Foreign companies looking to establish a presence in Singapore face a structural choice that will shape their tax bill, liability exposure and ongoing compliance burden for years to come: incorporate a subsidiary, or register a branch office. Both are recognised under the Companies Act 1967, both can hire local staff and lease premises, and both can hold bank accounts — but the resemblance ends there.
This guide walks through how each structure works, the legal and tax differences that matter in practice, and how to decide which fits your business plan.
The two structures at a glance
A Singapore subsidiary is a private limited company incorporated in Singapore under the Companies Act. Although it can be wholly owned by a foreign parent, it is a separate legal entity with its own assets, liabilities and tax residency. A branch office, by contrast, is a registered local extension of the foreign parent — legally the same entity, simply registered with the Accounting and Corporate Regulatory Authority (ACRA) to do business in Singapore.
The practical consequence: a subsidiary’s liabilities stop at the company itself. A branch’s liabilities flow straight back to the foreign parent.
Legal status and liability
Under Singapore law, a subsidiary enjoys limited liability — shareholders are liable only to the extent of their unpaid shares. Directors’ duties under the Companies Act apply, but the foreign parent’s assets are insulated from creditor claims against the subsidiary.
A branch office is treated as the foreign parent doing business locally. If a customer or supplier sues the branch, they are suing the parent. For risk-averse groups, particularly those operating in regulated industries or holding valuable IP overseas, this is often the decisive factor.
Tax treatment
The Inland Revenue Authority of Singapore (IRAS) treats the two structures very differently.
Subsidiary
A Singapore-incorporated subsidiary is, by default, tax resident in Singapore if its management and control is exercised here. As a resident company it can claim:
- The start-up tax exemption for its first three Years of Assessment.
- The partial tax exemption that applies to all resident SMEs.
- Singapore’s network of more than 90 double taxation agreements.
- Foreign-sourced income exemptions where conditions are met.
Branch
A branch is treated as non-resident for tax purposes because management and control sits with the foreign parent abroad. It therefore cannot claim the start-up exemption, has limited access to tax treaty benefits, and its Singapore-sourced profits are still taxed at the headline corporate rate of 17%. Branch losses generally cannot be exported to the parent for relief unless the home jurisdiction permits.
Set-up and ACRA filings
A subsidiary is incorporated through ACRA’s BizFile portal — typically within one working day if the documents are clean. Requirements include at least one locally resident director, a company secretary appointed within six months, a registered office address and a minimum of one share.
A branch must register the foreign parent’s certificate of incorporation, constitution and a memorandum appointing at least one Singapore-resident authorised representative to accept service of process. Filing the parent’s audited financial statements with ACRA each year is mandatory — including statements that may contain group financials the parent would rather not put on a public register.
Ongoing compliance
Both structures must file annual returns with ACRA, prepare accounts under the Singapore Financial Reporting Standards, and comply with the Corporate Service Providers Act 2024. The branch’s compliance load is heavier because the parent’s worldwide accounts must be lodged annually — a cost most multinationals would prefer to avoid.
Decision framework
Choose a subsidiary if you want:
- Limited liability and ring-fenced risk.
- Access to start-up and partial tax exemptions.
- Eligibility for Singapore government grants (most require Singapore-incorporated entities).
- A clean, ASEAN-facing platform for future fundraising or M&A.
Choose a branch if you want:
- Quick market entry without a separate board structure.
- To keep Singapore operations on the parent’s consolidated balance sheet.
- To repatriate profits back to the parent without dividend-payment formalities.
In our experience, more than 90% of foreign businesses entering Singapore choose a subsidiary — the limited liability and tax efficiency simply outweigh the marginal speed advantage of a branch.
Conversion is possible — but not free
Companies that start with a branch and later convert to a subsidiary need to transfer assets, contracts and employees into the new entity, deregister the branch, and notify IRAS and CPF. The costs of converting often exceed those of incorporating a subsidiary from the start.
