DotNetNuke does have data built in to associate States/Provinces (Regions) with Countries. When I go to Admin > User Accounts, I can edit a user's profile and select a Country. If I select "United States", the Region field changes from a textbox to a drop-down list of States. If I select "Canada" the Region drop-down shows a list of Provinces. If I select "France" the Region drop-down shows a list of Departments.
This hierarchy does exist in DNN. It just may not be in the place you're currently referencing. However, it may not be that difficult to modify the tax features to use the data that is already in DNN. What do you think?
