When you sell something at a profit, HMRC has to decide whether you are trading or just disposing of an asset. The badges of trade are the nine signposts it uses to make that call.
If you buy a job lot of vintage watches, do them up and sell them on at a profit, are you a trader or just someone who got lucky on a sale? The answer decides how you are taxed, and it is not always obvious. HMRC does not have a single rule for this. Instead it leans on the badges of trade, a checklist distilled from decades of court cases, to judge whether what you are doing is a trade or merely the disposal of an asset.
The badges exist to answer one question with real money attached: is this profit income or capital? The two are taxed very differently.
If you are trading, your profit is income. It is taxed at 20%, 40% or 45% depending on your band, and it also attracts Class 4 National Insurance. You normally have to register as self-employed and file a Self Assessment return. If instead you simply sold an asset that happened to rise in value, the profit usually falls under Capital Gains Tax, which has a separate £3,000 annual exempt amount and lower rates of 18% and 24%. The same £20,000 profit can therefore land you with a substantially different bill depending on which category it sits in.
The courts have identified nine factors. HMRC weighs them collectively, no single one is conclusive.
| Badge | What HMRC looks at |
|---|---|
| Profit-seeking motive | Did you intend to make a profit when you acquired the asset? |
| Number of transactions | Repeated, systematic deals point to trading; a single sale less so |
| Nature of the asset | Was it something normally bought to use or enjoy, or to resell? |
| Connection to existing trade | Is the deal linked to a trade you already carry on? |
| Changes to the asset | Did you process, repair or repackage it to make it more saleable? |
| Way the sale was carried out | Was it marketed and sold in a businesslike, commercial way? |
| Source of finance | Did you borrow to buy, expecting the sale to repay the loan? |
| Interval between buy and sell | A quick turnaround suggests trading; long-held assets less so |
| Method of acquisition | Bought deliberately to resell, or inherited/received as a gift? |
The more badges that point towards commerce, the stronger HMRC's case that you are trading. A one-off sale of an inherited painting ticks almost none of them; buying 200 pairs of trainers to flip on a resale app ticks most.
Take Priya, who in 2025/26 buys 50 broken laptops at auction for £5,000, repairs them over three months, advertises them online and sells them for £15,000 in total. Her costs (parts, listing fees) come to £2,000.
| Step | Amount |
|---|---|
| Sale proceeds | £15,000 |
| Less purchase cost | £5,000 |
| Less repair/selling costs | £2,000 |
| Profit | £8,000 |
Several badges fire here: a clear profit motive, multiple transactions, work done to make the goods saleable, a businesslike sale, and a short interval. HMRC would treat Priya as trading. Her £8,000 is income, so after using her £1,000 Trading Allowance (if she had not deducted actual expenses instead), she pays Income Tax and Class 4 National Insurance on the profit through Self Assessment. Had she simply sold one inherited laptop for a £200 gain, no trade would arise. Our blog covers how online sellers and side-hustlers should handle this.
Not every small profit creates a tax headache. The £1,000 Trading Allowance means casual income up to £1,000 a year is tax-free and needs no return at all. Sell a few items occasionally and you are comfortably inside it. The badges of trade really start to matter once your activity is regular, deliberate and profit-driven enough to push past that threshold, at which point HMRC expects you to register and declare.
The badges of trade are not a tick-box test but a balancing exercise. Buy to use and later sell, and it is capital; buy to sell, repeatedly and for profit, and you are trading.
