How Sales Tax & GST Calculations Work
Add GST Mode: Calculates sales tax on top of a net base price.
GST Amount = Amount × (Rate / 100)
Final Price = Amount + GST Amount
Remove GST Mode: Extracts the base price and embedded tax from a tax-inclusive price.
Base Price = Amount / (1 + Rate / 100)
GST Amount = Amount - Base Price
