We need a simple Federal income tax---so I outline one in this link. Let regions, states, and localities tinker with their own systems as they see fit. High cost, overly bureaucratic places will suffer while forward looking ones will thrive. This plan likely will collect more revenue than our existing system and it will have many indirect benefits including letting low income earners understand that government does cost them money, whether they feel it directly or not. In later posts, I will explain how we can close the deficit by changing the "business model" of government, to bring down its cost.
