VAT registration can enable the e-commerce business to claim VAT back on the stock, marketing and software. However, if the business is small in size and serves consumers mainly, then the VAT on sales can be higher than the VAT recovery due to increased prices or reduced margins. When assessing Ecommerce VAT obligations, the decision should be based on a forecast rather than turnover alone.
The right decision depends on customer type, product VAT rate, recoverable costs, pricing power and growth plans. It should be based on a forecast rather than turnover alone.
When is VAT registration compulsory?
A UK business must normally register when its Ecommerce VAT Registration Threshold is exceeded, which currently occurs when VAT taxable turnover exceeds £90,000 over any rolling 12 month period, or when it expects taxable turnover to exceed £90,000 within the next 30 days. A business below the threshold may register voluntarily.
Taxable turnover includes standard rated, reduced rated and zero rated sales, but not exempt or outside scope income. Overseas businesses making taxable UK supplies can face different rules and may not receive the £90,000 threshold.
What voluntary registration changes
Once registered, an ecommerce seller must:
- Charge the correct VAT rate on taxable sales
- Issue valid VAT invoices where required
- Record output VAT on sales and eligible input VAT on costs
- Maintain digital VAT records and submit returns through compatible software
- Pay HMRC the difference between output VAT and recoverable input VAT
Most goods and services carry 20% VAT, although some products, including books and children’s clothing, are zero rated. Product classification matters because a wrong rate can create assessments, interest and penalties.
Benefits for ecommerce sellers
Recovering input VAT
Registration can allow recovery of VAT on eligible stock, packaging, fulfilment, marketplace fees, website costs, advertising and accountancy services. Recovery requires the cost to support taxable business activity and suitable evidence, usually a valid Ecommerce VAT invoice.
VAT may also be reclaimed on qualifying purchases made before registration. HMRC generally allows claims for goods bought within four years if they are still held or incorporated into goods still held, and for services received within six months.
Supporting growth
Early registration can prevent a sudden pricing change when turnover reaches the compulsory threshold. It can also suit sellers expecting rapid growth or large setup costs because systems, invoices and product tax codes can be configured before sales volumes increase.
Helping B2B and zero rated sellers
Ecommerce VAT registered business customers can normally recover VAT subject to their own position, so VAT may have less effect on demand. Sellers of zero rated goods charge 0% while potentially recovering VAT on eligible costs, which can make voluntary registration particularly attractive.
Main disadvantages
Pressure on consumer prices
Consumers cannot reclaim VAT. A seller of standard rated goods must either raise the final price, absorb some or all of the VAT, or combine both approaches. This is often the deciding factor in competitive marketplaces.
Lower margins
Keeping the same Ecommerce VAT inclusive price means one sixth of a standard rated selling price becomes output VAT. Input VAT recovery offsets part of this cost, but not always enough to protect the existing margin.
More administration
VAT registration brings digital record keeping, VAT returns, tax point rules, reconciliations and evidence requirements. Ecommerce businesses must accurately reconcile website sales, marketplace settlements, refunds, fees, stock purchases, imports and multiple payment providers. VAT records usually need to be retained for at least six years.
Less flexibility
Voluntary registration is not necessarily easy to reverse. HMRC states that a voluntarily registered business generally remains registered for at least two calendar years unless its entitlement to registration has ceased. Businesses expecting only a temporary benefit should consider this before applying.
VAT margin example
This simplified example shows how to calculate VAT and assess the effect of registration on profit margins for an ecommerce seller.
Assume a seller supplies a standard rated product directly to consumers and keeps its retail price at £60.
| Item | Before registration | After registration |
| Customer price | £60 | £60 |
| Net sales income | £60 | £50 |
| Stock including £4 VAT | £24 | £20 |
| Fees and advertising including £2 VAT | £12 | £10 |
| Profit before other costs | £24 | £20 |
The registered seller collects £10 of output VAT and recovers £6 of input VAT. Keeping the price unchanged therefore sends £4 to HMRC and reduces the illustrated profit from £24 to £20.
If the price rises to £72, the net sales value remains £60 and profit increases to £30 because the input VAT becomes recoverable. The commercial risk is whether customers accept the £12 price rise. The example is simplified and excludes mixed VAT rates, imports, returns and non recoverable VAT.
When registration may suit
Voluntary registration is more likely to work where:
- Customers are mainly VAT registered businesses
- Products are zero rated or reduced rated
- The business buys substantial VAT bearing stock and services
- Major launch, equipment or marketing costs are planned
- Turnover is likely to cross £90,000 soon
- The seller has enough pricing power to pass VAT to customers
When waiting may suit
Remaining unregistered may be more attractive where:
- Sales are mainly to price sensitive consumers
- Competitors below the threshold offer similar products
- Input VAT is low or many suppliers are not VAT registered
- Margins cannot absorb output VAT
- Growth is uncertain and compliance costs would exceed recoverable VAT
A useful decision model compares annual recoverable input VAT with lost margin, expected sales impact, software costs and professional fees. Several forecasts should be tested, including keeping prices unchanged, passing VAT on fully and sharing the increase with customers.
VAT scheme considerations
The Flat Rate Scheme is not automatically cheaper. Eligible businesses with taxable turnover of £150,000 or less pay a sector percentage on VAT inclusive turnover but usually cannot recover purchase VAT, except on certain capital assets costing more than £2,000. Standard VAT accounting may therefore be more suitable for stock heavy sellers.
Cash Accounting can help cash flow by linking output VAT to customer receipts and input VAT recovery to supplier payments. It is generally available where expected taxable turnover is no more than £1.35 million, subject to conditions.
How UK ecommerce accountants help
UK online shopping accountants can use actual product margins, customer segments, market place charges, stock purchases and marketing expenses to quantify the financial impact of registration. This group can look into the rate of VAT, find out any eligible input VAT from historical transactions, establish the date of registration and set up accounting software. Further support could include VAT return preparation, import VAT, international sales and growth projections, thus enabling the company to claim valid VAT without harming the pricing and creating any compliance issues.
FAQs
Can an ecommerce business register before making sales?
Yes. HMRC may allow registration where there is a genuine intention to make taxable supplies, although the applicant may need to provide evidence of planned trading.
Can VAT be reclaimed on stock bought before registration?
Potentially. Goods must normally have been purchased within four years, remain on hand or be contained in goods still held, and relate to the registered taxable business.
Should an Amazon or Shopify seller register voluntarily?
The platform does not decide the answer. Registration is more attractive when recoverable VAT and growth benefits exceed the effect of output VAT, pricing pressure and compliance costs.
