I didnt include my son's W-2 in my taxes...

[ppayne15]

He made 4.5K last summer...what do I do?

[CatinaT1]

You do not include them in your taxes. He needs to file his own return. Does he have federal or state withholdings?

He might not have a filing requirement but want to file to get a refund of his withholdings. Tax Filing Requirements for Children - TurboTax - Intuit

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 from boxes 2 or 17 (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.
