Tax Calculation after Address Input, Multiple Tax Options

[KimonoLab]

So, I ran a couple online stores with PrestaShop back in the day, and I remember there being many problems with getting taxes to function properly. I fixed the tax problems back then, and it looks like these are new ones, or that PS made the problems permanent and unfixable.

Does anyone know how to:

1. Have the cart not add tax until after the customer inputs their address (so it adds taxes only if the customer's order is taxable).

2. Have multiple options for taxes (such as taxes in specific states and specific countries, and not for anyone else).

 

Currently, I can only have it so tax displays for everyone but disappears after the customer inputs their non-taxable address, or not have any taxes on my website at all.
