Did a project the other day for a client who wanted a Buy to Let stamp duty calculator. Which got me thinking. If you want to do the calculation there are loads of sites that do it for you but none of them have it all in one place. So I built a plugin that works in England and NI, Scotland and Wales and covers FTB, Standard rates and BTL. Seems to work OK Is there anything missing? https://variants.loanpaymentplugin.com/uk-stamp-duty/ One thing I thought about adding was a table underneath the result showing the different rates.
