For UK eBay, Vinted & Depop sellers
Know exactly what you owe HMRC on your online sales.
FlipTally shows your true profit after fees and postage, and gives you a clear, calm estimate of your tax — trading allowance, Self Assessment, the lot. No jargon. No spreadsheet.
No signup to use the calculator. Updated for the 2026/27 tax year.
The free reseller tax check
Answer three quick questions. See instantly whether you owe anything, whether you need to tell HMRC, and roughly how much to set aside.
Your numbers
Nothing is saved. Nothing to sign up for. Just answers.
Everything buyers paid you, before fees — 6 Apr 2026 to 5 Apr 2027.
Fees, postage, packaging, and what you paid for the stock.
Helps us get your tax rate right — your reselling stacks on top.
For the platform-reporting check — Jan to Dec, not the tax year.
Enter your total sales to see where you stand with HMRC.
Estimates only, not tax advice. Figures for England, Wales & Northern Ireland, 2026/27 tax year. Scotland has different income-tax bands. Always check with an accountant before you file.
The two dates everyone mixes up
This confusion causes most of the panic. They're not the same thing — and FlipTally keeps them straight for you.
🗓️ The tax year — what you owe
6 April 2026 → 5 April 2027
HMRC works out tax on this window. The £1,000 trading allowance and any bill you owe are measured here.
📅 The calendar year — when you get reported
1 January → 31 December
Platforms report you to HMRC on this window if you pass 30+ sales or ~£1,700. Being reported is not the same as owing tax.

A calm, honest tool
- Estimates, never promises. Every figure is clearly an estimate, with conservative assumptions where the rules are fuzzy. We're not accountants and we never pretend to be.
- Your data is yours. We ask for as little as possible, we never touch your eBay password, and you can delete everything whenever you want.
- Built for real sellers. Plain English, mobile-first, and priced for a side hustle — not a finance department.
