BR-CO-17 VAT per rate rounded wrongly
The VAT of a rate (BT-117) must be that rate's taxable amount (BT-116) times the rate, rounded to two decimals.
The rule's official text
VAT category tax amount (BT-117) = VAT category taxable amount (BT-116) x (VAT category rate (BT-119) / 100), rounded to two decimals.
An error: the validator rejects the invoice, and recipients may refuse it.
What usually causes it
- VAT was rounded per line and added up, which drifts by a cent.
- The taxable amount includes allowances or charges, but the VAT was computed without them.
How to fix it
- Compute the VAT once per rate from the sum of that rate's lines (minus allowances, plus charges) and round only then.
- Then check BR-S-08 and BR-CO-14, which depend on the same amounts.
