Re: Airbnb, ebay, vinted and other apps to share more information with HMRC
If your selling things for less then you bought them your ok from what I read. The question though is if you sell something for a loss, can you write that off against your tax bill if you do a self assessment? Theoretically if they tax you for a profit you should be able to claim for a loss as you would if you were involved in any other trade.
