Ask HN: Calculating Destination-based Sales Tax Rates by Zip Code

  • As a small ecommerce player, I can't see why you would even bother doing this in any state other than the one in which you operate. I don't think Newegg does this, for example.

    BTW, I live in a zipcode with 2 cities that have different sales tax rates.

  • To further clarify, only need data on USA zip codes. Thanks in advance.
