Complete Guide to Tax Rules for Amazon Sellers in the UK

Selling on Amazon is a fantastic way to grow an online business, but tax and compliance often cause confusion.  Many sellers manage listings and stock well but struggle with VAT, HMRC rules, and business registration. At Apex Accountants, we specialise in helping Amazon sellers, resellers, and FBA traders manage their finances efficiently. Our expert team understands the tax rules for Amazon sellers in the UK, including VAT obligations, income tax, corporation tax, and Making Tax Digital compliance.

This article answers common questions our tax experts receive from Amazon sellers about UK taxes, VAT thresholds, and reporting for 2025–26.

Do Amazon sellers pay tax in the UK?

Yes. Whether you’re selling part-time or running a full-scale online store, income from Amazon sales counts as taxable income. HMRC treats you as trading if your sales are regular and profit-driven.

The type of tax you pay depends on how your business is structured:

• Sole traders pay income tax and national insurance on profits.
  
• Limited companies pay corporation tax on company earnings.
  
• Partnerships file partnership tax returns and individual partner taxes.
  

As tax advisors, we often help new sellers determine the best structure to reduce tax exposure and stay compliant from day one.

When should Amazon sellers register for VAT?

VAT registration becomes mandatory when your taxable turnover exceeds £90,000 in any rolling 12-month period. The sellers choose to register earlier to reclaim VAT on purchases such as inventory, Amazon fees, and advertising costs.

We provide tailored VAT services for Amazon sellers, helping them understand thresholds and reclaim input VAT. Please ensure that you submit digital returns on time. It ensures your obligations are met while improving cash flow and operational efficiency.

Once registered, sellers must charge VAT, usually 20%, on UK sales, submit VAT returns digitally under Making Tax Digital (MTD), and pay HMRC any VAT owed after offsetting input VAT.

Many sellers misunderstand how Amazon fees interact with VAT. Since August 2024, Amazon has applied VAT to its seller charges — a cost that can be reclaimed if your business is VAT-registered.

What happens if I sell internationally through Amazon FBA?

Selling across borders introduces more complex VAT rules. If you use Fulfilment by Amazon (FBA) and store stock in other countries, you may need local VAT registrations.

Our team regularly supports sellers using the Pan-EU FBA or European OSS (One Stop Shop) scheme, helping them manage multiple VAT accounts while keeping records centralised.

In short, storing stock abroad usually means VAT registration abroad, selling it to EU consumers may trigger OSS reporting, and non-compliance can lead to foreign tax penalties. We simplify these rules so sellers can focus on sales rather than tax forms.

How do Amazon sellers pay Income Tax?

For sole traders, income tax is calculated on profits — not total revenue. Sellers must register for self-assessment and file returns each year.

The 2025–26 tax bands are:

• 0% up to £12,570 (personal allowance)
  
• 20% for basic rate
  
• 40% for higher rate
  
• 45% for additional rate
  

Deductible business costs can include Amazon fees, product sourcing, shipping, packaging, software, advertising, and accountancy services. We help clients identify legitimate deductions to avoid overpaying tax and to maintain full compliance with HMRC.

How is corporation tax applied to Amazon businesses?

If you trade through a limited company, your profits are subject to corporation tax rather than income tax. The main rate is 25% for profits above £250,000. The small profits rate of 19% applies below £50,000, and companies between those thresholds receive marginal relief.

Filing a corporation tax return involves more than submitting figures. We ensure our clients’ accounts, director pay, and dividends are correctly aligned to minimise liability and avoid compliance errors.

What records should Amazon sellers keep?

Amazon sellers are required by law to maintain digital financial records for at least six years. Key records include sales reports and payout summaries from Amazon, purchase invoices and supplier receipts, VAT returns and submissions, import documentation, advertising, shipping, and packaging costs, and bank reconciliations.

We assist clients with setting up efficient digital systems, offering Amazon bookkeeping services UK tailored to your specific business model. This includes integrating tools like QuickBooks, Xero, or A2X for automated, MTD-compliant recordkeeping.

Do Amazon sellers pay National Insurance?

Yes. If you operate as a sole trader, you’ll pay Class 2 and Class 4 National Insurance Contributions (NICs) depending on profits. No NICs are due below £6,725 profit; 6% applies between £12,570 and £50,270, and 2% applies above £50,270.

Directors of limited companies instead pay Class 1 NICs salaries via PAYE. Dividends are taxed separately at lower rates.

What about import duties and customs taxes?

If you import stock from overseas, such as from suppliers in China or the United States, import VAT and customs duties apply. Rates depend on the product category and country of origin.

To stay compliant, classify products correctly using UK Tariff Codes, keep import and freight documentation, and work with customs brokers for complex shipments. We often assist clients with customs valuation reviews and reclaiming VAT paid on imports through their VAT returns.

What mistakes do Amazon sellers often make?

Why timely compliance matters for Amazon businesses

We help clients stay ahead of these regulations, keeping their businesses safe from penalties and maintaining smooth relationships with both Amazon and HMRC.
