⚠️ Disclaimer: Stamp Duty UK Calculator is an independent private app. It is not a government app and is not affiliated with, endorsed by or acting on behalf of HM Revenue & Customs (HMRC), Revenue Scotland or the Welsh Revenue Authority.

Stamp Duty UK Calculator estimates residential property tax for the nation you are buying in. Type a purchase price, pick the nation and see the estimate in pounds.

Features
• Stamp Duty Land Tax (England and Northern Ireland), Land and Buildings Transaction Tax (Scotland) and Land Transaction Tax (Wales)
• First-time buyer and additional dwelling rules where they apply
• Band-by-band breakdown from the 2026 residential rate tables stored on your device, so it works offline
• Optional yearly subscription: saved scenarios, sharing and PDF export, no upgrade banner. The core calculator stays free

Results are estimates only. They are not a tax return and not tax or legal advice. Non-residential, mixed-use and company purchases can differ. Confirm the amount with your solicitor or conveyancer and the official sources.
