His Majesty's Revenue and Customs (HMRC) took in reports covering 3,988,892 seller accounts during 2025, up 272% on the 1,466,171 it logged a year earlier, according to a Freedom of Information response obtained by the accountancy firm Binder Dijker Otte (BDO). The sales behind those accounts came to almost £55B, more than double the £25.5B logged for 2024.
Two caveats sit on those totals before anyone reads a crackdown into them. HMRC says the figures mix individual sellers with companies, partnerships, trusts, and charities, so the count is not four million people clearing out their lofts. And a report landing at HMRC is not a tax bill or a suspicion of one.
