Poll taxes in the United States is the history of the use of poll tax (tax of a fixed sum on every liable individual, without reference to income or resources) across the US. Poll taxes had been a major source of government funding among the colonies and states which formed the United States. Poll taxes became a tool of disenfranchisement in the South during Jim Crow, following the end of Reconstruction. This persisted until court action, following the ratification of the 24th Amendment in 1964, ended the practice.
