What is Stamp Duty Land Tax?
Stamp Duty Land Tax (SDLT) is a crucial tax for anyone investing in UK property. As a property investor, understanding investment property stamp duty is essential as it directly impacts your profitability. This tax applies to investment property stamp duty in England and Northern Ireland, payable on properties valued above a certain threshold. Keeping stamp duty on investment property in mind is vital when planning your investment strategy.
This guide will explain what Stamp Duty Land Tax is, detail the current investment property stamp duty rates, and clarify when you are legally required to pay it.
Understanding Investment Property Stamp Duty Rates in 2026
The amount of investment stamp duty you’ll pay depends on the property price and your investor status. It’s crucial to use an investment property stamp duty calculator to accurately forecast costs.
As of April 2025, the threshold for paying Stamp Duty Land Tax has changed. Properties priced at £125,000 and under are now exempt from SDLT. For properties priced above this, the tax is calculated in incremental bands, as seen below.
However, different charges are applicable for second homes and investment properties. Here are the Stamp Duty Land Tax rates for investment property from April 2025, assuming you already own property, meaning the additional surcharge applies:
| Property Value | SDLT Rate (including additional property surcharge) |
|---|---|
| Up to £125,000 | 5% |
| £125,001 to £250,000 | 7% |
| £250,001 to £925,000 | 10% |
| £925,001 to £1.5 million | 15% |
| Over £1.5 million | 17% |
Please note: These rates include the 5% additional property surcharge that typically applies to stamp duty for investment property. These rates were effective from April 2025.
Stamp Duty for Investors: Additional Properties and Overseas Buyers
If you’re scaling your property portfolio, the stamp duty for investors includes an additional 5% surcharge on top of the standard rates. This means the rates detailed above already incorporate this surcharge.
Overseas investor stamp duty is also a key consideration. If you are purchasing property as a non-resident, you will pay an additional 2% surcharge on top of all other applicable rates, including the additional property surcharge. Therefore, stamp duty for foreign investors can be significantly higher.
To summarise the surcharges:
- Additional Property Surcharge: 5% applies when purchasing additional residential properties.
- Non-Resident Surcharge: 2% applies to overseas buyers on top of all other SDLT charges.
For accurate calculations, especially when dealing with surcharges, using an investment property stamp duty calculator is highly recommended.
Do Overseas Investors Pay Stamp Duty Land Tax?
Yes, foreign investors are required to pay stamp duty on investment property in the UK. In fact, stamp duty for investors from overseas includes an additional 2% surcharge on top of the standard SDLT rates and the 5% additional property surcharge if applicable. This makes it crucial for foreign investor stamp duty calculations to be precise when considering UK property investments. This stamp duty on investment property for overseas buyers should be factored into any investment appraisal.
When Do You Pay Stamp Duty Land Tax?
It’s vital to know when investment stamp duty is due. You have 14 days from the date of property completion to pay SDLT. It is your legal responsibility to ensure timely payment to avoid penalties.
Who is Exempt from Paying Stamp Duty?
While stamp duty investment property is a significant consideration for most investors, there are some exemptions.
- First-time buyers: First-time buyers purchasing a property as their main residence may be exempt on properties up to £425,000, however, this threshold is reducing to £300,000 in April 2025.
- Other Exemptions: SDLT is not payable in situations such as property transfer due to inheritance, divorce, or for freehold properties purchased for £40,000 or less.
However, it’s important to remember that these exemptions are limited, and almost all investors considering stamp duty on investment property should factor this tax into their financial planning.
How to Pay Stamp Duty Land Tax
Typically, your solicitor or conveyancer will manage the complexities of stamp duty investment property. They will calculate your SDLT liability, collect the funds from you, and pay HMRC on your behalf, usually on the completion day.
If you are not using a solicitor or conveyancer for this, you are responsible for submitting an SDLT return to HMRC and paying within 14 days of completion.

Frequently Asked Questions
What are the Stamp Duty rates for investment property in 2026?
For investment properties or second homes, you must pay the standard SDLT rates plus a 5% surcharge (increased from 3% in late 2024). As of 2026, the first £125,000 of an investment property purchase is taxed at 5%, the portion between £125,001 and £250,000 at 7%, and the portion from £250,001 to £925,000 at 10%.
Do overseas investors pay more Stamp Duty in the UK?
Yes. Non-UK residents are subject to a 2% surcharge on top of all other applicable SDLT rates. If you are an overseas investor buying an additional residential property, your total surcharge will be 7% (5% for the additional property surcharge plus 2% for non-residency) added to the standard tax bands.
When is the deadline for paying Stamp Duty Land Tax?
You must file your SDLT return and pay any tax due within 14 days of the “effective date” of the transaction, which is almost always the day of completion. Failure to pay within this window results in automatic penalties and interest from HMRC.
Can I claim a refund if I sell my previous main residence later?
Yes. If you paid the 5% higher rate surcharge because you owned two properties at the time of completion, you can claim a refund if you sell your previous main residence within 3 years (36 months). You must apply for the refund within 12 months of selling that previous home.
Is Stamp Duty different for off-plan property investments?
Stamp Duty on off-plan property is calculated based on the purchase price at the time of completion, not when you reserve the unit. This means the tax is not due until the building is finished and the sale is finalised. However, you should budget for the rates expected at the future completion date.
