What is stamp duty?

Most buyers are required to pay stamp duty, with a few exceptions. And besides your mortgage, stamp duty could be your biggest cost as a home buyer.

A stamp duty calculator helps you estimate how much you’ll need to pay. It will take into account the price of your home and the stamp duty rate band it falls into. Read on to find out more.

Stamp Duty Land Tax (SDLT) is a tax in England and Northern Ireland. It usually applies to residential properties – or pieces of land – that cost more than £125,000.

There are exceptions for first time buyers and those buying additional properties, which we’ll explain in this comprehensive guide. (1)

Scotland and Wales have their own taxes, equivalent to stamp duty:

You’ll pay Land and Buildings Transaction Tax (LBTT) in Scotland
You’ll pay Land Transaction Tax (LTT) in Wales

How and when do I pay stamp duty?

As of March 2019, you must pay your stamp duty within 14 days of your move-in date. If it’s not paid by then, you could risk a fine, or having interest added to the amount due. (2)

Traditionally your solicitor deals with your stamp duty payment, but it doesn’t hurt to be aware of what stamp duty is, how it’s calculated, and when it’s due.

Stamp duty is paid as a lump-sum on new properties and second homes, freehold and leasehold properties, and homes bought outright or with a mortgage.

When is stamp duty not applicable?

There are a couple of scenarios where stamp duty land tax doesn’t apply:

If you’re buying a property valued below the stamp duty threshold
If you’re transferring the deeds of your home to someone

Stamp duty in England and Northern Ireland

The standard rate bands for stamp duty are as follows*:

0% stamp duty

on first £0 - £125,000 of property value

2% stamp duty

on next £125,001 - £250,000 of property value

5% stamp duty

on next £250,001 - £925,000 of property value

10% stamp duty

on next £925,001 - £1.5 million of property value

12% stamp duty

above £1.5 million of property value

*Figures accurate as of Aug 2019 as shown at gov.uk

The stamp duty rate you’ll pay isn’t confined to just one of these bands. Each band applies to the equivalent portion of the property price. For example, if you buy a house for £300,000, the stamp duty you’ll pay will be:

The first £125,000 x 0% = £0
The next £125,000 x 2% = £2,500
The final £50,000 x 5% = £2,500

Total stamp duty = £5,000

As you can see, it’s a little complicated, especially on more expensive properties, which is why a stamp duty calculator can be useful.

Stamp duty for first-time buyers in England and Northern Ireland

If you’re a first-time buyer, you’ll be able to benefit from some stamp duty relief on properties up to the value of £500,000.

If you buy a home up to the value of £300,000, you won’t have to pay any stamp duty at all.

If your property costs between £300,000 and £500,000, you won’t have to pay anything on the first £300,000, but you’ll have to pay a rate of 5% for the remaining portion.

For example, on a property that costs £450,000, your stamp duty would be:

The first £300,000 x 0% = 0%
The remaining £150,000 x 5% = £7,500

Total stamp duty = £7,500

To be eligible to receive this discount, you’ll need to meet the following criteria:

All parties involved in purchasing the property must be first-time buyers
Your property can’t exceed a value of £500,00

If you’re a first-time buyer and the property you’re buying is over £500,000, you’ll be required to follow the standard rate bands.

Stamp duty in Scotland

In Scotland, for a single property purchase, no tax is paid on the first £145,000. Then the following rates apply:

2% on the value of the property between £145,000 and £250,000
5% on the part between £250,000 and £325,000
10% on the part from £325,000 to £750,000
12% on any value over £750,000

First-time buyers in Scotland won’t pay stamp duty on the first £175,000.

Stamp duty in Wales

LTT is usually exempt on the first £180,000 of the property, with the following rates applying on the rest:

3.5% between £180,000 and £250,000
5% on the part between £250,000 and £400,000
7.5% on the part between £400,000 and £750,000
10% within the next band up to £1.5 million
12% over £1.5 million

There’s currently no relief for first-time buyers in Wales, but the higher tax free threshold of £180,000 should make most first-time purchases tax-free. (3)

Using a stamp duty calculator

Calculating your stamp duty using a calculator is easy:

You’ll simply need to state whether you’re buying for the first time, buying your next home, or buying an additional property.
You’ll also need to give the value of the property you’re buying, and whether it’s residential or commercial. Some calculators may ask you for the date you plan to complete the sale.

The stamp duty calculator should immediately calculate the total Stamp Duty Land Tax you’ll need to pay, along with a breakdown of how that figure was reached.

There are a range of stamp duty tax calculators out there, including HMRC’s stamp duty calculator.

Your mortgage adviser can provide you with general information on the rates payable. However, if you need advice on any tax implications, then you should speak to an independent tax and legal specialist as mortgage advisers are not qualified to give tax advice.

Buy-to-let stamp duty and stamp duty on a second property

Calculating stamp duty on second homes is different. If you’re buying a second home – perhaps as a holiday home – or a buy-to-let property, you’ll have to pay an additional 3% on the standard stamp duty rates.

This rate applies to properties over £40,000, but excludes mobile homes, houseboats, and caravans.

If you’re buying a new home and selling your old one, you’ll only need to pay the standard stamp duty rates. But if your main residence hasn’t been sold by the time you complete your new purchase, you’ll have to pay the higher rates, because you technically now own two properties.

Thankfully, you can get a refund once you’ve sold your original home – as long as it’s within 36 months of the original purchase.

Buying a leasehold property

Stamp duty applies on both leasehold and freehold properties. It is dealt with exactly the same way on either property.

Buying a commercial property

Calculating stamp duty on land and non-residential property (including mixed-use land and property) is also different. You’ll pay land tax on transactions over £150,000. This is currently 2% of the property value from £150,000 to £250,000 and 5% on the value above £250,000.

Joint ownership and stamp duty relief

If you’re a first-time buyer of a shared ownership home, you don’t have to pay stamp duty on the first £300,000 of value in a home that costs up to £500,000. This means all first-time buyers who invest up to £300,000 in their first home (shared ownership or otherwise) are now exempt from stamp duty. (4)
