UK: local authorities charge a property tax based on the value of homes determined some time ago. The amount raised is insufficient to cover costs so central government provide a 'revenue support grant' to each of the local authorities in the UK country in question. That money comes from income tax which is paid to the central government in the UK. The formula used to calculate the level of revenue support changes, some would say that the changes are politically based. My feeling is that, given the robust politics that appears to exist in the US, coupled with what again appears to be frequent recourse to litigation between levels of government, you don't want to go down that route.
