ABSTRACT This study aims to analyze the comparison of financial performance of companies in the infrastructure sector listed on the Indonesia Stock Exchange (IDX) before and after the implementation of the tax amnesty policy in Indonesia. The second phase of the tax amnesty policy, implemented in 2022, is expected to improve tax compliance, strengthen the national revenue base, and stimulate economic growth, particularly in the infrastructure sector as a strategic pillar of development. This research adopts a quantitative method with a comparative approach. The data used are secondary data obtained from the companies’ annual financial reports for three years before (2019–2021) and three years after (2022–2024) the implementation of the tax amnesty. Financial performance is measured using financial ratios such as Return on Assets (ROA), Debt to Equity Ratio (DER), Current Ratio (CR), and Total Asset Turnover (TATO). Data analysis was conducted using the Normality Test and the Wilcoxon Signed Rank Test. The results show that there are significant differences in several financial performance indicators before and after the implementation of the tax amnesty policy, indicating the policy's impact on the financial health of infrastructure companies listed on the IDX. These findings provide implications for the government and market participants regarding the effectiveness of fiscal policy on the real sector.
