These terms govern your use of StampDutys.com and its free UK stamp duty, mortgage and property calculators. Please read them before using the site — by using StampDutys.com you agree to be bound by them.
By accessing or using StampDutys.com (the "site"), you agree to be bound by these Terms of Service. If you do not agree with any part of these terms, please do not use the site. We may update these terms from time to time, and continuing to use the site after changes are posted means you accept the revised terms.
StampDutys.com provides free, publicly accessible calculators covering UK Stamp Duty Land Tax (SDLT), Land Transaction Tax (LTT), Land and Buildings Transaction Tax (LBTT), mortgages, rental yield, conveyancing fees, capital gains tax and related property topics. These tools are provided for general informational and illustrative purposes only, to help you get a rough idea of figures that may apply to a property transaction.
The calculators on this site produce estimates only. They are not, and must never be treated as, tax advice, legal advice, financial advice or mortgage advice. The figures shown are based on simplified assumptions about current rates, thresholds and rules, and may not reflect your exact personal or property circumstances, any reliefs or surcharges you may or may not qualify for, or recent changes to legislation.
Before relying on any figure from this site for a real property transaction, mortgage application or financial decision, you should always verify it with the official calculators and guidance published by HMRC, Revenue Scotland or the Welsh Revenue Authority, and seek advice from a qualified, regulated professional — such as a solicitor or licensed conveyancer, a chartered accountant or tax adviser, or an FCA-regulated financial or mortgage adviser, as appropriate.
We do not accept responsibility or liability for any decision made, or action taken, in reliance on the information or calculations provided by this site. Use of these tools is entirely at your own risk.
We make reasonable efforts to keep the rates, thresholds and rules used in our calculators up to date and consistent with current UK legislation. However, tax rates, thresholds and mortgage criteria change periodically — sometimes with little notice — and there may be a delay between an official change taking effect and this site being updated to reflect it. We give no guarantee, warranty or representation, express or implied, that any information or calculation on this site is complete, accurate, current or error-free.
The design, layout, text, graphics, calculator logic and underlying code of StampDutys.com are owned by StampDutys.com and are protected by copyright and other intellectual property laws. You may not copy, reproduce, republish or distribute any part of the site itself without our permission. The output figures you personally generate by entering your own numbers into a calculator are yours to use, save, print or share freely.
This site links to gov.uk, HMRC, Revenue Scotland, the Welsh Revenue Authority and other official or third-party sources for your convenience, so you can verify figures or find further guidance. We do not control these external sites and are not responsible for their content, accuracy, availability or any consequences of your use of them.
