Stamp Duty (SDLT)

Estimate only, for England/Northern Ireland SDLT rates. Scotland (LBTT) and Wales (LTT) use different bands, not covered here. Not financial advice.

How UK stamp duty works

Stamp Duty Land Tax (SDLT) is charged in bands: you pay 0% on the portion of the price up to £125,000, 2% on the next slice up to £250,000, 5% up to £925,000, 10% up to £1.5m, and 12% above that. Only the portion of the price inside each band is taxed at that band's rate, not the whole price at the top rate.

Buying an additional property, including any buy-to-let, adds a flat 5% surcharge on top of every band, including the portion that would otherwise be tax-free. First-time buyers get relief instead: 0% up to £300,000 and 5% from £300,000 to £500,000, but only if the price is £500,000 or under. Above that, first-time buyer relief doesn't apply at all and standard rates apply to the whole price.

Common questions

What is the stamp duty surcharge for buy-to-let in the UK?

An additional 5% on top of the standard SDLT bands, applied to the whole purchase price including the portion that would otherwise be tax-free for a main residence. It applies to any additional property, not just buy-to-let specifically.

Do first-time buyers pay stamp duty?

First-time buyers pay 0% up to £300,000 and 5% on the portion from £300,000 to £500,000. This relief only applies if the total price is £500,000 or under, above that, standard rates apply to the whole price with no first-time buyer relief at all.

Is stamp duty different in Scotland or Wales?

Yes. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT), both with different bands and rates from SDLT. This calculator covers England and Northern Ireland only.

How is stamp duty calculated on a buy-to-let property?

The same banded rates as a standard purchase (0% up to £125,000, 2% up to £250,000, 5% up to £925,000, 10% up to £1.5m, 12% above), plus a flat 5% surcharge on the whole price for buying an additional property rather than a main residence.
