Amazon FBA has made it possible to build a six or seven-figure business from a spare bedroom. But as your revenue grows, so does the complexity of your tax position. From Self Assessment and VAT to cross-border selling and potential incorporation, UK Amazon FBA sellers face tax challenges that a standard high-street accountant often isn’t equipped to handle. This guide covers everything you need to know.
Do Amazon FBA Sellers Pay Tax in the UK?
Yes. If your Amazon FBA income exceeds £1,000 in a tax year, HMRC requires you to register as self-employed and file a Self Assessment tax return. This applies whether you’re selling on Amazon.co.uk, Amazon.de, Amazon.com, or any other marketplace. If you’re a UK resident, your worldwide income is taxable in the UK.
Income Tax on Amazon FBA Profits
You pay Income Tax on your profits — that’s your total Amazon revenue minus your allowable expenses. UK rates for 2025/26:
- Up to £12,570 — Personal Allowance (0%)
- £12,571–£50,270 — Basic Rate (20%)
- £50,271–£125,140 — Higher Rate (40%)
You’ll also pay Class 4 National Insurance on profits above £12,570. Building a solid record of allowable expenses is critical to keeping your taxable profit as low as legally possible.
What Expenses Can Amazon FBA Sellers Claim?
- Cost of goods sold (your wholesale or manufacturing costs)
- Amazon fees (referral fees, FBA fulfilment fees, storage fees)
- Advertising spend (Amazon PPC, sponsored products)
- Packaging materials and supplies
- Freight, shipping, and customs duties
- Software (inventory management, repricing tools, keyword research tools)
- Home office costs if you work from home
- Professional fees including accountancy
- Business bank charges and interest on business loans
Keep every receipt and invoice. HMRC can review records up to six years after filing.
VAT for Amazon FBA Sellers — The Essentials
VAT is where Amazon FBA gets complicated. Here’s what you need to know:
UK VAT Registration
You must register for UK VAT when your taxable turnover exceeds £90,000 in any rolling 12-month period. Once registered, you charge VAT on applicable sales and can reclaim VAT on business purchases.
VAT and Goods Stored in EU Fulfilment Centres
If Amazon stores your inventory in EU warehouses (Germany, France, Italy, etc. via Pan-European FBA or EFN), you may have VAT obligations in those countries, even if your UK turnover is below the registration threshold. Post-Brexit, this remains an area of significant complexity.
Should You Incorporate as a Limited Company?
Most serious Amazon FBA sellers eventually consider incorporation. A limited company can offer meaningful tax savings:
- More tax-efficient profit extraction via dividends
- Limited liability — personal assets are protected if the business fails
- Easier to retain profits in the business for reinvestment
The additional admin of running a limited company (annual accounts, confirmation statements, etc.) is manageable with the right accountant and well worth it at scale. We can model both scenarios and show you the exact tax savings for your income level.
Making Tax Digital — What FBA Sellers Need to Know
From April 2026, self-employed individuals with gross income over £50,000 must use MTD-compatible software and file quarterly updates with HMRC. If your Amazon revenue exceeds this threshold, you need to be prepared. Working with a specialist accountant who already uses cloud-based tools makes this transition straightforward.
Common Tax Mistakes Amazon FBA Sellers Make
- Not registering for Self Assessment — HMRC will find undeclared income
- Missing the VAT registration threshold — penalties can be significant
- Ignoring overseas VAT obligations (EU fulfilment centres)
- Failing to claim all allowable expenses — especially Amazon fees, which are substantial
- Mixing personal and business finances — use a dedicated business bank account
- Not planning for Payments on Account — HMRC’s advance payment system catches many sellers off guard
