Neither the Jesuits nor the Indians pay property taxes. Hence this “donation” which happens to benefit another party who’s behind the scenes. Jesuits do not give away real estate for mere altruism.
If the property is converted to Indian territory, then right, they wouldn’t pay taxes. But my prior comment in that conversation was that I don’t think the Jesuit’s donation does convert that property, in which case barring any exemption that relates to the owners (ie a church) as opposed to the land (ie territory), then I think they would pay taxes like anyone else ... I think.
