An Empirical Study on the Determinants of Tax Avoidance Behavior Among Listed Companies on the Vietnamese Stock Market

This study aims to analyze and quantify the impact of firm-specific characteristics on the tax avoidance behavior of listed companies in Vietnam during the period 2019–2023. The dataset includes 400 non-financial firms, collected from audited financial statements. The research employs the Feasible Generalized Least Squares (FGLS) regression model to address heteroskedasticity and autocorrelation issues in panel data. Independent variables include firm size, financial leverage, profitability, firm age, and capital intensity. The findings show that firm size, leverage, and capital intensity are negatively and significantly associated with the effective tax rate, indicating that firms with these characteristics are more likely to engage in tax avoidance. The study proposes several recommendations to improve tax administration and promote better tax compliance among businesses.
