What Property Buyers Need to Know about SDLT
Stamp Duty Land Tax (SDLT), often referred to simply as Stamp Duty, is a key consideration when buying property in England and Northern Ireland. Understanding when it applies, how it is calculated, and what reliefs may be available can help you plan your purchase more effectively.
What is Stamp Duty Land Tax?
Stamp Duty Land Tax (SDLT) is a tax payable to HM Revenue & Customs (HMRC) when you buy property or land in England and Northern Ireland.
The amount of SDLT payable depends on several factors, including whether you are:
- a UK resident purchasing as an individual or company
- a first-time buyer
- replacing your main residence
- purchasing an additional property, such as a second home or buy-to-let
Stamp Duty is calculated on a tiered basis, based on the property’s purchase price, meaning you pay different rates on different portions of the purchase price rather than a single rate on the whole amount.
Current Stamp Duty thresholds and rates
Following the end of the temporary Stamp Duty relief on 31 March 2025, the standard SDLT thresholds now apply.
For a standard residential purchase where the buyer is a UK resident and replacing their main residence, the current rates are:
| Stamp Duty Thresholds from 1 April 2025 |
| 0% up to £125,000 |
| 2% from £125,001 to £250,000 |
| 5% from £250,001 to £925,000 |
| 10% from £925,001 to £1,5000,000 |
| 12% above £1,500,000 |
These thresholds apply regardless of whether the property is freehold or leasehold.
Stamp Duty for first time buyers
First-time buyers may be eligible for Stamp Duty relief, which can significantly reduce the amount payable.
| Stamp Duty Thresholds for First Time Buyers from 1 April 2025 |
| 0% up to £300,000 |
| 5% from £300,001 to £500,000 |
| Standard rates apply on properties above £500,000 |
Buying a second home or buy-to-let property
If you are purchasing an additional residential property, such as a second home or buy-to-let investment, higher rates of Stamp Duty usually apply.
In most cases, this means paying an additional 5% surcharge on top of the standard SDLT rates.
As a guide, the effective rates for additional properties are:
| Stamp Duty Thresholds for Second Homes and Buy-To-Let from 1 April 2025 |
| 5% up to £125,000 |
| 7% from £125,0010 to £250,000 |
| 10% from £250,0010 to £925,000 |
| 15% from £925,0010 to £1,5000,000 |
| 17% above £1,500,000 |
Different rules may apply to company purchases and certain reliefs may be available, for example for property development businesses.
When is Stamp Duty payable?
Stamp Duty liability is calculated based on the completion date, not the exchange of contracts.
This timing is particularly important for transactions that span periods when Stamp Duty rules or thresholds change. Even where contracts were exchanged, the SDLT position is determined by when the purchase completes.
As a general guide, residential conveyancing transactions often take around 12 weeks, although this cannot be guaranteed as it depends on factors such as finance, searches, the complexity of the property or the chain involved.
How much Stamp Duty will I need to pay?
The amount of Stamp Duty payable will depend on:
- the purchase price
- your buyer status
- whether any reliefs or surcharges apply
You can estimate how much Stamp Duty you may need to pay by using the SDLT calculator on the GOV.UK website.
