Reverse-charge and Overseas Vendor Registration (OVR): Frequently asked questions

Reverse-charge and Overseas Vendor Registration (OVR) are the two mechanisms Singapore uses to tax imported services and low-value goods under GST: reverse-charge applies to GST-registered businesses that cannot fully recover input tax, while OVR requires qualifying overseas suppliers themselves to register and charge GST on business-to-consumer supplies into Singapore.

What reverse-charge and Overseas Vendor Registration actually are

Before 2020, imported digital services largely escaped GST because the supplier had no local presence and the Goods and Services Tax Act 1993 taxed supplies made in Singapore, not services consumed here by private individuals. Two regimes closed this gap. Reverse-charge, which took effect from 1 January 2020, requires a GST-registered business in Singapore that is not entitled to full input tax recovery (typically because it makes exempt supplies, such as financial services or residential property) to account for GST on imported services and imported low-value goods as if it were the supplier, then separately claim input tax subject to its normal recovery rate. Overseas Vendor Registration, also from 1 January 2020 and expanded in scope from 1 January 2023, requires overseas suppliers of digital services, and now also non-digital remote services and low-value goods sold business-to-consumer, to register for GST in Singapore if they meet the registration thresholds, and to charge and remit GST directly on those supplies.

The dividing line between the two regimes is the nature of the customer: reverse-charge targets business-to-business imports where the local business itself must self-account for GST, while OVR targets business-to-consumer supplies where the overseas vendor charges GST at the point of sale, much like a locally registered business would.

Who this applies to

Reverse-charge applies to GST-registered businesses in Singapore with a partial exemption or non-full input tax recovery position, most commonly banks, insurers, and residential property developers or landlords, once their imported services and low-value goods exceed the prescribed thresholds. Fully taxable businesses that can claim 100 percent input tax generally fall outside reverse-charge because the self-charged output tax and reclaimed input tax net to nil, so IRAS does not require them to account for it. OVR applies on the supplier side: overseas businesses and electronic marketplace operators selling remote services or low-value goods to non-GST-registered customers (typically consumers) in Singapore must assess their own registration liability against Singapore-specific thresholds, separate from any GST registration they hold in their home jurisdiction.

Eligibility and requirements: numbers that matter

• Reverse-charge threshold: a business must account for reverse-charge GST if its total value of imported services and low-value goods exceeds S$1,000,000 in a 12-month period, and it would not be entitled to full input tax credit if it were GST-registered.
• OVR registration threshold: overseas suppliers must register if global annual turnover exceeds S$1,000,000 and B2C supplies of remote services and/or low-value goods to Singapore customers exceed S$100,000 in a 12-month period.
• Low-value goods threshold: goods imported by air or post valued at S$400 or below fall within the GST on imported goods regime rather than being relieved of GST entirely.
• Standard GST rate applied under both regimes: 9 percent.
• Filing frequency for OVR-registered overseas vendors: typically quarterly, similar to local GST-registered businesses, though simplified registration limits the input tax that can be claimed.

Cost and timeline

These thresholds and mechanics were phased in deliberately by IRAS: the original 2020 regime covered only digital services, and the 2023 expansion brought non-digital remote services (such as online consultancy, education and telemedicine consultations delivered by overseas providers) and low-value goods into scope. Businesses that assessed their exposure only once, at the 2020 launch, and never revisited it after the 2023 expansion are a common source of unintentional non-compliance, since a supplier that was correctly out of scope in 2021 may well be caught by 2026 if its Singapore customer base or product mix has changed.

For a Singapore business assessing reverse-charge exposure, the main cost is internal: a review of imported service contracts (software subscriptions, offshore management fees, professional services from overseas advisers) typically takes between one and three weeks for a mid-sized business, and ongoing quarterly reverse-charge computation adds modestly to GST return preparation time, commonly an additional S$200 to S$500 per return if outsourced. For an overseas vendor assessing OVR liability, registration via the simplified pay-only regime is free to apply for and IRAS typically processes applications within 10 working days; ongoing compliance costs for maintaining Singapore-specific GST tracking within a global billing system vary widely, from a few hundred Singapore dollars a quarter for a lean SaaS business to significantly more for a marketplace operator with complex vendor-level reporting.

Step-by-step process

1. Map imported spend. A Singapore business identifies all services and low-value goods procured from overseas suppliers over a rolling 12-month period and totals the value.
2. Test input tax recovery. If the business would not be entitled to full input tax credit on a notional local purchase of the same service, and the S$1,000,000 threshold is exceeded, reverse-charge applies.
3. Self-account for output tax on the imported value in the relevant GST return, then claim input tax to the extent the business’s normal recovery rate allows.
4. Overseas vendors assess their own liability against the global turnover and Singapore B2C supply thresholds, using actual or reasonably projected figures.
5. Register via the OVR simplified pay-only regime (for vendors with no input tax to claim) or standard registration (if input tax recovery is needed), through the myTax Portal overseas vendor pathway.
6. Charge GST at checkout on qualifying B2C supplies to Singapore customers and issue a simplified tax invoice or receipt showing the GST charged.
7. File returns on the applicable cycle and remit GST collected, retaining transaction-level records for at least 5 years.

Common mistakes and gotchas

The most common mistake among Singapore businesses is assuming reverse-charge only applies to obviously “imported” line items like offshore consulting fees, when in practice it also captures royalties, software-as-a-service subscriptions billed from an overseas entity, and even intercompany management charges from an overseas parent or affiliate. A second frequent error is businesses with a mixed supply profile (partly taxable, partly exempt) failing to recompute their input tax recovery rate each year, which changes both their reverse-charge exposure and the proportion of self-charged tax they can reclaim. On the OVR side, overseas vendors sometimes assume that because they already charge GST or VAT in their home jurisdiction, Singapore GST is somehow double taxation to be avoided; it is not, and Singapore GST must be charged and remitted separately and explicitly to Singapore customers. Marketplace operators also frequently misjudge who is treated as the supplier for GST purposes; under the “electronic marketplace operator” rules, the platform itself, not the underlying overseas merchant, can be treated as making the supply and required to register, which changes who bears the compliance burden.

A further gotcha is timing: because both thresholds are tested on a rolling 12-month basis, businesses and vendors that experience a single large one-off transaction, an unusually large software licence renewal on the reverse-charge side, or a marketing campaign spike in Singapore sales on the OVR side, can trip the threshold for a period even if their steady-state activity is well below it, and should monitor the rolling calculation rather than only reviewing figures once a year.

Practical checklist for finance teams

Finance teams handling reverse-charge for the first time should build a simple quarterly checklist: list every overseas supplier invoice above a de minimis amount, tag each as a service, digital product, or low-value goods import, confirm whether the underlying supply would be exempt or taxable if made locally, and only then apply reverse-charge to the exempt-attributable proportion. This is far less error-prone than attempting to reconstruct a year’s worth of intercompany charges at year-end, particularly where intercompany management fee invoices are irregular in format and description.

Overseas vendors, meanwhile, benefit from building Singapore GST logic directly into checkout systems rather than relying on manual quarterly true-ups, since the customer-facing GST charge must be accurate at the point of sale, not merely reconciled afterwards. Marketplace operators in particular should document, in writing, which entity in the transaction chain is legally treated as the supplier for GST purposes, because this allocation determines who registers, who charges GST, and who bears responsibility if IRAS later disputes the position.

How this interacts with wider corporate structuring

Businesses restructuring cross-border operations, including family offices evaluating the 13O/13U/13D schemes, should factor reverse-charge exposure into any decision to centralise procurement or shared services offshore, since doing so can convert previously untaxed intercompany charges into reverse-charge liabilities; see our related guide on GST for e-commerce and digital services in Singapore. Companies bringing in overseas talent to manage these cross-border billing arrangements should also review pass eligibility in parallel; our partner site’s guide on when an S Pass job-scope change requires a fresh application is a useful cross-reference when a hire’s role shifts to cover new cross-border finance responsibilities.

FAQs

Does reverse-charge apply to a fully taxable business?
Generally no. Reverse-charge is designed for businesses that cannot fully recover input tax; a fully taxable business that could claim 100 percent input tax on a notional local purchase is not required to self-account under the regime.

Do I need to register for OVR if I already charge VAT overseas?
Yes, if you meet the Singapore-specific thresholds. Singapore GST registration and charging obligations are separate from tax obligations in your home jurisdiction.

What counts as a low-value good under these rules?
Goods imported by air or post valued at S$400 or below, which would otherwise have been relieved of GST at the border, are instead brought within the GST net through the OVR and reverse-charge framework.

Can an overseas vendor claim input tax under the simplified OVR regime?
No. The simplified pay-only registration does not allow input tax claims; vendors needing to recover Singapore input tax must register under the standard regime instead.

How often do these thresholds need to be reviewed?
Both the reverse-charge and OVR thresholds are tested on a rolling 12-month basis, so businesses and vendors should review exposure at least quarterly rather than only at financial year-end.

For the registration and filing basics that sit alongside these two regimes, see our companion piece, GST self-billing arrangements in Singapore. The description of exempt supplies relevant to input tax recovery calculations is set out in the Fourth Schedule to the Goods and Services Tax Act 1993, and zero-rating for qualifying international services is set out in section 21(3) of the Goods and Services Tax Act 1993; both should be read alongside the current IRAS e-Tax Guide on GST: Reverse Charge, which is updated more frequently than the underlying statute.
