Hi Nathan,

Which version of the Cart and DNN are you currently running?

1) Yes, I believe you are on the right track, utilizing the Tax Tables option should suit your needs although currently the ability to specify tax rates per Country is not currently supported.

Actually you only need to fill in City and State in the Smtih_Tax table. The Cart will lookup tax rate based on the ship to state/province and city entered by the customer. If you want to calculate tax based only on the zipcode then only populate the xip in the tax table and the cart will lookup tax only based on the zipcode the user enters.

SmithCart also supports the ability to calculate tax by tax districts using the tab table method. In the Cart Settings under the Tax Setup section is a feature titled “Use Step1 Dropdown List in Tax Lookup”. If “Use Step1 Dropdown List in Tax Lookup” is checked then the cart will lookup tax in the tax table based state and tax district (county). The custom dropdown in step 1 becomes required based on the states selected in the taxable state list in the buynow settings.

Or if you have budget in your project and would like to be provided with a fixed quote to sponsor a portion of the cost to develop the ability to specify the Country in the Tax Tables, please send an email with a link to this post to sales@smith-consulting.com. We quote all feature enhancements below cost since it is enhancing the module and in most cases we can start work within a week.

2) I recommend using the Custom Ship Methods By Weight option. Choosing this option will allow you to set a Shipping Zone for each Shipping Method.

Hope this helps!
