Hi @Steve Browning,
I recently heard Ebay are reporting sales(presumably cumulative) over a certain amount to HMRC in case there are tax implications i.e they are assuming you are a business seller. I buy and sell a lot of musical gear - its a hobby and I usually make a loss on the sales - so if I sell gear on ebay for say £10,000 ( which actually cost me £12,000) how would that work tax wise or is it irrelevant or would need evidencing etc.
