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.

The rapid evolution of digital technologies has fundamentally reshaped tax administration systems, particularly for Micro, Small, and Medium Enterprises (MSMEs), which constitute a critical driver of economic development yet continue to demonstrate suboptimal levels of tax compliance. This study aims to critically examine the role of Application Programming Interface (API)-based tax automation in enhancing MSME tax compliance through a systematic narrative literature review approach. Employing a qualitative design, this study synthesizes recent scholarly works published within the last five years to identify patterns, relationships, and emerging trends in digital taxation practices. The findings indicate that API-based automation significantly improves administrative efficiency, minimizes human error, and facilitates real-time data integration between taxpayer systems and tax authorities. Moreover, such integration enhances transparency and reduces compliance costs, thereby fostering voluntary compliance behavior among MSMEs. Nevertheless, the effectiveness of this technological intervention is contingent upon several structural and behavioral factors, including digital literacy, technological readiness, and the availability of reliable digital infrastructure. Persistent disparities in these areas may constrain the scalability and inclusiveness of API implementation. This study underscores that API-based tax automation represents a transformative policy instrument in modernizing tax administration systems, provided it is supported by coherent regulatory frameworks, capacity-building initiatives, and equitable infrastructure development. The findings contribute to the broader discourse on digital taxation by offering a conceptual foundation for developing adaptive and sustainable compliance strategies in the era of economic digitalization

Taxpayer compliance is a key factor in optimizing state revenue, given that taxes are the primary source of funding for various national development programs. However, in practice, Indonesia still faces various challenges in improving taxpayer compliance, particularly among individual taxpayers, as indicated by the persistent gap between the number of registered taxpayers and those actively fulfilling their tax obligations. This situation indicates that increasing compliance does not solely depend on existing policies but is also influenced by various other internal and external factors. This study aims to analyze the factors influencing individual taxpayer compliance through a literature review approach, focusing on tax literacy, the use of information technology, and the implementation of the CoreTax Administration System (CTAS). The method used is to examine and synthesize various relevant previous studies to gain a more comprehensive understanding. The results of the study indicate that tax literacy plays a significant role in increasing taxpayer understanding and awareness, the use of information technology can provide convenience, efficiency, and accessibility in the tax process, while the implementation of CTAS contributes to increasing transparency and data integration within the tax administration system. Overall, these three aspects are interrelated and play a role in forming a more effective tax ecosystem in encouraging optimal and sustainable improvements in taxpayer compliance.

The implementation of the Global Minimum Tax (GMT) through Pillar Two of the OECD/G20 marks a fundamental change in the international tax architecture, especially for developing countries such as Indonesia. One of the key instruments in Pillar Two is the Qualified Domestic Minimum Top-Up Tax (QDMTT), which provides an opportunity for source countries to retain the right to tax the profits of multinational companies with an effective tax rate below 15 percent. This study aims to analyze Indonesia's readiness to face the implementation of GMT through the QDMTT policy, focusing on regulatory aspects and tax administration capacity. The research method uses literature studies with a qualitative-descriptive approach through the analysis of policy documents, tax regulations, as well as academic literature and international reports. The results of the study show that Indonesia's readiness is still in the transition stage. In terms of regulation, Indonesia has shown an initial commitment through the issuance of PMK Number 136 of 2024, but the regulation still needs to be strengthened at a higher level of regulation for long-term legal certainty. From the administrative aspect, the main challenges include the complexity of calculating jurisdiction-based Effective Tax Rates, cross-border data management, as well as increasing the capacity of human resources and information technology infrastructure. This study concludes that the success of QDMTT implementation in Indonesia depends on strengthening regulations, increasing tax administration capacity, and reformulating sustainable investment policies.

Tax administration reform is a strategic government agenda to improve the effectiveness, efficiency, and transparency of tax management. One effort undertaken is the implementation of an integrated, digital-based Core Tax Administration Sistem (Coretax). However, the success of Coretax implementation is determined not only by technological aspects, but also by the role of strategic management in planning, organizing, and managing organizational change. This study aims to examine the role of strategic management in supporting the successful implementation of Coretax as part of tax reform in Indonesia. The research method used is a literature review by examining various secondary sources such as scientific journals, international agency reports, government policy documents, and official publications related to tax reform and the digital transformation of the public sector. The results of the study indicate that strategic management plays a crucial role in aligning policies, human resource readiness, strengthening information technology, and managing resistance to change. These findings confirm that Coretax implementation will be more optimal if supported by comprehensive strategic planning, improved human resource competency, and an organizational culture that is adaptive to digital transformation.

State revenue holds a vital position in sustaining national development and the functioning of government, with taxation serving as the primary contributor to Indonesia’s State Budget (APBN). The substantial reliance on tax income obliges the government to manage the taxation system in an optimal, efficient, and sustainable manner. Nevertheless, the attainment of tax revenue targets in practice remains challenged by various issues, including structural, administrative, and strategic limitations. This study seeks to examine the role of strategic tax management in supporting the achievement of state revenue objectives. The research adopts a literature review approach by analyzing textbooks, national and international scholarly journals, official government publications, and relevant regulatory frameworks. The data are analyzed using a descriptive qualitative method through processes of classification, comparison, and synthesis of findings from previous studies. The findings reveal that strategic tax management has a crucial influence on enhancing state revenue performance through coherent policy formulation, flexible strategy execution, and ongoing performance assessment. The integration of information technology, the reinforcement of tax administration, and the improvement of taxpayer compliance emerge as key determinants in achieving revenue targets. Accordingly, strategic tax management constitutes a fundamental tool for ensuring fiscal resilience and promoting sustainable national development.

This study examines the implementation of the Coretax system in preparing electronic withholding tax slips (e-Bupot) and submitting Monthly Income Tax Article 21 (PPh 21) Returns at PT RSA. Coretax, launched by the Directorate General of Taxes (DGT) and officially implemented on January 1, 2025, is part of the government’s effort to modernize tax administration and improve taxpayer compliance. The research uses a qualitative descriptive method with a case study approach. Data were obtained through interviews with personnel responsible for PPh 21 administration, direct observation of e-Bupot preparation and monthly tax return filing through Coretax, and documentation review of tax reports and withholding slips. The analysis compares PT RSA’s practices with applicable tax regulations and identifies technical challenges during system use. The results show that PT RSA has complied with prevailing regulations, including the application of the Average Effective Rate (TER) and the utilization of Coretax for tax administration. However, technical constraints remain, particularly unstable internet connections and slow Coretax server performance during peak reporting periods, leading to data entry delays and upload failures. Therefore, improvements in system stability and performance are needed to support timely reporting and optimal tax compliance.

Taxes are the largest contributor to state revenue in financing national development. Tax compliance is the act of the taxpayer in fulfilling their tax obligations following the provisions of the legislation and tax implementation regulations in force in a country. Efforts made by the government to improve taxpayer compliance are by reforming tax laws and the tax administration system. This study aims to determine the effect of tax knowledge, tax sanctions, the benefit of the taxpayer identification number, and modern tax administration systems on personal taxpayer reporting compliance at the tax office in North Badung. The population of this research is personal taxpayers at the North Badung Tax Office Services, which is based on the data of individual taxpayers, as many as 95,542 people. The sample in this study consisted of 76 individual taxpayers who reported compliance, selected using a non-probability sampling method with an accidental sampling technique. The data analysis technique used is multiple linear regression analysis. The results showed that the tax knowledge variable did not affect personal taxpayer compliance, while the tax sanctions variable, the benefit of the taxpayer identification number, taxpayer awareness, and the modern tax administration system had a positive effect on personal taxpayer reporting compliance. Further research can expand on this study by incorporating other variables that, in theory, influence taxpayer reporting compliance, such as tax services.

Local governments in Indonesia rely significantly on local tax revenues to strengthen fiscal independence and sustain regional development. Among these revenue sources, the Motor Vehicle Tax (PKB) and the Motor Vehicle Transfer Fee (BBNKB) play a vital role in shaping regional fiscal capacity. This study explores how both taxes contribute to the Regional Own-Source Revenue (PAD) of Central Java Province during the 2020–2024 period. Drawing on quantitative analysis and secondary data from the Central Java Regional Revenue Agency (Bapenda), the research assesses the effectiveness and contribution of PKB and BBNKB in supporting local fiscal performance. The results show that PKB consistently exerts a positive, meaningful influence on PAD, underscoring its central role in sustaining the province’s fiscal strength. In contrast, BBNKB demonstrates a weaker, less stable impact, primarily driven by changes in vehicle ownership trends and administrative challenges. When considered together, both tax instruments contribute to enhancing local fiscal capacity, although the reliance on PKB remains predominant. These findings underscore the importance of modernizing regional tax administration, particularly through digital innovation, transparent reporting systems, and community-based compliance strategies. Strengthening these mechanisms is essential to building a more resilient and autonomous fiscal framework, especially in the context of post-pandemic economic recovery and long-term regional development planning

The digital era requires companies to adapt to modern, efficient, and accurate taxation systems. This study aims to analyze the implementation of an integrated system to optimize tax administration processes in a port service company in Indonesia. The focus of this research is to examine how the integration of systems such as SAP, Coretax, Microsoft Excel, and digital banking platforms is utilized to manage Income Tax Article 23 (PPh 23), Value Added Tax (VAT), and the tax reimbursement process. This study employs a qualitative approach with a descriptive case study design, conducted through participatory observation, document analysis, and informal interviews with employees directly involved in tax administration. The results indicate that the integrated system positively impacts the efficiency, consistency, and reliability of tax administration processes. It helps streamline workflows and accelerate tax reporting, particularly in managing PPh 23 and VAT. However, weaknesses remain in the manual data recap stage using Microsoft Excel, which is prone to human error due to the absence of automatic validation mechanisms. Therefore, this study recommends developing a standardized Excel template equipped with automatic validation features and providing training for staff to enhance data accuracy and administrative effectiveness. These findings are expected to serve as a practical reference for other companies in implementing an integrated taxation system that is optimal and sustainable, as well as encouraging increased efficiency and compliance with tax administration in the corporate environment.

The implementation of Coretax on taxpayers (clients) is able to provide an overview of how this application works and affects the taxpayer's compliance. This research aims to analyze the impact of Coretax application implementation on taxpayer compliance in AW&L Accounting Service Office (KJA) clients. The approach used in this research is descriptive qualitative. Collection of research data through literature studies, interviews and direct observations. Research results show that Coretax is able to simplify the tax reporting process through automation features, data integration, and comprehensive usage guidelines. The implementation of Coretax has a positive impact on taxpayer compliance. The obstacles found in the implementation of Coretax include low technology literacy, the need to provide additional education and training in the use of Coretax, and there are technical problems in the Coretax access system due to poor optimal signals. The improvement of the Coretax system by the Directorate General of Taxes is always updated in order to improve the tax administration system in Indonesia.

This study aims to examine the role of Coretax as a digital innovation in reporting the Periodic Tax Return (SPT Masa) for Income Tax Article 21 (PPh 21), which has been nationally implemented since 2025. Coretax is an integrated tax administration system developed by the Directorate General of Taxes to combine the processes of electronic withholding tax slip (e-Bupot) creation, tax return reporting, and tax payment into one efficient and accurate online platform. The system simplifies reporting procedures, accelerates administrative processes, and enhances taxpayer compliance through real-time data integration and automatic validation. However, the implementation of Coretax faces challenges such as technical issues, intensive training needs for staff at Tax Service Offices, and limited digital literacy among taxpayers, especially micro, small, and medium enterprises (MSMEs). This study provides an overview of Coretax’s contribution to supporting the digital transformation of Indonesia’s tax system while identifying obstacles that must be addressed to ensure optimal system performance.

This study aims to analyze the efficiency of issuing tax invoices and reporting Value Added Tax (VAT) Periodic Tax Returns (SPT Masa PPN) by comparing the DJP Online system and the Coretax Administration System at CV XYZ. The research focuses on comparing the reporting process before and after the use of the Coretax digital system, as well as evaluating its direct impact on the efficiency of VAT reporting for Taxable Entrepreneurs (PKP). A descriptive qualitative method was used, with data collected through observation and documentation. The results show that prior to using Coretax, tax reporting was conducted through two separate applications, e-Faktur and e-SPT, which led to inefficiencies, input errors, and longer processing times. After the implementation of Coretax, the reporting process became more integrated, automated, and time-efficient. The system also supports digital document archiving and offers automatic validation and notifications, thereby reducing the risk of delays and reporting errors. Although technical issues such as internet dependency, system errors, and user adaptation remain, Coretax overall has a positive impact on improving tax administration efficiency and compliance at CV XYZ.

The implementation of the core tax administration sistem (Core Tax Administration Sistem or Coretax) in early 2025, which was expected to modernise tax services, instead sparked a wave of public criticism due to various fatal technical obstacles. The dysfunction of this sistem not only hampered administration but also gave rise to discourse on distrust of state budget management. This study aims to analyse in depth how the failure to implement Coretax has eroded public trust and damaged the fiscal social contract between taxpayers and the state. The research method uses a qualitative approach with a Critical Discourse Analysis perspective based on Norman Fairclough's model. Data was collected through netnography from public comments and interactions on social media, then analysed through three dimensions: text (micro), discourse practice (meso), and social practice (macro). The findings show that public discourse is not merely technical complaints, but a form of symbolic resistance. At the micro level, sistem dysfunction is interpreted as evidence of incompetence and alleged budget irregularities. At the meso level, the public mobilises collective memory related to past government project failures to validate their distrust. At the macro level, this signifies a violation of the principle of reciprocity, whereby the state is perceived as demanding tax compliance without providing adequate services, thereby triggering a crisis of legitimacy. The implications of this study emphasise that digital transformation of the public sector requires transparency and accountability; failure to respond to this crisis has the potential to significantly reduce voluntary tax compliance.

The study aims to evaluate the adoption of the Coretax system by government expenditure treasurers using the Technology Acceptance Model (TAM). We assesses the factors influencing users' attitudes and intentions toward using new technology. Primary data from local government public service agencies in Karanganyar and Wonogiri regencies are collected by using questionnaire, analyzed with linear regression and path analysis. Our analysis reveals that perceived usefulness and behavioral intention are scored high, indicating that the treasurers find Coretax beneficial and are strongly inclined to continue using it. However, perceived ease of use and attitude toward use showed moderate to high ratings, indicating room for improvement in terms of ease of use and user comfort. Regression analysis found that perceived ease of use significantly affects perceived usefulness, attitude toward use, and behavioral intention. However, perceived usefulness and attitude toward use did not significantly influence behavioral intention. The findings suggest that the ease of use of Coretax plays a more crucial role in shaping the treasurers' behavioral intentions than perceived usefulness or affective attitude. This study providing insights into key determinants affecting user intentions and offering empirical foundations for developing training policies, system design improvements, and implementation strategies tailored to the public sector's needs. The findings of this research are also expected to contribute to offer practical implications for strengthening national tax digitalization reforms.

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 aims to analyze the impact of the implementation of digitalization policy in tax administration through e-Invoice, e-SKP, and e-Bupot systems on tax compliance in manufacturing industry companies, as well as to identify determinants of its effectiveness in enhancing compliance behavior in the era of digital transformation. A descriptive narrative literature review approach was employed, drawing on 52 articles published between 2014 and 2024 from international academic databases such as Google Scholar, ProQuest, and JSTOR. Thematic analysis was conducted to identify recurring patterns and theoretical connections related to digital tax administration and compliance in the manufacturing sector. The findings indicate that digitalization of tax administration has a significant positive impact on compliance, with compliance rates increasing by 42% and non-compliance decreasing from 28% to 12%. Five main pathways were identified: efficiency pathway, transparency pathway, integration pathway, technology acceptance pathway, and trust pathway. These pathways highlight how digital platforms streamline processes, strengthen accountability, facilitate data integration, improve user adoption, and enhance trust between taxpayers and authorities. Furthermore, digital literacy and infrastructure readiness emerged as critical moderators. Companies with high levels of digital literacy experienced a 58% improvement in compliance, whereas those with limited capabilities showed only a 23% increase. Theoretically, the study contributes to the development of a Digital Tax Compliance Model that integrates the Technology Acceptance Model with Tax Compliance Theory, offering a comprehensive framework to explain the complex interactions between technological, organizational, and environmental factors in the success of digital transformation. Practically, the results provide valuable insights for policymakers and tax authorities in designing responsive strategies that strengthen compliance in the manufacturing industry through sustainable digitalization initiatives.

This research is motivated by the phenomenon of declining compliance levels of motor vehicle taxpayers in Kediri Regency in the last five years, despite the provision of various modernization services. Motor vehicle tax itself is one of the main sources of regional revenue that is very important in supporting development and financing public services. This study aims to determine the effect of income levels, taxpayer awareness, and modernization of the tax administration system on motor vehicle taxpayer compliance in Kediri Regency in 2024. The research method used is quantitative with a causality approach. The population in this study were all motor vehicle taxpayers in Kediri Regency, with a sample of 100 respondents selected using probability sampling methods and simple random sampling techniques. Data analysis was performed using multiple linear regression with the help of the IBM SPSS Statistics program version 30. The results of the study indicate that partially, the variables of income level and taxpayer awareness have a significant effect on motor vehicle taxpayer compliance, while the modernization of the tax administration system has no significant effect. However, simultaneously, all three variables have a significant effect on motor vehicle taxpayer compliance. These findings demonstrate the importance of increasing awareness and community economic empowerment in encouraging tax compliance. Based on these findings, it is recommended that local governments and relevant agencies improve tax education and maximize the use of modern tax services to encourage higher public compliance. Furthermore, the results of this study indicate that despite the implementation of modernized tax administration systems, non-technical factors such as income level and taxpayer awareness still have a greater influence on motor vehicle taxpayer compliance. This suggests that improved technology and administrative systems alone are not sufficient to significantly improve tax compliance.
