Kansas
State Business Income Tax Extension

What Form does the state of Kansas require to apply for
an extension?

There is no state-specific form to request an extension, as the state of Kansas automatically provides the extension for up to 6 months for businesses to file an income tax return with the state. If you filed federal Form 7004 with the IRS for an extension, enclose a copy of that form with your completed K-120 to automatically receive a six-month extension to file your Kansas return
