Taxes are the primary source of state revenue and play an essential role in financing national development. Indonesia’s taxation system adopts a self-assessment system, under which taxpayers are entrusted with calculating, paying, and reporting their tax obligations through the Tax Return (SPT). However, in practice, violations such as late filing, inaccurate reporting, and failure to submit tax returns are still frequently found, potentially causing losses to state revenue. This study aims to analyze the regulations governing tax return submission within Indonesia’s taxation system and the legal implications of incorrect tax return submissions based on the Decision of the Semarang District Court Number 608/Pid.Sus/2025/PN Smg. This study employs a normative legal research method using statutory and case approaches. Legal materials were collected through library research and document analysis and were subsequently analyzed qualitatively. The results indicate that tax return submission is regulated under the General Provisions and Tax Procedures Law, which requires tax returns to be completed correctly, comprehensively, and clearly. Violations involving intentional conduct and causing state financial losses may result in criminal sanctions as an ultimum remedium. The case examined demonstrates that tax return submission is not merely an administrative obligation but also carries legal consequences to maintain taxpayer compliance and state revenue.

Zakat and taxation are two important instruments in the life of society and the state, both of which aim to improve social welfare. However, in practice, the integration of zakat and taxation in Indonesia has not yet been fully realised, meaning that the potential of zakat as part of fiscal policy has not been optimally utilised. This study aims to examine the status of zakat within the legal system and public policy, the form of its integration into the tax system, and the various obstacles encountered in its implementation. This study employs a normative legal methodology using legislative, conceptual, and analytical approaches, and utilises secondary data analysed qualitatively. The research findings indicate that zakat has been recognised within the national legal system; however, it is still viewed as a religious obligation that coexists alongside taxation as a state obligation. The current integration remains limited to reductions in taxable income and has not yet demonstrated comprehensive coherence within fiscal policy. Furthermore, its implementation continues to face various obstacles from legal, institutional, technical, and fiscal perspectives, meaning it has not yet been effectively implemented.

Market levies are a regional taxation category that holds significant promise for increasing regional fiscal resources, complementing local tax revenues. The objectives of this study are; (1) Understanding the Communication Mechanism in the Implementation of Market Service Fee Policy in Gorontalo City. (2) Examination of Resource Availability in the Implementation of Market Service Tax Policy in Gorontalo. (3) Understanding the Bureaucratic Framework in the Implementation of Market Service Tax Policy in Gorontalo City. (4) Examination of the Implementation of Market Service Tax Policy Disposition in Gorontalo City. The method used in this study is a descriptive qualitative method. The results of this study indicate that the communication of market service fee policy has been carried out through systematic formal channels and is supported by a clear bureaucratic structure and division of tasks, but its implementation is still not optimal. This is caused by several obstacles, including unequal understanding and distribution of information among traders, limited resources in terms of both quantity and quality of human resources, budget, and inadequate market facilities. Furthermore, weak coordination and suboptimal implementation of SOPs in the field also impact work consistency, while the disposition or attitude of implementers who have demonstrated commitment but are not yet unified requires a more comprehensive strategic approach. Therefore, integrated efforts are needed, including improving the communication framework, strengthening human resource capacity, improving facilities, stricter supervision, and ongoing coaching to create more effective and professional policy implementation.

Indonesia's tax bureaucracy reform has entered a critical phase with the launch of the Core Tax Administration System (Coretax) by the Directorate General of Taxes (DGT) on December 31, 2024, formally implemented in January 2025. Designed to integrate all taxation processes into a single digital platform, Coretax represents the most ambitious digital transformation in Indonesian tax administration history. However, its early implementation revealed significant technical and institutional obstacles that undermined its intended efficiency gains. This study aims to analyze the barriers to Coretax implementation within the framework of Indonesia's tax bureaucracy reform. Using a qualitative case study method with semi-structured interviews and documentation techniques, data were collected from DGT officials and analyzed through George C. Edwards III's policy implementation theory, encompassing four variables: communication, resources, disposition, and bureaucratic structure. The findings reveal that implementation barriers are multidimensional: communication gaps stem from uneven digital literacy among users; resource readiness claims do not fully reflect real field capacities; institutional framing obscures variation in staff adaptation; and bureaucratic fragmentation impedes coordinated responses across units. These four variables operate simultaneously and reinforce one another, producing systemic institutional dysfunction that hinders optimal Coretax implementation

Inequality in Indonesia remains significant, particularly due to the concentration of wealth among high-net-worth individuals (HNWIs). Emphasizing the importance of addressing this disparity can motivate policymakers to pursue equitable solutions, thereby promoting social justice through wealth taxation. Using a literature review and an empirical legal approach, this research analyzes relevant regulations, policy discussions, and academic literature on wealth taxation in Indonesia. The study also evaluates institutional readiness and potential challenges in implementing such a policy. The results indicate that the wealth tax has considerable revenue potential, ranging from IDR 54 trillion to IDR 155.3 trillion, depending on the tax model applied. Highlighting this potential can empower policymakers and foster optimism about the tangible benefits of implementing such a policy.

Digital transformation has become a key catalyst in the reform of tax administration in the data-driven economy era. This study aims to analyze the role of digital transformation and fiscal incentives in enhancing taxpayer compliance, with tax literacy serving as a significant reinforcing variable. A quantitative approach was employed using primary data collected through questionnaires distributed to active taxpayers in Indonesia. Multiple linear regression analysis was applied to examine the relationship between digital transformation, fiscal incentives, tax literacy, and taxpayer compliance. The findings reveal that digital transformation has a positive and significant impact on improving taxpayer compliance by enhancing efficiency and transparency within the tax administration system. Fiscal incentives were also found to be effective in encouraging compliance motivation, particularly when integrated with digital systems that simplify tax reporting and payment processes. Moreover, tax literacy plays a strong mediating role, amplifying the effects of digital transformation and fiscal incentives on compliance behavior. These results confirm that successful tax reform in the digital era depends not only on technological infrastructure but also on improving taxpayers’ awareness and understanding of fiscal responsibility. This study provides both theoretical and practical contributions to the development of adaptive, transparent, and sustainable national fiscal policies. It recommends that the government strengthen the integration of the national digital tax system, develop data-based tax literacy programs, and refine fiscal incentive designs to more effectively promote long-term taxpayer compliance.

This study examines the implementation of the advertising tax policy and its role in supporting Regional Original Income (PAD) in Gresik Regency, and identifies barriers that affect its effectiveness. This research adopted a qualitative descriptive approach with data obtained from field studies involving key government officials and supported by relevant literature and regulatory documents. Data were analyzed using McNabb's (2002) framework, which includes grouping data based on constructs, identifying the basis for interpretation, developing generalizations, testing alternative interpretations, and refining theoretical insights. The results indicate that the implementation of the advertising tax policy in Gresik focuses more on intensification than extensification, as intensification is considered more practical and faces less resistance. The licensing and collection processes for advertising tax are carried out based on the legal framework of Regional Regulation No. 8 of 2023 concerning Regional Taxes and Levies and Regent Regulation No. 79 of 2023, which regulates the rental value of advertising as the basis for taxation. Despite significant revenue potential, significant challenges remain, such as inter-agency coordination issues, inadequate data collection, and technical and non-technical barriers in implementing this policy. Unclear legal sanctions and low public awareness and compliance are also inhibiting factors. Nevertheless, advertising tax revenue has generally reached its target, although certain periods were affected by unfavorable economic conditions. This study concludes that to maximize the contribution of advertising tax to local revenue (PAD), improved inter-agency coordination, strengthened institutional capacity, clarified regulatory sanctions, and enhanced public education and engagement are needed. This is expected to support regional fiscal independence in Gresik Regency.

Taxation contributes to national development, and Indonesia has responded to global dynamics by introducing Indonesia Core Tax, a digital system designed to improve tax transparency and compliance. Although Indonesia has adopted various digital systems such as e-Faktur and e-Invoicing, it still faces implementation challenges, while Malaysia is more advanced with its integrated and phased API-based e-Invois system. This study examines taxation policy within the framework of Indonesia Core Tax, focusing on the legal aspects of e-Invoicing implementation as part of the digital transformation of tax administration. The analysis covers the hierarchy and functions of legislation, from laws and regulations to Minister of Finance regulations (PMK) and technical regulations of the Directorate General of Taxes (DJP). This study uses a normative legal research method with a legislative approach and a comparative approach to compare Indonesia's digital taxation system with Malaysia's, covering legal structure, legal substance, and legal culture. The results of the study show that although Indonesia has a fairly complete digital legal framework, the implementation of the e-Invoicing system still faces challenges in terms of regulatory consistency and technological readiness. In contrast, Malaysia has already implemented a mandatory and centralized API-based e-Invoice system through a clearance model approach. This study recommends harmonizing digitalization policies in taxation and strengthening the legal system as strategic steps toward more effective and adaptive tax administration.

This study aims to analyze how negative and positive externalities influence the effectiveness of public economic policies at the regional level. Using a qualitative approach and descriptive-analytical method, the research was conducted in Tanjungpinang City through document studies, focus group discussions (FGDs), and content analysis of policy documents and scholarly literature. The findings reveal that negative externalities such as environmental pollution, traffic congestion, and industrial waste have not been optimally addressed due to weak regulation and limited policy evaluation. Conversely, positive externalities like the development of green open spaces and the provision of public education lack adequate fiscal support. Public policy interventions are predominantly disincentive-based, such as taxation and sanctions, while mechanisms to incentivize socially beneficial activities remain limited. These findings are examined through the lenses of Pigouvian Tax and Coase Theorem, emphasizing the need for evidence-based policies that internalize externalities fairly and efficiently. The study recommends improving regulatory frameworks, implementing strategic fiscal incentives, and enhancing public literacy in externality management.

This research conducts a juridical analysis of the problematic implementation of income tax on digital economic activities within Indonesia's taxation system. Digital transformation has altered the global economic landscape, yet the existing tax system has not fully accommodated the specific characteristics of the digital economy. This study aims to identify weaknesses in the income tax legal framework within the digital economy context and formulate an ideal construction for income tax regulation that can optimize tax revenue without impeding digital economic growth. The research employs a normative juridical methodology with statute approach, conceptual approach, and comparative approach. The findings indicate that current income tax provisions are ineffective in addressing digital economy challenges, particularly concerning concepts of income sources, permanent establishment, and monitoring mechanisms. The study recommends comprehensive reforms including redefinition of fundamental tax concepts, strengthening of the withholding tax system, development of tax information technology infrastructure, and harmonization with international standards. The ideal construction of income tax regulation must consider principles of legal certainty, fairness, administrative efficiency, and economic neutrality to create a taxation system adaptive to digital economic developments.

This study aims to analyze the challenges in implementing e-Samsat as a form of digitalization of motor vehicle tax services in Jakarta. E-Samsat is an information technology-based public service innovation designed to simplify the online tax payment process, improve the efficiency of public services, and support local government transparency and accountability. This research uses a descriptive qualitative method with a literature study, which examines various sources such as scientific journals, policy reports, and related articles. The results show that challenges in implementing e-Samsat can be categorized into internal and external challenges. Internal challenges include limited technological infrastructure, weak system integration between agencies, dependence on one bank partner, and concerns over data security. Meanwhile, external challenges include the low digital literacy of the community, the lack of government socialization, and the tendency of the community to continue using conventional methods or intermediary services. This research confirms that the successful implementation of an online tax system depends not only on technological readiness, but also on the government's active role in building digital education and strengthening cross-sector collaboration. An adaptive and participatory policy approach is needed so that this program can embrace all levels of society, especially groups that are not familiar with online taxation.

Public service delivery in taxation is a vital function of government in fulfilling citizens' administrative rights, particularly through the issuance of the Taxpayer Identification Number (NPWP). The quality of this service directly influences taxpayer satisfaction, understanding, and trust in tax institutions. This study aims to analyze the quality of public service in NPWP issuance at the Primary Tax Office (KPP Pratama) of Dumai City and to identify supporting and inhibiting factors affecting service implementation. This research employed a descriptive qualitative approach. Data were collected through observations, in-depth interviews with tax officers and taxpayers, and documentation studies. Data analysis was conducted using an interactive model consisting of data reduction, data presentation, and conclusion drawing. The assessment of service quality was based on the SERVQUAL framework developed by Zeithaml and Parasuraman, encompassing five dimensions: tangibles, reliability, responsiveness, assurance, and empathy. The results show that NPWP issuance services at KPP Pratama Dumai City are generally well implemented. Adequate facilities, adherence to standard operating procedures, responsive officers, data security assurance, and courteous service attitudes support service quality. However, challenges remain, particularly related to limited waiting room capacity during peak periods, varying levels of taxpayer understanding, and the need for clearer procedural information. Continuous improvement in communication, service management, and capacity planning is required to enhance public service quality.

This study aims to analyze the implementation of e-commerce tax in Indonesia from the perspectives of law and enforcement effectiveness. Using a normative juridical approach, this research examines the legal norms outlined in legislation, including Law No. 11 of 2008 on Electronic Information and Transactions (as amended), Law No. 7 of 2014 on Trade, and Minister of Finance Regulation No. 210/PMK.010/2018. The findings indicate that e-commerce requires specific regulations due to its unique characteristics compared to conventional trade. These regulations aim to protect consumers and ensure tax compliance. However, challenges in implementing these regulations persist, particularly in supervision and law enforcement. Furthermore, the taxation aspect of e-commerce faces difficulties in reaching international businesses and avoiding tax evasion. Therefore, ongoing efforts from the government are necessary to strengthen regulations and law enforcement in addressing the dynamics of e-commerce development in Indonesia, to achieve legal certainty and optimal tax contributions from this sector.
