What this means

Stamp Duty Land Tax is calculated in bands, so you only pay each rate on the portion of the property price within that band.

How does stamp duty work in England and Northern Ireland?

Stamp Duty Land Tax, often shortened to SDLT, is a tax paid when buying property or land in England and Northern Ireland. The amount depends on the property price, whether you are a first-time buyer, and whether the purchase is an additional property.

SDLT is calculated in bands. This means you do not usually pay one flat rate on the whole property price. Instead, different parts of the price are taxed at different rates.

First-time buyer relief can reduce the amount due on eligible purchases, while additional residential properties usually attract higher rates. Scotland and Wales have separate property tax systems, so this calculator is focused on England and Northern Ireland only.

Main home purchase

Uses the standard SDLT residential bands for England and Northern Ireland.

First-time buyer

May qualify for reduced SDLT if the property price is within the eligible relief limit.

Additional property

Usually attracts higher SDLT rates, often relevant for second homes or buy-to-let purchases.

How to use this result

Use the stamp duty estimate when working out your total upfront buying costs. It is often one of the largest extra costs after your deposit.

First-time buyer relief can reduce SDLT on eligible purchases up to £500,000. Above that price, standard rates apply.

This calculator is an estimate only. Your solicitor or conveyancer should confirm the exact amount due.

FAQs

Where does this calculator apply?

It applies to residential property purchases in England and Northern Ireland. Scotland and Wales use different property tax systems.

What are the first-time buyer rules?

Eligible first-time buyers pay no SDLT up to £300,000 and 5% on the portion from £300,001 to £500,000. If the price is over £500,000, standard rates apply.

Do additional properties cost more?

Yes. Additional residential properties normally have higher SDLT rates than a main home purchase.

When do you pay stamp duty?

SDLT is normally handled as part of the purchase process, and your solicitor or conveyancer will usually submit the return and confirm the amount due.

What does effective rate mean?

The effective rate shows the total stamp duty as a percentage of the property price. It is an average figure, not the same as the banded SDLT rates.

Is this calculator financial advice?

No. This calculator gives a general estimate only. You should confirm the exact SDLT amount with your solicitor, conveyancer, or HMRC guidance.
