I have released an update to v2.0 for the woocommerce tax rate plugin to work with woocommerce 2.0. I have also added a few new features that allow you to see how many zip codes rates you are using, and how many rates per state you are using. Also added a feature that allows you to change the “Tax” title that shows up on the checkout page.

 

If you update to the latest woocommerce which you should always keep your plugins up to date, it will erase all of your old zip code rates so you will need to download this new version install it, and add your csv files again.
