Oklahoma's progressive tax applies marginal rates to each bracket of income. The state uses federal adjusted gross income as the starting point with Oklahoma-specific modifications. Oklahoma offers a standard deduction and personal exemption. The state fully exempts Social Security benefits from taxation.
