If you're an Amazon seller in the UK, VAT is probably the single most complex part of your accounting — and the area where most generalist accountants get things badly wrong. We've seen it first-hand: sellers overpaying VAT for years without realising it, others unknowingly non-compliant with EU rules, and many simply treating their Amazon payout as revenue when it's not.

This guide covers everything you need to know about VAT as a UK Amazon seller in 2025 — from registration thresholds to EU OSS, Amazon VAT Services, and the specific mistakes we see most often.

💡 We recovered £20,000 in overpaid VAT for one of our Shopify and Amazon seller clients in our first month of working with them. This guide explains exactly how that happens — and how to make sure it's not happening to you.

1. UK VAT Registration Threshold — When Do You Have to Register?

The UK VAT registration threshold is currently £90,000 in taxable turnover over a rolling 12-month period. If your Amazon sales exceed this, you must register for VAT.

The critical mistake most sellers make: They calculate their turnover based on their Amazon payout — the money that lands in their bank account. But your VAT turnover is your gross sales value, not your net payout. Amazon's fees, FBA costs, and refunds don't reduce your VAT turnover for the purpose of the threshold calculation. This means many sellers breach the £90,000 threshold months before they realise it.

2. Which VAT Scheme Is Right for Amazon Sellers?

Once registered, you need to choose the right VAT scheme. Most Amazon sellers default to the Standard VAT scheme — but this isn't always optimal.

Standard VAT Scheme

You charge 20% VAT on sales (where applicable) and reclaim VAT on business purchases. Works well if you have significant VAT-able expenses — including import duties, Amazon fees (which are VAT-able for UK registered businesses), and stock purchases from VAT-registered UK suppliers.

Flat Rate Scheme

You pay a fixed percentage of your gross turnover to HMRC instead of calculating VAT on every transaction. The rate depends on your sector — for most retail businesses it's around 7.5%. This can be advantageous for Amazon sellers with low input VAT — particularly those dropshipping or buying from non-VAT registered suppliers. The maths: if your flat rate is 7.5% and you're paying 20% VAT on sales but have minimal input VAT to reclaim, the flat rate scheme means you keep more.

Cash Accounting Scheme

You account for VAT based on when money is received and paid, rather than invoice date. Less relevant for Amazon sellers since Amazon pays out on a set schedule, but worth considering if you have large B2B sales with payment terms.

⚠️ The right VAT scheme depends on your specific cost structure. We always model both standard and flat rate for new clients before recommending one — the difference can be thousands of pounds per year.

3. Amazon VAT Services — What It Does and What It Doesn't

Amazon offers a VAT Services on Amazon programme that automatically files your EU VAT returns. This sounds like a complete solution — but there are important limitations your accountant needs to understand.

What Amazon VAT Services does:

What it doesn't do:

The reconciliation problem: Amazon VAT Services generates its own reports, but these often don't match the data in your accounting software. Without proper reconciliation, you can end up with VAT figures that are materially different from your actual liability. This is one of the most common issues we find when onboarding new Amazon seller clients.

4. EU VAT and OSS — The Post-Brexit Landscape

Since Brexit, UK sellers shipping goods into the EU need to navigate a more complex VAT landscape. The key framework is the EU VAT One Stop Shop (OSS).

When Do You Need EU VAT Registration?

If you're selling goods to EU consumers (B2C) and your cross-border EU sales exceed €10,000 per year, you're required to either:

OSS is almost always the right choice for UK Amazon sellers — it's a single registration, single quarterly return, and single payment, rather than managing registrations in 27 different countries.

OSS Registration for UK Sellers

As a UK-based business, you can register for EU OSS through any EU member state — most of our clients register in Ireland or Germany for practical reasons. Once registered, you file quarterly returns reporting all B2C EU sales and pay the VAT to one country, which distributes it to the relevant member states.

Amazon FBA Pan-European Programme and VAT

If you're on Amazon's Pan-European FBA programme, Amazon can store your inventory in warehouses across multiple EU countries. This creates a VAT registration obligation in each country where your stock is held — regardless of where your customers are. This is separate from OSS and is one of the most frequently misunderstood VAT issues for Amazon sellers.

5. Making Tax Digital for VAT — What Amazon Sellers Need to Know

All VAT-registered businesses are now required to keep digital records and submit VAT returns using MTD-compatible software. For Amazon sellers, this means:

The penalty for non-compliance with MTD is a points-based system — accumulate enough points and you'll face financial penalties. Most sellers are compliant without realising it if they're using Xero or QuickBooks properly, but the underlying data quality matters.

6. The 5 Most Common VAT Mistakes We See Amazon Sellers Make

Based on onboarding dozens of Amazon and ecommerce seller clients, here are the mistakes we see most frequently:

Mistake 1: Using Amazon Payout as Revenue

Amazon pays out net of fees, refunds, FBA charges, and other deductions. Treating this as your gross revenue means your VAT return is understating your actual sales — and your P&L is showing artificially high margins. Use A2X or Link My Books to pull the correct gross figures.

Mistake 2: Missing the VAT Registration Threshold

As mentioned above — your VAT threshold is based on gross sales, not Amazon payouts. Sellers frequently breach £90,000 and don't realise it for months. HMRC will back-date your registration and you'll owe VAT on all those sales retrospectively, plus interest and potentially penalties.

Mistake 3: Wrong VAT Rate on Products

Not all products are standard-rated at 20%. Some are zero-rated (most food, children's clothing, books) or exempt. If your listings are set up with the wrong VAT rate in your accounting software, your returns will be wrong. Amazon's own product taxonomy doesn't always match HMRC's VAT rules.

Mistake 4: Ignoring EU OSS When Selling Cross-Border

Many UK Amazon sellers with EU customers haven't registered for OSS — they're technically non-compliant and accumulating a growing VAT liability they're not aware of. The €10,000 threshold is low and many sellers breach it without realising.

Mistake 5: Not Reclaiming Import VAT

If you import goods into the UK from outside the UK, you pay import VAT at the border. This is reclaimable as input VAT on your UK VAT return — but only if you have the correct C79 certificate from HMRC and your accountant knows to include it. Many sellers lose this reclaim entirely.

7. Setting Up Xero Correctly for Amazon Sellers

The right technical setup makes all of this manageable. Here's how we configure Xero for Amazon seller clients:

When this is set up correctly, your VAT return takes minutes rather than hours, your margins are visible by channel, and you have full audit trail for HMRC.

📊 We set this up for every new Amazon seller client as standard. Most clients are fully live within one week of onboarding.

Summary: What to Do Next

If you're an Amazon seller and any of the above is unclear or not currently handled, here's your immediate action list:

  1. Check your gross sales (not Amazon payouts) for the last 12 months — are you near or above £90,000?
  2. Confirm you're registered for VAT if required, and that your registration date is correct
  3. Check whether you're on the right VAT scheme for your cost structure
  4. If you sell to EU customers and your cross-border sales exceed €10,000, confirm EU OSS registration is in place
  5. Review how your Amazon data feeds into your accounting software — are you using A2X or Link My Books?
  6. Ask your accountant specifically how they handle Amazon payout reconciliation — if they're not familiar with A2X or Link My Books, that's a red flag
