3E Accounting Indonesia, registered locally as PT 3E Accounting Services, operates from Suite 5001 on the 50th floor of Menara BCA on Jalan M.H. Thamrin in Central Jakarta. It is the Indonesian member of the 3E Accounting International network, a Singapore-founded group of corporate services firms now present in over 100 countries, so the practice is built around serving foreign founders and inbound investors rather than domestic clients only.

The firm's services span the full lifecycle of a foreign-owned business in Indonesia: PT PMA and local PT incorporation, OSS and NIB business licensing, corporate secretarial work, bookkeeping and accounting system setup, consolidated accounts, payroll, and corporate tax compliance. On the personal side, 3E publishes dedicated guidance on Tax Identification Numbers (NPWP) and runs an Individual Personal Income Tax service, which is the practical entry point for expatriates who need to register for an NPWP and file an annual individual return once they cross the 183-day residency threshold.

Everything is delivered in English, with published resource guides on Indonesian taxation, immigration and company law that make the compliance calendar easier to follow for newcomers. The Menara BCA office is by appointment only, open Monday to Friday 9am to 6pm.
