Kansas
Social Security benefits are exempt from any Kansas income tax for its residents, as long as they have a federal adjusted gross income of $75,000 or less. For taxpayers with a federal AGI above this number, Social Security benefits will be taxed by Kansas at the same level they are taxed by the feds.
The income tax range is low in Kansas, as low as 3.1% (on $2,501 to $15,000 of taxable income for single retirees and %5,001 to $30,000 for joint filers), and as high as 5.7% (on more than $30,000 of taxable income for single filers and more than $60,000 for joint filers).
