At Clark Jamison, we provide e-commerce tax advice to help online businesses remain compliant, minimise risk, and make confident financial decisions.
Running an e-commerce business brings tax challenges that don’t exist in traditional retail. VAT rules can change depending on where your customers are based, how you sell, and which platforms you use. Mistakes can quickly lead to penalties, unexpected liabilities or compliance issues.
We provide clear, practical e-commerce tax advice to UK online sellers, helping businesses stay compliant, reduce risk and make informed decisions as they grow.

E-commerce businesses we advise
Our e-commerce tax advice is designed for a wide range of online businesses, including:
- UK-based e-commerce businesses selling physical or digital products
- Sellers using platforms such as Shopify, WooCommerce, Amazon, eBay or Etsy
- Businesses approaching or exceeding VAT thresholds
- Online retailers selling to EU or international customers
- Subscription-based or digital service providers with VAT obligations
As online operations grow, many businesses also require broader business tax advice to ensure to overall tax position remains efficient and compliant.
E-commerce VAT and tax considerations
E-commerce businesses often face more complex tax obligations than traditional retailers. Selling online can trigger VAT, reporting and compliance requirements across multiple jurisdictions, even if your business is run solely from the UK.
Your tax position will depend on where your customers are located, the nature of your products, the platforms you use, and how quickly your turnover is growing.
Is VAT different for online sales?
VAT rules for online sellers vary depending on customer location and the type of goods or services sold. Domestic sales, international transactions and marketplace sales can all attract different VAT treatments.
Many clients seek specialist VAT consultancy and compliance support after discovering errors in how VAT has been applied to online sales and potentially reclaiming overpaid VAT.
Do I need to register VAT if I sell internationally?
In many cases, yes. Selling to customers outside the UK can create VAT registration and reporting obligations in other jurisdictions. Schemes such as OSS or IOSS may apply, but they are not suitable for every business.
International sellers often require tailored international tax advice to understand where they need to register and remain compliant.
Common VAT and compliance issues for e-commerce tax businesses
It is most beneficial to address the tax position in advance of any change in circumstances, though we can assist if the following issues have already arisen:
- Missing VAT registration deadlines following rapid growth
- Assuming marketplaces handle all tax obligations
- Applying incorrect VAT treatment to EU or international sales
- Poor reconciliation between marketplace reports and accounting records
- Expanding internationally without structured tax planning
Early tax planning can significantly reduce the risk of these issues.

Example 2
An Amazon seller identifies discrepancies between marketplace VAT reports and their bookkeeping records.
Example 3
A digital product business requires guidance on VAT treatment for EU or worldwide customers following expansion overseas and regulatory changes.
Each scenario requires advice tailored to how and where the business operates.
