How to avoid VAT headaches when selling on Amazon FBA and Etsy in the UK: a practical checklist

Selling on Amazon FBA and Etsy is a brilliant way to scale a small business fast, but VAT can feel like a trapdoor if you don’t plan for it. I’ve helped lots of UK sellers untangle VAT headaches — missing registrations, lost VAT on fees, surprise import charges — and the same patterns keep repeating. Below I share a practical, no-nonsense checklist and the key rules I always walk clients through so you can stay compliant and avoid nasty surprises.

Start with the basics: where are your goods, who are you selling to?

The single most important thing to clarify is the location of your stock and the destination of your sales. It sounds basic, but it determines almost every VAT obligation.

• Stock stored in the UK: If you or a third party (like Amazon FBA UK warehouses or a UK fulfilment partner) hold stock in the UK, UK VAT rules apply and you’ll likely need to register for UK VAT if you make taxable supplies here.
• Stock stored abroad: If you use Amazon FBA in other countries (eg, EU warehouses), you can trigger VAT obligations in those countries — you may need local VAT registrations, or to use OSS/IOSS depending on the flow.
• Who’s the customer? Selling B2C to UK consumers is different from B2B; business customers normally provide a VAT number and reverse-charge can apply (for certain cross-border sales).

Key VAT rules sellers frequently miss

These are the real pain points I see in the field.

• VAT registration threshold: If your taxable turnover in the UK exceeds £85,000 in any 12-month period, you must register. But storing stock in the UK can create a requirement to register even if turnover is below the threshold.
• Marketplace and fulfilment rules: Using Amazon FBA can create VAT obligations in any country where Amazon stores your stock. Marketplaces may also collect VAT on certain sales or imports — but you can’t assume they’ll handle everything for you.
• Import VAT & customs: Imported stock usually attracts import VAT and possibly customs duty on arrival. How you account for and recover that VAT depends on whether you import as a business and whether you defer VAT via a Duty Deferment Account or use postponed VAT accounting.
• Accounting for VAT on marketplace fees: Fees charged by Amazon/Etsy are typically subject to VAT (if the seller or marketplace is UK VAT-registered). Treat these fees as a business expense and reclaim VAT where appropriate.
• Second-hand goods and margin schemes: If you trade in used goods, the VAT margin scheme may apply — this affects how you account for VAT on sales.

Practical checklist: what I make my clients do first

How to handle Amazon and Etsy specifics

Both platforms help sellers reach customers, but they don’t replace your VAT responsibilities.

• Amazon FBA:
  • Amazon will often transfer your inventory between its fulfilment centres (including overseas) — this can create unexpected VAT registrations in those countries. Keep a map of where your SKUs are stored.
  • Use Amazon’s VAT Calculation Service if you want help calculating VAT at checkout, but don’t rely on it for compliance or registrations.
  • Record Amazon’s fees separately in your bookkeeping. If the invoice includes VAT, reclaim it if you’re entitled to.
• Etsy:
  • Etsy may collect and remit VAT on certain cross-border sales (depending on local rules and the product type). Check Etsy’s policies for seller VAT responsibilities in each market you sell to.
  • Ensure your listings show correct VAT-inclusive pricing where legally required and that you know whether VAT is accounted for by Etsy or remains your responsibility.

VAT schemes — which might suit small marketplace sellers?

A few schemes can reduce admin or help cashflow. I always weigh pros and cons for each business.

• Cash Accounting: Only pay VAT when you get paid — helpful if you have slow-paying customers.
• Flat Rate Scheme: Simplifies returns by applying a fixed percentage to turnover — can be good for low-VAT-cost businesses, but you can’t reclaim VAT on most purchases.
• Annual Accounting: Reduces the number of returns — suitable for stable businesses wanting fewer filings.

Record keeping and software — save time and reduce errors

Good software will save you hours and reduce risk on VAT audits. I recommend solutions that integrate with marketplaces and handle multi-currency and marketplace fees clearly.

• Xero and QuickBooks both have marketplace integrations and allow you to code Amazon/Etsy fees separately so your VAT control account stays tidy.
• Consider specialist tax tools like Avalara or Taxamo if you sell widely across borders — they automate VAT calculation and records for many marketplaces.
• Keep clear copies of import documentation, commercial invoices and customs paperwork — you’ll need these to reclaim import VAT or respond to HMRC queries.

Common mistakes and how to avoid them

• Assuming the marketplace handles everything: Marketplaces help, but they don’t replace your registration responsibilities in many situations. Check the fine print for each market and product type.
• Not tracking where stock sits: I’ve seen sellers with UK VAT bills because Amazon moved inventory to a UK warehouse without the seller realising. Automate inventory tracking.
• Mixing personal and business VAT records: Keep a dedicated business bank account and bookkeeping ledger to avoid messy VAT returns and lost reclaims.
• Failing to reclaim import VAT: If you’re importing as a VAT-registered business, ensure you record and reclaim import VAT correctly — it’s recoverable when properly documented.

If any of this sounds like a maze, break it down: identify where your stock is, check your turnover vs the threshold, register if needed, and put bookkeeping systems in place that separate marketplace fees, shipping and import VAT. If you want, I can walk through your specific setup (Amazon FBA regions, Etsy listings and invoicing) and help you build a tailored VAT checklist so you’re not left chasing paperwork later.
