VAT totals have opposite signs

ErrorPeppol BIS 3.0BT-110BT-111

Also available in:NederlandsFrançais

What it means

The VAT total in invoice currency and the VAT total in accounting currency must have the same sign. Currency conversion must not turn a charge into a credit or vice versa.

Typical causes

  • Currency conversion reversed the sign.
  • A credit note total was copied with the wrong sign.

How to fix it

  1. Check the VAT total and whether it represents a charge or credit.
  2. Correct the converted VAT total so its sign agrees.
  3. Check the exchange-rate calculation before exporting again.
What the rule says (technical)

Invoice total VAT amount and Invoice total VAT amount in accounting currency MUST have the same operational sign.

Make both tax totals either positive or negative.
