual income tax receipts. Primary data were collected from 100 registered taxpayers at KPP Pratama Jayapura through a structured questionnaire-based survey. Statistical tests include validity, reliability, normality, heteroscedasticity, multicollinearity, and hypothesis testing, including the coefficient of determination, t-test, and F-test. Findings and Discussion: The results indicate that tax extensification and intensification significantly enhance tax revenue. Expanding the taxpayer base and improving compliance monitoring contribute to increased revenue collection, aligning with attribution theory and highlighting internal (awareness, responsibility) and external (regulatory frameworks, enforcement) compliance factors. Implications: This study highlights the need for more substantial tax administration, digital infrastructure, and taxpayer education. Governments should enhance compliance monitoring and enforcement to sustain revenue growth. Future research should explore additional compliance factors, such as penalties and digital tax services.

Abstract

Purpose: This study explores the impact of auditor retention and firm size on audit quality, emphasizing their relevance to audit independence and corporate governance. Understanding these factors is crucial for regulators and businesses aiming to enhance financial reporting quality. Research Design and Methodology: The study focuses on 15 manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2017 to 2019. Using secondary data from IDX records, logistic regression analysis was conducted to examine the relationships between auditor retention, firm size, and audit quality. Findings and Discussion: The findings show that auditor retention has a negative and insignificant effect on audit quality, indicating that frequent auditor changes do not necessarily improve audit outcomes. Similarly, firm size negatively and insignificantly affects audit quality, suggesting that larger companies do not always receive superior audits. These results challenge the belief that auditor rotation and firm size are primary indicators of audit quality. Implications: The study suggests that companies should prioritize auditor competence over rotation policies, while regulators may need to reassess mandatory auditor rotation’s effectiveness. Future research should consider other factors, such as auditor tenure, audit fees, and corporate governance, to gain a more comprehensive understanding of audit quality determinants. These insights can guide policymakers in enhancing audit standards and financial reporting integrity.
