Anyone who was not a resident of Kansas during the tax year, but who has earned income from a source within the state is responsible for filing a Kansas income tax return. The amount of income earned in state is not relevant to determining whether or not a nonresident must file.
If Kansas state tax withholdings were completed by your employer erroneously, you’ll need to file a return in order to receive a refund. You don’t have to have income in state in order to file for a refund of taxes held, although you will have to have an authorized letter from your employer indicating the error to accompany your return.
Individuals who are in the state for less than a full year are considered part-time residents of Kansas. Part-time residents can file income tax returns as either resident or non-residents.
