Understanding SDLT Relief: How to Avoid Overpaying on Property Transactions

Understanding SDLT Relief

When it comes to property deals, one of the biggest costs buyers often underestimate is Stamp Duty Land Tax (SDLT). Whether you’re purchasing your first home, investing in buy-to-let, or buying commercial premises for your business, SDLT can quickly become a major expense.

At Dunkley’s Accountants, we regularly provide tailored tax advice to help individuals and businesses structure property transactions efficiently and, where possible, claim valuable reliefs to reduce the bill.

 

 

Why SDLT Matters

 

SDLT is payable on most UK property and land transactions above a certain value. Rates vary depending on the type of property (residential, additional residential, or commercial) and the purchase price. For higher-value homes or portfolio landlords, SDLT can represent tens of thousands of pounds.

Errors are common, especially when rules change or where mixed-use property is involved. Paying too much can tie up cash unnecessarily, while paying too little can lead to HMRC penalties. Getting expert advice before completing a transaction ensures you know exactly what’s due, and whether reliefs apply.

 

 

Key SDLT Reliefs and Exemptions

 

There are still several reliefs available under the SDLT rules, but they can be complex. Common areas we advise on include:

  • First-time buyer relief – reducing the rate of SDLT on residential purchases up to a set threshold.
  • Mixed-use property rules – if a property includes both residential and commercial elements, SDLT may be charged at the lower non-residential rates.
  • Incorporation and partnership transfers – where property moves into a business or partnership structure, SDLT treatment can vary.
  • Group reliefs – for companies transferring property within the same group, potentially eliminating SDLT entirely.

Note: Multiple Dwellings Relief was abolished in June 2024, so it can no longer be claimed for new purchases.

It’s also important to remember that there is now a 5% surcharge (previously 3%) on most purchases of additional residential properties, such as second homes, buy-to-lets or properties bought through a company.

Each relief has strict eligibility criteria, and HMRC may challenge incorrect claims. Professional support helps ensure your position is clear and compliant.

 

 

Common SDLT Pitfalls

 

We often see clients surprised by the surcharge on second homes and buy-to-lets, or unsure whether a transaction counts as residential or mixed-use. Timing can also make a big difference, for example, selling a former main residence just outside HMRC’s grace period for replacing your home can mean paying thousands more than expected.
