Abstract

Blockchain technology may provide a solution for the tax industry. It is a distributed ledger that makes it possible to trade anything of value securely, openly, and with less threat of fraud. People might find it simpler to pay their taxes, and governments might find it easier to close the tax gap. But getting from theory to practice is a long journey that also presents challenges, which needed to be discussed. This paper reviewed previous research specifically on the adaptation of blockchain to Value-Added System (VAT). Apart from the theoretical framework and proposed prototype, the majority of research used a qualitative approach, according to the findings. The decentralized network was mostly used as the blockchain structure and design for VAT, with a private block. The consensus that’s mainly used among the articles is PoA, PoA, and PBFT.

Abstract

Corporate Income Tax Payable is the tax levied on a business entity’s taxable income under applicable tax regulations. This study examines the partial and simultaneous effects of Profit, Interest Expense, Operating Expenses, and Current Assets on Corporate Income Tax Payable for state-owned enterprises listed on the Indonesia Stock Exchange from 2019 to 2023. A quantitative approach was used with SPSS version 25. Samples were selected using purposive sampling according to predetermined criteria, yielding ten companies. Data were analyzed using multiple linear regression, classical assumption tests, t-tests, an F-test, and the coefficient of determination. Results from the partial hypothesis tests indicate that Profit has a positive and significant effect on Corporate Income Tax Payable; Interest Expense has a negative and significant effect; Operating Expenses have a positive and significant effect; while Current Assets show no significant effect. The F-test demonstrates that the four variables jointly influence Corporate Income Tax Payable. The model’s R² is 0.967, meaning 96.7% of the variation in Corporate Income Tax Payable is explained by the independent variables. The Adjusted R² of 0.964, which adjusts for the number of predictors, is similar, indicating model robustness. In conclusion, Profit, Interest Expense, and Operating Expenses are important determinants of Corporate Income Tax Payable among the sampled SOEs, while Current Assets are not. Recommendations include enhancing financial transparency, reviewing interest policies, and optimizing operational cost management to improve tax efficiency and strengthen fiscal compliance among SOEs moving forward and governance

Abstract

This study aims to analyze the effectiveness of restaurant tax contributions as a fiscal instrument toward the Regional Original Revenue (PAD) of Medan City during the period of 2020–2024. This research employs a descriptive qualitative approach, utilizing secondary data from the Regional Revenue Agency (Bapenda) of Medan City and primary data obtained through in-depth interviews and field observations. Data analysis was conducted using the NVivo 15 Plus software to map the interrelationships between fiscal policies, restaurant business actors, and taxpayer compliance levels. The results indicate that the contribution of restaurant taxes to Medan City’s PAD averages around 4% per year, with the level of collection effectiveness fluctuating annually. The main challenges identified include low taxpayer awareness, limited field supervision, and technical issues in the online reporting system (e-SPTPD). On the other hand, the local government’s efforts through tax collection intensification programs, taxpayer education and socialization, as well as the implementation of digital reporting systems, have proven effective in improving reporting accuracy and transparency.This study emphasizes that the success of restaurant taxes as a source of regional revenue depends not only on fiscal policy and technology, but also on taxpayer compliance, tax literacy, and collaboration between local governments and business actors. These findings are expected to serve as valuable input for the Medan City Government in formulating more adaptive, effective, and sustainable regional tax strategies.

Abstract

Compliance of individual taxpayers refers to their attitudes and behaviors in carrying out tax obligations in accordance with prevailing laws and regulations. This study aims to analyze the influence of E-Filing, E-Billing, taxpayer awareness, and tax sanctions on the compliance of individual taxpayers at the Pratama Tax Office (KPP) Medan Belawan. The population in this research includes all individual taxpayers registered at KPP Pratama Medan Belawan, totaling 214,866 taxpayers, with a research sample of 100 respondents. The study applies a quantitative approach, where each variable is measured using a Likert scale. Primary data were obtained through the distribution of questionnaires and analyzed using several statistical tests, including data quality tests (validity and reliability), classical assumption tests, multiple linear regression analysis, t-tests, F-tests, and the coefficient of determination (Adjusted R²). The findings indicate that E-Filing and E-Billing do not have a significant influence on individual taxpayer compliance, whereas taxpayer awareness and tax sanctions have a positive and significant impact. Collectively, these four variables show a significant effect on the compliance of individual taxpayers at KPP Pratama Medan Belawan.

The population of this study consists of  companies in the property sector listed on the Indonesia Stock Exchange during 2019-2023. The sampling technique applied was purposive sampling, resulting in 20 companies selected. The data used are secondary data obtained from the companies’ annual financial statements. Data analysis was conducted using multiple linear regression analysis. Prior to hypothesis testing, classical assumption tests were performed to ensure the validity of the regression model. Hypothesis testing was carried out using t-tests to examine the partial effects of each independent variable, F-tests to assess the simultaneous effects, and the coefficient of determination to measure the model’s explanatory power. All analyses were processed using SPSS version 25. The results indicate that the Capital Intensity Ratio has a negative effect on the Effective Tax Rate, the Debt to Asset Ratio also has a negative effect on the Effective Tax Rate, while Tax Loss Carryforward has a positive effect on the Effective Tax Rate. Simultaneously, the results show that the Capital Intensity Ratio, Debt to Asset Ratio, and Tax Loss Carryforward have a significant effect on the Effective Tax Rate.

Abstract

Tujuan penelitian ini untuk menganalisis efektivitas penerapan sistem informasi penjualan pada PT. Expravet Nasuba Medan dengan meninjau sejauh mana sistem tersebut mampu mendukung proses operasional perusahaan, mengidentifikasi faktor penyebab ketidakefektifan, serta merumuskan solusi yang dapat diterapkan untuk meningkatkan kinerjanya. Penelitian ini menggunakan pendekatan kualitatif deskriptif melalui wawancara, observasi, dan dokumentasi yang dilakukan terhadap admin penjualan, admin pembelian, serta sales perusahaan sebagai pihak yang terlibat langsung dalam penggunaan sistem. Hasil penelitian menunjukkan bahwa penerapan sistem informasi penjualan telah membantu perusahaan dalam mempercepat proses pencatatan transaksi, penyusunan laporan penjualan, serta mempermudah pemantauan aktivitas penjualan harian. Namun, efektivitasnya belum sepenuhnya optimal karena masih ditemukan berbagai kendala operasional, seperti kesalahan input faktur, ketidaktelitian dalam pencatatan nama toko dan surat jalan, keterbatasan pemahaman sebagian karyawan terhadap penggunaan aplikasi Asoft, serta belum adanya SOP tertulis yang menjadi pedoman kerja baku sehingga proses masih bergantung pada instruksi lisan.  Sebagai upaya perbaikan, perusahaan mulai menyusun SOP secara tertulis agar alur kerja lebih jelas dan terstandarisasi, melaksanakan pelatihan rutin untuk meningkatkan kompetensi karyawan dalam mengoperasikan sistem, memperketat proses validasi data sebelum disimpan, serta meningkatkan pengawasan agar risiko kesalahan dapat diminimalisir. Dengan langkah-langkah tersebut, diharapkan sistem informasi penjualan dapat berfungsi lebih efektif, akurat, dan reliabel dalam mendukung proses pengambilan keputusan perusahaan.
