My daughter, 18 month old and her boyfriend lived with me. Can I claim my daughter and her boyfriend even though she is filing and claiming her own child and how would I?

[fanfare · Accepted solution]

Yes if they  did not provide more than half of their own support for the year

BUT If she can be claimed as a dependent by another person (you), she can't claim anyone else as a dependent. Even if she has a qualifying child or qualifying relative, she can't claim that person as a dependent.

This is called the Dependent Taxpayer Test

How old are they?
Has Boyfriend lived there all year?

21

Has Boyfriend lived there all year?

I think @fanfare misread your Q and thinks Daughter is age 18. Since she and BF are 21, the rules are different, unless they are full time college students. You must have provided more than 50% of their support for the entire year, and each cannot each have more than $4050 of 2017 income.

and BF must have lived there all year, since he is not related to you.

See IRS Pub 501 Table 5 for who can be a dependent on your tax return.

If she qualifies to be your dependent she will have to check the box on her own return that says Someone else can claim her.  If she is your dependent and files her own return she can not claim any dependents on her return. Then you could probably claim the baby and maybe even the boyfriend if he lived with you the whole year.
