Stamp Duty calculator

See the Stamp Duty Land Tax (SDLT) on a property purchase in England or Northern Ireland, with a per-band breakdown, first-time-buyer relief and the additional-property surcharge. Scotland and Wales use their own devolved taxes.

Buying a home usually means Stamp Duty (SDLT) on top of the price. Here's the illustrative estimate for England & Northern Ireland — first-time-buyer relief and the additional-property surcharge included. A solicitor confirms the actual figure.

This calculator, the result and the breakdown are free for everyone, no account needed.

How it works

  1. 1Enter the purchase price of the property.
  2. 2Tell it whether you're a first-time buyer, since first-time buyers qualify for relief on eligible purchases.
  3. 3Flag if it's an additional property — a second home or buy-to-let — which adds a surcharge on each band.
  4. 4The calculator applies the SDLT bands slice by slice and shows the tax on each band and the total.

Worked example

A £300,000 home in England or Northern Ireland, bought by someone who is not a first-time buyer and isn't buying an additional property. The calculator works out the SDLT due on each price band and adds them up to a total, shown with the effective rate.

Purchase price£300,000
Stamp Duty (SDLT) due£5,000
Effective rate1.67%

Stamp Duty applies in England and Northern Ireland. Scotland (LBTT) and Wales (LTT) have their own separate taxes, which this calculator flags rather than guesses.

Frequently asked questions

How much is Stamp Duty on a £300,000 house?

It's worked out band by band, not as a flat percentage. Enter £300,000 and the calculator shows the tax on each band and the total for England or Northern Ireland.

Do first-time buyers pay Stamp Duty?

First-time buyers qualify for relief on eligible purchases, which reduces or removes the SDLT up to a threshold. Tick the first-time-buyer option to apply it.

Is there Stamp Duty in Scotland and Wales?

Not SDLT. Scotland charges Land and Buildings Transaction Tax (LBTT) and Wales charges Land Transaction Tax (LTT). This calculator covers England and Northern Ireland and flags the others rather than estimating them.

What is the additional-property surcharge?

If you're buying a second home or a buy-to-let and it's not replacing your main residence, a surcharge is added to each SDLT band. Flag the additional-property option to include it.
