Selling on eBay, Vinted, Etsy or TikTok Shop?
If you made more than £1,000 in gross sales from trading between 6 April 2025 and 5 April 2026, HMRC needs to hear from you by 5 October 2026.
Gross means before fees, postage and the cost of your stock, so plenty of sellers are over the line without realising it. Clearing out your own wardrobe is different; that is not trading and is not taxed.
We have written the whole thing up: who is caught, how the £1,000 trading allowance works, how to register, and what to do if the date has already gone.
