This is simple patch that makes one of your membership level tax exempt when using US style taxing system. For version 3.4.x only.

Find this line in include/func.php in function func_calculate_singe

if ($product["free_tax"]=="N")

and replace it with

if (($product["free_tax"]=="N")&&($customer_info[membership] != 'Wholesale'))

This will make users who have membership named Wholesale tax exempt.

No user intreface (it will take much more modifications to make it a real end-user feature) and warrany of course, so use it at your own risk. Thanks.
