Stamp Duty Calculator UK

What This Calculator Estimates

Stamp Duty Land Tax (SDLT) in the UK (or Land and Buildings Transaction Tax in Scotland, Land Transaction Tax in Wales) is a property purchase tax administered by HMRC and the relevant devolved authorities, calculated on a progressive band system based on property price, with different rates and thresholds for first-time buyers, additional properties, and standard purchases. Because bands and reliefs vary significantly by nation within the UK and buyer circumstances, this calculator provides a general estimate — confirm exact figures against current official rate tables.

Frequently Asked Questions

Is Stamp Duty the same across the whole UK?

No, England and Northern Ireland use Stamp Duty Land Tax (SDLT), Scotland uses Land and Buildings Transaction Tax (LBTT), and Wales uses Land Transaction Tax (LTT) — each has its own bands and rates.

Do first-time buyers get a discount?

Yes, first-time buyers typically benefit from relief or a higher nil-rate threshold compared to standard purchasers — check current thresholds for your nation.

Does buying an additional property increase the rate?

Yes, purchasing an additional residential property (such as a second home or buy-to-let) typically incurs a surcharge on top of standard rates in most parts of the UK.

Is Stamp Duty progressive like income tax?

Yes, it's calculated across bands, so different portions of the purchase price are taxed at different rates rather than one flat rate applying to the whole amount.

Where can I confirm current official rates?

HMRC (for SDLT) or the relevant devolved tax authority (Revenue Scotland for LBTT, Welsh Revenue Authority for LTT) publish current band tables.

This calculator provides UK stamp duty estimates only. Official thresholds, bands, and surcharges can change, so verify current rules before relying on the result.
