UK Stamp Duty Calculator

Stamp duty land tax (and the devolved equivalents) is one of the biggest upfront costs when buying property in the UK. Rates and thresholds differ between England & Northern Ireland (SDLT), Scotland (LBTT) and Wales (LTT).

This free calculator lets you choose the nation, enter the purchase price, and optionally apply first-time buyer or additional property rules where they apply. Everything runs client-side so your figures stay private.

Tax rules change over time. Figures are based on commonly published residential rates and are for guidance only — confirm with a solicitor or the official HMRC / Revenue Scotland / WRA guidance before exchanging contracts.

Frequently asked questions

What is the difference between SDLT, LBTT and LTT?
SDLT applies in England and Northern Ireland. Scotland uses Land and Buildings Transaction Tax (LBTT). Wales uses Land Transaction Tax (LTT). Each has its own rates and thresholds.
Does this cover commercial property?
This tool focuses on residential property purchases. Commercial and mixed-use rates differ — check official guidance for those cases.
Are first-time buyer reliefs included?
Yes, where the nation offers first-time buyer relief and you select that option. Eligibility rules (e.g. never owned property, intended main residence) still apply in law.
What about the additional dwellings surcharge?
You can model an additional property surcharge for England & NI and equivalent higher rates where supported. Rules on replacements of a main residence can be complex — seek advice if unsure.
When is stamp duty payable?
Usually within 14 days of completion for SDLT (deadlines can differ by nation). Your conveyancer typically files the return and arranges payment.
