Overseas e-commerce seller using a marketplace while some stock is already in the UK

A non-UK seller thinks the marketplace completely takes over VAT once the products are listed on a major platform.

The situation

A seller based in Hong Kong uses a marketplace to sell small consumer goods to UK customers. Some goods are shipped directly per order, but some are already stored in the UK through a fulfilment arrangement. The founder keeps repeating that 'the marketplace does the VAT now' and has stopped thinking about the rest of the workflow.

What matters first

HMRC's guidance splits the problem by inventory location and consignment structure. For consignments of £135 or less sold through a marketplace, the marketplace often accounts for VAT at the point of sale. HMRC also says online marketplaces are liable for VAT on goods already in the UK at the point of sale when sold by a seller not established in the UK. So the founder is partly right that the platform can carry the VAT-accounting burden in important cases.

What still does not disappear

The same HMRC material also says the seller can still be liable for import VAT and customs duty at the point goods are imported into the UK. It also leaves open registration and exemption questions for overseas sellers depending on their facts. That means marketplace liability for output VAT on a sale does not automatically clean up everything upstream and downstream.

What the next step should look like

The founder needs a map of where stock sits, how consignments are structured, whether sales are marketplace sales or direct sales, and who the customer is. This is not a one-sentence marketplace problem. It is an inventory, import and VAT-liability workflow. Once the founder sees it that way, the UK compliance picture becomes much less mysterious.

Action checklist

  • 1Map stock held outside the UK separately from stock already in the UK.
  • 2Test whether the sale falls within the marketplace rules for consignments of £135 or less.
  • 3Check import VAT and customs obligations separately from sale-stage VAT treatment.
  • 4Do not assume marketplace liability means the overseas seller has no registration or compliance tasks left.
