Calculates Canadian sales taxes: GST HST and PST today or as they were in the past.

Java Applet that can also be run as an application.

This version computes by adding GST HST and PST to a base
price. It also works in reverse given the
final price working backwards to get the taxes and base
price. In other words, it will tell you the sticker
price to make something come out even after taxes are added.

You can compute taxes as they were on past or future dates.
It computes nickel rounding to account for the withdrawal of the penny.
