EN 16931
FATAL
This is a VAT category rule for Standard rate VAT. When any line, allowance or charge uses this category, the standard requires a matching, internally consistent VAT breakdown (seller identifiers, category rates, taxable and tax amounts).
How to fix it
- Check every line using this VAT category against the requirement in the rule text.
- Make sure the VAT breakdown (BG-23) contains exactly one entry for this category, with consistent rate and amounts.
- For exemption-style categories, provide the exemption reason text or code where required.
Official rule text
An Invoice that contains an Invoice line (BG-25), a Document level allowance (BG-20) or a Document level charge (BG-21) where the VAT category code (BT-151, BT-95 or BT-102) is "Standard rated" shall contain in the VAT breakdown (BG-23) at least one VAT category code (BT-118) equal with "Standard rated".
