It's not what you earn, it's what you keep that often dictates your standard of living. With that in mind, take this quick tour of the ten cities in the nation that have the lowest overall tax burden. These cities came out on top (er, at the bottom, really) of the latest District of Columbia survey of state and local taxes that fall on citizens in the largest city in each of the 50 states and D.C. We chose the lowest-tax cities for two-income couples earning $75,000 with one school age child. The national median tax bite for such families is 9.1% going to state and local revenuers. For these cities, the range is from 4.1% to 6.7%. The property tax figure shown for each city is based on the estimated value of a hypothetical home that a couple earning $75,000 would own: the auto tax figure assumes the couple owns two cars and is based on the estimated registration fees, state and local gasoline taxes, and personal property taxes, if any.
