What is stamp duty?

Stamp Duty Land Tax (SDLT) is a tax you may need to pay when you buy a residential property in England or Northern Ireland. The amount depends on the purchase price and your circumstances. It’s calculated in bands, so you only pay each rate on the portion of the price within that band.

How much is Stamp Duty?

Stamp Duty depends on the purchase price and your circumstances. Use the points below to understand what can increase or reduce the amount you pay — then use the calculator for an instant estimate.

First-time buyer relief

If you’re buying your first home, you may qualify for a reduced rate. Relief depends on your purchase price and whether everyone buying is a first-time buyer.

Standard residential rates

If you’re moving home and replacing your main residence, Stamp Duty is usually calculated using the standard bands — you pay each rate only on the portion of the price within that band.

Additional property / second home

If you’ll own more than one property after completion (for example a buy-to-let or second home), higher rates often apply, which can increase the overall amount due.

Buying with someone else

Your rate can change depending on who you’re buying with. If anyone on the purchase has owned property before, first-time buyer relief may not apply.

Frequently Asked Questions

How accurate is this Stamp Duty calculator?

It provides an estimate based on the details you enter. Your final Stamp Duty amount can vary depending on your exact circumstances and how the purchase is treated at completion.

When do I pay Stamp Duty?

Stamp Duty is usually paid after completion as part of the conveyancing process. Your solicitor or conveyancer typically handles the return and payment on your behalf.

What information do I need to use the calculator?

You’ll need the property purchase price, your buyer type (first home, next home, or additional property/second home), and an estimated completion date.

How does Stamp Duty work with tax bands?

Stamp Duty is calculated in bands. You only pay each rate on the portion of the purchase price that falls within that band — not on the full amount at one single rate.

Do first-time buyers always pay less Stamp Duty?

Not always. First-time buyers may qualify for relief, but eligibility depends on the purchase price and whether everyone buying the property is a first-time buyer.

Why is Stamp Duty higher for additional properties or second homes?

Additional properties can be charged at higher rates, which increases the overall Stamp Duty due. This often applies if you’ll own more than one property after completion.
