Abstract: This study aims to examine the influence of taxpayer awareness, the PKB-BBNKB revenue-sharing policy . , and public service accountability on motor vehicle taxpayer compliance in the jurisdiction of the Regional Revenue Management of Cirebon Regency I Sumber.

Data are collected via questionnaires and analyzed using multiple linear regression with the help of SPSS 25. 0 software. The results indicate that taxpayer awareness has a positive and significant effect on motor vehicle taxpayer compliance, suggesting that better understanding and concern about tax obligations increase the likelihood of compliance. The implementation of the PKB-BBNKB opsen policy also shows a positive and significant effect, reflecting that fiscal decentralization through revenuesharing encourages local governments to improve tax collection systems and services, which in turn boosts taxpayer motivation. Furthermore. Additionally, public service accountability shows no significant impact. This insignificance may be due to the public's perception that public services are administrative and do not directly affect their decisions to comply with tax The simultaneous test (F-tes. confirms that the three independent variables collectively have a significant impact on taxpayer compliance.

INTRODUCTION In Indonesia, there are two primary types of taxes levied on the public: federal taxes and regional . Federal taxes are administered by the central government and allocated for national budget expenditures (APBN), whereas regional taxes are managed by provincial and local governments to finance regional needs (Dharmawan, 2024. Bapenda Jabar, 2. Among the various types of local taxes, the Motor Vehicle Tax (PKB) and the Vehicle Title Transfer Fee (BBNKB) contribute significantly to local revenue. The growing number of motor 2776 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 vehicles in West Java each year (BPS, 2. increases the potential tax revenue from this However, despite the promising revenue prospects, a considerable number of taxpayers remain non-compliant, as evidenced by the number of unrenewed vehicle registrations (KTMDU) in Cirebon Regency (Kantor Pusat Pengelolaan Pendapatan Daerah Wilayah Kabupaten Cirebon I Sumber, 2. Tax compliance is a crucial factor in boosting local revenue, especially with the implementation of the Opsen PKB-BBNKB policy, a new fiscal instrument introduced to enhance local tax collection (West Java Provincial Government Regulation No. 9 of 2. Factors such as taxpayer awareness and the accountability of public services provided by the Samsat office are considered to significantly influence compliance. Nevertheless, there remains a scarcity of comprehensive studies integrating these three variablesAitaxpayer awareness, opsen policy, and public service accountabilityAiwithin the context of PKB and BBNKB at the local level. Local taxes are among the main sources of income for regional governments, playing a vital role in funding development projects and public services. PKB is one of the most significant local taxes in terms of its contribution to Regional Original Revenue (PAD). Despite its high potential, ensuring taxpayer compliance with PKB remains a persistent challenge for revenue optimization (Kurniawan & Nugroho, 2. This issue is particularly evident in Cirebon Regency, specifically within the jurisdiction of the Regional Revenue Management Office (PPDPD) in Sumber, where high levels of tax arrears and low public enthusiasm for fulfilling tax obligations persist. Such non-compliance poses a threat to regional financial planning and undermines the effectiveness of public services, which are largely dependent on tax income (Rizal et al. , 2. Numerous studies have indicated that tax compliance is influenced not only by legal enforcement but also by behavioral factors, such as tax awareness, perceived fairness of the fiscal system, and the quality of services provided by government institutions (Torgler & Schaltegger, 2. In light of this, the current study explores three key determinants of motor vehicle tax compliance: taxpayer sensibilization . wareness and understandin. , the opsen policy as a fiscal optimization measure, and the accountability of tax-related public services First, taxpayer sensibilization refers to the extent to which individuals understand the importance of taxes for regional development and voluntarily fulfill their tax obligations. Greater awareness tends to correlate positively with tax compliance, fostering voluntary participation without coercion (Nuraini & Hafiz, 2. Second, the implementation of the revenue-sharing system . between provincial and local governments for PKB-BBNKB is expected to enhance compliance by creating fiscal incentives. Taxpayers are more likely to comply when they see that their contributions are reinvested into local development (Putri & Arifin, 2. Third, accountability in public service is essential to building trust in tax Fast, transparent, and fair services foster a positive public perception of the government and contribute to improved compliance (Susanti et al. , 2. The significance of PKB and BBNKB in contributing to local revenue is underscored in Law No. 28 of 2009. In practice, however, the collection of these taxes faces several obstacles, particularly in terms of taxpayer compliance. According to 2025 data from the Cirebon Regional Revenue Management Office, approximately 14% of registered taxpayers have not renewed their vehicle registrations. This reveals a gap between the potential and actual tax revenue, largely attributed to taxpayer non-compliance and limited awareness regarding their fiscal responsibilities and the benefits of taxation (Sari & Kusuma, 2. In addition, negative perceptions about the quality of public services especially those offered by Samsat and local tax offices discourage taxpayers from fulfilling their obligations. Research by Wulandari . and Dewi . identified poor transparency, complicated bureaucracy, and long waiting times as barriers that reduce taxpayer willingness to comply. 2777 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 Against this backdrop, the present study aims to analyze the determinants of motor vehicle taxpayer compliance, focusing on three variables: taxpayer awareness, the PKbNKB opsen policy, and the accountability of public services. Unlike previous research that has largely focused on awareness and transparency alone (Prayitna & Witono, 2022. Dewi, 2. , this study incorporates the relatively new fiscal policy of opsen PKB-BBNKB, which seeks to enhance regional tax revenue, and considers the impact of public service accountability in fostering trust and compliance (Wulandari, 2022. Bapenda Jabar, 2. The study thus contributes novel insights by integrating fiscal policy and public service management perspectives in the context of motor vehicle tax compliance. Theoretically, this research enriches the literature on tax compliance behavior by introducing opsen policy and service accountability two variables rarely studied together. Practically, it is expected to offer strategic recommendations for local governments, particularly Bapenda and Samsat, to strengthen tax compliance through enhanced public awareness, optimization of the opsen policy, and improvements in transparent and responsive service delivery. Prior studies have shown a significant positive relationship between taxpayer awareness and compliance (Rakhmadhani, 2020. Pranata et al. , 2. However, other studies report inconsistent findings regarding the impact of awareness and tax rates (Karlina & Ethika. Putra, 2. Meanwhile, research on the effectiveness of the PKB-BBNKB opsen policy remains limited, even though it has already been implemented and contributed significantly to local revenues (Fitriana, 2024. Rachmawati, 2. Likewise, few studies have examined the role of public service accountability in motor vehicle tax compliance (Prayitna & Witono. Therefore, this study addresses these research gaps by analyzing all three variables Based on the findings, this research recommends that local governments intensify tax awareness campaigns and educational initiatives, expand and optimize the use of the PKB-BBNKB opsen to enhance revenue and compliance, and improve the quality of public services by emphasizing accountability, transparency, and responsiveness. These efforts are expected to boost tax collection and foster greater public trust in regional governance. According to Rosdiana and Martani . , tax compliance is shaped by taxpayer awareness, perceptions of the tax system, and the quality of public services. They argue that accountability in public services enhances taxpayer trust in the government, which in turn encourages compliance. In the context of modern taxation, taxes are no longer seen solely as legal obligations but also as a form of civic responsibility that reflects public participation in national economic development. Empirical studies by Rakhmadhani . and Pranata et al. have shown that taxpayer awareness significantly influences compliance. Likewise. Fitriana . and Rachmawati . emphasize the positive contribution of the opsen PKbNKB policy to regional revenue and motor vehicle tax compliance. Research by Wulandari . and Prayitna & Witono . further confirms that accountability in public services positively affects taxpayersAo willingness to meet their obligations. Logically, the higher a taxpayerAos awareness of their rights and responsibilities, the more likely they are to comply. clear, well-communicated opsen policy can foster taxpayer engagement, while accountable and transparent public services help reduce distrust and reinforce fiscal loyalty and compliance METHOD This research adopts a quantitative approach using a survey method, aimed at examining the influence of independent variables on the dependent variable based on data collected from respondents through questionnaires. A quantitative method is employed because the collected data will be statistically analyzed to test the proposed hypotheses. The population in this study consists of all registered motor vehicle taxpayers at the Regional Revenue Management Office of Cirebon Regency I Sumber, totaling 430,079 individuals . 5 dat. The sample size was determined using Slovin's formula with a 10% margin of error, resulting in a sample of 100 2778 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 The sampling technique used is accidental sampling, where respondents are selected based on chance, provided they meet the criteria as active taxpayers. The type of data utilized in this research is primary data, collected directly from respondents through the distribution of questionnaires. The data source comprises motor vehicle taxpayers who engage in transactions or services at the Cirebon Regency PPDPD office in Sumber. The research instrument used is a structured, closed-ended questionnaire developed based on indicators of each research variable. Respondents' answers are measured using a 5-point Likert scale, ranging from 1 (Strongly Disagre. to 5 (Strongly Agre.

The calculated F-value is 18. 071, which is greater than the F-table value of 3. 09, with a significance level of 0. 000 < 0. This confirms that taxpayer awareness, the PKB-BBNKB revenue-sharing scheme, and public service accountability collectively have a significant effect on taxpayer compliance. 2782 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 The coefficient of determination (RA) is 0. 361, meaning that 36. 1% of the variance in taxpayer compliance can be explained by the three independent variables in the model. The 9% is influenced by other variables not examined in this study. The correlation coefficient (R) is 0. 601, indicating a moderately strong and positive relationship. The findings of this study demonstrate that taxpayer awareness (X. plays a pivotal role in increasing motor vehicle taxpayer compliance. This aligns with the Theory of Planned Behavior (Ajzen, 1. , which posits that individual behavior is determined by intention, shaped by attitudes, perceived behavioral control, and subjective norms. In this context, a wellinformed and aware taxpayer is more likely to voluntarily comply with tax obligations. These results are also consistent with the research of Nugroho & Santoso . and Wijayanti . , who found that awareness significantly influences tax compliance. The significant effect of the PKB-BBNKB revenue-sharing policy (X. confirms that a transparent and decentralized tax sharing mechanism can enhance compliance. The implementation of the 66% optional sharing policy . in West Java, as per Regional Regulation No. 9/2023, reflects a shift towards fiscal decentralization that resonates with taxpayers. These findings echo the work of Fitriana . and Rachmawati . , who observed that structured revenue-sharing frameworks improve the perceived fairness and effectiveness of tax systems, thereby boosting However, the public service accountability (X. variable did not have a statistically significant effect on tax compliance. This finding corroborates the studies of Anu . and Fitrianingsih . , which revealed that although public service accountability is important for institutional trust, it may not directly influence compliance behavior unless it is highly visible or accompanied by immediate taxpayer benefits. The lack of impact may also stem from the publicAos limited awareness of performance indicators or dissatisfaction with public service Implications and Future Research Directions The results of this study offer several important implications. First, local governments should prioritize public education programs to further enhance taxpayer awareness, especially targeting populations with low compliance rates. Second, the effectiveness of the PKbNKB revenue-sharing system suggests that policymakers should continue refining and promoting transparent fiscal mechanisms, making sure that taxpayers see tangible benefits from their contributions. Third, although public service accountability did not significantly influence compliance, improving transparency, responsiveness, and service delivery standards remains essential to building public trust. CONCLUSION This study aims to examine the influence of Taxpayer Awareness. PKB-BBNKB Discount (Opse. , and Public Service Accountability on the Compliance of Motor Vehicle Taxpayers at the Regional Revenue Management Center of Cirebon Regency I Sumber. The analysis results show that Taxpayer Awareness has a significant positive effect on taxpayer This indicates that the higher the taxpayer's awareness of their tax obligations, the more compliant they are in fulfilling those obligations. Furthermore, the PKB-BBNKB Discount also contributes positively and significantly, suggesting that the incentives and services provided can encourage taxpayer compliance. Additionally. Public Service Accountability plays an important role in strengthening taxpayer trust and satisfaction, thereby increasing the level of compliance. This study illustrates that these three variables mutually support each other in fostering better compliance within the research area. However, this study has limitations, including the use of a sample limited to only one regional office, which may restrict the generalizability of the results. Moreover, other factors 2783 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 potentially influencing taxpayer compliance, such as sanctions and tax education, were not discussed in this research. Therefore, it is recommended that future studies expand the scope to cover broader regions and include other relevant variables to gain a more comprehensive The Regional Revenue Management Office is also encouraged to enhance socialization programs and services to continuously improve awareness and accountability, thereby optimizing taxpayer compliance.
