Stamp Duty Land Tax calculator 2026

When to use this calculator

For a single ordinary residential purchase with an effective date in 2026, where neither higher rates for additional dwellings nor the non-UK-resident surcharge apply. The amount is rounded down to whole pounds. First-time buyer relief is available only if all eligibility conditions are met and the consideration is no more than £500,000; above that amount the standard rates apply.

This estimate excludes additional-property and non-resident surcharges, corporate higher rates, linked transactions, shared ownership, rent on leases, mixed-use property and other reliefs or exemptions. It does not calculate taxes for Scotland or Wales. Check the applicable rules and use the HMRC calculator for your circumstances.
