Oklahoma Personal Income Tax Laws

States often have personal income tax, in addition to the federal income tax. The revenues from these state income taxes typically fund necessary parts of state government, from K-12 schools and Medicaid to jails and highways. Failing to pay your taxes, including state income taxes, can have serious consequences, including professional license non-renewal. For more information, see FindLaw's tax evasion article.
