Oklahoma has consistently taxed families with incomes below the poverty line. Oklahoma’s tax threshold for families of four has increased during the 1990s, but a substantial gap remains between the threshold and the poverty line. Taxes on a family of four with poverty-level income increased between 1994 and 1999. In 1991, a family of four owed tax when its income exceeded 72 percent of the poverty line. For 1999, Oklahoma’s tax threshold is 75 percent of the poverty line.
