Abstract

This study examines the impact of taxpayer compliance, tax audits, and tax collection on Corporate Income Tax revenue at the Foreign Investment Tax Office One (Indonesia) between 2022 and 2024. Because taxes act as the primary source of national income, maximizing these funds requires robust voluntary compliance from corporate entities alongside the efficient execution of auditing and collection strategies by tax authorities. To evaluate these factors, this study utilizes a quantitative methodological approach, relying on secondary data gathered from official records. A purposive sampling technique was deliberately employed to ensure the relevance of the selected data points. Subsequently, the data was analyzed using multiple linear regression. Despite previous studies identifying compliance and law enforcement as key drivers of tax revenue, empirical evidence regarding their interplay in a post-tax reform context remains fragmented. Addressing this research gap, this study examines the impact of taxpayer compliance, tax audits, and tax collection on Corporate Income Tax revenue at the Foreign Investment Tax Office One (Indonesia) between 2022 and 2024. This specific period was selected to capture the dynamics following the implementation of the Harmonization of Tax Regulations Law (Law Number 7 of 2021). The empirical findings of this study offer compelling evidence regarding the interplay of these variables. Ultimately, the results of the study indicate that taxpayer compliance, tax audits, and tax collection have a positive effect on Corporate Income Tax revenue. The findings underscore the complementary nature of the Ability to Pay Theory and the Public Enforcement of Law Theory in modern tax administration.

Abstract

State revenue is influenced by the contribution of tobacco excise. According to the APBN Kita publication by the Ministry of Finance (2026), Tobacco Excise (CHT) revenue in 2025 reached Rp216.9 trillion. This study was conducted with the aim of determining the effect of cigarette excise, electronic cigarette excise, the gross domestic product of the cigarette and tobacco industry, and the cigarette consumer price index on state revenue.This quantitative study uses 38 time series data points from 2016 to the second quarter of 2025. Data analysis was conducted using multiple linear regression with a natural logarithm transformation and then executed through the RStudio program. The empirical result demonstrates that the model escplains 44.34% (Adjusted R2) of the variance in state revenue research results indicate that the rates of tobacco excise, electronic cigarette excise, and cigarette CPI have a negative and significant effect on state revenue. Meanwhile, the GDP of the tobacco industry does not significantly affect state revenue. This study demonstrates that the government-imposed tariffs have led to a decrease in legal cigarette consumption, which ultimately reduces state revenue.

Abstract

The implementation of the Coretax Administration System represents a major transformation in Indonesia’s tax administration aimed at improving the effectiveness, efficiency, and transparency of tax administration through integrated business processes. This study analyzes Value Added Tax (VAT) calculation and reporting practices in property and real estate companies, examines changes in the input VAT crediting mechanism following the implementation of Coretax, and identifies administrative and technical challenges encountered by taxpayers. Using a descriptive qualitative approach, data were collected through in-depth interviews, observation, and documentation involving tax officers, an accounting and tax manager, a tax consultant, and an Account Representative from the Directorate General of Taxes. The findings indicate that VAT calculation and tax invoice issuance have generally been conducted in accordance with applicable regulations. Coretax has improved VAT administration through data integration, prepopulated data, automatic taxpayer identification, and validation processes that support reporting accuracy and efficiency. However, challenges remain, including transaction data changes, transaction cancellations, invoice discrepancies, data reconciliation requirements, and occasional system disruptions near tax reporting deadlines. The study highlights the importance of internal controls, periodic reconciliation, and continuous system improvement in supporting effective VAT administration within the property and real estate sector.
