My daughter is 18 year old full time student and made $9,000. Does she file on her own? Can I still claim her? Do I add her income to Our return?

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.

You do not report your daughter's income on your return.

You can claim her as a dependent as she is under 24 and a full-time student.

If her income is wages reported on form W-2, she is not required to file a tax return if she earned less than $12,950. However, if she had taxes withheld, she can file a tax return to claim a refund.

If her income is self-employed income reported on form 1099-NEC, she is required to file a tax return if she earned more than $400.

If she files a tax return, she has to indicate in TurboTax that she can be claimed as a dependent by someone else.
