Yes, as long as she meets the following rules:
A qualifying child meets all six of the following conditions:
Relationship:?The person is your child, foster child, adopted child, brother, sister, stepbrother, stepsister or a descendent of one of these (for example, grandchild, niece or nephew).
Residence:?The person lives in your home for more than half the year. If he or she is temporarily absent, that still counts as time living in your home. A temporary absence could be time spent at college or boarding school, or time away for medical care, military service or juvenile detention.
Age:?The person is age 18 or under at the end of 2015, or a full-time student age 23 or under. If the person is disabled, there is no age limit.
Support:?The person doesn’t provide more than half of his or her own support.
Nationality:?The person is a U.S. citizen, U.S. resident alien, U.S. national, or a resident of Canada or Mexico. An adopted child?who doesn’t meet this requirement but lives with you for the entire year can be your dependent, as long as you’re a U.S. citizen.
Marital status:?Generally, a married dependent can’t file a joint tax return with a spouse. The only exception is when the married dependent files a joint return only to get a refund of taxes paid (no tax credits are received) and, if separate returns are filed, neither the dependent nor spouse would have a tax liability.
