Stamp Duty Land Tax (SDLT) Calculator
SDLT in England and Northern Ireland operates on a progressive, marginal slice system. The 3% surcharge for additional properties creates significant friction for buy-to-let investors.
Understanding the 3% Surcharge
The 3% surcharge applies if, at the end of the day of the transaction, you own two or more residential properties and have not replaced your main residence. It applies to the entire purchase price, severely impacting the viability of lower-yield investments.
