For both Wisconsin and Illinois, you can choose to file different filing status for federal and state. However, because Wisconsin is Community property, you must factor this when deciding which return to file.
If you file a joint federal return and one spouse is a full-year Illinois resident while the other is a part-year resident or a nonresident (e.g., military personnel), you may choose to file “married filing separately.” Do not recompute any items on your federal return. Instead, you must divide each item of income and deduction shown on your joint federal return between your separate Illinois returns following the Allocation Worksheet in the Form IL-1040 Instructions.
