Warning

CII-DT-044: Do not use a discount or charge basis amount in VAT information

In short

Warning: worth checking.

CII-DT-044 warns that a tax element in your CII file contains AllowanceChargeBasisAmount. Remove that element from the tax information, without removing your discounts or charges.

What it means

The rule checks every ram element whose name ends in TradeTax and warns if it has a direct ram:AllowanceChargeBasisAmount child.

Why it matters

Discounts and charges have their own invoice fields. This rule excludes the additional basis amount from tax information; it does not tell you to change the discounts, charges or taxable amounts.

How to fix it

Delete ram:AllowanceChargeBasisAmount from each affected tax element. Keep your discounts and charges in their designated fields. If your invoicing software adds the element, ask its supplier to correct the CII export, then generate and check a new file.

Once the file is corrected, check it again for free: Validate an invoice against EN 16931
