If your daughter will be under age 19 by the end of the year, you probably can claim a dependency exemption for her, even though she is on active duty and has gross income over the exemption amount ($4,050 in 2016). She merely has to have lived with you for more than half the year, but military service is treated as a temporary absence. However, if she’s at least 19 years old by the end of the year, you’re out of luck. At this age, she’s no longer a qualifying child and can’t be claimed as a dependent if her gross income exceeds the exemption amount, which you say it will.
Gifts in excess of an $12,000-per-donee annual exclusion are subject to gift tax, but the tax may be offset by a gift tax credit.
