Rule reference

BR-Z-06 The document level allowance at allowances[0] uses VAT category Z (Zero rated), so its VAT rate (BT-96) must be 0 (zero), but it is 19

The document level allowance at allowances[0] uses VAT category Z (Zero rated), so its VAT rate (BT-96) must be 0 (zero), but it is 19. Zero rated means the rate is zero — that is the whole content of the category. Any other value here would put VAT on an adjustment to a supply the document has just declared untaxed, and would split the breakdown into two Z groups, which BR-Z-01 forbids.

This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.

The fix

Set allowances[0].vatRate to 0, or omit it — this library normalises the rate for category Z either way. If you did mean to charge 19% VAT on this allowance, the category should be S instead, and that will change which breakdown group it nets into.
