The Institute on Taxation and Economic Policy (ITEP), a non-profit, non-partisan research organization that works on federal, state, and local tax policy issues, just released the 5th edition of its annual assessment of the fairness of the state and local tax systems in all 50 states.  The assessment "discusses important features of each state’s tax system and includes detailed state-by-state profiles that provide essential baseline data to help lawmakers understand the effect tax reform proposals will have on constituents at all income levels." 

The ITEP study concludes that "every state fails the basic test of tax fairness… In other words, every single state and local tax system is regressive and even the states that do better than others have much room for improvement."
