I have a number of EU supplier invoices to process, some have decided to pay duty/VAT at port some we have set up a HMRC VAT/Duty deferment account.

What is the correct T VAT code to use to submit the invoices where we have paid duty at port? And what code should I use for the invoices where we have used the HMRC deferred VAT/Duty account?

If I use T19, which the Sage tax code finder tells me to use it is adding 20% VAT onto the cost of the incoive therefore overtstating the invoice and supplier account balance?

Do you use T18 for the invoices where I have deferred the VAT/duty?

Also how does the HMRC deferment statement work with regards VAT return processing?
