You’re making sales on Amazon, money is landing in your account, and you’re wondering whether hiring an accountant is a smart investment or an unnecessary cost.
The honest answer is: it depends on where your business is right now. Some sellers can manage perfectly well on their own in the early days. Others need accountants for Amazon sellers much sooner than they expect, usually because of VAT, multichannel selling or a fast growth rate.
This guide helps you decide. You’ll see what the law actually requires, when DIY is realistic, the moments when hiring pays off, and what it costs to get it wrong.

Is It a Legal Requirement to Hire an Accountant?
No. In the UK, there is no law that says you must use an accountant to sell on Amazon, eBay, Etsy or Shopify.
But you do have legal responsibilities, whether you hire help or not:
- Register as self-employed with HMRC if your trading income is above the £1,000 trading allowance, and file a Self Assessment tax return.
- Keep records of sales, costs and stock, usually for at least five years after the 31 January filing deadline.
- Register for VAT once you pass the threshold (more on this below).
- Pay the right tax on time, including payments on account if your bill is large enough.
HMRC will not accept “I didn’t know” as an excuse. So the real question isn’t “am I forced to hire an accountant?” It’s “can I meet these duties accurately on my own?”
When You Can Probably Manage Without an Accountant
DIY accounting can work if most of these are true:
- You’re a sole trader with a small side business
- Your turnover is well below the VAT threshold
- You sell in the UK only, mainly on one platform
- You carry little or no stock
- You’re comfortable with spreadsheets or basic software and keep records every month
- Your income is simple, with no employees and no other complicated sources
Example: Hannah sells handmade prints on Etsy for about £12,000 a year. Her costs are materials, postage and fees. She tracks everything in a spreadsheet, files her own tax return and has no VAT issues. For her, an accountant isn’t essential yet, though a one-off check of her first return might give her peace of mind.
Even then, keep clean records from day one. It’s far easier than rebuilding a year of data later.
When You Probably Need Accountants for Amazon Sellers
The picture changes when complexity or risk goes up. These are the main triggers.
1. You’re close to the VAT threshold
You must register for VAT if your taxable turnover exceeds £90,000 in any rolling 12-month period, or you expect to go over it in the next 30 days. The deregistration threshold is £88,000. Both are unchanged for 2026/27.
Remember:
- It’s about turnover, not profit
- It’s rolling, so you can cross it at any point in the year
- Every channel counts, so Amazon, eBay, Etsy and Shopify sales are added together
Example: Dan sells pet products. He makes £38,000 on Amazon, £31,000 on eBay and £25,000 on his Shopify store. No single channel looks risky, but his total is £94,000. He needed to register already, and HMRC can charge VAT back to the date he should have, even on sales where he never added VAT to the price.
Late registration can mean back-dated VAT, interest and penalties, which is why many sellers get advice at around £70,000 to £80,000.
2. You can’t explain your payouts
Amazon pays you net of fees, refunds, advertising and storage charges. If you can’t reconcile a payout back to the sales behind it, your profit figure is a guess, and so is your tax bill.
Specialist accountants usually connect Amazon to software like Xero or QuickBooks using tools such as A2X or Link My Books, so each payout is split into sales, fees and refunds automatically.
3. You hold stock or sell across borders
Inventory, FBA stock sitting in warehouses, imports and overseas customers all add rules. Import VAT, customs duty and possible VAT registration in other countries can apply depending on where your stock is and where you sell. Mistakes here tend to be expensive.
4. You’re deciding between sole trader and limited company
A limited company can be more tax-efficient once profits are higher, but it brings extra admin, such as annual accounts, corporation tax returns and director responsibilities. The right answer depends on your profit, goals and how much you take out personally. Getting this wrong in either direction costs money, and switching later has its own tax and practical consequences.
5. Making Tax Digital applies to you
If you’re VAT-registered, you must keep digital records and file VAT returns through MTD-compatible software. Making Tax Digital for Income Tax is also being phased in, starting in April 2026 for sole traders and landlords with qualifying income over £50,000, with lower thresholds planned for later years.
Quarterly updates are manageable if your records are tidy. If they aren’t, they quickly become a burden.
What About Marketplace VAT Rules?
Many sellers assume Amazon “handles VAT”. For UK-based sellers, that’s not the case.
Marketplaces are responsible for VAT on certain sales by overseas sellers to UK customers. Overseas sellers with no UK establishment have no threshold and must register from their first taxable UK sale. As a UK seller, you remain responsible for your own VAT registration, charging and returns.
This may change. HMRC and HM Treasury ran a consultation, which closed on 18 August 2026, on extending marketplace VAT liability to sales by UK sellers. The lead option would apply a £90,000 threshold per platform, alongside the normal registration rules. Nothing is confirmed, so it’s worth keeping an eye on, and an accountant who follows these changes can tell you what applies to you.
DIY, Software or Accountant? A Quick Comparison
| Option | Best for | Main risk |
| Spreadsheet only | Very small, simple sellers | Errors, missed costs, no MTD compliance for VAT |
| Accounting software yourself | Confident sellers below the VAT threshold | Misclassifying fees, VAT mistakes, no strategic advice |
| Accountant for tax returns only | Simple businesses wanting a safety net | Problems found too late, after the year ends |
| Specialist accountants for Amazon sellers | VAT-registered, growing or multichannel sellers | Cost, if you pick a firm without ecommerce experience |
A hybrid approach is common: you keep the books day to day using software, and an accountant reviews them regularly and handles VAT, tax planning and filings.
What Does It Cost, and Is It Worth It?
Fees vary by turnover, complexity and services, so quotes can differ widely. Ask for a fixed monthly price and a clear list of what’s included, such as bookkeeping, VAT returns, tax returns and advice.
To judge value, compare the fee with what mistakes can cost:
- Back-dated VAT you never collected from customers
- Penalties and interest for late filing or late payment
- Overpaid tax from missed expenses or the wrong structure
- Hours of your own time spent on admin instead of sourcing and selling
A good accountant often saves more than they cost, but only if they understand ecommerce. A generalist unfamiliar with Amazon settlement reports can create as many problems as they solve.
How to Choose the Right Accountants for Amazon Sellers
Look for:
- Proven experience with FBA and FBM sellers
- Familiarity with Xero or QuickBooks and Amazon reconciliation tools
- Knowledge of UK VAT, import VAT and selling to the EU
- MTD-compliant filing
- Clear, fixed pricing
- Proactive advice during the year, not just year-end paperwork
- Reviews or case studies from other online sellers
Checklist: Should You Hire an Accountant?
Tick what applies to you:
- My rolling 12-month turnover is above £70,000
- I sell on two or more platforms
- I can’t reconcile my Amazon payouts to my sales
- I hold stock, use FBA or import goods
- I sell to customers outside the UK
- I’m unsure whether to be a sole trader or limited company
- I’m VAT-registered or about to be
- I haven’t started preparing for MTD
- HMRC has contacted me, or I’m behind on filings
0 to 1 ticks: you can probably manage alone, with a yearly check. 2 to 4 ticks: a consultation is a sensible next step. 5 or more: hire a specialist now.

Frequently Asked Questions
Do I need to tell HMRC I’m selling on Amazon?
If your trading income is above £1,000 in a tax year, you generally need to register as self-employed and file a Self Assessment return. Marketplaces also report seller income to HMRC, so it’s wise to declare everything correctly.
At what turnover should I hire accountants for Amazon sellers?
There’s no fixed figure. Many sellers get help once they approach the £90,000 VAT threshold or start selling across several channels. Earlier advice on structure and records can save money.
Can I use Amazon’s reports instead of an accountant?
Amazon’s reports are a useful data source, but they aren’t accounts. They need to be reconciled, categorised and matched to your costs and stock before they can support a tax or VAT return.
Does Amazon pay VAT for UK sellers?
No. As a UK-based seller you must register, charge VAT where required, file returns and pay HMRC. Amazon may calculate VAT or account for it on some overseas sellers’ sales, but that doesn’t remove your own obligations.
Can an accountant help if I’m already behind?
Yes. They can assess the position, contact HMRC on your behalf and help you put things right. Acting sooner usually limits penalties and interest.
Conclusion: Make the Decision Before the Problem Makes It for You
You don’t need an accountant to start selling on Amazon, but you do need accurate records, correct VAT and a tax plan that grows with you. If you’re nearing the VAT threshold, selling on several platforms or struggling to understand your numbers, the right accountants for Amazon sellers are likely to pay for themselves.
