VAT, GST, and sales tax formulas
The same simple formulas work for many tax systems when you already know the correct tax rate.
Tax exclusive formula
Tax Amount = Base Amount x Tax Rate / 100
Total Amount = Base Amount + Tax Amount
Tax inclusive formula
Base Amount = Inclusive Total x 100 / (100 + Tax Rate)
Tax Amount = Inclusive Total - Base Amount
