Stimulus question

That is how it should work.    You can claim your 18 year old as a qualifying child dependent.   If your child has any income the child can file his own return but must say he can be claimed as someone else's dependent.

You can claim a child, relative, friend, fiance (etc.) as a dependent on your 2019 taxes as long as they meet the following requirements:

•They are a U.S. citizen, resident alien, national, or a Canadian or   Mexican resident.

•They are not filing a joint return with their spouse.

• No age limit for permanently and totally disabled children

  •      They live with you for more than half the year (exceptions apply).

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them.

Thank you. But because she does not need to file because her income was under the limit, it is better for me to claim her?
