What about the reverse tax calculation?

To be able to do a reverse calculation GST and QST, you have to consider the amount with taxes and split it at the combined rate of 1.14975. The original amount not including the two taxes is then obtained. To obtain the amount of GST, multiply the amount without taxes obtained by 5%. On the other hand, to get the amount of the QST, multiply the amount without taxes by 9.975%.

Note that a margin of error of $ 0.01 is accepted, as rounding of amounts is necessary to facilitate the calculation.
