rnrnThe Director General of Taxes at the Indonesian Ministry of Finance recently confirmed that, starting July 2026, all tax administrative tasks in Indonesia will be fully handled through the Coretax digital system, which will officially become the sole core platform for Indonesia’s tax system. All tax processes, including tax supervision, enforcement and collection, tax objections, and appeals, will be gradually unified and migrated to the Coretax online platform, marking a comprehensive digital transformation of Indonesia’s tax system. During the 2026 Indonesian Tax Dialogue Forum, officials stated that this upgrade represents a transformative leap for the country’s tax system. The era of traditional paper-based and fixed office systems has completely ended. Now, tax officials can use various devices such as laptops, tablets, and mobile phones to handle tax work anytime, anywhere, greatly enhancing work flexibility. Officials admitted that this digital system should have been implemented 20 years ago, and its full deployment now closes a long-standing gap in Indonesia’s tax digitization.rnrnThe greatest core advantage of the Coretax system lies in enabling interconnected tax data within the Ministry of Finance. By leveraging device interoperability and data integration capabilities, it breaks down previous data silos, making tax supervision more precise and efficient, and significantly enhancing the professionalism and comprehensiveness of tax audits and revenue source monitoring. Since its gradual rollout in 2025, the system has consistently delivered significant positive results for Indonesia’s tax administration and national revenue.As of the latest tax data in July 2026, the results of Indonesia’s tax digital reform are impressive. During the same period, the number of tax invoices increased by 4.62% year-on-year, unified income tax withholding certificates surged by 110.72%, and Article 21 income tax withholding certificates grew by 17.79% year-on-year.rnrnRevenue growth is even more pronounced, with net personal income tax revenue soaring by 272.26% to 8.78 trillion rupiah, and gross corporate income tax revenue increasing by 56.8% year-on-year to 25.11 trillion rupiah. In addition, the Coretax system efficiently supported national tax filing, successfully processing 13.6 million annual tax returns, with an average daily filing volume of 82,000 returns. The tax authority stated that it will continue optimizing system functions, proactively identify and fix operational issues, and further simplify procedures and strengthen legal compliance, making Indonesia’s digital tax system more standardized, convenient, and transparent.
