Kansas Income Tax Calculator
Kansas income tax is calculated on your taxable income after deductions and exemptions. This calculator estimates your Kansas state income tax liability for the current tax year. Enter your annual gross income, choose your filing status (single, married filing jointly, married filing separately, or head of household), and add any pre-tax deductions to see your estimated state tax, effective tax rate, and marginal bracket. Results update in real time as you adjust your inputs. The calculator covers Kansas state income tax only; federal income tax, FICA payroll taxes, and any local income taxes your city or county imposes are separate. All rates and brackets are sourced directly from Kansas Department of Revenue and are verified for the current tax year. Use this tool alongside the federal income tax calculator to see your combined total tax liability. Effective rate and marginal rate are both shown so you can evaluate the impact of additional income, filing status changes, or increased pre-tax contributions to a 401(k) or similar plan.
Kansas uses graduated income tax brackets. A single filer earning $60,000 owes $2,731.09 in state income tax, an effective rate of 4.55% and a marginal rate of 5.58%. Enter your own income and filing status below.
