Regarding Paris-hometown hoppers, I am not against keeping up connections to the hometown -- to the contrary, I think it would be better for them if they'd get not only people's vote but taxes too.

Regarding the tax collecting/distributing system, then it seems it is not much different from what we have here. Here, one of the two main tax sources of local authorities is a fixed percentage of the income tax of its registered inhabitants (which, as in France, the tax authority collects but then redistributes to local authorities according to residence registration data).
