• VAT code is 0% but VAT amount is not 0
• VAT code is not 0% but VAT amount is 0
• Calculated VAT amount does not match the entered VAT amount
• VAT amount ≥ amount excl. VAT, while 'tax explanation code' is not set to 'VT'
• VAT amount ≠ invoice amount, while 'tax explanation code' is set to 'VT'

When does this validation not fail?

Additional information

What do the amounts mean?

• Invoice amount = invoice amount incl. VAT - credit limit.
• Actual VAT amount = VAT amount set on the invoice (may be the VAT amount on the VAT lines)
• Amount excl. VAT = invoice amount - specific VAT amount*
• Specific VAT amount* = calculated VAT using (gross) invoice amount and VAT percentage, thereby a specific calculation with the gross amount instead of the net amount.
• If the invoice amount is 0, the actual VAT amount is used.
• Calculated VAT amount = amount excl. VAT * VAT percentage
