Can I claim my domestic partner as a dependent if she made no income during 2016?

She was a full time masters student and we have a child together.

Yes, you can claim her as a dependent if she passes all of the following tests:

1.  The person can't be your qualifying child or the qualifying child of any other taxpayer. 
2. The person must live with you all year as a member of your household (and your relationship must not violate local law). 
3. The person's gross income for the year must be less than $4,050. 
4. You must provide more than half of the person's total support for the year.
5. The person is a U.S. citizen, U.S. resident alien, U.S. national.
6. The person is not a married person who files a joint return unless that joint return is filed only to claim a refund of withheld income tax or estimated tax paid.

If you have a child, you can claim that child as your dependent and file as Head of Household if you paid more than half of the cost of keeping up a hom.
