Frequently asked questions
How much stamp duty does a first-time buyer pay?
Nothing on the first £300,000, then 5% on the portion from £300,001 to £500,000. If the property costs more than £500,000, first-time buyer relief doesn't apply and standard rates are charged on the whole price.
What is the surcharge on second homes?
Buying an additional residential property adds 5 percentage points to every band, on top of standard rates. It applies to second homes and buy-to-lets costing £40,000 or more.
Does this calculator work for Scotland or Wales?
No — Scotland charges LBTT and Wales charges LTT, which have different bands. This calculator covers SDLT in England and Northern Ireland only.
When do I pay stamp duty?
Your solicitor normally files the return and pays HMRC on completion. The legal deadline is 14 days after completion.
