Extension Form Kansas Extension Instructions How to File

No Form

Kansas does not have a separate extension form. If you file Form 4868 requesting an automatic six-month extension of time to file your federal tax return, you will automatically receive a six-month extension of time to file your Kansas state return (not to pay KS taxes owed). A copy of form 4868 must be enclosed with your Kansas return.

To make an extension payment on your Kansas income tax, use the Kansas Payment Voucher (K-40V). Check the box on the voucher for extension payment. The extension payment must be postmarked on or before April 18, 2017. Any balance due remaining after April 18, 2017 will include interest. To avoid a separate penalty charge, you must have 90% of your tax be paid by April 18, 2017. In addition, any remaining balance due must be paid within the extended due date.

Include copy of federal Form 4868 with Kansas return

Important Reminder! If you are efiling a Kansas tax extension, you may need to efile a federal tax extension as well.

Kansas state amended tax returns can only be filed by mailed; they cannot be efiled. Learn how to prepare and file a Kansas state tax amendment.

KS Personal Property Tax:

The state's personal property tax values vary based on county.

Homes, commercial real property, and certain other property types are appraised at "market value" as of the first day of January each year. Agricultural land, certain motor vehicles, and commercial and industrial machinery/equipment are appraised using a value-assessed method.

A rebate on a portion of property taxes paid on a Kansas resident's main personal property is available through the homestead refund. Qualified residents can claim the refund by filing Form K-40H.

Odd Tax Fact:

Kansas requires drug dealers possessing marijuana and/or other controlled substances to pay the state's drug tax. The state defines a drug dealer as

  • Anyone who produces, transports, manufactures, imports, or ships illegal substances into the state OR
  • Anyone who possesses more than 28 grams of marijuana (processed or marijuana plants), one gram of a controlled substance, or 10 or more dosage units of a controlled substance.

In exchange for the tax payment, drug dealers receive drug tax stamps, which must be attached to the substances and are valid for three months. Though the stamps do not make the possession of these drugs legal, having drugs without stamps or expired stamps may result in civil or criminal penalties. These penalties may include seizure of property or fines.
