Necessary FORMS For Kansas Mail in taxes

[Iammamie]

What necessary forms do you need to attach to the Kansas1040 when I send in US Mail?

[JohnW222]

According to Mailing your return on page 10 of the Instructions for Kansas 2019 Individual Income Tax,

• Enclose Schedule S if you have a modification on line 2, if you filed as a nonresident or part-year resident, or if you itemized your deductions for Kansas
• Enclose Form K-40V if you are making a tax payment
• If your K-40 is filed with a Kansas address, do not include a copy of your federal return; however, keep a copy of it in case the Kansas Department of Revenue requests it at a later date. If your K-40 shows an address other than Kansas, you must enclose a copy of your federal return (1040, applicable Schedules A-F and Schedules 1-3)

The Department of Revenue does not require that you enclose copies of W-2s or 1099s with Form K-40.

Additional requirements can be found by searching "enclose" in the pdf linked above.
