What is HST and how do I manually calculate reverse taxes?

HST stands for Harmonized Sales Tax, which is a combination of the federal GST (5%) and a provincial sales tax (PST) into a single unified tax. The current HST rate in New Brunswick is 15%, consisting of the federal portion (5%) and the provincial portion (10%).

Reverse HST calculations allow you to find the pre-tax selling price from an amount that already includes HST. This is done using a formula or an automated calculator that extracts the HST and the pre-tax amount from the total including tax.

The general formula for the reverse calculation of HST is:

Initial amount = Amount including HST ÷ (1 + HST rate)

For example, if you have a payment of $452 (HST included), you can use the reverse tax calculation to determine the amount excluding tax.

We get:
Amount including HST = $452
HST rate = 15% = 0.15

Using the above formula, we have:

Initial Amount = $452 ÷ (1 + 0.15)

Initial Amount = $ 393.04

To find the HST amount:

HST Amount = HST Included Amount – Initial Amount

HST Amount = $452 – $ 393 = $ 58.96
