If you are buying a property with a partner who already owns another residential property, higher rate Stamp Duty Land Tax (SDLT) rules may apply.
Even if you personally do not own property, you may still be treated as purchasing an additional property depending on how the ownership is structured.
How Joint Purchases Are Assessed
HMRC assesses stamp duty liability based on the combined position of all buyers.
If one buyer owns another residential property and is not replacing their main residence, the 3% higher rate surcharge can apply to the entire purchase.
Example Scenario
If you are a first-time buyer but your partner already owns a buy-to-let property, the transaction may be treated as an additional property purchase.
In that case, the higher rate of SDLT could apply, even though one buyer has never owned property before.
Can You Avoid the Higher Rate?
The higher rate may not apply if the property being purchased replaces a main residence and the previous home is sold within the allowed timeframe.
Ownership structure, marriage status, and timing can all affect the outcome.
