This study examines Income Tax provisions under the latest tax regulations in Indonesia, explains the procedures and mechanisms for calculating Income Tax based on the Law on Harmonization of Tax Regulations (HPP Law), and evaluates the contribution of Income Tax to state revenue and equitable income distribution. This research applies library research with a qualitative descriptive approach. The data were collected from relevant sources, including laws and regulations, academic books, scientific articles, research journals, and official government publications related to Income Tax policy in Indonesia. The data were analyzed systematically to identify regulatory developments, tax calculation mechanisms, and the implications of tax policy for national state revenue and fiscal justice. The findings show that the HPP Law establishes five progressive tariff layers for Individual Taxpayers, with a maximum rate of 35% imposed on taxable income exceeding IDR 5 billion per year. This provision reflects the principles of ability to pay and vertical equity in Indonesia’s tax system. Furthermore, the Corporate Income Tax rate of 22%, along with various rate-reduction incentives for eligible taxpayers, can enhance business competitiveness and reduce tax burdens. Tax administration modernization through e-Filing, e-Billing, e-Bupot, and Coretax also improves service efficiency and strengthens taxpayer compliance more effectively.

The digitalization of tax administration has become one of the Indonesian government's strategic initiatives to improve efficiency, transparency, and taxpayer compliance. However, the implementation of digital tax systems among Micro, Small, and Medium Enterprises (MSMEs), particularly distributor-sector MSMEs in Batam City, still faces various administrative and technical challenges. This study aims to examine the experiences, risk perceptions, and adaptation strategies of distributor MSME actors in responding to the digitalization of tax administration following the implementation of the Harmonization of Tax Regulations Law (UU HPP). The research employed a qualitative approach using a phenomenological method. Data were collected through in-depth interviews with seven distributor MSME owners in Batam City who had utilized digital tax systems such as e-Filing and Coretax. The findings indicate that most business actors still experience limitations in technical understanding, concerns regarding reporting errors, and difficulties adapting to changes in digital tax systems and regulations. To address these challenges, MSME actors developed several adaptation strategies, including the use of tax consultants, hybrid manual-digital bookkeeping systems, and informal assistance through the internet and business networks. This study highlights that the success of tax digitalization requires a more adaptive approach, stable systems, and policies that are aligned with the characteristics of local MSMEs.

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 results indicate that the developed sistem is capable of automating salary calculations, allowances, deductions, tax computations, and report generation in an integrated and structured manner. The sistem also reduces manual errors, minimizes redundancy, and accelerates payroll administration processes. Therefore, the proposed information sistem can significantly enhance the performance, productivity, and service quality of the HR and finance departments at PT Infokom Internusa.

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.

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.

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.

Digital transformation in the public sector has become a strategic agenda to improve the efficiency, transparency, and quality of government services, including in regional revenue management. This study aims to analyze the implementation of digital transformation in the Regional Revenue Agency (Bapenda: Badan Pendapatan Daerah) of East Java Province, especially in the Gresik Technical Implementation Unit (UPT: Unit Pelaksana Teknis), as well as its impact on administrative efficiency, transparency, and increasing Regional Original Revenue (PAD: Pendapatan Asli Daerah). This study uses a non-empirical qualitative approach with a literature study method, which involves the analysis of secondary data from scientific journals, policy documents, government performance reports, and community digitalization indicators such as the Indonesian Digital Society Index (IMDI: Indeks Masyarakat Digital Indonesia). The results show that digital transformation through e-payment systems and web-based administration has significantly accelerated the service process, improved taxpayer compliance, and reduced revenue leakage. The receipt of PAD through digital channels increased by 60% in one year, while service efficiency increased by reducing administrative process time from three days to one day. The implementation of this digital transformation is also influenced by the readiness of infrastructure, apparatus competence, and community digital literacy, as described in the theoretical framework of the Technology Acceptance Model (TAM), Dynamic Capabilities, and TOE Framework. Despite positive achievements, challenges such as digital skills gaps, resistance to change, and system security issues are still obstacles in optimizing digital transformation. This research makes a theoretical contribution to the development  of e-governance literature  and digital public policy practices at the local level. These findings also provide concrete recommendations for other regions to replicate good practices of digital transformation that have succeeded in improving regional financial performance. Thus, digital transformation is not only a technological instrument, but also a governance strategy that requires synergy between technology, organizations, and society

This study explores the contribution of regional taxes and levies to Regional Original Revenue (PAD) in Surabaya City and their role in fostering fiscal independence within the framework of regional autonomy. Employing a descriptive qualitative approach, data were collected from the Surabaya City Regional Revenue Agency and relevant local government offices, complemented by secondary sources such as regulatory documents and literature on regional finance. The data analysis process followed McNabb’s (2002) framework, which consists of categorization, interpretation, generalization, testing alternative perspectives, and refining theoretical insights. The findings reveal that PAD acts as a crucial financial backbone for the implementation of regional autonomy, with taxes and levies serving as the primary contributors. On average, these sources accounted for 89.08% of the total PAD during the 2021–2024 period. The growth trend observed is driven by several factors, including the presence of a comprehensive legal and regulatory framework, diversification of tax types and structures, adequate institutional and human resource capacity, as well as increasing public awareness of tax obligations. Although there was a temporary decline in proportional contribution in 2023, overall tax and levy collections exceeded their targets, underscoring their vital role in supporting government administration and regional development programs. This study emphasizes the need for strengthening regulatory frameworks, enhancing administrative capacity, encouraging greater community participation, and optimizing the use of digital technologies to improve efficiency in revenue collection. These strategies are essential to reduce reliance on central government transfers and to promote greater fiscal independence for Surabaya City.

This community service activity was carried out as an effort to improve the effectiveness of reporting and withholding of Income Tax (PPh) Article 21 at the Kosayu Credit Cooperative through accounting-based technical assistance. The main problem identified during the Field Work Practice (PKL) activity was the potential for tax overpayments caused by inaccurate estimates of employee annual income and limitations of the payroll system used by the cooperative. To address these problems, the implementation team implemented several methods, namely direct observation of the tax administration process, technical training for related staff, tax calculation simulations based on actual data, and evaluation of the existing tax recording and reporting system. The results of the activity showed that although the cooperative had used the Average Effective Rate (TER) method for withholding PPh 21, its implementation was still not optimal because it was not supported by an integrated information system and a regularly updated employee database. This resulted in inaccuracies in tax calculations and withholding. Therefore, this assistance recommended several improvements, including updating the payroll system, improving employee data, integrating the digital tax reporting system, and increasing the capacity of the cooperative's human resources through ongoing training related to tax regulations. In addition to having a direct impact on the efficiency of cooperative tax management, this program also provides contextual learning benefits for students in linking tax accounting theory with real conditions in the field.
