Buying a property in the UK is a major financial decision that involves careful planning, legal procedures, and tax obligations. One of the most important taxes payable on property purchases in England and Northern Ireland is Stamp Duty Land Tax (SDLT).

Whether you are a first time buyer, a homeowner moving up the ladder, or a property investor expanding your portfolio, understanding how SDLT works in 2026 is essential. With updated thresholds in force since 1 April 2025 and no further rate changes confirmed in the 2025 Autumn Budget, knowing your liability helps you avoid unexpected costs and stay compliant with HMRC.

What is Stamp Duty Land Tax (SDLT)?

Stamp Duty Land Tax is a tax charged by HMRC on the purchase of property or land in England and Northern Ireland. It applies when the purchase price exceeds the nil rate threshold and is calculated using a tiered (progressive) system based on the value of the property.

Different property taxes apply elsewhere in the UK. Buyers in Scotland pay Land and Buildings Transaction Tax (LBTT), while buyers in Wales pay Land Transaction Tax (LTT). Each operates under its own thresholds and rates.

What Transactions Are Subject to SDLT?

SDLT applies to a broad range of property transactions, including:

• Freehold property purchases
• Leasehold property acquisitions (new or assigned)
• Properties bought using cash or a mortgage
• Shared ownership scheme purchases
• Transfers of land or property interests with chargeable consideration
• Lease assignments and the grant of new leases

The tax is triggered when a chargeable interest in land is acquired in England or Northern Ireland.

When is SDLT Payable?

SDLT becomes payable when the transaction is completed or substantially performed. This may occur when:

• Legal ownership of the property is transferred
• The buyer takes possession of the property
• A significant portion of the purchase price has been paid

The SDLT return must be filed and any tax due paid to HMRC within 14 days of completion. Missing this deadline can result in penalties and interest charges.

What is SDLT Charged On?

SDLT is calculated on the chargeable consideration, which is typically the purchase price paid for the property. However, chargeable consideration may also include non cash elements such as:

• Assumption of an existing mortgage
• Property exchanges or part exchanges
• Goods, services, or works carried out
• Other forms of value transferred between buyer and seller

How is SDLT Calculated in 2026?

SDLT is calculated using a progressive band system, where each portion of the property price is taxed at a different rate. The current rates have been in place since 1 April 2025 and remain in effect throughout 2026, with no further changes announced in the 2025 Autumn Budget.

Standard SDLT Rates for Main Residence (2026)

Worked example: On a £500,000 main residence, you pay 0% on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the remaining £250,000 (£12,500), totalling £15,000 in SDLT.

SDLT on Additional Properties (Second Homes and Buy to Let)

If you buy an additional residential property such as a second home, holiday home, or buy to let, a 5% surcharge applies on top of standard SDLT rates. This rate increased from 3% to 5% on 31 October 2024 (Autumn Budget 2024) and remains in force throughout 2026.

SDLT Rates for Additional Properties (2026)

The surcharge applies to the entire purchase price and is triggered if any one of the joint buyers already owns another residential property worth £40,000 or more anywhere in the world. Married couples and civil partners living together are treated as a single unit for these purposes.

Refund opportunity: If you sell your previous main residence within 36 months of buying the new one, you may reclaim the 5% surcharge from HMRC.

SDLT for Companies and Corporate Buyers

Limited companies and other non natural persons buying residential property in England or Northern Ireland are subject to specific rules:

• A flat 17% SDLT rate applies to residential properties costing more than £500,000 purchased by companies, partnerships with corporate members, and collective investment schemes (increased from 15% on 31 October 2024).
• For purchases at or below £500,000, companies pay standard rates plus the 5% additional property surcharge automatically, regardless of whether they own other properties.

Some reliefs may apply, for example where the property is used for a qualifying property rental business or development.

SDLT and Joint Ownership

When buying property jointly, SDLT is assessed based on the combined circumstances of all buyers. If any one buyer owns another residential property worth £40,000 or more, the higher rates apply to the entire transaction, not just their share.

First Time Buyer Relief in 2026

First time buyers in England and Northern Ireland can claim SDLT relief, but the thresholds were reduced on 1 April 2025 and continue to apply in 2026.

• 0% SDLT on properties up to £300,000
• 5% SDLT on the portion between £300,001 and £500,000
• No relief is available on properties over £500,000 (standard rates apply to the full price)

To qualify, all buyers must be purchasing their first ever residential property anywhere in the world and must intend to live in it as their main home.

SDLT Surcharge for Non UK Residents

Non UK residents buying residential property in England or Northern Ireland pay an additional 2% surcharge on top of all other applicable SDLT rates. This means an overseas buyer purchasing an additional property could pay up to 19% at the top band (12% standard + 5% additional property + 2% non resident).

You are classed as non resident for SDLT purposes if you have not been present in the UK for at least 183 days in the 12 months before completion.

SDLT on Leasehold Properties

For leasehold property purchases, SDLT may be payable on:

• The lease premium (the upfront price paid for the lease), using standard SDLT rates
• The net present value (NPV) of future rent payments, charged at 1% on the portion above £125,000

This dual calculation makes leasehold SDLT more complex than freehold transactions and often benefits from professional review.

SDLT Exemptions and Reliefs

There are situations where SDLT may not apply or can be reduced:

• Property transfers under a court order during divorce or separation
• Gifts of property where no consideration (including mortgage debt) changes hands
• Transfers between companies in the same corporate group
• Transfers to registered charities for charitable purposes
• Purchases below the £125,000 nil rate threshold
• Group relief, charities relief, and certain other statutory reliefs

Important update: Multiple Dwellings Relief (MDR) was abolished on 1 June 2024. It is no longer available for transactions completing on or after that date, except in limited transitional cases where contracts were exchanged on or before 6 March 2024.

Each relief depends on specific conditions, and professional advice is strongly recommended.

How to Pay SDLT

The SDLT return must be submitted to HMRC and the tax paid within 14 days of completion. In most cases, your solicitor or conveyancer will handle this process on your behalf, often collecting the funds before completion.

Late filing or payment may trigger penalties starting from £100, plus daily interest. Once HMRC has processed the return, they issue an SDLT5 certificate, which is required to register your ownership with the Land Registry.

When is SDLT Not Payable?

SDLT is generally not payable in the following situations:

• Property inherited under a will, where no additional consideration is given
• Gifts of property where no mortgage is taken on or transferred
• Certain transfers between spouses or civil partners following divorce or separation, made under a court order
• Transactions where the chargeable consideration falls below the nil rate threshold

However, if a mortgage is assumed or any consideration is exchanged, SDLT may still apply on the value transferred.

Conclusion

Stamp Duty Land Tax remains one of the most significant upfront costs in any UK property transaction. With the lower thresholds introduced on 1 April 2025 still in effect throughout 2026, most buyers in England and Northern Ireland are paying more SDLT than during the 2022 to 2025 temporary relief period.

Understanding how SDLT is calculated, when it applies, and which reliefs you qualify for can lead to meaningful savings. Given the complexity of the rules around surcharges, reliefs, and refunds, seeking professional advice from a specialist property tax adviser is the best way to ensure compliance and optimise your tax position.
