If you work and live in Indonesia, you are required to file your personal income tax through Coretax under the supervision of the Directorate General of Taxes. The process is fully digital, structured, and strictly regulated.<\/p>\n
If you qualify as a tax resident, Indonesia applies residency-based taxation. This means your annual tax return may include worldwide income, not only salary earned locally. Even when your employer withholds monthly tax, the annual filing obligation remains mandatory.<\/p>\n
