Bottom Line
Kansas has progressive income tax rates from 3.1% to 5.7%. The state is excellent for public sector retirees — fully exempting Social Security (under $75,000 AGI), government pensions, and military retirement. However, the small standard deduction ($3,500 single), high sales tax (up to 11%), and above-average property tax (1.37%) create a higher overall tax burden. Private sector retirees may find better options in neighboring states like Texas or Missouri.
