About stampdutycalc.uk

We started this site in early 2026 after a frustrating experience buying our first flat in Bristol. Our solicitor quoted three different stamp duty figures across two weeks — £4,750, then £4,500, then back to £4,750. Each time, the explanation was different. The HMRC calculator gave a fourth number because it didn't account for our specific completion date.

We figured if we were confused, plenty of other buyers were too. So we built calculators that show exactly how the tax breaks down, band by band, with the current official rates from HMRC, Revenue Scotland, and the Welsh Revenue Authority.

What we do

We run free stamp duty calculators for England, Scotland, and Wales. Each one uses the same progressive band logic as the official tax authorities, with toggles for first-time buyer relief, additional property surcharges, and non-UK resident charges where they apply.

We also write guides that explain how these taxes actually work — with real numbers, not vague generalities. No financial advice, no lead generation, no conveyancing referrals. Just the maths, clearly laid out.

What we don't do

We're not solicitors, tax advisers, or mortgage brokers. Our calculators are for guidance and planning purposes. Your actual tax liability depends on your specific circumstances, and you should always confirm figures with your conveyancer before exchanging contracts.

We don't sell your data, show ads, or charge for anything. The site exists because we wished it existed when we were buying.

Keeping rates current

Tax rates change — usually in autumn budgets. We update our calculators when official rates change and note the source date on every page. If you spot a discrepancy between our figures and the official guidance, please let us know.
