Trading Allowance vs Expenses: Which Should Resellers Use?

Last checked against GOV.UK: 26 October 2026 · General information, not tax advice

The short answer: if your trading income is over £1,000 in a tax year, you can take off either the £1,000 trading allowance or your real allowable expenses, not both. Stock you buy to sell counts as an allowable expense, so resellers whose stock costs more than £1,000 will usually pay tax on a smaller profit by claiming expenses. That only works if you've kept track of what you paid.

First: are you trading at all?

None of this applies to clearing out your own wardrobe. GOV.UK says you're unlikely to pay tax if you sell personal items from your home, and that you're probably trading if you sell goods you bought intending to sell for a profit, or made (GOV.UK). Its own example: someone who regularly buys from car boot sales and charity shops to resell online "may need to tell us about this income". Our Vinted tax guide explains the difference.

How the £1,000 trading allowance works

The trading allowance is a tax exemption of up to £1,000 a year for individuals with trading income (GOV.UK: tax-free allowances). It works on gross income: what you take in before any costs.

The £1,000 is a single allowance across all your side hustles together, not £1,000 per platform. HMRC's example: £800 from content creation and £500 from selling crafts adds up to £1,300, so you'd need to tell HMRC (HMRC: Help for Hustles).

How claiming expenses works

If you're self-employed, you can deduct allowable expenses to work out your taxable profit. GOV.UK's list of allowable expenses includes "things you buy to sell on, for example stock or raw materials" (GOV.UK: expenses if you're self-employed). For a reseller, that's usually the biggest cost.

The catch: GOV.UK says "You cannot claim expenses if you use your £1,000 tax-free 'trading allowance'." It's one or the other.

Worked examples

These are simplified, made-up figures to show the comparison. They only look at stock costs, and they show taxable profit from the side hustle, not a tax bill.

Reseller AUpcycler B
Sales in the tax year (gross)£4,000£2,500
Stock and materials bought to sell£1,800£300
Taxable profit using expenses£2,200£2,200
Taxable profit using the £1,000 allowance£3,000£1,500
Lower figureExpensesAllowance

Reseller A buys most of what they sell, so their stock costs alone beat £1,000. Upcycler B spends little on materials, so the flat £1,000 gives the lower profit. GOV.UK puts it like this: "If your expenses are more than your income it may be beneficial to claim expenses instead of the allowances."

Why resellers often come out ahead with expenses

Reselling is a stock business. If you buy at car boot sales, charity shops or in bundles and sell on Vinted, eBay or Depop, the money you spent on stock can easily pass £1,000 in a year. But you can only claim what you can show. GOV.UK says you must keep records of all sales and income and all business expenses, with proof such as receipts (GOV.UK: what records to keep).

That's the practical problem: many resellers know roughly what they sold (the platforms show it) but not what they paid. Our free profit tracker spreadsheet logs cost and sale price per item, and the SideLedger app we're building will do it for you. Join the waitlist for first access.

Quick answers

Can I claim the £1,000 trading allowance and expenses?

No. GOV.UK says that if you claim the trading allowance you cannot deduct any other expenses or allowances. You use one or the other.

Which is better for resellers, the trading allowance or expenses?

It depends on your numbers. If your allowable expenses, such as the stock you bought to sell, come to more than £1,000, claiming expenses gives a lower taxable profit. If they come to less than £1,000, the allowance usually gives the lower figure. GOV.UK says that if your expenses are more than your income it may be better to claim expenses.

Do I need to keep receipts if I use the trading allowance?

Yes. GOV.UK says you must keep a record of your income if you use the allowance. Keeping receipts for stock is also what lets you claim expenses instead if they turn out to be bigger.
