Selling online rarely stops at the border. A Singapore company that lists on a regional marketplace, sells subscriptions to overseas users, or buys advertising from a foreign platform sits across several different GST rules, and they do not all point the same way. Getting GST for e-commerce and digital services wrong is expensive, because IRAS assesses the tax you should have charged whether or not you collected it from the customer.
Raffles Corporate Services works with a panel of experienced Singapore law firms who offer cost-effective and efficient legal service and advice. This article is general information only and is not legal advice.
This guide sets out how GST applies to online sales, digital services and imported goods in Singapore, what the Overseas Vendor Registration and reverse charge regimes mean in practice, and where companies most often slip.
Who this applies to
GST for e-commerce and digital services affects a wider group of businesses than most directors expect. You should read on if your company:
- Sells physical goods online, through your own website or a marketplace such as Shopee, Lazada or Amazon
- Supplies digital services: software as a service, apps, e-books, streaming, online courses, cloud storage or digital advertising
- Operates an electronic marketplace that lets third parties sell through it
- Buys services from overseas suppliers such as cloud hosting, design work or software licences
- Imports low-value goods for resale
- Is not yet GST-registered but is approaching S$1 million in taxable turnover
Overseas suppliers with no physical presence here may also be caught. A foreign company that sells enough to Singapore consumers can be required to register even though it has no office or staff in the country.
Key rules and requirements in Singapore
The registration threshold
A business must register for GST if its taxable turnover exceeded S$1 million in the past calendar year, or if it reasonably expects to exceed S$1 million in the next 12 months. The prospective test matters for e-commerce, where one viral product or a new marketplace listing can lift revenue quickly. Voluntary registration is possible below the threshold and is common where a business sells mainly exports and wants to recover input tax. The current rate is 9%.
Where the supply takes place
For goods, GST generally follows the physical movement. Goods sold and delivered within Singapore are standard-rated. Exports can be zero-rated, but only if you hold the required export evidence, and IRAS expects that documentation within 60 days of supply. Without it, the sale reverts to standard-rated and you absorb the tax.
For services, the position turns on where the customer belongs and whether the service qualifies as an international service under section 21(3) of the GST Act. Supplies to a person belonging outside Singapore can often be zero-rated, but the exceptions are narrow and fact-specific.
Overseas Vendor Registration
Since 1 January 2020, overseas suppliers of digital services to Singapore consumers have had to register and charge GST under the Overseas Vendor Registration regime. From 1 January 2023 it was extended to imported low-value goods (S$400 or below, imported by air or post) and to non-digital services supplied remotely to consumers, such as online tutoring.
An overseas supplier must register if it has global turnover above S$1 million and makes more than S$100,000 of business-to-consumer supplies of digital services or low-value goods to Singapore customers in a calendar year. Electronic marketplace operators can be treated as the supplier of everything sold through them, which shifts the burden onto the platform rather than the individual seller.
Reverse charge, invoicing and records
Business-to-business imports work differently. Under the reverse charge regime, a GST-registered business that is not entitled to full input tax credit must account for GST on services bought from overseas suppliers as if it had made the supply itself, then recover input tax to the extent its position allows. A firm with partly exempt income that buys S$180,000 of overseas research and software licences in a year therefore carries a real cost, which should have been priced into its engagements.
Returns are filed through the IRAS myTax Portal, usually quarterly, within one month of the end of each accounting period, and supporting records must be kept for at least five years. IRAS is also phasing in the GST InvoiceNow requirement, under which registered businesses transmit invoice data through the InvoiceNow network, so check where your company sits in that timeline.
Step-by-step process
- Map your revenue streams. Domestic sales, exports, marketplace sales, subscriptions, platform fees. Each may have a different treatment.
- Classify each stream as standard-rated, zero-rated, exempt or out of scope, and record the reasoning, not just the answer.
- Test the threshold on both the retrospective and prospective bases. Diarise a monthly check if you are within 20% of S$1 million.
- Register if required through myTax Portal. Registration is not instant, so allow lead time.
- Configure your systems. Set tax codes correctly in your shopping cart, invoicing tool and accounting software, and capture customer location data at checkout.
- Collect your evidence routinely: export documents, belonging status, settlement reports. Evidence gathered later is rarely as good.
- Account for reverse charge. Identify imported services in your payables ledger each month.
- File and pay on time, reconciling the return to your ledgers before submission rather than after.
Common mistakes to avoid
- Assuming the marketplace has handled it. Some platforms account for GST on your behalf, others do not, and treatment can differ between a platform’s Singapore and regional operations. Read the settlement report.
- Zero-rating exports without proof. An invoice addressed to an overseas customer is not export evidence.
- Treating a billing address as conclusive. Belonging status depends on where the customer has a business or fixed establishment, not simply what was typed at checkout.
- Ignoring reverse charge because it nets to nil. Omitting the entries still misstates the return.
- Charging GST before the effective registration date. Collecting tax you are not yet registered to collect is an offence.
- Letting the shopping cart decide the law. Default tax settings in off-the-shelf platforms are often built for other jurisdictions.
Practical examples
A software company selling subscriptions. A Singapore company sells a project management tool. Singapore subscribers are charged 9% GST. Business subscribers in Malaysia and Australia belong outside Singapore, so those supplies can be zero-rated provided the company documents each customer’s belonging status. It pays a US cloud provider for hosting; as it is fully taxable, reverse charge does not bite, but the position is reviewed annually.
An online retailer using a regional marketplace. A homeware seller lists on a marketplace registered under the Overseas Vendor Registration regime for low-value goods. For stock shipped from its Singapore warehouse to Singapore buyers, the seller accounts for GST itself. For goods under S$400 shipped directly from its overseas supplier through the platform, the platform accounts for it. Two revenue lines, two different answers, one set of accounts that must reflect both.
How a corporate secretary can help
GST is administered by IRAS, but it sits inside a wider compliance picture. Registration status, the effective date of registration and changes in business structure all interact with ACRA filings and the company’s statutory records. When a company restructures, adds a subsidiary or changes its financial year end, the GST consequences are easy to lose in the paperwork.
Raffles Corporate Services supports companies across corporate secretarial work, ACRA filings, accounting, GST and corporate tax compliance, and payroll, so one team keeps the registers in order, prepares the books that feed the GST return, and flags when a new revenue stream has changed the company’s GST position.
Requirements may change, so always check the latest guidance from ACRA, IRAS or MOM, or consult a professional adviser.
Frequently Asked Questions
Do I charge GST to overseas customers buying my digital product?
If the customer belongs outside Singapore and the supply qualifies as an international service, it can be zero-rated. You must be able to show how you determined belonging status, so capture that evidence at the point of sale.
My turnover is below S$1 million. Should I register voluntarily?
It depends on your customer mix. If most sales are zero-rated exports and you incur Singapore input tax, voluntary registration can produce net refunds. If you sell mainly to Singapore consumers, it adds 9% to your prices and more administration. Voluntary registrants must also stay registered for at least two years and meet conditions set by IRAS.
Does the marketplace charge GST or do I?
Where an electronic marketplace operator is treated as the supplier, it accounts for the GST. Where it is not, you do. The answer varies by product and shipment route, so check each platform’s Singapore GST terms and keep the settlement reports.
What happens if I should have registered and did not?
IRAS can backdate the registration and assess the GST you should have charged from that date, with penalties. Because you usually cannot bill past customers, the tax comes out of your margin. Voluntary disclosure generally reduces penalties, so raise it early.
Key takeaways
- GST here turns on what you sell, where the customer belongs and how the goods move, not on where your website is hosted.
- The registration threshold is S$1 million of taxable turnover, tested both retrospectively and prospectively, and the current rate is 9%.
- Overseas Vendor Registration pulls foreign suppliers and marketplaces into the Singapore GST net; reverse charge pulls in local businesses buying services abroad.
- Zero-rating an export is a documentation exercise as much as a legal one, and the evidence has a deadline.
- Marketplace sales are not automatically someone else’s GST problem.
- Keep records for five years, in a form a reviewer could follow without your explanation.
