I am trying to file my 17 year old sons taxes for him. I have already done mine and just need to do his. How do I do that?

If you are using TurboTax online, you will need to create a new account to file his return.  The online account can only be used to file one return.   When you start his return and in the beginning sections under personal info, be sure that you check the box that says someone else can claim me as a dependent, assuming he was claimed as a dependent.

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.
