Entering all US taxes?

hello everyone,

client would like to have different taxes apply depending on state. Hmmm… I heard it slows down your site and browser hiccup. Any best practices?
Thank you!

I assume you are talking about sales taxes. There are thousands of different taxing jurisdictions in the United States. There can also be special taxing areas within taxing jurisdictions. There are services that can be subscribed to that track taxes in the different jurisdictions. But it is not cheap. accuratetax.com is one such service and there are others.
