UK Stamp Duty Calculator (SDLT)
Estimate Stamp Duty Land Tax (SDLT) on a residential property purchase in England or Northern Ireland.
Stamp Duty Land Tax (SDLT) applies to property purchases in England and Northern Ireland (Scotland has Land and Buildings Transaction Tax, and Wales has Land Transaction Tax — both different). This calculator uses the standard residential rates for a main home, which reverted to their standard thresholds from 1 April 2025. It does not include first-time buyer relief or the additional-property surcharge.
Example
- With the default values shown above, this calculator returns: Stamp Duty Owed ≈ £7500.00; Effective Rate ≈ 2.14%.
Frequently Asked Questions
Does this apply to first-time buyers?
No — first-time buyers get relief (0% up to £300,000, with a special rate up to £500,000) which this calculator does not model. If you're a first-time buyer, your actual SDLT is likely lower than shown here.
Does this apply in Scotland or Wales?
No. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT), both with different rates and bands.
