  • Extension Mailing Address:
    If you are unable to complete your Kansas return by the filing deadline, you may request an extension of time to file. If you filed federal Form 4868 with the IRS for an automatic extension to file, enclose a copy of this form with your completed Form K-40 to automatically receive an extension to file your Kansas return. Kansas does not have a separate extension request form. If you are entitled to a refund, an extension is not required. To pay the tax balance due for an extension, use the Kansas Payment Voucher (K-40V) and mark the box indicating an extension payment. If you do not pay the tax due (may be estimated) by the original due date, you will owe interest and penalty on any balance due.





  • Electronic Filing:
    Kansas accepts Resident, Nonresident, and Part-year returns electronically. They can be transmitted with the Federal return or transmitted as a State only return.
