Kansas income tax calculator 2026 – how it works
Kansas imposes a state individual income tax with marginal rates that apply to Kansas taxable income. Under the current statutory structure, Kansas uses a two-bracket structure for individuals. For filers who are not married filing jointly, the first bracket applies a 5.2% rate on Kansas taxable income up to 23,000, and the second bracket applies a 5.58% rate on taxable income above 23,000. The rate change is described in official Kansas guidance and is tied to the amended statutory rate language. This calculator focuses on estimating the state income tax that results from applying the marginal rates to taxable income. The marginal structure means the higher rate applies only to the portion of taxable income above the threshold, not to the full amount. In practical terms, the first 23,000 is taxed at 5.2%, and only the income above 23,000 is taxed at 5.58% for the supported filing model. Official authority: Kansas Department of Revenue. Rate changes and the effective “current and subsequent tax years” language are documented in Kansas Department of Revenue Notice 24-08.
Examples
Example 1 (Kansas taxable income: 20,000). Because 20,000 is within the first bracket, the estimated Kansas tax is 5.2% of 20,000. That produces an estimated tax of 1,040. Example 2 (Kansas taxable income: 23,000). At the bracket threshold, the estimated Kansas tax is 5.2% of 23,000. That produces an estimated tax of 1,196. Example 3 (Kansas taxable income: 60,000). The first 23,000 is taxed at 5.2% (estimated 1,196). The remaining 37,000 (60,000 minus 23,000) is taxed at 5.58% (estimated 2,064.60). The total estimated Kansas tax is 3,260.60. These examples illustrate how the marginal rates apply to slices of taxable income. The calculation model used here matches the standard marginal-bracket computation implied by the official bracket threshold and rates for the supported filing model.
Limitations and important notes
This estimate is limited to a single calculation model: individuals who are not married filing jointly. Kansas publishes separate thresholds and a base-tax amount for married individuals filing joint returns, and that joint-filer model is not supported in the calculator’s calculation logic. This calculator estimates tax on Kansas taxable income. It does not compute Kansas taxable income from federal adjusted gross income, Kansas additions and subtractions, itemized deductions, standard deduction, exemption allowances, or other Kansas-specific adjustments. Those inputs can materially change the taxable income amount used for the bracket calculation. Kansas income tax law includes definitions, special rules, and administrative guidance that may affect individual circumstances, including residency status and other state adjustments. For authoritative details, rely on official Kansas Department of Revenue publications and the controlling Kansas statute as amended under the current statutory framework.

FAQs about Kansas income tax calculator 2026
What Kansas income tax rates apply?
Kansas uses the individual income tax rate structure that applies under the current statutory structure. For filers who are not married filing jointly, the rates are 5.2% up to 23,000 of Kansas taxable income and 5.58% above 23,000. The official change and effective-year language are documented by the Kansas Department of Revenue in Notice 24-08.
Does Kansas have different income tax brackets for married filing jointly?
Yes. Kansas provides a separate threshold and base-tax computation for married individuals filing joint returns under the amended two-bracket structure under the current statutory structure. This calculator does not implement the married filing jointly model and estimates tax only for the non-joint (“all other individuals”) model.
What income does this Kansas tax estimate use?
This estimate uses Kansas taxable income. Kansas taxable income is a state-specific figure defined under Kansas law and Kansas Department of Revenue guidance. This calculator does not derive Kansas taxable income from federal adjusted gross income or Kansas-specific deductions and exemptions.
Which official source documents the Kansas rate change?
Kansas Department of Revenue Notice 24-08 describes changes to individual income tax and restates the amended rate structure effective under the current and ongoing statutory framework. The authority is the Kansas Department of Revenue and the controlling Kansas statute as amended.
