What is Stamp Duty Land Tax (SDLT)?

The Stamp Duty Land Tax (SDLT), or stamp duty, is the tax that you have to pay when you buy a property in England and Northern Ireland. In Scotland, the same kind of tax is called the Land and Buildings Transaction Tax (LBTT). And for Wales, it is called the Land Transaction Tax (LTT).

How to use our Stamp Duty Land Tax calculator?

Our Stamp Duty Land Tax calculator is straightforward and very easy to use. By following the four steps below, you will be able to calculate the stamp duty you need to pay for your property purchase:

  1. Identify the buyer type:

    Firstly, you will identify whether you are one of the following:

    • First-time buyer
    • Moving home
    • Buying an additional property
    • Buying the property to let or flip

    Different buyer types will have different stamp duty rates and stamp duty thresholds.

  2. Choose your residency:

    Next, you need to identify yourself as either a UK resident or a Non-UK resident. Non-UK residents are required to pay more stamp duty.

  3. Determine your property price:

    Then, you will need to know the price of the property you plan to purchase.

  4. Understand your stamp duty

    Well, you should now be able to see how much stamp duty you need to pay for your property purchase. Stamp duty tends to be one of the highest costs when buying a property, so make sure you check it thoroughly before deciding.

How does the stamp duty calculation work?

The Stamp Duty Land Tax calculation is not too complicated, but it is not overly simple either. Before we dive any deeper, let's look at the following table and understand the standard stamp duty thresholds and stamp duty rates:

Property Price

Stamp duty rate

Up to £250,000


£250,001 – £925,000


£925,000 – £1.5 million


Over £1.5 million


The stamp duty calculation follows the principles below:

  • If you are a non-UK resident, all your standard stamp duty rates will increase by 2%. For instance, instead of paying 5% from £250,001 to £925,000, you will need to pay the stamp duty at 7%.

  • If you are buying an additional property, either to live in, to rent out, or to flip, you will need to pay 3% more. For example, you will need to pay at the stamp duty rate of 8% for property valued from £250,001 to £925,000.

  • And, if you are both non-UK resident and are buying additional properties, you will need to pay 2% + 3% = 5% more than the standard rate. Additionally, for a property valued above £250,000, you will need to pay 10%.

  • However, there is one exception -- the first-time buyer stamp duty. If you are a first-time buyer buying a property below £625,000, you don't need to pay any stamp duty for the first £425,000 and 5% for the rest. For instance, if you buy a property for £450,000, you will only need to pay £25,000 * 5% = £1,250 for the first-time buyer stamp duty.


What is buy-to-let stamp duty?

Buy-to-let stamp duty is the stamp duty you have to pay when investing in a property and planning to rent it out to other people. The stamp duty rates for buy-to-let properties are higher than the standard stamp duty rates.

Is the stamp duty in Scotland and Wales the same as the rest of the UK?

The stamp duty only applies to England and Northern Ireland. For stamp duty in Scotland, it is called the Land and Buildings Transaction Tax (LBTT). And for Wales, it is called the Land Transaction Tax (LTT).

Can the stamp duty be negative?

No, the capital gains tax cannot be negative as this means that the government will be paying you money.

What is the stamp duty holiday?

Stamp duty holiday is a policy introduced during the pandemic to combat low economic activities. It allows people in England and Northern Ireland to purchase property without paying any stamp duty on properties up to £500,000. This scheme was effective until 30th June 2021.

What factors affect your stamp duty?

The amount of stamp duty that you have to pay is based on the following factors:

  • Buying intentions, buy-to-let buyers need to pay higher stamp duty;
  • Investor type, resident outside of the UK, needs to pay higher stamp duty; and
  • Property price: The higher the property price, the higher the stamp duty applied.
