SDLT calculator
Estimate residential Stamp Duty Land Tax for a straightforward purchase.
Residential SDLT estimator
Calculate estimated SDLT.
For a straightforward residential purchase in England or Northern Ireland. Standard rates effective from 1 April 2025 are used.
Estimate only. It does not cover all reliefs or special rules. Check the current residential SDLT rates on GOV.UK before relying on an estimate.
SDLT needs the full transaction facts
This estimate is for a straightforward residential purchase in England or Northern Ireland. The property type, purchase price, buyer circumstances and whether the purchase is an additional dwelling can all affect the result.
Company purchases, trusts, leaseholds, mixed-use property, linked transactions and reliefs may need a different analysis. Scotland has LBTT and Wales has LTT rather than SDLT. Seek advice before exchange or completion if the transaction is not straightforward.
Check before you commit
Tax is only one part of a property decision, but it is important to understand it before signing contracts. Keep the figures with your transaction documents and ask for advice where the facts are unusual.
