The highest upfront cost when buying property in England or Northern Ireland is Stamp Duty Land Tax. Many buyers remain confused about how much stamp duty they need to pay, which rates apply, and how to calculate it correctly in advance of completing a purchase in 2025.
This guide describes the rates of UK Stamp Duty Land Tax rates for 2025/26, who pays it, any reliefs available, and how a Stamp Duty calculator can help anyone estimate the likely costs correctly in advance of purchasing a home or investment property.
What is Stamp Duty Land Tax (SDLT)?
Stamp Duty Land Tax (SDLT) is the tax paid when you buy:
- Residential property
- Buy-to-let property
- Commercial or mixed-use property
SDLT applies in England and Northern Ireland. (The use of different systems occurs in both Scotland and Wales.)
The tax is paid once, usually as part of the property purchase process, and has to be declared to HMRC shortly after completion.
Who pays Stamp Duty in the UK?
You usually have to pay Stamp Duty if:
- You buy a property above the SDLT threshold
- You purchase a second home or a buy-to-let property
- You are buying the property as an individual or a company
- You receive property in exchange for money or other value
First-time buyers and some buyers using reliefs pay reduced or zero SDLT.
UK Stamp Duty Rates 2025/26-Residential Property
Stamp duty is payable on a tiered basis, in that the percentage paid differs depending on the particular element of the price.
Standard Residential SDLT Rates
| Property Price Band | SDLT Rate |
|---|---|
| Up to £250,000 | 0% |
| £250,001 – £925,000 | 5% |
| £925,001 – £1.5 million | 10% |
| Over £1.5 million | 12% |
You pay only each rate against the portion of the price in that band, not the value of the entire property.
First-Time Buyer Stamp Duty Relief 2025
Stamp Duty relief may apply to first-time buyers, which will reduce or even eliminate the liability for SDLT.
If applicable:
- 0% on the first £425,000
- 5% on the portion between £425,001 and £625,000
- No relief if the property price exceeds £625,000
This will save thousands of pounds for first-time buyers.
Stamp Duty on Second Homes & Buy-to-Let Properties
If you're buying an additional residential property, a stamp duty surcharge applies.
Key takeaways:
- An additional 3% surcharge is payable in addition to the standard SDLT rates
- Applies to buy-to-let properties and second homes
- Applies even if the property is overseas
This creates a huge difference in the total stamp duty payable.
Stamp Duty for Non-UK Residents
Non-resident buyers of residential property in England and Northern Ireland pay:
- Standard SDLT rates
- Plus an additional 2% non-resident surcharge
This is even applicable in the case where the property purchased is done so as an investment.
Stamp Duty on Commercial Property
SDLT rules for commercial and mixed-use properties vary.
Commercial rates are normally lower and are calculated with different rules than those applied for residential. Always use a Stamp Duty calculator that supports commercial property to avoid errors.
How Stamp Duty Is Calculated
Stamp Duty is calculated using:
- Purchase price of the property
- Applicable SDLT thresholds
- Buyer status: first-time buyer, additional property, non-resident
- Applicable reliefs or surcharges
Because multiple rules can apply at once, manual calculations can be confusing.
