Are there any rumoured exemptions or reliefs for new build second homes or properties used for short-term lets that might come into effect with 2025 stamp duty changes?
Quick Answer
As of December 2025, there are no official rumours or confirmed exemptions for new build second homes or properties used for short-term lets regarding the upcoming 5% additional dwelling SDLT surcharge.
## Will New Build Second Homes or Short-Term Lets Get SDLT Exemptions in 2025?
As of August 2026, there are no specific announced exemptions or reliefs from the additional 5% Stamp Duty Land Tax (SDLT) surcharge for new build second homes or properties intended for short-term lets. The existing additional dwelling surcharge of 5% applies across all residential property value bands when purchasing a second home or buy-to-let, irrespective of whether it's a new build or an existing property. This means that a new build property costing, for example, £300,000, would incur 5% SDLT on the first £125,000, 7% on the portion between £125,000 and £250,000, and 10% on the remaining portion above £250,000, all due to the surcharge. The government has not indicated any changes that would specifically benefit these types of properties for SDLT purposes in 2025 or beyond.
### What About Council Tax Premiums for Second Homes and Short-Term Lets?
From April 2025, local councils in England have the power to charge a Council Tax premium of up to 100% on furnished second homes. This can effectively double the annual Council Tax bill. For short-term lets, the situation is more nuanced. If a property is genuinely available to let for 140 days or more per year and actually let for 70 days or more per year, it may qualify for business rates instead of Council Tax. This is a crucial distinction, as properties falling under business rates are not subject to the second homes Council Tax premium. However, it's important to note that this is at the discretion of individual local councils, and investors must check their specific council's policy and criteria for these rules.
### Does This Affect All Properties Similarly?
Not all properties are affected in the same way. The additional dwelling SDLT surcharge applies strictly to residential properties that are not the buyer's only or main residence. For example, a new build apartment purchased as a second home will incur the surcharge. However, a property classified as 'mixed-use' – such as a ground-floor shop with a flat above – is treated as commercial property for SDLT purposes. This classification can lead to a significantly lower SDLT bill, as commercial rates are 0% up to £150,000, 2% between £150,000 and £250,000, and 5% above £250,000. This avoids the 5% additional dwelling surcharge entirely, presenting a potential tax efficiency for certain property types that contain both residential and commercial elements.
### Scenarios for SDLT and Council Tax Impact
1. **New Build Second Home**: A new build residential property purchased for £400,000 as a second home would incur SDLT at the additional dwelling rates: 5% on the first £125k (£6,250), 7% on £125k-£250k (£8,750), and 10% on £250k-£400k (£15,000). Total SDLT: £30,000. If its standard Council Tax was £2,000, from April 2025 it could become £4,000 if the council applies the full 100% premium.
2. **Short-Term Let (Residential)**: A property used for short-term letting, if not meeting the business rates criteria, would be subject to the standard residential SDLT rates with the 5% surcharge and could also be liable for the Council Tax second home premium. If it qualifies for business rates, it would avoid the Council Tax premium, but SDLT would still be at the residential additional dwelling rate on purchase.
3. **Mixed-Use Property**: A property valued at £400,000 with a shop on the ground floor and a flat above would be subject to commercial SDLT rates: 0% up to £150k (£0), 2% between £150k and £250k (£2,000), and 5% on £250k-£400k (£7,500). Total SDLT: £9,500. This illustrates a substantial saving compared to the residential second home scenario, as it avoids the 5% additional dwelling surcharge and the higher residential base rates.
## Potential Considerations for Investors
* **Commercial vs. Residential SDLT**: Understanding the distinction between commercial and residential property for SDLT is critical, especially for properties with mixed-use potential. Mixed-use properties are treated as commercial for SDLT purposes.
* **Business Rates for Holiday Lets**: Properties available for short-term let for 140+ days per year and actually let for 70+ days may qualify for business rates, exempting them from Council Tax and associated premiums. Investors must confirm local council policies.
* **Local Council Discretion**: The application of the Council Tax premium for second homes is discretionary for each local council. Checking the specific policies of the relevant local authority is essential for accurate financial forecasting.
## Investor Rule of Thumb
Always assume the most conservative tax treatment for new property acquisitions; if any reliefs or exemptions materialise, they represent an upside rather than a correction to a flawed initial projection.
## What This Means For You
With increased holding costs from potential Council Tax premiums and the ongoing SDLT surcharge, accurate financial modelling is more vital than ever. Understanding how these regulations impact different property types, such as new builds or mixed-use assets, is key to making profitable decisions.

Steven's Take
The market rumour mill often generates hope for tax breaks, but as seasoned investors, we must always deal in facts. There's no concrete evidence of specific SDLT exemptions coming for new build second homes or short-term lets. The 5% additional dwelling surcharge has been firmly in place, and government focus tends to be on increasing housing supply for owner-occupiers, not reducing taxes for second property owners. For Council Tax, the shift for second homes from April 2025 is a real cost increase, potentially doubling bills. The only existing 'relief' for short-term lets is the business rates pathway, which requires specific criteria to be met and is council-dependent. For SDLT, mixed-use properties continue to offer a more favourable tax treatment on acquisition compared to pure residential second homes. Always calculate your numbers based on the current, known rules.
What You Can Do Next
1. Review the latest government guidance on SDLT for residential and mixed-use properties via gov.uk/stamp-duty-land-tax, to understand applicable rates for your specific property type.
2. Check the specific local council's website where your target property is located for their Council Tax policy on second homes and short-term lets, especially regarding the April 2025 premium and business rates eligibility.
3. Obtain a professional SDLT calculation from a solicitor or tax advisor for any potential acquisition, particularly for mixed-use properties, to confirm the correct classification and liability.
4. For potential short-term lets, verify the business rates criteria and process with the local Valuation Office Agency (VOA) or a specialist business rates consultant to confirm qualification and potential savings.
