A category's VAT amount does not match its base and rate
For each breakdown line, the VAT category tax amount (BT-117) must equal the taxable amount (BT-116) multiplied by the rate (BT-119) divided by one hundred, rounded to two decimals.
A financial field: the expected value is computed and offered, never written into the document — the correction is the issuer's to make. Test your invoice to find out whether it is affected.
The message your validator prints
Copied verbatim from the sealed artefact: this is the exact sentence the check prints when this rule fails.
[BR-CO-17]-VAT category tax amount (BT-117) = VAT category taxable amount (BT-116) x (VAT category rate (BT-119) / 100), rounded to two decimals.

These phrases mirror what an integrator searches for: code, syntax, rule, business field and correction.
Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
Why this error happens
The rule mandates rounding the result to two decimals, and that is where implementations diverge: rounded per line then summed, or summed then rounded, the two do not give the same cent. The rounding mode matters too — banker's rounding and half-up part ways on halves.
How to fix it
Fix the calculation in the system that produced the invoice, not in the file. Factlint computes the expected value and returns it in `suggested_value`, but never writes the field.
