An estimate, not advice
This calculator provides an estimate only and is not tax or legal advice. SDLT depends on your circumstances. Confirm the amount with your solicitor, conveyancer or HMRC before completing a purchase.
- It covers residential, non-residential and mixed-use purchases in England and Northern Ireland.
- Scotland uses Land and Buildings Transaction Tax (LBTT) instead.
- Wales uses Land Transaction Tax (LTT) instead.
- Complex transactions may need specialist advice.
Not covered here: purchases by companies or trusts, shared ownership, linked transactions, purchases of six or more properties, new leases involving rent, and reliefs beyond the choices above. For any of those, speak to HMRC and your solicitor or conveyancer rather than relying on this page.
Rates cover completion dates from 23 September 2022 onwards, across the three published rate periods since then. Last verified 7 August 2026.

A member of the Dukes team can talk through the purchase or sale itself — not the tax, which stays between you, your conveyancer and HMRC.
