How a national tax affect local and state revenues?

A national tax can impact local and state revenues by potentially reducing the overall tax base available for state and local governments. If a national tax is perceived to replace or diminish the need for certain local or state taxes, it may lead to decreased revenue for those jurisdictions. Additionally, if the national tax is redistributed back to states, it can create dependency or shifts in local funding priorities. However, the overall effect depends on the structure of the national tax and how it interacts with existing state and local tax systems.
