Indonesia's core tax administration system will officially launch in January 2025. According to the Director General of Taxes at the Ministry of Finance, the system is expected to gradually increase the tax rate from approximately 10% to 12% over the next five years, aiming to drive better economic growth. Currently, the Directorate General of Taxes is fully promoting socialization and education efforts, having trained over 50,000 large-transaction taxpayers. It has also opened the core tax simulator to other taxpayers, provided related books and video guides on its official website, and conducted system usage training for tax officers to make them community trainers. Through these preliminary efforts, the goal is to ensure smooth coordination among all parties when the system goes live, avoiding gaps in understanding and operation.
