UK VAT treatment depends on where goods are located at sale, consignment value, customer status, and whether an online marketplace facilitates the order. Overseas sellers should map each supply chain before deciding who charges VAT and when import VAT applies.
Key takeaways
Overseas businesses making taxable direct sales in the UK can need VAT registration without relying on the normal domestic threshold.
For qualifying consignments not exceeding £135, VAT is generally collected at the point of sale rather than solely at import.
A qualifying online marketplace can be deemed to make the supply and become responsible for VAT on covered transactions.
Goods already located in the UK, B2B orders, imports over £135, Northern Ireland movements, and direct sales require distinct analysis.
Start with the supply chain, not the checkout rate
Identify the legal seller, customer, marketplace, payment flow, inventory location when the order is accepted, dispatch country, delivery destination, importer of record, and consignment value. These facts decide whether the transaction is a domestic supply, a distance sale involving importation, or a marketplace-deemed supply.
Do not treat the United Kingdom as one generic cross-border configuration. Great Britain and Northern Ireland can interact differently with goods rules, and customs consequences remain separate from VAT collection. Document the route for each fulfillment model before launching it.
- Map direct, marketplace, and wholesale channels separately.
- Record where goods are located at the time of sale.
- Identify the importer of record and customs declarant.
- Escalate Northern Ireland movements for specific review.
Direct sales and the £135 consignment rule
For goods outside the UK sold directly to customers in Great Britain in consignments valued at £135 or less, the seller generally charges UK VAT at the point of sale. The £135 test applies to the total consignment value, not automatically to each product, and excludes transport and insurance when separately shown for this purpose.
B2B treatment can differ where the customer provides a valid UK VAT number and the statutory conditions are met. Consignments over £135 generally fall into import VAT and customs processes, with the later domestic sale depending on the commercial terms and importer. Split shipments designed only to change tax treatment create operational and compliance risk.
- Store consignment-level value and currency conversion.
- Collect and validate business VAT details where relevant.
- Keep Incoterms and importer responsibility visible.
- Test bundles, multiple parcels, refunds, and replacements.
Online marketplace deemed-supplier rules
A marketplace may be treated as making the supply when it facilitates covered sales by an overseas seller. The result depends on where goods are located, consignment value, customer type, and whether the platform meets the legal definition. A payment provider or advertising site is not automatically a marketplace for VAT.
Sellers should obtain platform reports showing tax responsibility by order and preserve contract terms, settlement statements, refunds, and VAT invoices. Continue reviewing direct sales and inventory because marketplace collection does not erase every registration, recordkeeping, customs, or reporting obligation.
- Confirm the platform rule for each transaction flow.
- Prevent duplicate VAT collection by seller and marketplace.
- Reconcile platform tax separately from seller-collected VAT.
- Retain evidence of marketplace responsibility.
Registration, invoices, returns, and import VAT
After confirming an obligation, register before charging VAT and configure invoices with the correct supplier details, rate, net amount, VAT amount, and required references. Determine whether postponed VAT accounting or another import-VAT mechanism is available based on importer status and records; customs duty is not input VAT.
Reconcile sales by channel and rate, output VAT, credit notes, bad-debt adjustments, imports, marketplace transactions, and recoverable input VAT before each return. Link import VAT claims to customs evidence and the correct legal entity. Preserve Making Tax Digital records and digital links where the rules apply.
- Keep VAT and EORI identifiers with the correct entity.
- Match credit notes to original invoices.
- Reconcile customs statements to imports.
- Retain accepted returns and payment confirmations.
A launch checklist for overseas sellers
Before enabling UK orders, test one realistic transaction for every fulfillment and customer scenario: direct low-value B2C, higher-value import, marketplace sale, UK-stock sale, business customer, refund, replacement, and exempt or reduced-rate item. Confirm who displays, collects, invoices, refunds, and reports the VAT.
Assign owners for tax rules, customs data, marketplace reports, return preparation, and notices. Review official guidance whenever inventory moves, Incoterms change, a new platform is added, or the product catalog expands. Operational changes can alter the VAT answer even when customer demand is unchanged.
- Approve a written responsibility matrix.
- Keep product VAT mappings versioned.
- Monitor rejected imports and double-charge complaints.
- Schedule quarterly control testing.
Frequently asked questions
Do overseas sellers have a UK VAT registration threshold?
Overseas businesses making taxable UK sales can be required to register without using the normal domestic taxable-turnover threshold. The exact result depends on the transaction and establishment facts.
Does the £135 rule apply to each item?
The test generally looks at the total value of the consignment, excluding separately stated transport and insurance for the relevant calculation, rather than automatically treating each item separately.
Does a marketplace always pay UK VAT for the seller?
No. The platform must facilitate a transaction within the deemed-supplier rules. Direct sales and transactions outside scope remain the seller’s responsibility.
Is customs duty the same as import VAT?
No. Customs duty and import VAT are separate charges with different calculation, payment, and recovery rules.
