HI @Valerie212
the tax will be your plan around times the tax rate of the province where your phone number located
and if you use autopay , you don't really need to worry
if you try to load up money, you just enter the plan amount and PM will add tax on top, ie, if your plan is $25, just enter 25 and PM will add tax with your credit card
if you try to buy voucher, buy the plan amount voucher and let the tax added at the cashier, ie, ask the cashier for a $25 voucher if your plan is $25, the cashier will then add tax on top.
