Do I file my taxes separately from my 17 year old daughter or do we file jointly

[Bsch4477]

Report her income on her own return if she has a filing requirement or is filing to get her tax withheld. Be on her return that you check the box saying that someone can claim her.

And if you are using the "Online" software....you must use a separate account for her.  Do Not use your own "Online" account.

If you use the Desktop/Download software, you can create separate tax returns for multiple family members on it with one software package....as long as you only use a computer(s) you actually own.

"Joint" returns are filed by legally married couples--not by a parent and child.

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.
