eCommerce is a central driver of modern trade, and Value Added Tax (VAT) remains one of the biggest concerns for online sellers. Many businesses benefit from growth opportunities online, but the tax implications can seem difficult to manage. This blog will outline VAT essentials for eCommerce businesses so you can keep your books accurate and fulfil your obligations for the 2025/26 tax year.
According to the Office for National Statistics (ONS), eCommerce accounted for more than a quarter of total retail sales in the UK in 2024, and that share is likely to keep rising. If you sell products or digital services online, you should know the main factors that affect VAT registration, record-keeping, and cross-border transactions.
Below, we explain how the VAT registration threshold works, why it’s important for eCommerce, and the best ways to maintain compliance. We work extensively with eCommerce clients, and our team has developed a clear understanding of how online selling intersects with VAT. We will also highlight a few links to official UK sources – so you can find the government’s official guidance – and show where to find further support on our own website.
Understanding VAT for eCommerce
VAT is a consumption tax levied on the sale of most goods and services in the UK. For online sellers, it applies at various stages of the transaction process, depending on the nature of goods or services and where your buyers are based. The standard VAT rate in the UK is 20%, although certain goods and services qualify for reduced or zero rates.
When you sell online, you need to consider how VAT will apply to different products. For instance, digital eBooks that buyers download can be zero-rated if they meet the criteria for printed publications. Alternatively, if you sell physical books alongside digital products, you could end up dealing with different rates. The rates often stay the same each year, but it is important to check any updates from HMRC for the 2025/26 tax year.
If you choose to register for VAT voluntarily (before you are required by law), you can reclaim input VAT on business-related purchases. But you then need to charge VAT on your sales, which may affect your pricing strategy. Many online merchants keep an eye on their turnover to see whether they are close to the registration threshold.
VAT essentials for eCommerce businesses: Registration thresholds and obligations
One of the main VAT essentials for eCommerce businesses is understanding the UK’s registration threshold. For the 2025/26 tax year, the threshold is £90,000. You must register for VAT if your taxable turnover in any 12-month period exceeds this amount. Alternatively, if you know you will surpass the threshold in a short timeframe, you must register even before you reach it.
The registration process is straightforward through the government portal. You can find instructions on the official HMRC VAT page. Once registered, you need to file returns and pay any VAT due. Most eCommerce sellers do this quarterly, although some opt for monthly or annual schedules depending on their cashflow and business model.
Your obligations include:
- Charging the correct rate of VAT on your goods or services
- Keeping accurate digital VAT records for at least six years
- Submitting VAT returns by the relevant deadlines
- Paying any VAT owed on time
If you fail to meet these requirements, HMRC can apply interest on late payments and penalties on overdue returns. Being organised with your records helps you avoid errors and reduce the risk of fines.
Digital sales and cross-border considerations
eCommerce often involves international customers, which can create extra layers of VAT considerations. If you sell to consumers in the EU, you may be affected by rules such as the One Stop Shop (OSS) system. Through OSS, you can report all your EU VAT in a single return, reducing paperwork. If you trade with non-EU countries, you need to check the import VAT and customs duties that apply when goods enter the UK.
For digital services like software subscriptions and online media, the place of supply rules can determine where VAT is charged. These rules can be complicated if your customers are abroad. In some cases, VAT is due in the country of consumption, not in the UK. You can read more about cross-border business registrations on the Companies House website, which also provides guidance on international trading and setting up foreign branches.
Many small online businesses start by selling domestically, but as soon as you attract overseas buyers, you must keep track of additional reporting obligations. Clear and up-to-date records will help you identify what you owe and avoid overpaying or underpaying.
Maintaining VAT compliance
Your eCommerce platform may offer tools to help with VAT calculations and record-keeping. Marketplace websites like Amazon and eBay provide VAT settings, while standalone eCommerce platforms let you install VAT plug-ins. These features automate calculations based on product categories and delivery countries. However, you are still responsible for ensuring the data is correct.
Most businesses submit their returns online through HMRC’s Making Tax Digital (MTD) system. This means you must use compatible software to maintain digital records of sales, purchases, and VAT owed. You can also authorise an agent, such as an accountant, to file returns on your behalf.
We encourage our clients to schedule time each week to review records and bank statements. This helps you spot any anomalies early, instead of discovering an error during the quarterly VAT filing period. Timely reviews also prevent cashflow surprises – where the amount you owe is larger than expected – because you can see how much VAT is piling up.
Best practices for record-keeping
Staying VAT compliant is more straightforward when you adopt solid record-keeping habits. Here are a few points we highlight for eCommerce sellers:
- Separate business and personal finances: Use a dedicated account for all business transactions. Mixing personal costs with company purchases makes it harder to track VAT.
- Keep digital copies of invoices and receipts: Whether you store them in cloud-based solutions or local software, label them clearly with dates, reference numbers, and VAT amounts.
- Review supplier VAT charges: If you reclaim VAT on purchases, ensure your suppliers charge the correct rate. Mistakes on their side can affect your returns.
- Monitor your turnover: Set up alerts in your accounting software so you can see when you approach the £90,000 threshold. You might need to register sooner if sales surge.
- Check exchange rates for international sales: VAT amounts must be reported in sterling. Keep consistent records of exchange rates on specific invoice dates.
These steps make your filing process smoother and reduce your risk of incurring HMRC penalties. If you have any doubts about your record-keeping or if you need a second opinion, we can assist you. We do not rely on guesswork – we use precise calculations tailored to your online business.
