You buy a 40-piece clothing bundle at a car boot for £20, grab three jumpers from a charity shop for £8, and flip them all on Vinted. Then the tax return looms and you realise you've kept almost no paperwork. How are you supposed to work out your cost of goods sold when there are no receipts to point at?
This is the single most common worry we hear from resellers, and the good news is that HMRC has a sensible answer. You don't need a till receipt for every item to claim its cost. You do need to keep proper records going forward, make a genuine, reasonable estimate where the paperwork is gone, and be honest about it.
This guide is for UK resellers selling second-hand and bundled stock, especially on Vinted, eBay and similar apps. We'll cover when your selling is even taxable, how to value stock and work out cost of goods sold without receipts, and how to stay on the right side of HMRC.
What counts as a taxable reseller, not just someone clearing out a wardrobe?
If you buy or make things to sell on at a profit, HMRC treats you as trading, and profits above the £1,000 trading allowance are taxable. Selling your own old belongings usually is not taxable at all.
That line matters more than any receipt. HMRC's own guidance for digital platform sellers puts it plainly: "You're unlikely to pay tax if you sell personal items from your home, like contents of a loft or garage," but "If you buy or make goods to sell at a profit, you're likely to be trading and will have to pay tax on your profits" (gov.uk, selling goods or services on a digital platform).
So a one-off clear-out of your own wardrobe is not a trade. Buying charity-shop and car-boot stock specifically to flip is.
How does HMRC decide if I'm trading? The badges of trade
When it's not obvious, HMRC looks at the "badges of trade". These are nine pointers it weighs up together, and no single one is decisive (gov.uk, BIM20205):
- Profit-seeking motive
- The number of transactions
- The nature of the asset
- Existence of similar trading transactions or interests
- Changes to the asset
- The way the sale was carried out
- The source of finance
- Interval of time between purchase and sale
- Method of acquisition
A reseller buying bundles to break up and sell on at a profit, repeatedly, ticks most of these. If that's you, you're trading, and the rest of this guide applies. If you're genuinely just selling your own used clothes, see the question on Capital Gains Tax further down.
Do the platform reporting rules mean I'll definitely be taxed?
No. From 1 January 2024, UK digital platforms such as Vinted and eBay must report seller data to HMRC. A platform will let you know your details have been shared once you pass a reporting trigger, and your details are not reported if in a calendar year you make fewer than 30 sales of goods and receive less than 2,000 euros, about £1,700, for those sales (gov.uk, selling goods or services on a digital platform).
Being reported is not the same as owing tax. The reporting threshold is just a data-sharing trigger. Whether you owe anything still depends on whether you're trading and what your profit is.
How do I value reseller stock and cost of goods sold with no receipts?
Cost of goods sold is what you paid for the stock you actually sold in the year. With no receipts, you rebuild it from the records you do have plus a fair, reasonable estimate, and you tell HMRC if any figures are estimated.
HMRC accepts that records sometimes go missing. Its guidance is clear: "If you cannot replace your records, you must do your best to provide figures," and you tell HMRC when you file whether you're using estimated figures, your best guess where you cannot get the actual numbers, or provisional figures, temporary estimates while you wait for the real ones (gov.uk, business records if you're self-employed).
So a missing receipt does not mean you lose the deduction. It means you make a defensible estimate and flag it.
Step 1: Gather every record that isn't a receipt
You almost always have more evidence than you think. Pull together:
- Bank and card statements showing cash withdrawals before car-boot trips, or card payments to charity shops and wholesalers.
- Your platform payout reports from Vinted, eBay and similar, which give you sales income for the year.
- Photos with dates, messages arranging bundle purchases, and any seller notes.
- A contemporaneous note or spreadsheet, even a rough one, of what you bought and paid.
Recreate as much as you can. HMRC expects you to try, for example by asking a bank for statements or a supplier for a duplicate invoice, before falling back on estimates.
Step 2: Choose a reasonable, consistent valuation method
Where you bought a job lot and have no per-item price, allocate the total you paid across the items in a sensible, repeatable way. The accounting principle HMRC works to is that cost means all the costs of bringing the stock to its sellable condition, and where exact cost can't be pinned down you aim for "the closest practical approximation to historical cost" (gov.uk, BIM33135).
Two practical, defensible approaches:
- Equal split. A £20 bundle of 40 items is £0.50 each. Simple, and fine where items are broadly similar.
- Weighted split. Where some pieces are obviously worth more, split the total in proportion to expected sale value. A coat worth ten times a t-shirt carries ten times the cost.
Pick one method, write down your reasoning, and use it consistently. Consistency is what makes an estimate credible.
Step 3: Decide whether you even need a closing stock figure
Under traditional (accruals) accounting you must value unsold stock at the year end, at the lower of cost and net realisable value (gov.uk, BIM33135). Net realisable value is roughly what you could sell it for, less selling costs.
But from the 2024/25 tax year the cash basis is the default way for sole traders to record income and expenses. As gov.uk puts it: "Cash basis accounting is the standard way to record your income and expenses if you're a sole trader or partnership without corporate partners," and "You can choose to use traditional accounting instead" (gov.uk, cash basis).
The cash basis is a real simplification for resellers. You record a stock purchase as an expense when you pay for it, so you don't have to value opening and closing stock at all. For someone juggling car-boot bundles and charity-shop finds, that removes the hardest part of the maths.
Should I claim actual costs or the £1,000 trading allowance?
If your reseller income is £1,000 or less in the tax year, the trading allowance covers it and there's nothing to report. Above £1,000, you choose: deduct the flat £1,000 allowance, or deduct your actual costs. You cannot do both.
The £1,000 trading allowance is the first £1,000 of self-employment income, tax-free (gov.uk, tax-free allowances on property and trading income). If your gross sales are under it, you don't even need to report the income.
If you're over £1,000, run the comparison. Where your real costs, stock plus postage, packaging, platform and payment fees, and mileage, come to more than £1,000, claim actual costs. Where your costs are low and you've lost the paperwork, the flat £1,000 allowance can be the cleaner, fully-allowable option with no estimating needed.
Illustrative example: a Vinted bundle reseller in 2025/26
Priya resells clothing on Vinted, sourcing bundles from car boots and charity shops. For 2025/26 her Vinted payout reports show gross sales of £8,400. She kept a rough spreadsheet of stock spend but few actual receipts. She uses the cash basis.
| Item | Amount |
|---|---|
| Gross sales (from platform payout reports) | £8,400 |
| Stock bought and paid for in the year (estimated from notes and cash withdrawals) | £2,900 |
| Postage, packaging, platform and payment fees, mileage | £1,150 |
| Total allowable costs | £4,050 |
| Taxable profit | £4,350 |
Profit is £8,400 minus £4,050, which is £4,350. The trading-allowance alternative would let her deduct just £1,000, leaving £7,400 taxable, so claiming actual costs is far better here.
Because some stock figures are estimated, Priya notes on her return that she's used estimated figures and keeps her spreadsheet and bank statements to back them up. Her profit of £4,350 is below the £12,570 personal allowance for 2025/26, so on these figures no Income Tax is due, and as the profit is below the £12,570 Class 4 Lower Profits Limit there's no Class 4 National Insurance either (gov.uk, self-employed National Insurance rates). She still has to report it, because gross income is over the £1,000 trading allowance.
This is an illustrative example to show the method. Your own figures, allowances and other income will change the result.
Do I ever pay Capital Gains Tax instead of Income Tax?
Only if you're not trading. If you sell a personal possession that isn't part of a resale business, Capital Gains Tax can apply where the item fetches £6,000 or more.
HMRC charges Capital Gains Tax on "most personal possessions worth £6,000 or more, apart from your car" (gov.uk, Capital Gains Tax, what you pay it on). Everyday used clothing sold for a few pounds is well under that, so a genuine wardrobe clear-out almost never triggers it. For resellers who are trading, this doesn't apply: your profits are taxed as trading income, not capital gains.
Will I need to register for VAT?
Almost certainly not as a small reseller. VAT registration is only compulsory once your taxable turnover passes £90,000 in a rolling 12 months.
The current VAT registration threshold is £90,000 (gov.uk, VAT registration thresholds). Most resellers are nowhere near it. If you ever do approach that level, the VAT margin scheme for second-hand goods can let you pay VAT only on your margin rather than the full sale price, but that's a separate, more advanced topic. Talk to us before you get close.
How long do I keep records, and what if I lose them again?
Keep records for at least five years after the 31 January filing deadline for that tax year, and if records are lost, do your best to recreate them and tell HMRC you're using estimated or provisional figures.
The rule is specific: "You must keep your records for at least 5 years after the 31 January submission deadline of the relevant tax year" (gov.uk, business records if you're self-employed).
Going forward, the fix is simple. Log every purchase the moment you make it. A dated phone note or a single spreadsheet row, what you bought, how many items, and what you paid in total, is enough to turn next year's "no receipts" panic into a two-minute job.
If you're building a Vinted resale business and want the bookkeeping handled properly, our accountants for Vinted sellers set up simple stock and sales tracking so your cost of goods sold is always defensible. You can also keep an eye on your likely bill with our self-employed tax calculator, and when you're ready to file, our self-assessment service takes the return off your plate.
Key takeaways
- A missing receipt doesn't kill the deduction. Make a reasonable, consistent estimate and tell HMRC it's estimated.
- You're only trading if you buy or make goods to sell at a profit. A genuine wardrobe clear-out usually isn't taxable.
- Income of £1,000 or less is covered by the trading allowance with nothing to report. Above it, claim actual costs or the £1,000 allowance, never both.
- The cash basis is the default from 2024/25 and lets resellers skip valuing opening and closing stock.
- Keep records for five years after the 31 January deadline, and log every purchase as you go.
Frequently asked questions
Can I claim stock costs if I have no receipts at all?
Yes. HMRC accepts that records sometimes can't be replaced and says you must do your best to provide figures, using estimated or provisional amounts and telling HMRC you've done so. Use bank statements, platform payout reports and your own notes to support a reasonable estimate.
How do I split the cost of a job-lot bundle across items?
Allocate the total you paid in a sensible, consistent way. An equal split works where items are similar, for example a £20 bundle of 40 items at £0.50 each. Use a weighted split based on expected sale value where some pieces are clearly worth more. Write down your method and stick to it.
Do I have to value my unsold stock at the year end?
Not if you use the cash basis, which is the default for sole traders from the 2024/25 tax year. Under the cash basis you deduct stock when you pay for it, so there's no opening or closing stock valuation. Only traditional accounting requires year-end stock valued at the lower of cost and net realisable value.
Vinted shared my details with HMRC. Does that mean I owe tax?
Not automatically. Since 1 January 2024 platforms report seller data once you pass a trigger, broadly 30 or more sales or about £1,700 in a year. Being reported just means HMRC has the data. Whether you owe tax depends on whether you're trading and what your profit is.
Is selling my own old clothes on Vinted taxable?
Usually not. Selling personal items you owned for your own use is generally not taxable, and Capital Gains Tax only bites on personal possessions worth £6,000 or more (cars excepted). Buying stock specifically to resell at a profit is trading, and that's taxable above the £1,000 trading allowance.
