Frequently Asked Questions

Do I pay tax on eBay sales in the UK?

If your total eBay sales income exceeds £1,000 per tax year (the Trading Allowance threshold), you must register for Self Assessment with HMRC and declare your income. The tax-free £1,000 Trading Allowance applies to the gross income, not profit.

What is the £1,000 Trading Allowance for eBay sellers?

The Trading Allowance lets you earn up to £1,000 from trading/selling activities tax-free. Above £1,000, you can either deduct the flat £1,000 allowance or your actual expenses — whichever gives a lower taxable profit. You cannot claim both.

What eBay expenses can I deduct?

Deductible eBay expenses include: eBay final value fees (typically 12.8% + 30p), PayPal/payment processing fees, postage and packaging costs, cost of goods purchased for resale, eBay subscription fees (Shops), and photography/listing equipment.

Does eBay report seller income to HMRC?

Yes — since January 2024, eBay and other online marketplaces are required under UK DAC7 rules to report seller income to HMRC. If you sell 30+ items or earn over €2,000 (approximately £1,700), eBay will share your data with HMRC automatically.

When does eBay selling become a business?

HMRC looks at 'badges of trade': frequency and volume of sales, profit motive, buying specifically to resell, similar items sold regularly. Casual selling of personal items is not trading — but regular purchasing for resale almost certainly is.

What if I only sell my own personal items?

Selling personal possessions you already own (not bought for resale) is generally not taxable trading income. However, if items sold for profit exceed £6,000 each, Capital Gains Tax may apply. Keep records to distinguish personal vs. trading sales.

How do I register as self-employed for eBay selling?

Register for Self Assessment at gov.uk/register-for-self-assessment by 5 October after the tax year you started trading. Complete your tax return online by 31 January. Pay any tax owed by 31 January each year.

What records should eBay sellers keep?

Keep: monthly eBay seller reports (downloadable from My eBay), purchase receipts for goods, postage receipts, PayPal/bank statements, and records of personal items sold (with evidence they're not for trade). HMRC requires 5 years of records.

Can I use the £1,000 allowance AND deduct expenses?

No — it's one or the other. If your actual expenses exceed £1,000, claim actual expenses for a lower taxable profit. If expenses are less than £1,000, use the Trading Allowance. Compare both methods each year.

Is eBay income subject to National Insurance?

If your eBay profits exceed £12,570 (2026/27 NI threshold) and HMRC classifies you as self-employed, Class 4 NI applies at 9% on profits between £12,570 and £50,270. Most casual sellers won't reach this threshold.

What happens if HMRC investigates my eBay sales?

HMRC uses Connect (a data-matching system) to identify undeclared eBay income. They can access eBay platform data, bank statements, and PayPal records. Penalties for undeclared income range from 0% (unprompted disclosure) to 100% (deliberate concealment).

Do I need to charge VAT on eBay sales?

Only if your annual turnover exceeds £90,000 (VAT registration threshold). Most eBay sellers are below this. If you sell goods from non-UK suppliers via eBay, different rules may apply — especially for goods stored in UK warehouses.
