Why does SDLT
Overpayment Occur?

Every year thousands of people overpay SDLT either through the misclassification of their property or a simple lack of awareness of the numerous exemptions and reliefs available.

HMRC’s SDLT calculator is commonly used to calculate the rate payable, yet it only provides a guide figure, and it does not consider the many reliefs available, nor variables in the transaction itself.

For many solicitors, mortgage advisors and individuals HMRC’s calculator is the main tool used to calculate SDLT rates, resulting in 1 in 4 calculations being incorrect. In some cases, it’s possible to achieve up to 80% reduction in Stamp Duty costs.
