Can I claim my son for the first 3 months of the year before he joined the military

[KiaraE · Accepted solution]

No, in order to claim a dependent they must meet the following requirements:

• The child can be your son, daughter, stepchild, eligible foster child, brother, sister, half brother, half sister, stepbrother, stepsister, adopted child or an offspring of any of them.
• Your child must be under age 19 or, if a full-time student, under age 24. There is no age limit if your child is permanently and totally disabled.
•  Your child must live with you for more than half the year, but several exceptions apply.
• Your child may have a job, but that job cannot provide more than half of her support.
• This requirement commonly applies to children of divorced parents. Here you must use the “tie breaker rules,” which are found in IRS Publication 501. These rules establish income, parentage and residency requirements for claiming a child.
