How to apply different Sales Tax rates to the same Membership Type  Back Office
In Canada we need to charge Sales Tax depending on what Province the Member resides in. How can we do this in the Back Office [i.e. administrator signing up a Member in CiviCRM].
You can do this with Price Sets. I'll document the entire set up:
Go to Administer > CiviContribute > CiviContribute Component Settings
and check the box Enable Tax & Invoicing (Tax = Sales Tax; Invoicing you get as a bonus)
Go to Administer > CiviContribute > Financial Accounts
and create one Financial Account for each Sales Tax Rate
Ignore TaxDeductible  it is not related to Sales Tax; it potentially could be used to track whether monies are deductible for Income Tax purposes but I don't recommend it [there are other ways to track that; will document that at some point]. Click Is Tax > (Tax = Sales Tax) and enter the Tax Rate right below it.
Repeat until you have the 3 Financial Accounts needed (3 different Sales Tax rates):
Set up Financial Types > And associate each

Set up Financial Types > And associate each one with a one of the Financial Accounts we just created. Note we can add a 4th one [for out of Country residents]  i.e. with no Sales Tax.
Next are Price Sets  create a Price Set  for each
