Reverse-charge and Overseas Vendor Registration (OVR) — Eligibility and requirements checklist

Reverse-charge and Overseas Vendor Registration are the two mechanisms that bring imported services into Singapore’s GST net. Reverse-charge makes a Singapore recipient account for GST on services bought from overseas suppliers, while OVR requires large overseas vendors to register and charge GST on digital and low-value goods sold to Singapore customers.

Why reverse-charge and Overseas Vendor Registration exist

Before these rules, services and digital products bought from overseas escaped GST while the same supply from a local vendor was taxed, disadvantaging Singapore businesses. The Goods and Services Tax Act 1993, as amended, closed that gap with two complementary regimes. Reverse-charge shifts the accounting obligation onto the local business customer for imported services. OVR puts the obligation on the overseas supplier for business-to-consumer digital services and low-value goods. Together they tax consumption in Singapore regardless of where the supplier sits.

Reverse-charge: who it applies to

Reverse-charge applies to GST-registered businesses that would not be entitled to full input-tax credit — typically partially exempt businesses such as financial institutions, and businesses that make exempt supplies — when they procure services from overseas suppliers. Such a business accounts for output tax on the imported services as if it were the supplier, and claims input tax only to the extent its activities allow. A fully taxable business with full input-tax recovery is generally not caught, because the reverse-charge and the corresponding claim would net to nil. Non-GST-registered businesses can be pulled into registration if their imported services exceed S$1 million and they would not qualify for full input-tax credit.

OVR: who must register

Overseas Vendor Registration applies to overseas suppliers and, in some cases, electronic marketplaces. An overseas supplier must register for GST under the OVR regime if it has global turnover exceeding S$1 million and makes B2C supplies of digital services, non-digital services, or low-value goods to Singapore customers exceeding S$100,000 in a 12-month period. Once registered, the vendor charges 9% GST on those supplies and files returns like a local business, though under a simplified pay-only registration.

Eligibility and requirements checklist

  • Reverse-charge: GST registration plus imported services, where the business is not entitled to full input-tax credit.
  • Reverse-charge registration trigger: imported services over S$1 million for an otherwise non-registered business without full credit entitlement.
  • OVR: overseas supplier with global turnover over S$1 million and Singapore B2C supplies over S$100,000.
  • Systems to identify the customer’s status and location and to apply 9% correctly.
  • Record-keeping to evidence the treatment for five years.

Cost, timeline and compliance effort

There is no registration fee, but the compliance cost is in systems and judgement. A partially exempt business implementing reverse-charge should budget for a review of every overseas services invoice, an apportionment methodology for input tax, and updated return workpapers. Overseas vendors registering under OVR can usually complete the simplified registration within a few weeks and then file GST on a quarterly basis. Both regimes reward automation, because the volume of individual transactions is high.

Common mistakes and gotchas

Common failures include a fully taxable business over-applying reverse-charge where it is not required, a partially exempt business missing it entirely, and misclassifying a supply as goods rather than services. Overseas vendors frequently under-track the S$100,000 Singapore threshold, or fail to distinguish B2B from B2C supplies, which changes who accounts for the tax. Determining the customer’s GST status and belonging is the recurring pain point, and getting it wrong shifts the liability unexpectedly.

Numerical specifics at a glance

GST rate 9%; reverse-charge registration trigger imported services over S$1 million without full input-tax credit; OVR global-turnover threshold S$1 million; OVR Singapore-supply threshold S$100,000; low-value goods threshold S$400 for imported goods brought into OVR; records kept five years; returns generally quarterly.

Determining customer belonging and status

The pivot on which both regimes turn is knowing who the customer is and where it belongs. For imported services, a Singapore GST-registered business customer normally self-accounts under reverse-charge, whereas a consumer is served under OVR by the overseas vendor. Overseas suppliers therefore need a reliable way to establish whether a customer is GST-registered — usually by collecting the GST registration number — and to determine the customer’s belonging by proxies such as billing address, IP address, payment details and country code. Weak evidence here is the single biggest source of mis-charging.

Electronic marketplaces and redeliverers

The rules reach beyond direct suppliers. An electronic marketplace can be treated as the supplier of digital services made through it, making the marketplace responsible for charging and accounting for GST rather than each underlying merchant. Similarly, redeliverers who arrange shipment of low-value goods can be brought into the OVR net. This design concentrates the compliance obligation on the large intermediaries best placed to operate it, but merchants selling through those platforms should confirm who is accounting for the GST to avoid double-charging.

Practical compliance for Singapore recipients

A partially exempt Singapore business should build reverse-charge into month-end: flag every overseas services invoice, compute the output tax at 9%, apply the input-tax apportionment its activities allow, and carry both figures into the Form F5. Keeping a standing schedule of recurring overseas suppliers — software subscriptions, marketing platforms, professional advisers — makes the process repeatable and audit-ready. The same schedule helps management see the true cost of imported services once irrecoverable GST is added.

FAQs

Does reverse-charge affect a fully taxable business? Generally no, because the output tax and input-tax claim offset. It mainly affects partially exempt and exempt businesses.

What is a low-value good under OVR? Imported goods valued at up to S$400 that are shipped to Singapore consumers, brought into GST through the OVR regime.

Who accounts for GST on B2B imported services? The Singapore business customer, through reverse-charge, where it lacks full input-tax entitlement.

How does an overseas vendor register? Through IRAS’s simplified pay-only OVR registration, after which it charges and files 9% GST.

Are the thresholds tested annually? They are tested on a rolling basis over past and prospective 12-month periods.

See IRAS for the reverse-charge and OVR rules and the Ministry of Finance for GST policy where it touches financial reporting.
