What are Kansas income tax brackets for 2024?

Kansas has three graduated brackets. For single filers it is 3.1% on the first $15,000 of taxable income, 5.25% from $15,000 to $30,000, and 5.7% above $30,000. Married-filing-jointly thresholds are doubled: 3.1% to $30,000, 5.25% to $60,000, and 5.7% above that.

What is the Kansas standard deduction?

For 2024 the Kansas standard deduction is $3,500 for single filers, $8,000 for married filing jointly, $6,000 for head of household, and $4,000 for married filing separately. You may itemize instead if your itemized deductions exceed these amounts.

Does this calculator include federal income tax?

No. It computes only the Kansas state income tax. Federal income tax, FICA, and any local taxes are separate. Use it to estimate the state-level line of your overall tax picture, then add federal separately.

Is Kansas income tax a flat rate?

No. Kansas uses a three-bracket graduated structure topping out at 5.7%. Lower-income filers pay a 3.1% marginal rate, while higher earners reach the 5.7% top rate on income above the upper threshold.

Kansas levies a graduated state income tax with three brackets that top out at 5.7 percent. This calculator applies the official 2024 thresholds for your filing status, subtracts your standard or itemized deduction and your personal exemptions, and shows the tax due along with your effective and marginal rates.

How it works

Kansas taxes income in three slices. For a single filer the first 15,000 dollars of taxable income is taxed at 3.1 percent, income from 15,000 to 30,000 dollars at 5.25 percent, and everything above 30,000 dollars at 5.7 percent. Married couples filing jointly use doubled thresholds: 3.1 percent to 30,000 dollars, 5.25 percent to 60,000 dollars, and 5.7 percent above that.

Taxable income is computed as:

taxable = AGI − deduction − (exemptions × $2,250)

The standard deduction is 3,500 dollars (single), 8,000 dollars (joint), 6,000 dollars (head of household), or 4,000 dollars (married filing separately). Each exemption you claim — yourself, your spouse on a joint return, and each dependent — is worth 2,250 dollars.

Example

A single filer with 50,000 dollars of Kansas AGI claiming one exemption subtracts the 3,500 standard deduction and 2,250 exemption, leaving 44,250 dollars taxable. The tax is 3.1% of 15,000 (465 dollars) + 5.25% of 15,000 (787.50 dollars) + 5.7% of the remaining 14,250 (812.25 dollars), about 2,064.75 dollars, an effective rate near 4.1 percent.

Notes

This simplified tool models the headline 2024 brackets, standard deduction, and 2,250-dollar exemptions. It does not model Kansas tax credits (food sales tax credit, child and dependent care credit, earned income credit) that may further reduce your tax.
