35. Stamp Duty and Land Tax Declaration

The Stamp Duty Land Tax (SDLT) Declaration, often referred to simply as the Stamp Duty Declaration, is a legal document required in property transactions in the United Kingdom. It is used to declare and pay the Stamp Duty Land Tax, a tax levied on property purchases in England, Wales, and Northern Ireland. 


The SDLT Declaration is typically completed by the buyer's solicitor or conveyancer and submitted to HM Revenue & Customs (HMRC) following the completion of a property purchase. It provides details about the property transaction, including the purchase price, any exemptions or reliefs that may apply, and the amount of Stamp Duty Land Tax payable. 


The Stamp Duty Land Tax is calculated based on the purchase price of the property and the prevailing SDLT rates set by the government. Different SDLT rates apply depending on factors such as the value of the property, whether the buyer is a first-time buyer, and whether the property is residential or commercial. 


Once the SDLT Declaration is submitted and the Stamp Duty Land Tax is paid, HMRC issues a Stamp Duty Certificate, which serves as evidence that the tax has been paid and the property transaction is legally recognised. 


The SDLT Declaration is a crucial document in property transactions in the UK, as it ensures compliance with tax laws and regulations governing property purchases and helps facilitate the transfer of ownership from the seller to the buyer. 


Stamp Duty and Land Tax Declaration: Key questions  

Is the property moveable (e.g., a mobile home, caravan, or houseboat)? 


Moveable properties like mobile homes, caravans, and houseboats are generally exempt from SDLT because they are not considered permanent fixtures on land. 


  • Impact: If the property is moveable, the buyer will not be liable to pay SDLT, potentially reducing the overall cost of the purchase. 

Will the property be a mixture of residential and non-residential? 


Properties that are a mixture of residential and non-residential (e.g., a shop with a flat above it) may be subject to different SDLT rates compared to purely residential properties. 


  • Impact: The SDLT rate and calculation can differ, often resulting in a lower tax bill than a purely residential property. Buyers should be aware of these classifications to accurately estimate their tax liability. 

Whether bought, gifted, or inherited, has the buyer(s) ever owned any residential property or land anywhere in the world? 


This question determines if the buyer is considered a first-time buyer or if they might be subject to additional SDLT surcharges. 


  • Impact: Buyers who have previously owned residential property may not qualify for first-time buyer relief, leading to higher SDLT. Additionally, those purchasing additional properties may face a 3% surcharge on top of standard rates. 

After this purchase has completed, will the buyer(s) and their spouses or civil partners own more than one property worth more than £40,000? 


This question assesses whether the buyer will own multiple properties post-purchase, which can trigger the additional 3% SDLT surcharge for second homes. 


  • Impact: If the buyer or their spouse/civil partner will own more than one property, they will be subject to higher SDLT rates, significantly increasing the overall cost of the purchase. 

Will the property be the main residence for the buyer(s)? 


SDLT rates can vary based on whether the property will be the buyer’s main residence or an additional property. 


  • Impact: If the property will be the buyer's main residence, they may qualify for standard SDLT rates. Conversely, if it is not the main residence, higher rates or surcharges may apply, affecting the financial planning for the purchase. 

Are the buyer(s) UK residents? 


SDLT rates and surcharges can differ for UK residents versus non-residents. Recent changes have introduced additional surcharges for non-residents buying residential property. 


  • Impact: Non-UK residents may face an additional 2% surcharge on top of the standard SDLT rates, increasing the overall purchase cost. UK residents generally avoid this surcharge, making the tax implications less severe. 

Understanding these questions and their implications is crucial for buyers to accurately estimate their Stamp Duty Land Tax liability and plan their property purchase accordingly. Misinterpretations or oversights in these areas can lead to unexpected tax bills, impacting the affordability and financial strategy of the property acquisition. Consulting with a conveyancer or tax advisor can help navigate these complexities and ensure compliance with SDLT regulations. 


How is Stamp Duty Land Tax (SDLT) Calculated? 


Stamp Duty Land Tax (SDLT) is a tax levied on property and land transactions in England and Northern Ireland. The amount of SDLT you pay depends on several factors, including the property price, whether it is residential or non-residential, and your status as a buyer.  


Here's a detailed explanation of how SDLT is calculated: 

SDLT rates for residential properties 

SDLT for residential properties is calculated using a tiered rate system, where different portions of the property price are taxed at different rates. As of the most recent guidelines, the rates are as follows: 

  • Up to £250,000: 0% 
  • £250,001 to £925,000: 5% 
  • £925,001 to £1,500,000: 10% 
  • Above £1,500,000: 12% 

SDLT rates for first-time buyers 

First-time buyers purchasing properties up to £500,000 may benefit from relief, reducing their SDLT liability: 

  • Up to £425,000: 0% 
  • £425,001 to £625,000: 5% 
  • Above £625,000: Standard rates apply (no relief) 

SDLT surcharges for additional properties 

If you are purchasing an additional residential property, such as a second home or a buy-to-let, an extra 3% surcharge applies to each SDLT band. 

SDLT for non-residential and mixed-use properties 

The rates for non-residential and mixed-use properties (those that have both residential and commercial elements) are different and generally lower than residential rates: 

  • Up to £150,000: 0% 
  • £150,001 to £250,000: 2% 
  • Above £250,000: 5% 

Factors affecting SDLT calculation 


  • Non-UK residents: Additional 2% surcharge for non-UK residents buying residential property. 
  • First-time buyers: Possible reliefs up to a certain threshold. 
  • Shared ownership: Special rules apply for shared ownership properties. 
  • Multiple dwellings relief: Available for purchases of multiple properties in a single transaction. 

SDLT is calculated based on the property's purchase price, the type of property, and the buyer's circumstances. Understanding the tiered rate system and potential surcharges is crucial for accurately determining your SDLT liability. It is often advisable to consult with a conveyancer or tax advisor to ensure you fully understand and comply with SDLT requirements.
