GST on E-Commerce Sales: What Online Sellers Must Know

Goods and Services Tax (GST) is Singapore’s broad-based consumption tax, currently set at 9% in 2026. For online sellers, this means every taxable supply of goods or digital services made to customers in Singapore may be subject to GST if your business registration is triggered. The Inland Revenue Authority of Singapore (IRAS) requires businesses with annual taxable turnover exceeding S$1 million (over four consecutive quarters) to register for GST. Even if your business is based overseas, rules introduced from 2023 onwards may still pull you into the net.

When GST Registration Becomes Mandatory

Retrospective (backward-looking) liability applies: once your 12-month turnover crosses S$1 million, you must register within 30 days. The liability date is the end of that quarter, and you must charge GST from the day you are registered. IRAS also monitors a prospective view—if at any time you expect turnover to exceed S$1 million in the next 12 months, registration is required immediately.

The S$1 million threshold includes all taxable supplies: sales on Shopee, Lazada, your own website, or offline channels. Zero-rated supplies (like international services) and exempt supplies (financial services) are excluded from the turnover calculation.

Overseas Vendor Registration: The Rules for Non-Singapore Sellers

Since 1 January 2020, non-resident businesses selling digital services to Singapore customers (e.g. software downloads, e-books, streaming) must register under the Overseas Vendor Registration (OVR) regime if their global revenue exceeds S$1 million and B2C sales to Singapore exceed S$100,000 in a 12-month period. This was extended on 1 January 2023 to include remote services (such as B2B services where the customer does not account for GST) and low-value goods.

What’s new in 2026: the OVR now covers non-digital, low-value goods (up to S$400 import value) sold by overseas vendors to Singapore consumers. If you are a foreign e‑commerce seller shipping directly to SG buyers and you cross both the global S$1 million and local S$100,000 thresholds, you must register and charge 9% GST at the point of sale.

Low-Value Goods: GST Now Applies

From 1 January 2023, low-value goods (goods with an import value ≤S$400) supplied via air or post by registered overseas vendors are subject to 9% GST. Previously, such imports were GST-exempt. For online marketplaces like Amazon or Etsy, the platform may be deemed the supplier and required to collect and remit GST if it facilitates the sale and delivery. As a seller, you might continue to list items above S$400 without OVR obligations, but consult the latest IRAS e-Tax Guide on “GST on Low-Value Goods” for precise scoping.

Charging GST on Digital Services

If you sell digital services—website hosting, SaaS subscriptions, online gaming, or digital content—you must determine whether the customer belongs in Singapore. IRAS uses a location-of-enjoyment test based on payment address, IP address, and other proxies. Once registered under OVR, you must issue tax invoices with the 9% GST clearly stated, file quarterly returns, and keep transaction records for at least 5 years.

For B2B supplies of digital services, the business customer might need to reverse‑charge the GST instead. The overseas vendor must still assess whether the customer is a GST-registered business or an end consumer.

Exemptions and Zero-Rating

Certain supplies remain outside the scope. Zero-rated supplies—primarily exports of goods and international services—are taxable at 0% GST, meaning you can claim input tax credits. This is critical if you ship goods from Singapore to overseas buyers: you charge 0% but can recover the GST on your local costs. Exempt supplies (financial services, residential property sales) do not allow input tax recovery and do not count toward the registration threshold. Online sellers of physical products that are shipped internationally should maintain robust export documentation to support zero-rating.

Compliance Steps for Online Sellers

  1. Monitor turnover every quarter using accounting software or platform dashboards.
  2. Register through myTax Portal within 30 days of hitting the threshold.
  3. Issue tax invoices with GST registration number and 9% tax breakdown.
  4. File GST returns (F5 or F8 for quarterly filers) electronically, reporting output tax and claiming input tax.
  5. Keep records for 5 years: invoices, receipts, import permits, export declarations.

Non-compliance triggers penalties from IRAS, including late registration fines up to S$10,000 and a 5% late‑payment penalty on unpaid tax.

FAQ

Q: I sell only through Shopee/Lazada. Do I need to register separately?
A: If the platform acts as an electronic marketplace operator that is GST-registered under the OVR regime, it may account for the GST on your behalf for low-value goods. You must confirm this arrangement and still monitor your own standalone sales. For goods stored in a Singapore warehouse and sold locally, your own turnover counts toward the S$1 million threshold.

Q: What if my turnover drops below S$1 million after registration?
A: You can apply for cancellation of registration if expected turnover over the next 12 months will fall below S$1 million and you have been registered for at least 2 years.
