Charge only one tax from resellers

[fraso]

I see that the Dual Pricing - Wholesale Pricing download (modified with Harmeet's changes) allows a customer to be set up as a wholesale customer who is tax-exempt. However, the Tax Exemption Status download seems to do something similar.

I would like to set my store up as follows:

• retail prices shown to the general public.
• wholesale prices shown only to wholesale customers once they have logged-in.
• wholesale customers are exempt from paying provincial retail sales tax once they provide their tax exemption number.
• quantity-based discounts for wholesale customers and possibly also for retail customers.

What would be the best way to accomplish this?
