Accepted: 2025-05-26 Introduction Melando and Suyono . explained that low compliance in paying motor vehicle tax is the main factor in the failure to achieve optimal tax revenue in Indonesia. Therefore, the government continues to encourage taxpayers to fulfill their obligations and exercise their tax Fulfillment of these obligations is expected to increase tax revenues to support the public Taxpayers' understanding of tax laws also plays an important role. Taxpayers who understand the regulations tend to comply with the provisions to avoid the risk of sanctions, both administrative . uch as fines or higher tax rate. and criminal. Mardiasmo . explains that the definition of tax fines is a financial sanction due to violations of tax provisions or noncompliance with agreements that have been set One of the government's efforts to facilitate the provision of information and payment of motor vehicle tax, especially in Central Java Province, is by creating an online motor vehicle tax payment application . -samsa.

Bapenda Prov Jateng . defines Sakpole as an android-based application to facilitate payment of motor vehicle tax in Central Java. The purpose of the SAKPOLE application system is as a modernization step to provide good and easy service quality to taxpayers. According to Susmita and Supadmi . The cause of the low level of taxpayer compliance is the quality of tax authorities' services that have not reached an optimal level. Tax authorities' services are defined as the fulfillment of community needs through service procedures regulated in organizational policies (Siregar et al. , 2. Good service from the tax authorities is considered crucial because it can increase taxpayer satisfaction, which in turn encourages compliance. The purpose of this study was to determine the effect of tax fines, the implementation of the sakpole system, and the quality of tax services on the compliance of motor vehicle taxpayers at the Sukoharjo Samsat Office. Based on the research objectives above, the hypothesis in this study is: H1: Tax fines, implementation of the sakpole system, and quality of tax services have a significant effect on motor vehicle taxpayer compliance at the Sukoharjo Samsat Office. H2: Tax fines have a significant effect on motor vehicle taxpayer compliance at the Sukoharjo Samsat Office. H3: The implementation of the Sakpole System has a significant effect on motor vehicle taxpayer compliance at the Sukoharjo Samsat Office. H4: Tax Service has a significant effect on Taxpayer Compliance in paying motor vehicle tax at the Sukoharjo Samsat Office. Research Method This study took a population of 26,891 motor vehicle taxpayers registered at Samsat Sukoharjo according to the records of the Central Statistics Agency (BPS) of Sukoharjo City as of June 30, 2020. The research sample was determined through accidental sampling technique with a total of 100 taxpayer respondents. The data collection method combines primary and secondary data, where primary data is obtained through the distribution of questionnaires containing a list of written questions/statements filled out directly by respondents. While secondary data comes from documents of related agencies. The dependent variable in this study is Taxpayer Compliance (Y) and the independent variables used in this study are Tax Fines (X. Implementation of the Sakpole System (X. , and Quality of Tax Service (X. This study uses a quantitative approach. The data analysis methods used in this study are: Descriptive Statistical Analysis Sugiyono . explains that the definition of descriptive statistical analysis is statistics used to analyze data by describing or depicting the collected data as it is without any intention of drawing conclusions that apply to the public or generalizations. Instrument Test Instrument testing is carried out to test the measuring instrument used whether it is valid and reliable ( Sugiyono, 2.

A positive sign means that it shows a unidirectional influence between the independent variable and the dependent variable. The regression coefficient value for the variable Implementation of the Sakpole System (X. has a positive value of 0. This shows that if the implementation of the sakpole system increases by 1%, taxpayer compliance will increase by 0. 203 assuming other independent variables are considered constant. A positive sign means that it shows a unidirectional influence between the independent variable and the dependent variable. The regression coefficient value for the variable of Tax Service Quality (X. has a positive value of 0. This shows that if the quality of tax service increases by 1%, taxpayer compliance will increase by 0. 387 assuming other independent variables are considered constant.

The results of their study prove that the quality of tax services, tax sanctions . , and the implementation of e-Samsat (Sakpol. have a significant influence on taxpayer compliance. However, this is in contrast to the research results of Dita Putri Ramadhanti . regarding the influence of the quality of tax office services, taxpayer income levels, tax sanctions and the implementation of e-Samsat on taxpayer compliance in paying motor vehicle tax, which shows that the quality of tax services , tax sanctions . , and the implementation of e-Samsat do not affect taxpayer compliance. The Influence of Tax Fines on Motor Vehicle Taxpayer Compliance at the Sukoharjo City Samsat Office Based on the t-statistic test, it shows that partially there is a positive and significant influence between Tax Fines (X. and taxpayer compliance (Y) with a regression coefficient value of 2. 230 and a significance value of 0. 022 < 0. Based on the results of the t-test above, it can be concluded that the higher the Tax Fine, the greater the awareness of taxpayers, which will have an impact on increasing the compliance of motor vehicle taxpayers at the Sukoharjo City Samsat Office in paying taxes. The results of this study are supported by the results of Sholikah's . research on the effect of the implementation of e-Samsat, tax sanctions and the quality of tax officer services on taxpayer compliance which shows that tax fines have a positive and significant effect on tax compliance. However, the results of this study contradict the research conducted by Faizatul Azizah . and Tuti Hafiah . on the effect of taxpayer awareness, tax understanding, tax authoritiesAo services, tax sanctions, and the implementation of an online tax administration system on taxpayer compliance which states that tax fines/sanctions do not affect taxpayer compliance. Tax fines serve as a dual-purpose instrument, namely as a form of punishment and an educational effort for taxpayers who are proven to have violated tax provisions. The existence of this fine can create a deterrent effect as well as influence taxpayer awareness in carrying out their tax obligations. The existence of these financial consequences encourages taxpayers to be more careful and conduct thorough evaluations before taking actions that conflict with applicable tax regulations. The Impact of the Implementation of the Sakpole Application System on Motor Vehicle Taxpayer Compliance at the Sukoharjo City Samsat Office The test results using the t-statistic test show that partially there is a positive and significant influence between the Implementation of the Sakpole Application System (X. on taxpayer compliance (Y) with a regression coefficient value of 2. 576 and a significance value of 0. 012 <0. From the results above, it can be concluded that the higher the level of Implementation of the Sakpole Application System given, the greater the effect on increasing compliance of motor vehicle taxpayers at the Sukoharjo City Samsat Office in paying taxes.

The existence of electronic payment features on Sakpole also encourages increased taxpayer compliance, because the more practical and faster process motivates users to complete payments on time. The Influence of Tax Service Quality on Motor Vehicle Taxpayer Compliance at the Sukoharjo City Samsat Office Based on the t-statistic test, it is known that there is a positive and significant influence between the Quality of Tax Service (X. on taxpayer compliance (Y) with a regression coefficient value of 4. 788 and a significance value of 0. 000 <0.
