UK Marketplace VAT Rules Explained: What Amazon, eBay & Etsy Sellers Need to Know
If you sell on Amazon, eBay, or Etsy, you’ve probably noticed that VAT doesn’t always work the way you’d expect. Sometimes the marketplace charges and collects VAT on your behalf. Other times, it’s entirely down to you. Get it wrong, and you risk under-reporting sales, missing registration deadlines, or filing VAT returns that don’t reconcile with what the marketplace actually paid HMRC.
This confusion isn’t surprising. Marketplace VAT for UK sellers operates on a split system: who’s liable depends on where you’re established, where your stock sits, and the value of each order. And it’s about to get more complicated — HMRC is actively consulting on extending these rules further. Here’s exactly how the system works today, and what to watch for.
Who’s Actually Liable for VAT: You or the Marketplace?
Under current UK rules, liability depends on two factors: your business’s country of establishment, and where the goods are physically located at the point of sale.
- UK-established sellers with stock already in the UK remain liable for their own VAT. You register once your taxable turnover crosses £90,000, charge VAT yourself, and file your own returns.
- Overseas sellers (businesses not established in the UK) fall under “deemed supplier” rules in two scenarios: when goods are imported into the UK in consignments worth £135 or less, or when the goods are already sitting in a UK warehouse (such as an Amazon FBA facility) at the time of sale. In both cases, the marketplace — not the seller — collects VAT at checkout and remits it directly to HMRC.
Example: A seller based in Germany stores stock in an Amazon UK fulfilment centre. When a UK customer buys that item, Amazon is legally the deemed supplier — it collects the VAT and pays it to HMRC. The German seller never touches that VAT, but still needs to track the sale correctly for their own accounting.
A UK-based seller in the same warehouse, selling the same product, remains fully responsible for their own VAT — Amazon does not collect it on their behalf.
Marketplace Facilitated VAT: What Amazon, eBay & Etsy Actually Do
Each platform applies the deemed supplier rules slightly differently in practice, though the underlying legislation is the same.
- Amazon automatically applies deemed supplier VAT to qualifying transactions and reflects this in your Seller Central VAT transaction reports — it’s essential to reconcile these against your own ecommerce bookkeeping records rather than assuming they match your general sales figures.
- eBay applies the same logic for cross-border and low-value imported goods, collecting VAT at checkout where the rules require it.
- Etsy follows the identical framework: for qualifying low-value imports or overseas-seller UK stock sales, Etsy collects VAT from the buyer and remits it, rather than the seller.
The practical challenge for sellers is that a single month’s sales can include a mix of transactions — some where the marketplace collected VAT, and some where you’re still liable. Your bookkeeping needs to separate these correctly, or your VAT return will misstate your position.
Common VAT Mistakes UK Sellers Make
Even experienced sellers trip up on marketplace VAT. The most frequent errors include:
- Double-counting VAT — charging VAT on sales where the marketplace has already collected it as deemed supplier, effectively overcharging the customer or misreporting output tax
- Missing the £90,000 threshold — failing to monitor cumulative UK taxable turnover across all sales channels combined, not just one platform
- Ignoring cross-border stock movements — not realising that storing inventory in an overseas fulfilment centre can trigger local VAT registration obligations in that country
- Reconciliation gaps — treating marketplace payout reports as gospel without checking that reported VAT collection matches actual transaction-level data
- Overlooking input VAT recovery — missing legitimate VAT reclaims on marketplace fees, since platform fees often carry recoverable VAT
Getting any of these wrong doesn’t just risk penalties — it distorts your actual profit margins, since VAT errors ripple through your reported revenue and costs.
What’s Changing: The Push to Extend Deemed Supplier Rules
As of mid-2026, HMRC ran a formal consultation proposing to extend deemed supplier rules to UK-established sellers with UK-located stock — not just overseas sellers. Under the proposal, marketplaces like Amazon, eBay, and Etsy would collect and remit VAT directly for domestic sellers too, effectively removing the £90,000 threshold benefit for marketplace transactions and changing how payouts are calculated.
This isn’t law yet, and the consultation period has closed with no confirmed implementation date. But the direction of travel is clear: HMRC wants VAT collected at the platform level wherever possible, since it’s easier to enforce than chasing individual sellers. If you sell UK-stocked inventory through a marketplace, it’s worth watching this space closely, since a change here would directly affect your net payouts and pricing strategy.
Because this is an evolving area, it’s worth checking HMRC’s latest guidance or speaking with a specialist accountant before making long-term pricing or registration decisions based on today’s rules alone.
How to Stay Compliant as Marketplace VAT Rules Evolve
Given the complexity — and the likelihood of further change — a few practical habits will keep you in a strong position:
- Reconcile marketplace VAT reports monthly, not just at VAT return time, so discrepancies get caught early
- Track your UK taxable turnover across all channels, since the £90,000 threshold applies to your business as a whole, not per platform
- Use ecommerce-specific accounting software (such as A2X or Link My Books) that automatically separates deemed supplier VAT from seller-liable VAT
- Review your inventory locations regularly, since moving stock into a new country can trigger fresh VAT obligations
- Work with an accountant who understands marketplace VAT specifically, rather than general VAT rules, given how often platform-level nuances get missed
Final Thoughts
Marketplace VAT for UK sellers isn’t a single, fixed rulebook — it’s a system that shifts depending on where you’re established, where your stock sits, and increasingly, on regulatory changes still working their way through consultation. Getting it right protects your margins and keeps you off HMRC’s radar for the wrong reasons.
If you’re unsure whether you’re correctly separating deemed supplier transactions from your own VAT liability — or want help preparing for potential rule changes — book a consultation with an ecommerce VAT specialist to review your current setup. blooketplay
