How to use this ebay tax calculator uk
Use this eBay tax calculator to estimate UK tax where your eBay sales are taxable trading income, such as reselling stock or running a small online shop alongside PAYE work.
A one-off sale of household possessions is not the same as trading. Use the calculator for profit-seeking eBay activity and keep personal clear-outs separate from business records.
Personal item sales are not automatically taxable. Repeated buying for resale, business-like listings and profit-seeking activity are stronger signs of taxable trading.
- Use Side Hustle Income for gross income before expenses or allowances.
- Use Side Hustle Expenses for allowable expenses, or for the deduction you want to model, such as the trading allowance.
- Use Annual Salary for your PAYE salary before tax.
Trading Allowance vs Actual Expenses
The trading allowance can exempt up to £1,000 of gross trading income. If your gross trading income is £1,000 or less, you may not need to tell HMRC, although some circumstances still require a tax return.
If gross trading income is more than £1,000, you can usually choose between deducting the £1,000 trading allowance or deducting actual allowable expenses. You cannot claim both for the same trade.
Self Assessment registration and deadlines
If you cross the £1,000 trading allowance you normally need to register for Self Assessment by 5 October after the tax year ends, and file online by 31 January after the tax year. See the main Self Assessment registration and deadlines section for the 2025/26 dates and payments-on-account rules.

FAQs
Do I pay tax on eBay sales in the UK?
You may need to pay tax if the sales are part of a taxable trade. Occasional sales of personal possessions are usually treated differently from buying and reselling for profit.
Are personal item sales taxable?
Selling personal possessions is not automatically taxable trading. Capital gains rules can apply to some valuable assets, but ordinary household clear-outs are usually outside trading income.
Does eBay report income to HMRC?
Platforms may share seller information with HMRC. That does not mean every seller owes tax; you still assess whether your activity is taxable trading or another taxable source.
Can I deduct eBay fees and postage?
If you are trading, eBay fees, postage, packaging and cost of goods are typical business costs to consider when calculating taxable profit.
What if I sell at a loss?
A genuine trading loss can be more complex than a simple calculator estimate. If you regularly make losses, check HMRC guidance or speak to an adviser.
When should I register as self-employed?
You normally register for Self Assessment if gross trading income is over £1,000 in the tax year or if HMRC otherwise requires a tax return.
