SDLT Calculator for Buy-to-Let/Additional Property Purchases

Table of Contents

Stamp Duty Land Tax (SDLT) is applicable when purchasing a freehold, leasehold or shared ownership residential property in England. Since 3 December 2014, buy-to-let property and additional residential property purchases have attracted a Stamp Duty Land Tax (‘SDLT’) surcharge of 3% for acquisitions above £40,000.

If you are just moving to a new house whilst selling your old house, then this surcharge does not apply and SDLT is calculated in accordance with the rules applicable to main residential property purchases – see our SDLT calculator for main residential properties.
