Since the landmark changes in 2021, the responsibility for VAT on e-commerce has shifted firmly onto Online Marketplaces (OMPs) like Amazon and eBay. However, as we move through 2026, the landscape is shifting again. With HMRC’s digital systems now fully integrated with marketplace data, the focus has moved from understanding the rules to demonstrating absolute compliance.
In this guide, we break down the 2026 tax environment for marketplace sellers and the major EU customs reform arriving this July.
Why the Focus Has Shifted to Enforcement
When these rules were first introduced, the goal was to recover £1.5 billion in lost VAT. Today, HMRC’s approach is data-driven:
- Real-Time Data Sharing: Marketplaces now provide HMRC with direct access to seller transaction data. Discrepancies between your declared sales and marketplace reports are flagged automatically.
- Audit Scrutiny: HMRC is increasingly targeting overseas sellers who hold stock in UK fulfilment centres (FBA), as this creates an immediate VAT obligation regardless of turnover.
- Making Tax Digital (MTD): As of 2026, all VAT-registered businesses must use MTD-compatible software. The “paper trail” is now entirely digital, leaving no room for manual errors.
How Marketplace VAT Collection Works in 2026
The “Deemed Supplier” rule remains the standard. The marketplace is responsible for collecting and remitting VAT at the point of sale in two main scenarios:
- Imports: For goods sent from outside the UK to a UK consumer, the marketplace collects VAT at checkout.
- Goods Already in the UK: If an overseas seller stores goods in a UK warehouse (e.g., Amazon FBA), the marketplace is liable for the VAT on the sale to the consumer, regardless of the item’s value.
Expert Note: While the marketplace collects the tax, the seller is still responsible for registering for UK VAT and filing Nil or Deemed Supply returns to account for the movement of stock.
The 2026 EU Customs Reform: The €3 Flat Fee
For sellers trading into Europe, a major change is arriving on July 1, 2026.
- Abolition of the €150 Duty Relief: Historically, goods under €150 were duty-free. This ends in 2026.
- The €3 Per-Item Duty: To simplify the transition, the EU is introducing a temporary €3 customs duty per item for low-value e-commerce parcels. This is separate from VAT and will apply to goods declared via the Import One-Stop Shop (IOSS).
- Landed Cost Impact: Sellers must update their pricing models now to account for this per-item charge, or risk customers being charged unexpected fees upon delivery.
