Buying

Stamp duty calculator

The tax bill you may face when buying in England or Northern Ireland.

  • What it means

    Stamp duty is a tax you may pay when you buy a home in England or Northern Ireland. This estimates that bill.

  • Why it matters

    It is often thousands of pounds on top of the deposit, and it is due around completion day.

  • When to use it

    Use it whenever the price or your buyer type changes: first home, next home, or an extra property.

  • How to read the result

    The result is cash you need besides the deposit. First-time relief and extra-property surcharges change the figure a lot, so pick the right scenario.
