Hi
Our tax structure for normal vatable purchase invoices as below
Example: Base Cost: = 100
VAT (15%) =15
Gross = 115
WHT (2% of base cost) =2
Net to be paid (115-2) =113
For some invoices, the tax law that obliges us not to record VAT (15% of base cost),so that we put the gross amount (115), BUT withholding should be calculated from the base cost.
How can I set the withholding parameter to calculate back to get the base cost ( mathematically => Gross amount/1.15)?
Thank you
