eBay Seller Tax UK 2025/26: When You Owe HMRC
eBay is the most likely platform to land you on HMRC's radar simply because it's been around the longest, the audit trail is the most visible, and the typical seller crosses both reporting thresholds (30 transactions and £1,735) within a few months of decluttering. Here's a straight read of what eBay UK sellers actually owe in 2025/26.
The "am I trading?" test for eBay sellers
HMRC uses nine "badges of trade" to decide if you're a trader. The relevant ones for eBay sellers:
- Subject matter: are these items you'd normally use yourself, or stock?
- Frequency: occasional declutter or weekly listings?
- Length of ownership: did you own these for years or buy them last week?
- Modification: did you repair, restore, or repackage to add value?
- Profit motive: did you acquire intending to sell at a profit?
You don't need to tick all five. A pattern of buying car boot stock and reselling it on eBay clearly is trading. Selling 30 of your old DVDs over six months clearly isn't.
If you're trading on eBay
The mechanics are identical to other platforms:
- Gross sales under £1,000 in a tax year → no tax, no Self Assessment.
- Over £1,000 → choose between the £1,000 trading allowance or claiming actual expenses (PayPal/eBay fees, postage, materials, subscription to an inventory tool, mileage to drop-off).
- You'll owe income tax on net profit (20%, 40%, or 45% depending on your band) plus Class 4 NI at 6% / 2% if profit exceeds £12,570.
Use the calculator above with your gross eBay sales (before fees) and your other income to see the actual numbers.
eBay's reporting to HMRC: what you should know
Under platform operator rules, eBay reports UK seller data to HMRC by 31 January following each calendar year, covering anyone who made 30+ sales or €2,000+ in that year. The data includes your name, address, taxpayer reference (where known), bank details, total consideration paid, and number of transactions.
This is data sharing, not enforcement. HMRC then decides who to write to.
Common eBay scenarios and what they owe
| Situation | Tax owed (typical) |
|---|---|
| Decluttered own loft, sold £1,800 of personal items | £0, not trading |
| Bought wholesale phone cases, sold £2,500 gross, basic rate taxpayer | ~£300 + NI |
| Restored vintage furniture, £8,000 gross, £2,500 expenses, basic rate | ~£1,100 + NI |
| Resells trainers as side hustle, £15,000 gross, £6,000 expenses, higher rate | ~£3,600 + NI |
FAQs
I crossed 30 sales just selling my own stuff. Will HMRC come after me?
HMRC has the data but cross-checks against context. If your gross is reasonable for clearing out and you're not buying/making to sell, you have a defensible position. Keep notes (e.g. "cleared loft after house move") in case you receive a letter.
What expenses can I claim?
eBay/PayPal fees, postage, packaging, item cost, mileage at 45p/mile to the post office (first 10,000 miles), proportional internet/phone if used for the business, listing software subscriptions, accountant fees.
Do I owe VAT?
Only if your taxable turnover crosses £90,000 in a 12-month rolling period (2025/26 threshold). Most side hustlers are nowhere near. If you are, register before you cross.
I have a job and I'm a basic-rate taxpayer. Quick estimate?
Net profit on your eBay activity will mostly be taxed at 20% income tax + 6% Class 4 NI, so roughly 26% of profit. £2,000 net profit ≈ £520 tax & NI.
