Kansas State Income Tax Overview

The Kansas Department of Revenue oversees state income tax for individuals who live in or earn income from a source based in Kansas.  Individuals who meet the minimum filing requirements must file a state income tax return with Kansas, which is a separate income tax return from that filed for federal income tax purposes with the Internal Revenue Service (IRS).

Non-Residents

If you did not live in Kansas for any part of the tax year but you received income from a source based in Kansas, you must file a Kansas state income tax return regardless of the amount of income you received from sources based in Kansas.

In addition, if you had tax withheld from your Kansas wages, you must file a Kansas state income tax return to receive a refund of those tax withholdings.

What tax rate does the Kansas Department of Revenue use for calculating state income tax?

Kansas uses a marginal tax rate that increases with additional income earned.  The tax rates are assessed per the following table:

What is the tax rate used by Arkansas for state income tax?

Arkansas applies a marginal tax rate as shown in the table below:

Taxable Income Tax Rate
Up to $15,000 3.5%
$15,000 to $30,000 6.25%
$30,000 and over 6.45%

What number of exemptions can I claim on my Kansas state income tax?

The number of exemptions for state income tax is the same as what you can claim on your federal income tax return, except in the case of those who file Head of Household or Qualifying Widow(er) who receive one additional exemption above that allowed for federal income tax purposes.

What is the filing date for my Kansas state income tax?

The normal filing date is April 15, or if April 15 falls on a holiday or weekend, the first non-holiday business day after April 15.

You can obtain an extension by filing federal Form 4868 with the IRS for your federal income tax, which also grants you an extension for your Kansas state income tax return.  The extension does not grant additional time to pay any tax liability due.  Therefore, an estimate of any tax payment must still be made on April 15.

If you do not pay at least 90% of your tax liability by April 15, you will be charged a penalty on your state income tax.  In addition, you will be charged interest on any unpaid tax balance due.
