Question 1

Is selling used socks legal in the UK?

Accepted Answer

Yes. Selling used clothing between consenting adults is legal in the UK. There is no specific law that bans the sale of worn socks, underwear or activewear provided both parties are 18+ and the transaction is not fraudulent.

Question 2

Do I have to pay tax on used-sock earnings?

Accepted Answer

Yes if your gross income across all self-employment exceeds the £1,000 HMRC trading allowance in a tax year. Above that, register for Self Assessment and declare the income. Below £1,000 you generally have nothing to file.

Question 3

Does HMRC know about my sales?

Accepted Answer

From 2024, UK marketplaces report seller data to HMRC under the DAC7-equivalent rules once you pass 30 sales or £1,700 in a year. Assume all payouts are visible and declare accordingly.

Question 4

Do I need to register a business?

Accepted Answer

Not to start. You can trade as a sole trader once you register for Self Assessment. Limited-company status only makes sense above roughly £30,000 profit — an accountant will confirm the threshold for your case.

Question 5

Can I be prosecuted for selling worn socks?

Accepted Answer

No. The transaction itself is lawful. Prosecution risk only arises from fraud (paid item never sent), tax evasion (not declaring), or selling to a minor (never accept an under-18 buyer).
