FAQs

What is LTT?

Land Transaction Tax (LTT) is a tax payable to the Welsh Government when you buy or lease a property or land in Wales over a certain price.

It is the direct successor to the UK-wide Stamp Duty Land Tax (SDLT), which ceased to apply in Wales on 1 April 2018. While many people still instinctively use the term "Stamp Duty" when searching for property costs, LTT is a distinct tax governed by Welsh law and managed by the Welsh Revenue Authority (WRA).

Is Stamp Duty Wales free?

Reverse LTT is a specialist tool that allows you to work backwards from your available budget. While a standard calculator tells you how much tax you owe based on a property's price, the Reverse LTT tool tells you the maximum property price you can afford based on the specific amount of tax you have saved. This is particularly useful for buyers in the Welsh market who have a fixed "pot" of money set aside for moving costs and need to know their upper purchase limit.
