Purpose and limits of the fifth edition
The fifth edition dated 30 January 2026 determines where service suppliers and customers belong for GST. Supplier status affects whether services are supplied in Singapore; customer status affects relevant international-service zero-rating. These rules are not income-tax residence or treaty permanent-establishment rules and must not be used to interpret treaties. Imported services and low-value goods can separately fall under reverse charge or overseas vendor registration even where the supplier belongs abroad.
The establishment decision sequence
A business establishment (BE) or fixed establishment (FE) requires a physical place with some permanence, including an office or home office, shop, factory, warehouse or workshop. Ownership or a lease is not essential: a customer’s premises made available during service delivery may qualify. Having premises alone is insufficient. With only Singapore establishments, the person belongs here; with only overseas establishments, abroad; with both, examine the relevant supply or receipt; without either anywhere, use usual residence.
Main seat of economic activity
A BE includes the main seat of economic activity, a branch or a qualifying agency. The main seat is where essential general-management decisions and central administration occur, with only one at a time. Consider management decisions, board meetings, senior executives’ work and registered address; essential decision-making takes priority if the indicators conflict. A Bermuda-incorporated investment company without local staff, whose board permanently makes all material decisions in Singapore, has a Singapore BE in the example.
Agency and whole-business outsourcing
Agency may arise expressly or through conduct. Merely hiring a Singapore provider does not automatically give an overseas principal a BE. Where the principal has no own human and technical resources and wholly relies on the provider to carry out its business, the provider can be the agency; the guide points to fund-management-specific rules in the relevant industry guide. In other cases, the provider must be a dependent agency through which the principal actually carries on business.
Comprehensive-control indicators
Dependence can arise from detailed control, such as required approval of management appointments or major contracts, exclusive dealing, no pricing discretion, prescribed operating procedures or activities wholly or almost wholly for one principal over time. Independence is indicated by freedom in methods, reliance on specialist skill and multiple principals. Shareholder control alone, limits to authorised activity scope and routine information exchange do not establish dependence. Each arrangement is assessed as a whole.
Contrasting control examples
A Singapore law subsidiary independently applying its local expertise is not comprehensively controlled merely because a foreign parent subcontracted advice. A training subsidiary restricted to prescribed certified content and methods is controlled. A pilot-training company that must follow a syllabus but can choose simulated scenarios and independently pass or fail trainees is not treated as comprehensively controlled. The distinction concerns substantive operational discretion, not labels or group ownership.
Entrepreneurial risk and carrying on the principal’s business
Dependence also arises where the agent bears no entrepreneurial risk, relies on principal financing and bears no customer-contract economic risk. A logistics company with its own assets, staff and S$4 million other business compared with S$1 million from the principal bears risk; an exclusive R&D company fully financed by a fee percentage does not. Comprehensive control and/or no risk establish dependence, but a BE additionally requires carrying on a main business and making supplies to the principal’s customers. Marketing only or services solely to the parent do not satisfy that further test.
FE resources and service-specific capability
An FE, other than a BE, has the human and technical resources needed for the particular service permanently. Human resources mean the company’s employees, excluding contractors’ or related companies’ employees. Technical resources are generally presumed with employees capable of performing the service. Managing ship construction with employees can create an FE, while attending its launch does not. A server or gaming machine without staff is insufficient. For customers, resources must enable receipt rather than provision of the particular service.
More than 183 days or recurring presence
Continuity normally exists if resources are present more than 183 days in any moving twelve-month period or recur regularly. Count physical presence, including non-working days, collectively per project or particular service, across locations, but count overlapping employee days only once. Count only from service commencement to cessation, excluding unrelated holiday presence before or afterward. The engineering example combines overlapping staff at three plants into 273 days, exceeding the threshold.
Initial projections and unexpected overruns
Assess the expected presence for the whole supply at commencement. An expected breach creates an FE even if actual days fall below the threshold. An initially expected non-breach followed by excess days can still create one unless the Comptroller accepts that excess could not reasonably have been anticipated. Contracts, project plans and deviation reasons support the original projection. If not satisfied, the guide states FE status and resulting registration implications arise from the breach point; the analysis cannot rely solely on a revised end-of-project count.
Supplier: establishment most directly concerned
With local and overseas establishments, identify who actually performs the service. Joint delivery requires assessing tasks and significance to the core service. For a Malaysian exhibition, Singapore budgeting, selection, supplier coordination and event management outweigh the Malaysian office’s administrative support. Only if that assessment is inconclusive should suitable revenue, cost or time proxies be used; Singapore performing more than 50% under the chosen proxy generally makes it most directly concerned. Select the proxy according to service nature and resources.
Identify contracting person and direct beneficiaries
Relevant section 21(3) zero-rating rules can require an overseas contractual person and direct beneficiaries abroad or, for the specified post-1 January 2020 provisions, GST-registered local beneficiaries. These may be different persons. Establish each identity and establishment separately; an overseas invoice address does not answer who directly benefits. Fund-management, digitised-goods and imported remote-service guides can contain their own specific administrative rules.
Customer FE and evidence of local operations
A dormant Singapore office with one employee may receive local tax advice despite lacking resources to supply consultancy. Singapore agents attending training from a local office, or a beneficiary’s Singapore office issuing trading instructions, indicate local establishments. Reasonable checks include direct verification, written declarations, ACRA records and addresses on letterheads, websites, email templates, directories and contracts. Questionable declarations require more verification; the guide says standard-rate in doubt unless overseas belonging is proved.
Customer: where benefits are used
A sole local-benefiting establishment makes the customer local for that service; a sole overseas one makes it overseas. If local and foreign establishments jointly benefit, both are direct beneficiaries for zero-rating tests, rather than simply selecting a majority. Start with contracts and then invoices or correspondence. Indicators include where leased equipment is used, which establishment’s transaction is advised and where research or other deliverables are sent.
Usual residence without establishments
A corporate body without BE or FE belongs at incorporation or legal constitution. An individual has one usual residence during the service, characterised by voluntary settled purpose and continuity in habitual life; a Singapore residential address may establish it. For overseas study or work with multiple addresses, the guide requires continuous absence of at least one year, a fixed overseas home and work not incidental to Singapore business or employment. Temporary reasonable visits do not break absence, but a local employer’s overseas assignment does not satisfy the stated non-incidental condition.
FAQs and appendix decision diagrams
GST group representation alone and a section 33(1) GST-compliance agent alone do not create a foreign company’s local BE or FE. Neither does a registered office automatically create an FE without capability. A cost-plus company servicing only the parent does not conduct the parent’s customer-facing business. Appendix 1 maps supplier establishment and residence tests; Appendix 2 maps recipient tests and relevant zero-rating, including qualifying local registered beneficiaries from 2020. Income-tax residency remains a separate concept throughout both diagrams.
