You can calculate the new "Welsh Stamp Duty" (Land Transaction Tax) using this page's Land Transaction Tax calculator.

At this point the Land Transaction Tax calculations on this page are confined to residential, freehold property transactions undertaken by a private individual (as opposed to a company).

You can use the Quick Calculator on this page to work out LTT due on such transactions and, via the toggle switch on the widget, compare it with the old SDLT.

Finally, if you need to calculate SDLT or Scottish LBTT - either quickly (common conditions) or in detail - visit the Home Page of this website.



Switch between LTT & SDLT


* Assumes that the transaction is residential and freehold, and that the buyer is a private individual.

LTT compared with SDLT

All of the graphs below refer to standard residential rates, with the transactions being undertaken by private individuals.

As the transaction price is split up into the various bands it transcends and the stamp duty rate for each respective band is applied to the amount of the transaction price within each band, an overall de facto stamp rate emerges for any given transaction price, as shown in the graph below.

The actual stamp tax due for any given transaction price is plotted below.
