Tax Laws


In July of 1862, Congress passed the Internal Revenue Act to provide income for the Government to pay the public debt including Civil War costs. After the Civil War, taxes were abolished until only a tax on liquor and tobacco remained in 1883. An 1895 Supreme Court ruling declared that income tax was unconstitutional and led to the ratification of the sixteenth amendment in 1913 which states that Congress has the power to establish and collect taxes on incomes. This was the beginning of our modern day taxes.

What history has shown us is that while property taxes are locally levied, there is significant state involvement with the amount of tax local political subdivisions can levy, how property assessments are conducted, and what services local taxing subdivisions must provide for their residents. Many of the changes the state has made in the past to lower the local property tax required a shift in financial responsibility from the local governments to the state. This comes at a cost to state taxpayers, because the state has obligations it must fund as well, with a limited amount of state tax dollars.
