You're pretty close with the tax table setup. The 'Tax Group' is meant to be a broader description, such as Australian tax group or Canadian tax group, etc. Within each tax group, the jurisdictions are related to the specific types of taxes, such as GST, Provincial Sales tax, city tax etc.

Also, the Tax descriptions would be something to the effect of 'Taxable Fees', 'Non-taxable Fees', 'GST only Taxable Fees', Taxable Disbursements', etc.

Thus, when you edit the Tax table jurisdictions to enter the rates, you will see all of the descriptions appear for fees and disbursements, and you can enter the appropriate percentages. If you follow the examples I gave above for descriptions, you would enter 10% for the descriptions 'Taxable' and 'GST only taxable', and 0 for 'Non taxable'. The same goes for any other type of tax you have.

Lastly, your setup of minimum and maximum taxes is correct (a zero maximum implies no maximum tax). You could always enter an amount of 9,999,999.99 for a maximum tax if required. The Taxable? yes/no field determines whether or not the tax is itself taxable. IE if you have 2 taxes and one should calculate tax on the other, then in the setup, the first jurisdiction you define should be the 'taxable tax', and you set the Taxable? option to Yes. If you only have a GST tax, then this field is not necessary and should be set to No.

Make sure your tax rate was saved properly in the table, as it could have been left as 99.999%. This is the only place where tax maintenance is performed, so when this is complete, you are ready to go. Hope this helps out.
