Stamp Duty Calulator

This Stamp Duty Land Tax (SDLT) calculator estimates the amount of stamp duty payable when purchasing a residential property in England. It applies the current SDLT rates based on your buyer status, including first-time buyers, standard residential buyers, and additional property or buy-to-let purchases.

The calculation uses the marginal (banded) tax system, meaning each portion of the property price is taxed at the applicable rate rather than a single flat rate. Select the option that best describes your situation to receive an accurate estimate of the stamp duty due.

This calculator is for guidance only and does not replace professional tax or legal advice.
