Multi-tier Jurisdictions
Many countries that impose tax have subdivisions or subsidiary jurisdictions that also impose tax. This feature is not unique to federal systems, like the U.S., Switzerland and Australia, but rather is a common feature of national systems. The top tier system may impose restrictions on both the ability of the lower tier system to levy tax as well as how certain aspects of such lower tier system work, including the granting of tax exemptions. The restrictions may be imposed directly on the lower jurisdiction's power to levy tax or indirectly by regulating tax effects of the exemption at the upper tier.
