General Tax Return Information
Due Date - Individual Returns - April 15, or same as IRS
Extensions - If Form 4868 is filed with the Internal Revenue Service requesting an automatic extension of time to file federal tax return, an extension of time to file for the Kansas return will automatically be received. A copy of form 4868 must be enclosed with the Kansas income tax return when filed. Kansas does not have a separate extension form, if entitled to a refund, an extension is not required. This is not an extension of time to pay.
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 taxpayer does not pay the tax due (may be estimated) by the original due date, they will owe interest and penalty on any balance due.
Driver’s License/Government Issued Photo Identification: This information is not required to file, however, the state of Kansas is requesting additional information in an effort to combat stolen-identity tax fraud.
Filing Status Information
The Kansas filing status must be the same as the Federal filing status.
Residency Status Information for Kansas Returns
Residents: A Kansas resident for income tax purposes is anyone who lives in Kansas, regardless of where they are employed. An individual who is away from Kansas for a period of time and has intentions of returning to Kansas is a resident.
Part-year resident: A taxpayer considered a part-year resident of Kansas if they were a Kansas resident for less than 12 months during the tax year
Nonresidents: If the taxpayer is not a resident of Kansas but received income from Kansas sources, they must file a Kansas return regardless of the amount of income received from Kansas sources. If the employer withheld Kansas taxes from their wages in error, they must also file a Kansas return in order to receive a refund, even though they had no income from Kansas sources. A letter from the employer on company letterhead and signed by an authorized company official explaining the error must accompany their return. The letter must state the amount of wages and withholding applicable to Kansas.
Military Personnel/Military Spouses
Residents: If personnel's home of record on their military records is Kansas, and they have not established residency in another state, they are still a Kansas resident and all of their income, including military compensation, is subject to Kansas income tax.
Nonresidents: If the personnel are a nonresident of Kansas but are stationed in Kansas due to military orders, they must file a Kansas return if they received income from Kansas sources. Only income from Kansas sources is used to determine the Kansas income tax due for nonresident military service members.
Military spouses: Under the Military Spouses Residency Relief Act, a military spouse’s state of residence does not change when moving to a new state to be with a service member stationed there if the residence or domicile is the same for the service member and spouse.
