An ecommerce accountant is a qualified accountant who specialises in managing the finances of online retail businesses. Unlike a general accountant, they understand the challenges online sellers face, including multi-channel sales, marketplace fees, international VAT, stock management, and payment reconciliations.
In the UK, ecommerce businesses have specific tax and accounting responsibilities that differ from traditional high street retailers. These include:
- Registering for and filing VAT returns, including Making Tax Digital (MTD) compliance
- Reconciling income from multiple platforms (Amazon, Shopify, eBay, Etsy)
- Accounting for marketplace fees, refunds, chargebacks, and currency conversions
- Managing stock and cost of goods sold (COGS) accurately
- Handling cross-border VAT if you sell into the EU, USA, or other international markets
- Filing Corporation Tax if you operate as a limited company, or Self Assessment if you're a sole trader
A specialist ecommerce accountant handles all of this for you. They keep your accounts accurate, file your returns on time, and make sure you pay only the tax you legally need to.
Why Ecommerce Businesses Need a Specialist Accountant
General accountants do a great job, but ecommerce finance works differently. Here is why a specialist ecommerce accountant makes a real difference to your business:
1. Reconciling Multi-Platform Revenue is a Challenge
Selling on Amazon, Shopify, eBay, and Etsy is great for growth until you need to reconcile all that income. Every platform has its own payment schedules, fee deductions, and reporting formats. It gets confusing quickly. Most general accountants struggle here. Our ecommerce accountants use smart tools like Xero and FreeAgent to automatically import every transaction and match everything up, so you always know exactly where you stand.
2. VAT Rules for Online Sellers Keep Changing
For UK ecommerce sellers, once you hit £90,000 turnover (the 2025/26 threshold), you must register for VAT and file quarterly returns under Making Tax Digital. Selling into the EU or the US? The compliance work multiplies fast. We take care of your UK VAT registration, MTD filings, and all those international VAT headaches for you, so you can get on with running your business.
3. Stock and COGS Can Wipe Out Your Profits
Inventory is at the heart of your business. If you don’t track your cost of goods sold (COGS) accurately, your profits, tax, and even HMRC audits can be affected. Get it wrong and you could end up paying too much or too little tax, risking HMRC scrutiny. Our team ensures your COGS, stock valuation, and profit margins are correct from the start, keeping you safe from any surprises.
4. Sole Trader or Limited Company? Making the Right Choice
Your business structure matters. If your profits are over £30,000–35,000, switching from sole trader to limited company could mean major tax savings, thanks to the mix of salary and dividends. We review your setup as part of onboarding and recommend what’s best for your numbers, not just what’s in the textbooks.
5. Marketplace Rules and Penalties are Always Changing
Amazon, Shopify, and HMRC all update their rules regularly. From Amazon's VAT requirements for UK sellers, Shopify's integration with HMRC's MTD service, to new reporting requirements for digital platforms under DAC7, our team keeps up with every change. You focus on selling we’ll handle the compliance.
Ecommerce Platforms We Support
We support UK online sellers across all major marketplaces and ecommerce platforms. Here’s how we help with each one:
Shopify Accountant UK
Shopify leads the UK ecommerce market, but it can be complex from an accounting point of view. Payments, third party processors, multi currency, and Shopify Markets can quickly become difficult to manage if your setup is not right from the start.
Our Shopify accountants connect your store to Xero accounting software or FreeAgent accounting software using A2X accounting integration or Shopify’s own integration. This means every sale, refund, fee, and payout is recorded automatically. We manage your VAT returns under Making Tax Digital, advise on the right business structure, and handle all your filings.
- Shopify + Xero integration set up and managed for you
- VAT registration and quarterly MTD-compliant Shopify VAT returns
- Multi-currency reconciliation for international Shopify stores
- Advice on Shopify business structure: sole trader vs limited company
Amazon FBA Accountant UK
Amazon FBA can be complex, even for experienced sellers. Amazon settlements include fulfilment fees, referral fees, advertising costs, and reimbursements, and you need to account for them correctly for tax.
Our Amazon FBA accountants understand Seller Central reports in detail. We reconcile your payouts, account for all FBA fees and storage costs, keep you compliant with VAT, including Amazon’s VAT calculation service, and make sure you claim every valid expense, from packaging to advertising and software.
- Amazon settlement reconciliation via A2X integrated with Xero
- FBA fee categorisation and COGS tracking
- Amazon VAT calculation service, compliance and filing
- Pan-European VAT advice if you sell across EU marketplaces
- Amazon FBA limited company setup and tax planning
eBay Accountant UK
eBay sellers, whether you are reselling or running a business, face their own challenges. Under DAC7 rules, eBay reports seller income to HMRC once you earn over £1,700 a year, so accurate record keeping is essential.
Our eBay accountants help you understand your tax position, register for Self Assessment, claim all allowable selling expenses, and file on time. If your eBay business grows, we also help you decide when moving to a limited company makes sense.
- Self Assessment filing for eBay sellers
- Guidance on the £1,700 DAC7 reporting threshold and what it means for your taxes
- eBay fee and postage expense claims
- Transition support from sole trader to limited company
Etsy Accountant UK
Etsy is a popular marketplace for UK creative sellers, handmade products, and digital downloads. As an Etsy seller, you need to understand how fees work, whether you need to register for VAT, and how to report your income correctly on your Self Assessment tax return to HMRC.
Our Etsy accountants support makers, designers, and digital creators across the UK. We connect your shop to your accounting software, reconcile listing fees, transaction fees, and Etsy Payments, and keep your accounts accurate whether you sell 10 items or 10,000 a year.
- Etsy income declaration on Self Assessment
- Etsy fee reconciliation and expense tracking
- VAT advice for Etsy sellers
- Digital product VAT rules for Etsy sellers selling in the EU
Our Ecommerce Accounting Services
Here's exactly what's included when you work with GoForma as your ecommerce accountant:
Ecommerce Bookkeeping
Accurate bookkeeping keeps your business on track and everything else relies on it. We connect your sales platforms, payment processors like PayPal, Stripe, Klarna, Square, and your business bank account directly to your accounting software. Each sale, refund, and fee is tracked, organised, and matched up automatically. You’ll always know where your money is, and HMRC gets the correct figures on time.
VAT for Ecommerce Sellers
VAT is one of the most complex areas for UK online sellers. We handle:
- VAT registration - we tell you when to register, help you choose the right VAT scheme (standard, flat rate, or cash accounting), and submit your application
- Quarterly VAT return preparation and submission, fully MTD-compliant
- Reverse charge VAT for digital services and cross-border B2B sales
- Import VAT accounting post-Brexit
- EU VAT including IOSS registration and management for sellers shipping to EU customers
- VAT deregistration when appropriate
Self Assessment Tax Returns for Online Sellers
If you’re a sole trader selling online, you must file a Self Assessment tax return by 31 January each year. We prepare your return, claim every allowable expense such as home office costs, software, internet, packaging, advertising, platform fees, and file it before the deadline. Avoid HMRC penalties with GoForma supporting you.
Limited Company Accounts and Corporation Tax
Running your business as a limited company? We prepare your annual accounts, file with Companies House, and complete your Corporation Tax return for HMRC. We’ll also advise you on the best combination of salary and dividends, so you keep more of your earnings and pay no more tax than necessary.
Payroll for Ecommerce Businesses
Paying yourself as a director or managing payroll for staff? We handle your monthly payroll, including PAYE submissions, payslips, and workplace pension enrolment if it’s needed. Everything is processed on time.
Business Structure Review: Sole Trader vs Limited Company
Unsure whether to remain a sole trader or switch to a limited company for your online business? We’ll provide a free, personalised review. We assess your revenue, expenses, and growth plans, then show you exactly how much you could save in tax in real pounds and pence, not just percentages.
Accounting Software Setup and Support
We set you up with Xero or FreeAgent, connect all your marketplaces and bank accounts, and guide you in using the software. You’ll have real-time visibility of your profit margins, cash flow, and tax liabilities, on any device.
VAT for Ecommerce Sellers
VAT causes more problems for UK ecommerce sellers than almost anything else. But with a specialist accountant on your team, you can avoid most of the hassle. Here’s what you really need to know.
When Do You Need to Register for VAT as an Online Seller?
For the 2025/26 tax year, you must register for VAT once your taxable turnover exceeds £90,000 in any rolling 12-month period. It doesn’t matter if you sell on Shopify, Amazon, eBay, Etsy, or your own site, this rule applies across the board.
Sometimes, it actually makes sense to consider consider voluntary before you hit that threshold. If you mostly sell to other VAT-registered businesses (B2B), or you have large VAT bills on your expenses that you want to reclaim, voluntary registration can be a smart move.
Our ecommerce accountants monitor your turnover and tell you exactly when it’s time to register, so you don’t get hit with unexpected penalties for missing the threshold.
Which VAT Scheme is Right for Ecommerce Sellers?
|
VAT Scheme
|
Best suited to
|
|
Standard Rate VAT
|
Most ecommerce businesses — charge 20% on sales, reclaim VAT on expenses
|
|
Flat Rate VAT
|
Lower-turnover businesses with few VAT-able expenses — you pay a fixed % of turnover
|
|
Cash Accounting VAT
|
Businesses with slower-paying customers — you account for VAT when cash is received
|
|
Annual Accounting VAT
|
Businesses wanting reduced admin — one return per year with advance payments
|
The right VAT scheme for your ecommerce business depends on your margins, turnover, and the nature of your customers. Our team advises you on the most tax-efficient option when you join.
Making Tax Digital (MTD) for Ecommerce Sellers
Every VAT-registered business in the UK now has to file VAT returns using Making Tax Digital. That means you need MTD-compatible accounting software that links directly to HMRC as manual submissions and the old online portal are no longer allowed.
We set you up with Xero or FreeAgent from day one, both fully MTD-compliant. Your VAT returns go straight from your software to HMRC without needing to enter data manually.
Selling to EU Customers
If your ecommerce business ships goods to EU customers, your VAT obligations changed significantly after Brexit. Here's what applies:
- For orders under £135 sent to EU consumers, you charge VAT at the rate of the destination country and pay it through IOSS (Import One Stop Shop). Or, just use a marketplace like Amazon or eBay who usually handle this for you.
- For orders over £135, the customer pays import VAT when their package arrives. This can hurt your conversion rates, so it’s worth considering tax-efficient EU fulfilment strategies.
- For B2B sales to EU VAT-registered businesses, you usually zero-rate the sale. The reverse charge applies on their end.
Our ecommerce accountants develop the best EU VAT strategy for your business and make sure you’re not missing out on any opportunities.
Making Tax Digital for Ecommerce Businesses
Making Tax Digital (MTD) is HMRC’s initiative to move all UK tax reporting to digital platforms. For ecommerce sellers, there are two rules you need to know now.
MTD for VAT (now mandatory for all VAT-registered businesses)
If you’re VAT-registered, you must use MTD-compatible software to keep digital records and submit your VAT returns. We use Xero and FreeAgent, both of which are HMRC-approved.
MTD for Income Tax Self Assessment (from April 2026)
From April 2026, if you’re a self-employed ecommerce seller or landlord making over £50,000, you need to file quarterly updates under MTD for Income Tax Self Assessment (MTD for ITSA). From April 2027, the threshold drops to £30,000.
Sole Trader vs Limited Company for Ecommerce
Should you run your ecommerce business as a sole trader, or should you form a limited company? It’s the question we get asked most by UK online sellers and we take it seriously, because choosing the right structure can save you thousands in tax every year.
|
Sole Trader
|
Limited Company
|
|
Simple to set up and run
|
More tax reporting responsibilities - annual accounts, Corporation Tax return
|
|
All profits taxed as income (20%–45%)
|
Tax-efficient salary + dividends structure
|
|
Class 2 + Class 4 National Insurance on profits
|
Lower NI if structured correctly
|
|
Personal liability for business debts
|
Limited liability, personal assets protected
|
|
Best for lower-profit, early-stage sellers
|
Better once profits exceed ~£30,000–35,000
|
|
No registration with Companies House
|
Must file accounts at Companies House (public)
|
Most UK ecommerce sellers reach a tipping point when their yearly profit goes over £30,000–£35,000. Above this level, operating as a limited company just makes sense as the tax savings from taking a low salary and the rest as dividends easily outweigh the extra admin costs.
At GoForma, we give every new ecommerce client a free review of their business structure where we actually work out your numbers and show you exactly how much tax you’ll save.

DAC7 - What UK Online Sellers Need to Know About Platform Reporting
From January 2024, HMRC introduced new rules under the EU’s Directive on Administrative Cooperation (DAC7). Digital platforms like Amazon, eBay, Etsy, Airbnb, and Fiverr now send your earnings directly to HMRC. If you make over £1,700 a year on any single platform, or have more than 30 transactions, the platform is legally required to report your details and earnings.
So HMRC already knows what you’ve earned even if you haven’t declared it. That’s why accurate Self Assessment and proper ecommerce tax compliance are more important than ever. If you’ve delayed declaring your online income and you’re concerned, don’t worry. Our team can help you sort things out with HMRC before they contact you.
