Yes it can be added through dashboard on admin/settings/taxes/US we can overrride tax and can select collection.
Doesnt it mean we can add tax on collection ?
Once this is added how do I retreive it using rest API ? We can find tax in each state through country.json but this does not show overriden tax.
Cool.. never saw that before... neat. The API is never in lockstep with things you can do with the Admin, so I would not be holding my breath over finding a way to deal with taxes and collections via the API.
