Can you write a report that only highlights the transactions on a particular tax code within specified dates?

Hello Useraccounts37, 

Welcome to the Community page, 

So you can have a look at the report called VAT detail report, this will show you all the transactions that have vat codes against them, but there is no way to get it to just show a certain vat code. You can edit the date range at the top so it just shows you the transactions with vat codes on in that specific time frame.
