When we use the codes for VAT Reverse charge on an invoice why is the VAT summary not shown at the bottom like other standard rated invoices?

Hello Accounts442, 

Welcome to the Community page, 

So CIS Reverse Charge will not show on the invoice, you as the customer must put a disclaimer on the bottom of the invoice if you have a look at this link here in section 14 it tells you all about it. So on the invoice in the section that says message on invoice is where you put the legal words in that area you will need to put how much the VAT would of been, as the VAT will not show as normal.
