| Situation | Tax? |
|---|---|
| Selling your own unwanted items | Usually no |
| Trading income up to £1,000 | No (trading allowance) |
| Trading income over £1,000 | Yes, tax return needed |
| Platform reporting | 30+ sales or about £1,700 a year |
In short: clearing out your own belongings is not trading. Buying or making items to sell for profit is. If your trading income is over £1,000, you need to register for Self Assessment.
A seller has £8,000 of sales and £3,000 of costs, plus a £30,000 salary. Profit is £5,000, taxed at 20%, so tax is about £1,000.
Since 2024, digital platforms report sellers with 30 or more sales, or around £1,700 of sales, to HMRC. Our side hustle tax returns service files your return, and our late tax returns team helps if earlier years were missed. More on our tax calculators page.
