LITERATURE REVIEW 1 Tax Harmonization and Global Trends Tax harmonization is essential for aligning tax policies across jurisdictions to A mitigate the adverse effects of tax competition, such as the "race to the bottom" in tax rates. This is particularly important in a globalized economy, where multinational corporations can exploit tax regime differences to minimize liabilities, eroding national tax bases. The OECD's Base Erosion and Profit Shifting (BEPS) project is a key effort to establish minimum global tax standards to curb these practices . In the European Union, harmonization of indirect taxes like VAT has progressed, but corporate tax harmonization remains incomplete due to differing national interests . Proposals such as the Common Consolidated Corporate Tax Base . TB) aim to unify corporate tax frameworks . The OECD's BEPS project promotes transparency and fairness globally, advocating for tax rates that counteract tax competition . However, critics argue that tax harmonization can favor wealthier nations, limiting fiscal policy autonomy for developing countries . , . In Indonesia, efforts to align with international tax norms aim to modernize its tax system, though balancing domestic needs with global standards remains a challenge . This highlights the need for a balanced approach to tax harmonization, one that considers the socio-economic developing countries like Indonesia. 2 Fiscal Justice and Equity in Taxation Fiscal justice, involving the fair distribution of tax burdens, is a critical element of tax policy, particularly in Indonesia. Achieving fiscal justice requires addressing both vertical equities, where wealthier individuals and corporations pay more, and horizontal equity, ensuring that people in similar economic circumstances are taxed similarly . However, challenges such as tax evasion, avoidance, and regressive tax systems, which disproportionately burden low- and middle-income earners, complicate this pursuit .

METHODS 1 Research Design This study adopts a descriptiveanalytical approach, combining legal analysis with socio-economic data to examine the effectiveness and implications of Law No. 7 of The research is structured into two main components: first, a jurisdictional legal analysis, which involves a qualitative review of legal texts, including Law No. 7 of 2021, relevant tax regulations, international treaties, and judicial rulings. This analysis identifies key provisions of the law, assesses their alignment with international tax standards, and evaluates their potential impact on tax administration and fiscal justice in Indonesia. Second, an empirical analysis is conducted, quantitatively assessing tax-related data such as compliance rates, tax revenue collection, and socio-economic indicators before and after the law's implementation, to measure its effectiveness in improving tax compliance, promoting fiscal fairness, and supporting economic growth. The combination of legal analysis and empirical data provides a Vol. No. October 2024: pp. West Science Law and Human Rights comprehensive understanding of the law's jurisdictional and socio-economic impacts. 2 Data Collection Methods The data for this research was collected from a variety of primary and documents, government reports, academic literature, and socio-economic data. Legal documents, such as the full text of Law No. of 2021, relevant Indonesian tax laws, publications, were analyzed to understand the legal framework of the law. Government reports and publications from bodies such as the Indonesian Ministry of Finance and the Directorate General of Taxes provided quantitative insights into tax compliance, revenue collection, and the socio-economic impacts of the law. Academic literature, including scholarly articles, books, and policy papers, was reviewed to explore the theoretical and practical implications of tax harmonization and fiscal justice, offering context for evaluating the lawAos alignment with global tax trends and its potential to promote equity in IndonesiaAos tax system. Additionally, socio-economic data from sources like the Indonesian Central Statistics Agency (BPS). World Bank, and OECD, including indicators of income distribution, tax burdens, and economic inequality, were used to assess the broader impacts of the law on fiscal justice in Indonesia. 3 Analytical Techniques The collected data was processed and First, a legal analysis was conducted using a doctrinal approach, focusing on statutory interpretation, case law, and taxation-related legal principles to examine the provisions of Law No. 7 of 2021. This analysis assessed the law's consistency with international tax standards and its potential to address issues like tax avoidance, evasion, and fiscal inequality. Second, a comparative analysis was performed to evaluate IndonesiaAos tax system to other countries' tax regimes, identifying where IndonesiaAos approach to tax harmonization A aligns with or diverges from global best practices, particularly in promoting fiscal RESULTS AND DISCUSSION 1 Tax Compliance and Enforcement Law No. 7 of 2021 aims to improve tax compliance through stricter enforcement and clearer guidelines, leading to a significant increase in the number of registered This success was driven by key initiatives such as the Taxpayer Amnesty Programmed, stiffer sanctions for noncompliance, and digitalization of tax services . The amnesty programmer incentivized taxpayers to disclose previously undeclared assets without severe penalties, resulting in more than 20% new registrations from individuals and companies previously engaged in tax evasion . Strengthened sanctions, including higher fines and longer prison sentences, have led to a 10% decrease in cases of deliberate tax evasion in the first year . In addition, the digitalization of tax services has simplified the tax filing process, with around 80% of taxpayers now using online systems, improving efficiency and transparency in tax collection .

These challenges include a lack of understanding of the new tax provisions and limited access to digital tax services . 2 Fiscal Equity and Fairness Fiscal justice is a key theme of Law No. 7 of 2021, and the findings suggest that the law has made significant strides in promoting a fairer tax system. Law No. 7 of 2021 in Indonesia introduced significant reforms aimed at promoting fiscal justice through progressive taxation measures, including changes to the income tax structure, the introduction of a carbon tax, and adjustments to the Value Added Tax (VAT).

The law revises income tax rates, increasing the rates for higher earners, while maintaining lower rates for lower earners. a result, the top 10% of income earners now contribute a larger share of total tax revenue, increasing from 65% to 72% in the first-year post-implementation . , which supports vertical equity by ensuring that individuals with greater financial capacity contribute more proportionally. In addition, the carbon tax is an important step towards environmental sustainability, by levying a fee on carbon emissions and holding polluting industries accountable. In its first year, the carbon tax generated around IDR 12 trillion (USD 800 millio. , with funds allocated to environmental programmers and sustainable development projects . VAT adjustments included an increase in the standard rate and changes to exemptions, while exemptions for basic necessities such as food and healthcare were retained to mitigate the impact on lowincome households . , balancing revenue needs with minimizing the tax burden on vulnerable populations . , . Despite these positive outcomes, there are concerns regarding the regressive nature of certain indirect taxes, such as VAT. While the law seeks to protect low-income households through targeted exemptions, some experts argue that the overall tax burden on middle-income earners has increased. This points to the need for further refinement of the tax structure to ensure that fiscal equity is achieved across all income groups. 3 Revenue Collection and Economic Impact Law No. 7 of 2021 has had a noticeable impact on Indonesia's revenue collection efforts. Provisions in the law aimed at broadening the tax base and improving compliance have increased tax revenue. Law No. 7 of 2021, known as Harmonization of Tax Regulations (HPP), has had a significant impact on Indonesia's tax revenue by broadening the tax base and improving compliance, leading to a 12% increase in tax revenue in its first year. The law aims to optimize state revenue and create a fairer tax system, with the integration of the National Identification Number (NIK) into the Taxpayer Identification Number (NPWP) simplifying tax administration and improving efficiency . , . A key aspect of the law's impact was the increase in the tax base, facilitated by the tax amnesty programmer and improved compliance measures, which resulted in a substantial increase in the number of registered taxpayers, especially among those who previously evaded taxes. Revenue from new taxpayers accounted for about 25 per cent of the overall increase in tax revenue, underscoring the effectiveness of these efforts . Moreover, the increase in tax revenue has enabled the government to allocate more funds for infrastructure development, social welfare programmers, and environmental preservation, contributing to economic stability and growth . These strengthened public trust in the tax system and fostered a sense of shared responsibility for national development . However, challenges remain to ensure the sustainability of these achievements, as policymakers express concern over the potential weakening of compliance efforts over time. Small and medium-sized enterprises (SME. have also raised concerns about the complexity of the new tax rules, which may hinder their ability to fully comply with the law . 4 Alignment with International Standards Law No. 7 of 2021 aims to align Indonesia's taxation system with international standards by focusing on tax transparency, anti-avoidance measures, and environmental taxation, marking significant advancements that enhance the country's global tax The law incorporates the OECD's Base Erosion and Profit Shifting (BEPS) framework to prevent profit shifting by multinationals to low-tax jurisdictions . strengthens transfer pricing rules and requirements, thereby improving information exchange agreements with other countries, which enhances Indonesia's position in global Vol. No. October 2024: pp. West Science Law and Human Rights tax transparency rankings and reflects its commitment to international tax standards.

Furthermore, the law emphasizes cooperation in including the exchange of tax information and anti-money laundering measures, which are expected to enhance Indonesia's ability to combat tax evasion and contribute to a fairer global taxation system . , . CONCLUSION Law No. 7 of 2021 on Harmonization of Tax Regulations marks a critical step in modernizing IndonesiaAos tax system. The law has succeeded in broadening the tax base, improving compliance, and aligning the countryAos tax policies with global standards. Key achievements include the introduction of progressive tax measures, such as higher income tax rates for the wealthy and a carbon tax aimed at environmental sustainability. These reforms have improved revenue collection and contributed to fiscal justice by distributing the tax burden more equitably. However, the research highlights several challenges that must be addressed to ensure the lawAos long-term success. While larger corporations have adapted well to the new regulations, smaller businesses and individuals, particularly those in rural areas, face difficulties in compliance due to a lack of understanding and access to digital tax Additionally, concerns about the regressive nature of certain indirect taxes, such as VAT, remain, indicating a need for further policy adjustments. The alignment with international standards, particularly in areas like tax transparency and anti-avoidance measures, strengthens IndonesiaAos position in the global tax landscape. However, sustained efforts are needed to ensure that the lawAos benefits are equitably distributed and that all sectors of the economy are supported in complying with the new regulations. Future reforms should focus on simplifying compliance processes and addressing the challenges faced by SMEs to fully realize the goals of fiscal justice and economic sustainability in Indonesia.
