VAT for UK Online Shops: A Plain-English Overview

VAT is one of those topics online sellers tend to put off until it becomes urgent. Understanding the basics early saves a nasty surprise later, especially as your sales grow towards the registration threshold.

This guide gives a plain-English overview of VAT for UK online shops. It is general information, not tax advice — for your specific situation, always check with an accountant or HMRC, because the rules change and details matter.

When you have to register

In the UK, you must register for VAT once your taxable turnover passes the registration threshold over a rolling twelve-month period. Because the threshold figure can change, check the current level on the HMRC website rather than relying on an old number.

You can also register voluntarily below the threshold, which sometimes makes sense if you sell mostly to VAT-registered businesses or want to reclaim VAT on your costs. It is a judgement call worth discussing with an accountant.

Charging and showing VAT

Once registered, you charge VAT on most goods at the standard rate, though some items are reduced-rated or zero-rated. You then pay the VAT you collect to HMRC, less the VAT you have paid on your own business purchases.

For consumer-facing shops, prices shown should generally include VAT, so the displayed price is what the customer pays. Business-focused shops sometimes show prices excluding VAT. Get your shop set up to handle this correctly from the start.

Selling across borders and digital goods

Selling to customers in other countries, or selling digital products, can bring extra VAT considerations based on where the customer is. These rules are more involved and have changed in recent years, so they deserve proper advice if they apply to you.

Keep clean records of sales and the VAT involved from day one. Good bookkeeping makes VAT returns far less painful and means you are ready the moment you need to register, rather than scrambling after the fact.
