Abstract

This study investigates the impact of Environmental, Social, and Governance (ESG) performance and board size on firm profitability. ESG practices have become increasingly important as companies attempt to balance financial performance with social responsibility and sustainable development. The objective of this study is to examine whether ESG performance and board size influence firm profitability measured by Return on Assets (ROA). The study uses panel data collected from publicly listed firms with a total of 386 firm-year observations. Data were analyzed using panel regression techniques with control variables including firm size, leverage, and growth. The results indicate that ESG performance has a positive and significant impact on firm profitability. Companies that actively implement ESG practices tend to achieve better financial outcomes due to improved stakeholder relationships, enhanced reputation, and better risk management. Furthermore, board size is found to positively influence profitability, suggesting that larger boards may provide broader expertise and stronger monitoring mechanisms that enhance managerial decision-making. The findings contribute to the literature on corporate sustainability and governance by demonstrating that ESG engagement and board structure play an important role in improving financial performance. The study also provides practical implications for corporate managers and investors by highlighting the strategic importance of ESG integration and effective board composition in achieving sustainable profitability.

Abstract

In the current digital era, public services are increasingly being transformed through technology, including tax administration systems. One of the major innovations implemented by the Indonesian government is the Core Tax System, an integrated tax administration system designed to improve service efficiency, data integration, and taxpayer compliance monitoring. This study aims to analyze the effect of Core Tax System implementation on taxpayer compliance in Indonesia. The research adopts a quantitative approach using primary data collected through questionnaires distributed to taxpayers. The collected data were tested using validity and reliability tests and analyzed through descriptive statistics and significance testing to examine the relationship between the research variables. The results indicate that the implementation of the Core Tax System has a positive and significant effect on taxpayer compliance, both partially and simultaneously. These findings suggest that tax system digitalization can serve as an important instrument in improving taxpayer compliance in Indonesia.

Abstract

Penelitian ini bertujuan untuk menguji secara empiris pengaruh kinerja keuangan yang diproksikan melalui Return on Assets (ROA) dan green accounting yang diukur melalui peringkat PROPER terhadap penghindaran pajak (Effective Tax Rate) pada perusahaan indeks LQ45 periode 2023–2024. Studi ini dilatarbelakangi oleh fenomena kontraksi penerimaan PPh Badan nasional sebesar 18,1% pada akhir tahun 2024 yang dipicu oleh penurunan laba korporasi serta indikasi agresivitas pajak pada emiten elit. Dengan menggunakan pendekatan kuantitatif dan teknik purposive sampling, diperoleh sampel sebanyak 32 perusahaan (64 unit observasi) yang dianalisis melalui model regresi linear berganda. Pengujian asumsi klasik menunjukkan bahwa residual terdistribusi normal (p=0,200), terbebas dari multikolinearitas (VIF=1,000), dan homoskedastisitas, meskipun terdapat gejala autokorelasi positif (DW=0,974). Hasil penelitian secara parsial mengungkapkan bahwa green accounting berpengaruh negatif signifikan terhadap ETR (p=0,028), yang mengindikasikan bahwa komitmen lingkungan perusahaan berkorelasi dengan peningkatan intensitas penghindaran pajak secara legal melalui biaya pengurang penghasilan bruto. Sebaliknya, kinerja keuangan terbukti tidak memiliki pengaruh signifikan terhadap penghindaran pajak (p=0,375), menyiratkan bahwa profitabilitas bukan merupakan pendorong utama manajemen pajak bagi emiten LQ45 demi menjaga legitimasi di mata investor. Secara simultan, integrasi kedua variabel tersebut tidak berpengaruh signifikan (p=0,060) dengan nilai Adjusted R Square sebesar 5,8%. Penelitian ini memberikan kontribusi bagi regulator dalam merumuskan kebijakan pajak hijau yang lebih spesifik guna memitigasi risiko tax gap pada korporasi besar.
