Key points
- Selling your own collection is treated differently from buying to resell.
- Regular buying and reselling for profit can amount to trading.
- Online marketplaces report seller data to HMRC under international rules.
- Keep records of what you paid, what you sold for, and the costs in between.
Clearing a collection versus trading
HMRC distinguishes between disposing of personal possessions and carrying on a trade. Someone selling cards they collected over years is in a different position from someone buying boxes weekly, breaking them and reselling the singles.
The tests HMRC applies look at intention at the time of purchase, frequency of transactions, whether items are modified or improved for sale, and how the activity is organised and financed. No single factor decides it.
If the activity is trading
Trading profits are subject to income tax and potentially National Insurance, reported through Self Assessment. Profit is income less allowable expenses, which for card sellers typically includes cost of stock, marketplace fees, postage, packing materials and grading costs.
There is a trading allowance that covers a small amount of gross trading income without a need to report it. Where income exceeds it, the position needs to be reported properly.
If the disposal is capital
Where cards are personal possessions rather than trading stock, disposals can fall under capital gains rules, with an annual exempt amount and specific rules for chattels. Sets and collections sold to the same buyer can be treated as a single disposal rather than many small ones.
Platform reporting
Under international digital platform reporting rules, online marketplaces collect and report seller information to HMRC where sellers exceed low thresholds of transactions or value in a year. Receiving a report does not by itself mean tax is due, but it does mean the activity is visible.
Records worth keeping
Good records make the position defensible and usually reduce the tax due, because expenses can only be claimed if they can be evidenced.
- Purchase date, source and price for every card or box
- Sale date, platform, gross price and fees
- Postage and packing costs
- Grading and authentication fees
- Bank and payment processor statements
Common questions
Is there a fixed amount you can sell before paying tax?
There are allowances, and the relevant one depends on whether the activity is trading or capital in nature. Because the thresholds and rates change, check the current figures on GOV.UK or with an accountant.
Do losses count?
In a trading context, allowable expenses and losses are part of the calculation. Records are what make that possible.
