BR-S-09: VAT amount wrong for category "S"
This code shows up when an electronic invoice is validated. Here is what it means, why it fires, and what to change in the file.
Why this code appears
For category S (standard rate), the VAT amount declared is not the taxable amount multiplied by the rate. VAT at the standard rate is computed on the base: an amount that does not match the declared rate has the invoice rejected.
How to fix it
Recalculate the amount from the base and rate written in the SAME breakdown, then round to the cent. One- or two-cent gaps almost always come from a total computed line by line and then added up, instead of computed on the aggregated base.
What it looks like in the file
These two snippets are replayed against our own checker on a complete invoice, every time the site is built. The first one raises this code, the second one does not.
What raises the code:
<ram:CalculatedAmount>150.00</ram:CalculatedAmount>What to write instead:
<ram:CalculatedAmount>200.00</ram:CalculatedAmount>Where it happens
This code comes from EN 16931, the European e-invoicing standard. It concerns business term BT-117.
