Do you pay tax on eBay sales in the UK?

It depends on one thing: are you selling your own stuff, or buying to resell for profit? Here's how to tell which side of the line you're on — and what HMRC expects.

The quick answer: Selling your own unwanted items on eBay is generally not taxable. If you buy to resell for profit, you can earn £1,000 in sales tax-free per year — over that, you'll likely need to declare it to HMRC via Self Assessment.

Selling your own things vs trading

This is the whole question. eBay is full of both:

The £1,000 trading allowance

If you're trading, HMRC gives you a £1,000 Trading Allowance each tax year. Two things people always get wrong:

Under £1,000 of sales, you usually have nothing to report. Over it, you'll likely need to register for Self Assessment and pay tax on your profit (sales minus your costs and fees).

What about eBay reporting me to HMRC?

eBay, like other platforms, must report sellers who pass 30 items or about £1,700 a year. That's a data-sharing threshold — a heads-up to HMRC — not a tax bill. Whether you owe still depends on the £1,000 allowance and whether you're trading.

Don't forget your costs

If you are trading, you're taxed on profit, not sales. You can deduct what you paid for the item, postage, and eBay fees — or claim the flat £1,000 allowance instead, whichever leaves you paying less. Keeping a simple record as you go makes this painless:

Frequently asked

Do my eBay and Vinted sales count separately?

No — the £1,000 allowance is per person across all your selling, so add them together.

Are eBay fees and postage deductible?

Yes, if you're trading. You're taxed on profit, so item cost, postage and selling fees come off — or use the flat £1,000 allowance instead.

I'm just selling old stuff from my house. Tax?

Generally none — that's not trading. Keep a rough note of what you sold just in case.
