Yes, eBay reports sellers to HMRC. It has done since the rules took effect in January 2024, with the first reports filed in January 2025. And no, that almost certainly does not mean you owe tax, because reporting and owing are governed by two different rulebooks, and the panic industry that grew up around “the eBay tax” has done its best to blur them.

Here are both rulebooks, short version first: selling your own old stuff is not taxable, trading is, and the £1,000 line only matters for the second group.

What eBay actually reports, and when

Under the digital platform reporting rules, eBay collects and passes seller details to HMRC once you cross either threshold in a calendar year: 30 or more sales, or roughly €2,000, about £1,700, in proceeds. Below both, your activity is not reported at all. Above either, eBay files your details and totals to HMRC by the following January, and you will have been asked for your National Insurance number along the way.

Note what the report contains: totals. Not whether you were clearing the loft or running a business. That judgement, the one that decides everything, is made by the tax rules, and HMRC letters prompted by platform data still have to be answered with those rules, not with fear.

When selling is not taxable at all

Selling personal possessions for less than you paid produces no income and no gain. The volume does not matter. Someone clearing twenty years of accumulated life through three hundred listings owes nothing, because disposing of your own belongings at a loss is not a source of income, per HMRC’s own online income guidance. The only edge case for personal items is capital gains on a single item sold for over £6,000, the chattels rule, which catches jewellery, paintings and watches, and pointedly not your old sofa.

When it becomes taxable

Buying to resell, or making things to sell, is trading, and trading has thresholds. The first £1,000 of gross trading income per tax year is covered by the trading allowance, nothing to report. Beyond that, you register for Self Assessment, by 5 October after the tax year ends, and report the income with either the allowance or your actual costs deducted.

The honest test is intent and pattern. Sourcing stock at car boots for resale, buying wholesale, flipping retail arbitrage finds, that is trading from the first item. Selling the pram your kids outgrew is not, and never becomes it through repetition. The grey zone in between, the collector thinning a collection, the hobbyist selling occasional makes, is where the badges of trade do the deciding, and where keeping your own simple records converts arguments into answers.

If the letter has already arrived

HMRC has been writing to sellers whose platform data suggests undeclared trading. The letter is a prompt, the same one-to-many format as the other letters we have covered, and the response depends entirely on which rulebook you are actually in. Genuine personal selling gets explained, with dates and context, and closes. Genuine trading gets disclosed, and disclosed beats discovered on every line of the penalty table, the mechanics we set out in the disclosure guide.
