Every month, thousands of Singapore businesses pay overseas technology companies — Google, Meta (Facebook), Zoom, LinkedIn, Dropbox, Adobe, and countless others — for digital services. Most of these businesses never stop to consider whether GST applies to these payments. In many cases, it does. Under Singapore’s reverse charge mechanism, introduced from 1 January 2020 and extended to all GST-registered businesses from 1 January 2023, Singapore businesses that purchase certain services from overseas suppliers may be required to account for GST on those purchases — even though the overseas supplier does not charge Singapore GST. This guide explains the rules, who they apply to, and what your company needs to do.

What Are “Imported Services”?

Imported services are services that are provided by an overseas supplier to a Singapore recipient, where the supply would be a taxable supply if made by a supplier in Singapore. The most common examples relevant to Singapore SMEs include:

  • Cloud computing and software-as-a-service (SaaS) subscriptions (e.g., Microsoft 365, Google Workspace, Salesforce, Xero, QuickBooks)
  • Online advertising services (e.g., Google Ads, Meta Ads, LinkedIn Ads, TikTok for Business)
  • Video conferencing services (e.g., Zoom, Microsoft Teams)
  • File storage and collaboration tools (e.g., Dropbox, Box, Google Drive)
  • Design and creative platforms (e.g., Adobe Creative Cloud, Canva for Teams)
  • Data and analytics services
  • Legal, consulting, and professional services provided remotely from overseas
  • Financial services and advisory fees paid to overseas firms (where not exempt from GST)

The key question for each payment is: if this service were supplied by a Singapore-based supplier, would it be a standard-rated (9%) taxable supply? If yes, it qualifies as an imported service for GST purposes.

The Two GST Mechanisms for Imported Services

1. The Overseas Vendor Registration (OVR) Regime (B2C)

For supplies of digital services to consumers (private individuals and non-GST-registered businesses), overseas suppliers with global annual revenue exceeding S$1 million and digital services supplied to Singapore customers exceeding S$100,000 must register for GST in Singapore under the Overseas Vendor Registration (OVR) regime. Under this regime, the overseas supplier charges and collects Singapore GST (9%) from their Singapore customers.

This means: if you pay Google or Zoom using a personal card without a business billing profile, the overseas supplier is likely already charging you 9% Singapore GST. But many business customers have set up business billing accounts, which changes how GST applies.

2. The Reverse Charge Mechanism (B2B — Applies to GST-Registered Businesses)

For GST-registered businesses in Singapore purchasing imported services, the reverse charge mechanism applies. Under this mechanism, the Singapore GST-registered business — not the overseas supplier — must account for GST on the imported services it purchases.

The reverse charge mechanism has applied to all GST-registered businesses since 1 January 2023 (it was initially limited to businesses that cannot fully claim input tax). This means that every Singapore company that is registered for GST and purchases imported services from overseas must self-account for GST on those purchases through its regular GST returns.

Does the Reverse Charge Apply to Your Business?

If your Singapore company is GST-registered and pays any overseas supplier for services that would be taxable if supplied locally, the reverse charge mechanism applies. Ask yourself these questions for each overseas service payment:

  1. Is my company GST-registered?
  2. Is the supplier overseas (i.e., not a Singapore-registered business charging Singapore GST)?
  3. Does the service relate to my business activities in Singapore?
  4. Would this service be a standard-rated supply if made by a Singapore GST-registered supplier?

If you answer yes to all four questions, the reverse charge applies. You must account for GST at 9% on the value of the imported service in your GST return.

How to Account for GST Under the Reverse Charge

Accounting for the reverse charge in your GST return involves the following steps:

  1. Identify all imported services: Review your company’s payments to overseas suppliers and identify which payments are for services subject to reverse charge.
  2. Calculate the GST: Apply the current GST rate (9% from 1 January 2024) to the value of the imported service (excluding any Singapore GST already charged by the overseas supplier under OVR).
  3. Report in Box 6 of your GST return: The value of imported services subject to reverse charge is reported in Box 6 (Output Tax Due) of your GST F5 return.
  4. Claim input tax in Box 7 (if fully taxable): If your business is fully taxable (i.e., all or substantially all your supplies are standard-rated), you can claim the reverse charge GST as input tax in Box 7 of the same GST return. The net GST payable from reverse charge would then be nil.
  5. Partial exemption businesses: If your business makes both taxable and exempt supplies, you may not be able to claim the full reverse charge GST as input tax. You must apply your partial exemption formula to determine the claimable portion.

Full guidance on GST return filing is available from IRAS. Businesses that are unsure whether they are correctly accounting for reverse charge should review their GST filing with their accountant.

Which Overseas Services Are Exempt from Reverse Charge?

Not all imported services are subject to reverse charge. The main categories that are exempt include:

  • Zero-rated services: Services that would be zero-rated if supplied in Singapore (e.g., certain international services, services directly in connection with goods or property outside Singapore)
  • Exempt financial services: Services that would be exempt from GST if supplied in Singapore (e.g., core banking, insurance, fund management) are not subject to reverse charge
  • Services outside the scope of GST: Services that are not treated as a supply in Singapore (e.g., certain employment benefits provided to staff overseas)

Watch Out: Non-GST-Registered Businesses Are Not Exempt

It is a common misconception that only GST-registered businesses need to worry about imported services. The reverse charge mechanism applies specifically to GST-registered businesses. However, non-GST-registered businesses that purchase imported services may find that the overseas supplier charges them Singapore GST directly under the OVR regime — which the non-GST-registered business cannot claim back as input tax.

For companies approaching the GST registration threshold (S$1 million in taxable annual turnover), purchasing imported services before registration means bearing irrecoverable GST cost. After registration, those costs become claimable (subject to reverse charge accounting). This is one reason why voluntary GST registration can be financially beneficial for companies with significant overseas service expenses.

Practical Action List for Singapore GST-Registered Businesses

  • ☑ Run a review of all overseas service payments made in the current GST accounting period
  • ☑ Identify which payments are for services that would be standard-rated if supplied locally
  • ☑ Check whether the overseas supplier has already charged Singapore GST (under OVR) on the invoice — if so, no additional reverse charge is required for that payment
  • ☑ Calculate the reverse charge GST (9% x value of imported services not already GST-charged)
  • ☑ Report the reverse charge amount in Box 6 of your next GST F5 return
  • ☑ Claim the input tax in Box 7 if your business is fully taxable
  • ☑ If your business has partial exemption, apply your partial exemption formula
  • ☑ Keep a schedule of imported services for each GST period as supporting documentation for IRAS

IRAS Audit Risk: Getting Reverse Charge Wrong

IRAS views the reverse charge mechanism as a self-assessed compliance obligation — similar to an honour system. Businesses that fail to account for reverse charge on imported services risk assessments, penalties, and interest on underpaid GST. During a GST audit, IRAS routinely checks whether a business has correctly identified and accounted for all imported services in its GST returns.

Common errors that IRAS auditors look for include: overseas software subscriptions not subject to reverse charge; overseas consulting or advisory fees omitted from GST returns; and misclassifying OVR-charged services as reverse charge (resulting in double GST accounting). Keeping a clear schedule of all overseas service payments and how each was treated is the best protection against audit adjustments.

If you need legal advice on a GST dispute with IRAS, it is advisable to seek professional guidance before responding to any IRAS correspondence.

Beyond GST compliance, sound financial management and planning remain important for Singapore SMEs looking to manage costs and grow sustainably.

Conclusion

The reverse charge mechanism for imported services has been in effect for all GST-registered Singapore businesses since 1 January 2023. If your company pays overseas suppliers for digital tools, software, advertising, consulting, or any other services that would be taxable if supplied locally, you are required to self-account for GST on those payments in your GST returns. With IRAS audits becoming more sophisticated in their detection of reverse charge gaps, the time to ensure your GST returns are correct is now — not after a notice arrives.
