What HMRC says, the records worth keeping, and the tools that help. To be upfront: we list one dedicated tracker (Trackerly). The rest is spreadsheets and the records built into tools you may already use.

HMRC says you need to tell it if you earn more than £1,000 in a tax year from buying things to sell for profit, and that the £1,000 is before expenses, not profit. HMRC says platforms share data with it once you sell 30 or more items a year; gov.uk's digital-platform reporting guidance says platforms don't need to report sellers with fewer than 30 sales and 2,000 euros or less (approximately £1,700) a year. Keep a record of cost, sale price, fees and postage for every item, in a spreadsheet or an app such as Trackerly (£14.99 a month, 7 days free).
This page isn't tax or accounting advice. Use HMRC's guidance or an accountant for your situation.
Vinted's terms restrict bots, automation tools and bulk relisting. Accounts can be warned, limited or blocked. What Vinted's rules say
From HMRC's Tax help for hustles (read 19 Oct 2026):
Gov.uk's reporting rules for digital platforms give the fuller rule: platforms don't need to report sellers with fewer than 30 sales and 2,000 euros or less (approximately £1,700) a year.
The key point for resellers: £1,500 of sales with £1,200 of costs is still more than £1,000 earned on HMRC's wording, even though the profit is £300. That's why records of sales, not just profit, matter.
As good practice, for every item:
Plus running costs such as tool subscriptions. Whether and how you can deduct those is a tax question: see HMRC's guidance.
A spreadsheet with one row per item and the columns above is free and fully yours. It suits a few sales a week. The cost is time: you copy in every sale, fee and postage charge by hand. An app earns its keep when that copying takes longer than the subscription is worth to you, typically once you sell on several platforms.
A desktop tracker for "real profit after platform fees, postage and expenses", with expenses, income and a tax-year summary.
Per its help centre, Trackerly produces "a tax-year profit and loss you can hand your accountant, on an accrual or cash basis". It connects to eBay for payouts and the fees eBay charged, and reads your Vinted account (sold orders, wardrobe, wallet) "through your own signed-in session on your own machine". It also shows a running VAT-threshold total. Its pricing page says it doesn't take a cut of your sales, and its footer says "It isn't tax or accounting advice." We haven't tested it.
Trackerly connects eBay and Vinted and reads order emails, so check the Security page linked in the footer of Trackerly's site before connecting accounts.
Because Trackerly reads Vinted through your own logged-in session, Vinted's rules on external tools are worth a read: see the note above.
These help you see sales, but none says it's built for tax-year records the way Trackerly does. You'd still need costs and expenses from somewhere.

Record each item's cost, where and when you bought it, the sale price, platform fees, postage and any refunds. Profit is sale price minus all of those. A spreadsheet works; apps such as Trackerly pull in sales and fees for you.
HMRC says selling unwanted personal belongings from time to time usually doesn't need reporting. If you earned more than £1,000 in a tax year from buying or making things to sell for profit, you need to tell HMRC. This isn't tax advice.
Sales. HMRC says it's "the amount you earn before factoring in expenses. It is not the same as profit."
As good practice: purchase date, cost and source; the platform and sale date; sale price; fees; postage and packaging; refunds and returns; and receipts. Keep them for the whole tax year and beyond.
We haven't tested it, so we can't judge. It's £14.99 a month or £149.99 a year, with 7 days free. It connects eBay and Vinted, reads orders from your email, and runs on Windows and macOS with your data on your own computer. Try the free week alongside a spreadsheet.
HMRC says platforms "must now share information with HMRC if you sell 30 items or more a year through their service", and that this "doesn't mean you necessarily owe tax or need to do anything". Gov.uk's digital-platform reporting guidance adds that platforms don't need to report sellers with fewer than 30 sales and 2,000 euros or less (approximately £1,700) a year.
