FX-SCH-A-000522: Use an allowed tax type code for an invoice charge

In short

Error: fails the selected checks.

FX-SCH-A-000522 means the tax type code for a charge on the whole invoice (BG-21) is not allowed. For VAT, use VAT in ram:CategoryTradeTax/ram:TypeCode within the charge, then export and recheck your file.

What it means

In the Basic profiles of Factur-X and ZUGFeRD, this rule checks a non-empty ram:TypeCode inside the charge's ram:CategoryTradeTax against the permitted tax type codes. It applies to charges identified by ram:ChargeIndicator/udt:Indicator equal to true. An empty value passes this particular test; the rule does not check whether the element is present.

Why it matters

The tax type identifies which tax the charge's category refers to. It is separate from the VAT category and the VAT rate.

How to fix it

Check the tax type exported for the charge on the whole invoice. For VAT, ram:CategoryTradeTax/ram:TypeCode must contain VAT in capitals, not a percentage or a local tax abbreviation. Keep the VAT category and rate appropriate to the charge. If your software writes an invalid code, report this rule id to its supplier, then export and recheck.
