Sales Order Tax Implementation

How can I get this values from tax computation.
This is a sales invoice for a government contract
Amount Billed(AB): 1555000
VAT 12%
Expanded Tax(ET) (7%): 97187.5
ET = (AB/1.12) *.07
Amount Received(AR):1457812.5
AR = AB - ET

Every cent counts, so I need the result from the formula.

p.s.: im not an accounting person. :slight_smile:

Here’s the documentation, it has a video tutorial as well.
