Kansas Filing Due Date: Individual income tax returns are due by April 15, in most years — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with Kansas Tax Extension: Kansas offers a 6-month extension to taxpayers who have a valid Federal tax extension (IRS Form 4868), which moves the filing deadline from April 15 to October 15 (for calendar year filers).
Kansas Tax Extension Form: Kansas tax extensions are automatic, so there’s no application form or written request to submit. In order to automatically receive a Kansas extension, you must first obtain a Federal extension (IRS Form 4868). Remember to include a copy of your approved Federal extension with your Kansas tax return when you file.
Kansas Extension Payment Requirement: An extension of time to file is not an extension of time to pay your Kansas income tax. All state tax payments are due by the original deadline of the return. Any Kansas tax that isn’t paid by the proper due date will be subject to interest. Furthermore, to avoid a separate penalty charge, you must pay at least 90% of your Kansas tax due by the original deadline. You can use Form K-40V to make a tax payment for your Kansas extension.
Kansas Tax Extension Tip: Do not file Form K-40V if you owe zero Kansas income tax or you expect a Kansas tax refund. In those cases, an extension is not required.
