VAT for Amazon FBA sellers involves more moving parts than for most businesses. You may be selling across multiple marketplaces, holding stock in multiple countries, dealing with import VAT on goods from overseas suppliers, and navigating post-Brexit rules for EU sales. Getting any one of these wrong can result in penalties, backdated liabilities and account suspension.

This guide covers the full picture for UK FBA sellers.

The Basics: How VAT Works

VAT is a 20% tax on goods and services in the UK. When you are VAT-registered you charge VAT on your sales (output VAT), reclaim VAT on your business expenses (input VAT), and pay HMRC the difference each quarter. If your input VAT exceeds your output VAT in a period, HMRC refunds the difference.

For Amazon FBA sellers investing heavily in inventory ahead of peak periods, quarterly VAT refunds can be significant. Getting your registration and returns right means you receive these refunds on time rather than leaving cash tied up unnecessarily.

When Do UK FBA Sellers Need to Register for VAT?

You must register for UK VAT once your taxable turnover exceeds £90,000 in any rolling 12-month period. Turnover means total sales revenue, not profit. Once you cross the threshold, you must register within 30 days.

You must also register if you expect your turnover to exceed £90,000 in the next 30 days alone, for example if a large order or promotion is about to push you over.

How the threshold works
Rolling 12-month sales (Jan to Dec)£95,000
VAT threshold£90,000
Threshold exceeded by£5,000
Result: VAT registration required within 30 days

Monitor rolling turnover monthly, not just at year end. HMRC uses a rolling 12-month window. If you check only at the end of the tax year you may miss the point at which you crossed the threshold mid-year, creating a backdated liability.

Can You Register Voluntarily?

Yes. You can register for VAT even if your turnover is below £90,000. This makes sense if you have substantial VAT-deductible expenses and your customers are primarily VAT-registered businesses who can reclaim the VAT you charge. It is less attractive if you sell primarily to consumers, as your effective prices rise by 20%.

How UK FBA VAT Works in Practice

Once VAT-registered and selling on Amazon.co.uk:

  • You charge 20% VAT on your UK sales
  • Amazon adds VAT to the customer order automatically
  • You report output VAT on your quarterly return
  • You reclaim input VAT on qualifying business expenses
UK sale example
Product listed price (ex-VAT)£50.00
VAT at 20%£10.00
Customer pays£60.00
You keep £50, £10 goes to HMRC (minus input VAT reclaimed)

Important: Amazon fees do not carry UK VAT. Amazon UK marketplace fees are charged by Amazon EU S.a.r.l, based in Luxembourg. This means no UK VAT applies to Amazon fees and you cannot reclaim input VAT on them. This is one of the most common errors in FBA seller bookkeeping.

EU VAT and Pan-European FBA

If you sell across EU Amazon marketplaces (Amazon.de, Amazon.fr, Amazon.it, Amazon.es and others), VAT becomes significantly more complex. The key issue is deemed supply.

Deemed Supply and EU VAT Registration

Under EU VAT rules, storing inventory in an EU country creates a deemed supply, which triggers VAT registration obligations in that country. If you use Amazon's Pan-European FBA programme, Amazon may distribute your stock to warehouses in Germany, France, Poland, Italy and elsewhere without you specifically requesting it.

Each country where your stock is held may require a local VAT registration. Ignoring deemed supply obligations can result in VAT penalties across multiple countries, backdated liabilities and Amazon account suspension.

One Stop Shop (OSS)

The EU's One Stop Shop (OSS) scheme simplifies cross-border VAT compliance for distance selling to EU consumers (B2C). Instead of registering for VAT in every EU country separately, you register for OSS in one EU country and declare all EU VAT through a single quarterly return.

  • Applies to B2C distance sales across EU borders
  • Available once EU-wide cross-border sales exceed the threshold of 10,000 euros per year
  • Does not remove the obligation to register locally where stock is physically held

Import VAT on Goods Entering the EU

When you send goods from the UK to an EU Amazon warehouse, import VAT is due when the goods enter the EU. The options are:

  1. Pay import VAT upfront when goods clear EU customs
  2. Use postponed VAT accounting if you hold an EU VAT number in the destination country
  3. Use Amazon's Import One-Stop Shop (IOSS) for individual consignments under 150 euros

Working with a freight forwarder who understands Amazon FBA and post-Brexit VAT rules is strongly recommended for any seller shipping regularly to EU warehouses.

VAT Schemes: Which One Is Right for You?

Standard VAT accounting

Best for most FBA sellers

Charge 20% VAT on sales. Reclaim input VAT on all qualifying expenses. Pay HMRC the net difference each quarter.

  • Reclaim VAT on inventory, advertising, software and shipping
  • More admin but more accurate for high-expense businesses
  • HMRC refunds you if input VAT exceeds output VAT in a period
Flat Rate Scheme

Rarely suitable for FBA sellers

Charge 20% VAT. Pay HMRC a fixed percentage of gross turnover (around 7.5% for retail). Cannot reclaim input VAT on expenses.

  • Less admin but you lose all input VAT reclaims
  • Works for low-expense businesses only
  • Most FBA sellers have too many expenses to benefit
  • Turnover must be under £150,000 to join

VAT Margin Scheme for Second-Hand Sellers

If you resell second-hand goods, you may be eligible for the VAT Margin Scheme. Under this scheme, you charge VAT only on your profit margin rather than the full selling price. This is particularly relevant for FBA sellers who buy and resell used items, collectibles, trading cards or antiques that were purchased without VAT.

Margin Scheme example
Purchase price (no VAT paid)£50
Selling price£100
Margin£50
VAT charged (on margin only)£8.33
vs standard VAT (on full price): £20.00

Strict eligibility and record-keeping rules apply. Read our dedicated guide on Amazon FBA accounting, VAT, inventory and multi-currency sales for more detail.

Making Tax Digital for VAT

All VAT-registered businesses must keep digital VAT records and submit returns using Making Tax Digital-compatible software. You cannot submit VAT returns manually through the HMRC website. Compatible software includes Xero, QuickBooks, Sage and FreeAgent. For Amazon FBA sellers, integrating A2X with Xero or QuickBooks automates the import of Amazon settlement data and significantly reduces manual bookkeeping.

Common VAT Mistakes Amazon FBA Sellers Make

Not registering on time. HMRC backtracks your registration and demands VAT on sales you may not have collected from customers. Monitor rolling 12-month turnover monthly.
Claiming input VAT on Amazon fees. Amazon fees carry no UK VAT. Treating them as VAT-inclusive in your bookkeeping overclaims input VAT and creates errors on your return.
Ignoring deemed supply for Pan-European FBA. If Amazon distributes your stock to EU warehouses, you may have VAT registration obligations across multiple countries. Get specialist advice before joining Pan-EU FBA.
Not keeping VAT records for six years. HMRC can request VAT invoices, sales records and returns going back six years. Cloud accounting software makes this straightforward.
Poor cash flow planning. You collect VAT from customers throughout the quarter but pay HMRC in one lump sum. Keep VAT receipts in a separate account so the quarterly payment does not cause a cash flow problem.
