• If you are selling unwanted personal possessions such as old toys or clothes, this would not be classed as trading or miscellaneous income, and there is usually no tax to pay. In some circumstances there may be capital gains tax when selling valuable items such as jewellery, this is covered in our flowchart.

Do I have to share information with HMRC?

From January 2024, new UK digital sales reporting rules require digital platforms like eBay to share information with them. However, this reporting doesn’t change your tax obligations.

On eBay, this should only affect newly registered accounts in 2024, which will extend to all accounts in 2025.

eBay will only report if you pass certain yearly sales thresholds:

• If your total sales on eBay exceed €2000, or roughly £1740, after fees.

• If you complete 30 or more sales transactions on eBay.

In general, selling personal items is not taxed if they’re below £6,000 and you’re not selling as part of a business.
