If your son has a W-2 for
his job you do not include
the information on your own return. You can still claim your child as a
dependent on your own return. He 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 you MUST indicate on his return 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 then he must file a return and
pay self-employment tax for Social Security and Medicare. You may want to
use this version of TT for that:
