Payables Invoice Interface - supply tax line

Summary:

Stop Invoice Validation creating a tax line for specific source only

Content (required):

All our invoice interfaces supply the item line(s) and tax is created at Invoice Validation. We have a requirement for a new interface to supply the tax line. Is there a flag that will suppress tax creation at validation or is it a setting with tax setup ?
