There is no single worldwide VAT or GST registration threshold. Overseas-seller regimes can use different turnover tests, customer definitions and transaction scopes from domestic regimes. Build the assessment by legal entity and sales model before comparing numbers; a local warehouse, consumer service or marketplace sale may follow a different route.
Key takeaways
Record where the seller is established and where inventory is stored.
Separate remote services, imported goods and domestic supplies before measuring turnover.
Global revenue and local consumer revenue can be two distinct registration tests.
Confirm who is legally responsible when a marketplace or other intermediary is involved.
Map the supply chain before collecting thresholds
For each market, identify the seller of record, customer type, place of establishment, dispatch location, importer and party responsible for the checkout tax. A company shipping goods from its home country can have a different analysis from the same company stocking those goods locally. Remote services require another analysis because no parcel crosses customs. A country-level revenue total hides these differences.
Create separate lanes for direct consumer sales, verified business sales, marketplace transactions and domestic inventory sales. Record when each lane began and which entity made the supply. This factsheet should precede threshold research: otherwise a team may apply a domestic small-business threshold to a non-established supplier or overlook a registration obligation created by local stock.
Read threshold conditions, not just the headline number
The UK generally uses a £90,000 taxable-turnover registration threshold for the relevant domestic tests, but a business based outside the UK can have a registration obligation for UK taxable supplies without that threshold. HMRC's registration guidance distinguishes these situations. This is why a small overseas seller should not treat a familiar domestic threshold as automatic permission to ignore a market.
Singapore's overseas vendor registration regime uses both annual global turnover exceeding S$1 million and covered B2C supplies of remote services or low-value goods to Singapore exceeding S$100,000. Maintain those measures separately and check the regime's definitions and testing rules. In New Zealand, overseas remote-service suppliers should review the NZ$60,000 test and the treatment of GST-registered business customers in Inland Revenue's guidance.
Make a decision record that survives an audit
Build a market register with columns for entity, supply lane, applicable regime, counted revenue, excluded revenue, measurement window, currency conversion, trigger date and next action. Link the official guidance and the source report that supports the number. Distinguish 'below the applicable threshold' from 'outside this regime' and 'facts incomplete'; those are different conclusions with different monitoring needs.
For an illustrative Singapore review, assume a vendor has S$1.2 million in global turnover and S$110,000 of covered Singapore consumer supplies in the relevant annual test. Both headline amounts exceed the OVR thresholds, so the team should complete the regime-specific registration analysis rather than treating only local revenue as relevant. If global turnover were S$800,000, the same two-test analysis would not produce the same result. Other obligations still need a separate assessment.
Handle marketplaces and simplified schemes explicitly
A platform collecting tax is an important fact, but it does not automatically resolve the seller's direct website sales, local stock or reporting obligations. Obtain evidence of the platform's role, covered transactions and effective date. Separate its consumer tax from fees and taxes charged to the merchant. Reconcile the platform reports to orders so each sale has an identified collector and reporting route.
EU OSS and IOSS are examples of simplification schemes with defined scopes, not global replacements for VAT registration. Goods already held in an EU warehouse do not become imported low-value consignments merely because the seller is outside Europe. Select the correct route for the physical supply chain and keep customs, import VAT and consumer checkout VAT distinct. Our IOSS guide for US sellers explains that particular imported-goods route.
Turn a registration decision into an operating launch
Once registration is required, record the application deadline, requested effective date, account owner, invoice requirements, filing frequency and payment method. Prepare the company's identity and establishment evidence, banking details and representative information required by the authority. Verify the approved registration and effective date before enabling a jurisdiction in billing, and test both consumer and business transactions using the approved scope.
Set ongoing checks for threshold growth, new inventory locations, changed platforms and new product types. Reconcile registered-country revenue to return populations and investigate sales that remain outside every reporting route. When leaving a market, check deregistration and final-return requirements rather than simply disabling the tax setting. Preserve the market register, registration documents, original calculations and closure confirmation so a later expansion can start from a defensible history.
Frequently asked questions
Can one VAT registration cover every country?
No. Each jurisdiction has its own rules. Some schemes simplify reporting for specified transactions across a region, but they do not cover all countries or all supplies.
Does selling only through a marketplace remove registration duties?
It depends on the platform's legal role and the seller's other activities. Direct sales, local inventory and domestic transactions can require a separate analysis.
How often should an overseas seller check thresholds?
Use a cadence that detects a trigger before the applicable deadline, and reassess immediately after changes in establishment, inventory, supply model or customer mix. Monthly monitoring is a practical starting point, not a universal legal interval.
