FAQ
- How is tax extracted from a tax-inclusive (gross) amount?
- Net = Gross / (1 + rate / 100). The tax portion is then Gross minus Net. This is the standard reverse-calculation used when a price already includes tax.
- What is the difference between "Add Tax" and "Remove Tax" modes?
- "Add Tax" starts from a pre-tax (net) price and calculates how much tax to add. "Remove Tax" starts from a tax-inclusive (gross) price and backs out how much tax is embedded in it.
