Stamp Duty Land Tax (SDLT): Everything You Need to Know

When you buy a property in the UK you also have to pay a buying tax, Stamp Duty. It is likely to be your single biggest buying expense; exactly how much it will set you back will depend on its price and your circumstances.

You may also come across other taxes further down the line – such as Capital Gains Tax w hen selling, or Inheritance Tax when passing a property on. 

The size of the property tax burden is such that it pays to get the right advice early. At Black Brick, we can introduce you to leading independent tax specialists in London, so you have a clear picture before you commit.

Alongside any advice, you can also find everything you need to know about Stamp Duty below.

What Is Stamp Duty?

Although the name dates back to 1684, when the monarchy levied a tax on postage stamps to help pay for a war with France, Stamp Duty in its modern incarnation as a property-buying tax, is a relatively new phenomenon.

Officially called Stamp Duty Land Tax (SDLT), it is a tax on property purchases in England and Northern Ireland (Wales and Scotland have their own systems) and was introduced in December 2003.

Stamp Duty rates have been tinkered with, usually in an upward direction, many times since then and will differ depending on whether you are buying a primary home, a second home or buy-to-let property, or if you are an international buyer –  we cover the details in the sections below.

Stamp Duty Rates and Thresholds

Stamp Duty can be hard to understand, because instead of being chargeable at a flat rate on the total price of your property it is charged in bands. Each band attracts a different Stamp Duty rate, and you pay that rate on the proportion of your property’s value that falls within that band. 

There’s no cap on Stamp Duty – the higher the property price, the more Stamp Duty you pay. And the same rules also apply whether the property is freehold or leasehold.

When to pay SDLT

Stamp Duty must be paid to the HMRC (His Majesty’s Revenue and Customs), the official UK Government department responsible for collecting taxes, within 14 days of a sale being completed. 

When you work with Black Brick, we’ll help arrange this to make sure you make the correct payment at the correct time. 

Stamp Duty for second home owners and international buyers

Second home owners, including those buying a rental or investment property, must pay a five per cent surcharge on the basic Stamp Duty rates.

This means that while a domestic buyer’s primary residence worth £1m will attract a Stamp Duty bill of 4%, equivalent to £43,750, a second home of the same value will result in a bill of 9.4% which is £93,750.00. 

International buyers must also pay a further surcharge of two per cent. This means that buying a £1m primary residence will cost 6.4% equivalent to £63,750 in tax, and buying a £1m second home will cost 11.4% equivalent to £113,750 in tax.

What happens if you buy a property with a UK resident partner?

If a property is purchased jointly with a partner, friend, or relative, the non-UK surcharge applies if just one of buyers is a non-resident. 

Are there any exceptions to these Stamp Duty prices?

There are different, lower, Stamp Duty rates at play for domestic first time buyers. You will also pay less if you buy a non-residential, mixed use property, or make multiple-property purchases. This could include assets like commercial buildings, agricultural land, a shop with an apartment above it, or a block of six or more flats. 

Rates start at 0 per cent on the first £150,000 of the property’s price, two per cent on its cost from £150,001 to £250,000, and five per cent on anything above that. And there are no extra surcharges. Camilla Dell, Managing Partner at Black Brick explains, “Buying multiple properties has become a popular strategy for many of our investment clients who like the idea of owning 6 or properties and paying significantly lower rates of stamp duty. Recent examples of how we have assisted investors include the purchase of this freehold block of 7 apartments in South Kensington SW7 sourced for an overseas investor client looking for wealth diversification and long term capital growth.” 

The other exception is if a property is being bought through a company, for £500,000 or more. In these deals Stamp Duty is charged at a flat 17 per cent on the entire purchase price. And there may be tax relief options too. Black Brick’s trusted contact list of financial and tax experts can offer detailed advice on this kind of purchase, including whether any tax relief might be available.

You will also need specialist advice if you plan to buy shares of a company that already owns a property, rather than buying the property directly. This could exempt you from Stamp Duty but involves significant other legal and tax implications. 

What happens if I pay the second home Stamp Duty surcharge and then quickly sell my main home?

You may be able to reclaim some Stamp Duty if you bought the property as a second home but sell your main residence within 36 months. Applications must be submitted to HMRC within 12 months of either selling your previous home or submitting the Stamp Duty return for your new property – whichever happens later.

Why Stamp Duty Matters

When Stamp Duty rates change, which seems to happen regularly, the market reacts. The temporary Stamp Duty holiday, which was introduced during the pandemic to boost the housing market, triggered a short-lived boom in the market and rising prices – even though the maximum tax saving available was a modest £15,000.

On the flip side of the coin, an increase in Stamp Duty costs can trigger a downturn in the market and often unintended consequences too. The introduction of the surcharge for second homes has led to a decline both in buyers picking up holiday homes for themselves and investing in rental properties too. This has led to a reduction in the number of rental homes available, and as a result residential rents have spiralled.

Are there any future tax changes on the cards?

Stamp Duty is regularly used by politicians to manipulate the housing market, and to raise cash.

There is certainly impetus behind a wholesale reform of the tax. In June 2027 the influential Housing, Communities and Local Government (HCLG) Committee published a report recommending the Government examine alternative systems.

Exactly what direction those alternative arrangements will take depends on which party wins the next General Election. The Conservative Party’s flagship policy is to entirely abolish the tax on primary residences, claiming the move will stimulate housing market mobility, help young buyers, and encourage older people to downsize.

The incoming Labour leader, Andy Burnham, is also thought to favour abolishing Stamp Duty. He is known to support replacing both Stamp Duty and Council Tax with a new land value tax (LVT) levied at 0.48 per cent of a property’s value per year.
