Frequently Asked Questions
Is the calculator accurate?
Our calculator uses the latest SDLT rates from April 2026, which remain current for 2026. However, always verify with HMRC or a professional for official purposes.
Does it work for Scotland or Wales?
No, this calculator is for England and Northern Ireland only. Scotland uses LBTT and Wales uses LTT - different tax systems.
Why are results different from HMRC?
Small differences may occur due to rounding. Our calculator rounds down to the nearest pound, as is standard practice.
Can I claim first-time buyer relief?
You may qualify if you've never owned property before and the purchase price is £500,000 or less. Check with your solicitor for eligibility.
