Peran Moderasi Manajemen Laba Dalam Thin Capitalization Terhadap Tax Avoidance: Studi Kasus Perusahaan BUMN Yang Terdaftar di Bursa Efek Indonesia Tahun 2021-2024

This study aims to analyze the effect of thin capitalization on tax avoidance and examine the moderating role of earnings management in state owned enterprises listed on the Indonesia Stock Exchange during 2021 to 2024. The research employs a quantitative associative approach using purposive sampling based on the availability of complete financial statements. Thin capitalization is measured using the Debt to Equity Ratio, tax avoidance is measured using the Effective Tax Rate, and earnings management is captured through discretionary accruals using the Modified Jones Model. Data were analyzed using Moderated Regression Analysis (MRA) after passing classical assumption tests to ensure model validity. The results indicate that thin capitalization has no significant effect on tax avoidance, while earnings management has a significant influence on tax avoidance. Moreover, earnings management moderates the relationship between thin capitalization and tax avoidance by strengthening their interaction when managers engage in accrual-based manipulation. These findings highlight that tax avoidance in state owned enterprises is driven more by accounting discretion than by capital structure decisions, emphasizing the need for stronger oversight of financial reporting quality to reduce the risk of tax avoidance.
