Are there any specific relief or exemption scenarios for the 3% second home SDLT surcharge that might be introduced or withdrawn in the 2026 fiscal year for landlords selling their primary residence to buy two investment properties?
Quick Answer
The additional dwelling SDLT surcharge is 5% as of April 2025, not 3%. There are no current reliefs for landlords selling a primary residence to buy two investment properties, meaning the 5% surcharge likely applies to both purchases.
## Understanding SDLT for Multiple Investment Property Purchases
As of April 2025, the additional dwelling Stamp Duty Land Tax (SDLT) surcharge for England and Northern Ireland is 5%, not 3%. There are no specific relief or exemption scenarios currently announced for the 2026 fiscal year that would allow landlords selling their primary residence to avoid this surcharge when buying *two* investment properties. The primary residence rules dictate that if you are selling your main home and buying another main home, you typically avoid the surcharge. However, when acquiring two investment properties, neither purchase qualifies as replacing your main residence. The 5% surcharge applies when purchasing an additional residential property if, at the end of the day of the transaction, you own two or more residential properties. This applies whether the properties are intended as buy-to-lets or other forms of secondary residences. The key factor is whether the property being acquired is replacing your main residence *and* if you are selling your previous main residence within a specific timeframe, usually three years.
### How the 5% SDLT Surcharge Applies to Investment Properties
The 5% additional dwelling surcharge for SDLT is levied on top of the standard residential rates. This means that for a £250,000 investment property, the SDLT breakdown would be 0% on the first £125,000, 2% (plus 5%) on the next £125,000 (up to £250,000), and so on up the SDLT bands. Specifically, this calculates as 0% for the initial £125,000, then 7% (2% standard + 5% surcharge) for the portion between £125,000 and £250,000. These figures align with the current SDLT thresholds, where the standard residential rates are 0% up to £125,000, 2% for £125,000 to £250,000, 5% for £250,000 to £925,000, 10% for £925,000 to £1.5M, and 12% above £1.5M. The surcharge makes acquiring multiple properties significantly more expensive. For instance, a £300,000 investment property would incur £1,500 in standard SDLT (5% of £300,000) if no other properties were owned, but with the 5% surcharge, it becomes £16,500 (5% on £125,000-£250,000 i.e. 7% of £125,000 + 10% of £50,000). The current rules do not offer a blanket exemption for landlords re-investing the proceeds from a primary residence sale into multiple investment properties.
### Specific Scenarios for SDLT Surcharge Calculation
**Scenario 1: Selling a main residence and buying two investment properties simultaneously.** If a landlord sells their primary residence for £400,000 and uses the proceeds to purchase two investment properties, each valued at £200,000, the 5% additional dwelling surcharge would apply to both £200,000 properties. Neither property is replacing the main residence, as two properties are being acquired. This results in standard SDLT plus the 5% surcharge on each investment property. For a £200,000 property, the standard SDLT is £1,500 (2% of £75,000). With the 5% surcharge, it becomes £5,250 (7% of £75,000) for each property, totalling £10,500 in additional SDLT not including the first £125,000 which is 0%. These are significant added costs for investors looking to expand their portfolio from a main home sale.
**Scenario 2: Replacing a main residence with a new main residence, then buying an investment property.** If the landlord sold their £400,000 main residence and purchased a new main residence for £350,000, then subsequently bought a £200,000 investment property, the SDLT for the new main residence would *not* include the 5% surcharge. However, the subsequent £200,000 investment property *would* be subject to the 5% surcharge, as it is an additional dwelling. This demonstrates the criteria for main residence replacement.
**Scenario 3: Exemption for bulk purchase of multiple dwellings.** There is a 'multiple dwellings relief' which applies when two or more dwellings are purchased in a single transaction or as part of a series of linked transactions. While this can sometimes reduce the overall SDLT liability by calculating the tax based on the average value of the dwellings, it does not remove the 5% additional dwelling surcharge where applicable. For investors buying multiple properties, particularly those looking into buy-to-let investment returns, it is essential to understand these nuances. The relief, if applicable, still sees the 5% surcharge added to the reduced calculation meaning it still adds a significant amount to the purchase cost and impacts landlord profit margins.
## Potential Future Changes to SDLT
While there are no specific announcements for 2026 regarding changes to the 5% additional dwelling surcharge, SDLT rules are subject to review by the government. The abolition of Section 21 expected in 2025, alongside Awaab's Law, indicates a focus on tenant protection and housing standards, rather than landlord tax relief. Investors should monitor government announcements through official channels like HMRC and HM Treasury for any updates. The current regulatory environment focuses on ensuring fair housing and maintaining revenue streams, rather than providing new tax exemptions for multiple property acquisitions. The focus on residential property tax, including Capital Gains Tax with its reduced annual exempt amount of £3,000, suggests a continued interest in revenue generation from property transactions.
### The importance of professional advice on SDLT
Navigating the complexities of SDLT, especially when dealing with multiple property transactions, requires careful planning. Professional advice from a qualified property tax accountant can clarify how the current 5% additional dwelling surcharge applies to your specific circumstances, including any potential benefits from the multiple dwellings relief. Understanding the total purchase costs, including SDLT, is critical for accurate rental yield calculations and overall investment viability. This becomes even more pertinent for investors considering various BTL investment returns strategies and portfolio expansion.
## Investor Rule of Thumb
Unless directly replacing your primary residence with another main home, assume the 5% additional dwelling SDLT surcharge will apply to any subsequent residential property purchase, significantly increasing your acquisition costs.

Steven's Take
The question of SDLT relief for landlords buying two investment properties after selling their main home comes up often. It’s crucial to understand that from April 2025, the additional dwelling surcharge is 5%, not 3%. The rules are designed to apply this surcharge if you own more than one residential property at the end of the transaction day, unless the newly purchased property is replacing your primary residence. When buying two investment properties, neither is classified as replacing your main home, so the 5% surcharge will likely apply to both. There are no current indications for 2026 that this policy will change or that new specific reliefs will be introduced for this scenario. Always factor in this significant extra cost when doing your due diligence and calculating your overall investment profitability.
