Selling on eBay has become increasingly common, whether you're clearing out unwanted items, selling collectables, or running a small business. As your eBay sales increase, you might wonder: do I need to pay tax on what I sell?

Here's what you need to know about tax and eBay sales, including the difference between occasional selling and trading, when tax may apply, and how HMRC and eBay now share data.

eBay Tax Rules: Do You Need to Pay Tax on eBay Income? | Taxwise Accountancy

Occasional Selling vs Trading

Occasional Selling

Usually No Tax Due

If you are only selling items from time to time, such as second-hand clothes, furniture, or gadgets, HMRC usually won't consider you to be trading, and no tax would be due.

Clearing out unwanted items occasionally

Trading

Tax May Be Due

However, if you are buying things with the intention of selling them, regularly reselling for a profit, or running a small online shop, HMRC may treat you as a business.

This can apply even if it's not your main source of income

Signs That You May Be Trading

Buying to Resell

You buy goods specifically to resell at a profit

Making to Sell

You make items to sell, such as crafts or personalised gifts

Regular Selling

You sell regularly and in a business-like way

Marketing Activity

You advertise your products or take custom orders

Selling Used Items at a Loss

If you are selling personal items for less than you originally paid for them, such as books, clothes, or tech, you will not usually have to pay tax.

Example:

You bought a mobile phone for £800 last year and now sell it for £400 on eBay.

Since there is no profit, no tax is due.

However: Even if the items are personal, selling regularly or in high volumes might still attract attention from HMRC.

Is There Such a Thing as an "eBay Tax"?

You may have heard the term "eBay tax" used online. Whilst it is not a formal HMRC term, it is often used to describe the tax that might be due on income from selling on eBay.

There is no separate eBay tax

But if you are trading, your income could be subject to income tax and possibly National Insurance, depending on your earnings and circumstances.

The Important Thing:

It's not the platform you use, but the nature of your selling activity. Whether you sell through eBay, Vinted, Etsy or Facebook Marketplace, the same tax rules apply.

HMRC and eBay Now Share Data

Increased Efforts to Identify Undeclared Income

HMRC has increased efforts to identify undeclared income from online selling.

Thanks to international data-sharing agreements, eBay and similar platforms are now required to pass seller information to tax authorities.

Information Shared Includes:

Seller names and contact details

Transaction numbers and values

Linked bank accounts

HMRC May Already Know About Your Activity

This means HMRC may already be aware of your activity, so it's important to remain compliant and declare all taxable income.

Do I Need to Register With HMRC?

£1K

If your total trading income (from eBay and other platforms) exceeds £1,000 in a tax year, you usually need to:

Register for Self Assessment

Sign up with HMRC as self-employed

Submit a Tax Return

File by 31 January each year

Even if you think you won't owe any tax, it's best to check. Registering voluntarily also shows you're acting in good faith with HMRC.
