Remove tax from a total
Net price = gross total / (1 + Consumption tax rate / 100). The tax amount is the gross total minus the net price.
120 at 20% becomes 100 + 20
If the total is 120 and the tax rate is 20%, the pre-tax amount is 100 and the tax amount is 20.
Use the exact rate
Some countries, states, provinces, and products use reduced or combined rates. Change the rate when your invoice uses a different one.
