As we all know, HMRC now wants a slice of your side earnings from sites like this. They think that some sellers are masquerading as private sellers instead of business sellers and are therefore trying to avoid paying tax. There has been a lot of misinformation surrounding this whole scenario regarding what you are allowed to earn in any one year. Apparently if you earn under £1,000 after deducting fees and commissions or taxes, it doesn't affect you, but if you earn above the £1,000 trading allowance, HMRC will want their slice. Even if you make no where near this in money but complete 30 sales, HMRC wants to know about this too, so either way they have you over a barrel. If you are selling unwanted possessions that have been lying around your home, such as the contents of a loft or garage, you will not need to pay tax. However, if you sell these items for more than you paid for them, you may have to pay capital gains tax, but only if you exceed £6,000. It seems HMRC is going after the small fish and ignoring the ones who do not pay any tax or hardly any, i.e., Amazon, Vodafone, and so on. What they can't get from them, they want from sellers on these platforms. Welcome to Tory Britain.
