Indonesia’s ambitious digital transformation through the Online Single Submission (OSS) system has reshaped how foreign investors register and manage their businesses.
Designed to streamline licensing and reduce bureaucratic delays, the OSS portal offers a centralised platform for obtaining business permits online. However, despite this modernisation, the requirement for legalised documents remains strict and non-negotiable.
For Australian companies looking to tap into Indonesia’s growing market, understanding the nuances of document legalisation under the OSS system is vital to avoid costly delays and ensure smooth registration.
Indonesia’s Accession to the Hague Apostille Convention: A Game Changer
Indonesia joined the Hague Apostille Convention Abolishing the Requirement of Legalisation for Foreign Public Documents in October 2021, with the treaty entering into force in June 2022. This development marked a significant milestone for Australian businesses.
Thanks to this accession, Australian documents authenticated with a DFAT Apostille are now recognised in Indonesia without the need for further embassy or consular legalisation. This reduces processing time and administrative overhead, streamlining the submission of critical documents required by the OSS system.
Yet, the process is far from entirely digital or automatic. Document legalisation still requires precision, with notarisation and Apostille completed correctly to meet Indonesian regulatory standards.
The OSS System and Its Document Requirements
The OSS system centralises business licensing, allowing companies to apply online for a variety of permits and certifications. Despite the online nature of the system, the government enforces rigorous document verification procedures.
Australian investors typically need to prepare the following legalised documents:
- Company Constitution (Articles of Association)
- Board Resolutions authorising foreign investment or business activities
- Power of Attorney (PoA) for local representatives
- Proof of capital injection or bank guarantees
- Shareholders’ identification and clearances
All these documents must be notarised in Australia and carry a valid DFAT Apostille to be accepted by Indonesian authorities.
Why Legalised Documents Still Matter—Even in a Digital System
The OSS system simplifies licensing, but it does not eliminate the requirement for legalised, authenticated or Apostilled documents. Indonesian regulators use these documents to:
- Validate company identity and formation
- Confirm the authority of foreign representatives
- Verify capital contribution or shareholding structures
- Satisfy KYC and sector-specific compliance checks
Failure to submit properly prepared and Apostilled documents can result in licensing rejection, weeks of delays, or additional embassy-level checks—even with online registration complete.
