Minor filing question is there a minimum on federal wages and Illinois state to file for both?

MY DEPENDENT HAD A JOB

If your dependent has a W-2 for his after-school job, summer job, etc. you do not include the information on your own return. You can still claim your child as a dependent on your own return.  He/she can file his own return for a refund of some of his withheld wages (he won’t get back anything for Social Security or Medicare), but MUST indicate on it that he can be claimed as a dependent on someone else’s return.  (Supervise this closely or prepare it for him!)

If your dependent’s earnings were over $400 and were reported on a 1099Misc or 1099NEC then he must file a return and pay self-employment tax for Social Security and Medicare.

There is a minimum amount of income under which you are not required to file a federal or Illinois income tax return. For the federal return, you should use this tool provided by the IRS to determine if you need to file, as the minimum income may be only one factor that you need to consider:  Do I need to file a tax return

For 2023, if you are filing single as a non-dependent, you must file a return if your income is over $2,425.
