If I'm buying a buy-to-let property in 2026 as my second home, can I still claim Stamp Duty Land Tax (SDLT) relief or exemptions, or will these be phased out by then?
Quick Answer
No, from 2026 you cannot claim SDLT relief or exemptions when buying a buy-to-let as a second home. The 5% additional dwelling surcharge for second properties continues to apply.
## Will I get SDLT relief on a buy-to-let in 2026?
No, from 2026, you will not receive specific Stamp Duty Land Tax (SDLT) relief or general exemptions when purchasing a buy-to-let property as a second home. The current SDLT framework, which includes an additional dwelling surcharge, is expected to remain in place. For residential properties, the standard SDLT rates are 0% on the first £125,000, 2% on £125,000-£250,000, 5% on £250,000-£925,000, 10% on £925,000-£1.5 million, and 12% on anything over £1.5 million. On top of these, a 5% additional dwelling surcharge has applied to second properties since April 2025.
## What are the current additional dwelling SDLT rates?
The additional dwelling surcharge for second homes and buy-to-let properties is 5% on the entire purchase price, levied on top of the standard residential SDLT rates. This means that for a second property or BTL purchase, the effective rates start at 5% for properties up to £125,000. For example, a £200,000 buy-to-let property would incur standard SDLT at 2% on the £75,000 above £125,000 (i.e., £1,500), plus the 5% additional dwelling surcharge on the full £200,000 (i.e., £10,000), totalling £11,500 in SDLT. This substantially increases the upfront cost of acquiring investment properties.
## Can first-time buyer relief be used for a buy-to-let?
First-time buyer relief cannot be used for a buy-to-let property, as it is specifically designed for individuals purchasing their main residence. This relief allows eligible first-time buyers to pay £0 in SDLT on the first £300,000, and 5% on the portion between £300,000 and £500,000, provided the total property value does not exceed £500,000. Since a buy-to-let is an investment and not a main residence, it does not qualify, regardless of the buyer's first-time buyer status for their primary home. The 5% additional dwelling surcharge will still apply to a first-time buyer if the BTL purchase means they effectively own more than one property.
## How does the 5% additional dwelling surcharge impact investment costs?
The 5% additional dwelling surcharge significantly increases the initial capital outlay for property investors, influencing cash flow and overall investment viability. For an investor purchasing a £300,000 buy-to-let property, the SDLT calculation would involve the standard rates plus the 5% surcharge. Specifically, this would be 5% on the first £125,000 (£6,250), 7% (2% + 5%) on the next £125,000 (£8,750), and 10% (5% + 5%) on the remaining £50,000 (£5,000), totalling £20,000. This adds a substantial cost, affecting the initial return on investment and requiring investors to have higher liquid capital available for property acquisitions. Planning for this 'landlord tax' is crucial when calculating BTL investment returns and overall profitability.
## Are there any scenarios where the 5% surcharge might not apply?
The 5% additional dwelling surcharge generally applies to most purchases of additional residential properties. However, there are limited exceptions. If you are replacing your main residence and sell your previous main home within three years of purchasing your new one, you can claim a refund of the surcharge. The surcharge also typically doesn't apply to commercial properties, but buy-to-lets are classified as residential. Additionally, some specific types of dwellings, such as caravans, houseboats, or properties not considered 'dwellings', might be exempt from SDLT entirely, though these are not typical buy-to-let investments. Always check HMRC guidance or consult a tax specialist for specific circumstances.
Steven's Take
The SDLT landscape has become significantly less forgiving for property investors. Since April 2025, the 5% additional dwelling surcharge is a constant factor in buy-to-let purchases. This means an investor looking at a £250,000 property, which previously might have had a lower SDLT bill, is now paying an additional £12,500 just due to this surcharge. You must factor this into your financial modelling and evaluate how it impacts your net initial yield and cash flow. Don't rely on 'phasing out' of taxes; assume the current, harsher regime is here to stay, and build your strategy around it for BTL investment returns.
