Illinois Taxes for F-1 Students: When Schedule NR Applies
Illinois student residency and source-income rules, including Form IL-1040 and Schedule NR for some nonresidents.
Illinois explicitly says students are not exempt from its income tax just because they attend school. Its residency rules are separate from the federal F-1 substantial presence rules. A nonresident student with enough Illinois-source income can need Form IL-1040 plus Schedule NR.
Determine state residency
Illinois’s student guidance describes full-year resident, part-year resident, and nonresident situations. It gives an example of a student attending school in Illinois while remaining a resident of another state. Your actual legal residence, move history, and income source matter.
Do not transfer the federal Form 1040-NR label directly to Illinois. A person can be a federal tax nonresident and still face different state classification.
Check the filing threshold and withholding
The Illinois Department of Revenue says a nonresident generally files IL-1040 with Schedule NR when Illinois-source base income exceeds the exemption allowance or when seeking a refund of Illinois tax withheld in error. A part-year resident has its own conditions. Review the current year’s instructions and W-2 state wage boxes.
Schedule NR allocates income to Illinois. Keep pay statements and work-location records, especially when a job spans Illinois and another state.
Choose a supported filing route
A federal Form 1040-NR package does not automatically prepare IL-1040 and Schedule NR. Verify current software coverage for both forms and any state-specific schedules before paying. If an Illinois form is not generated for your circumstances, use Illinois’s instructions or a qualified alternative.
What to do next
Use Illinois’s student guidance and Schedule NR instructions to determine whether a separate state return is due.
