Hi, I am selling personal items which is not a business, just a house clearance on ebay - and there are more than 30 items for a value of more than £1000, but less than £2000. Currently i am less than 30 items and £1000, but ebay says it will contact HMRC when it gets to either, but when i do the checker, it says i have up to £6000 tax free, so don't need to do anything. Can you please advise it is still okay for me to sell and do nothing, or whether i should just wait until Aptil 1st to clear the rest? Kind Regards,
