The child must be: (a) under age 19 at the end of the year and younger than you (or your spouse, if filing jointly), (b) under age 24 at the end of the year, a full- time student, and younger than you (or your spouse, if filing jointly), or (c) any age if permanently and totally disabled.
In the interim, CAMFT recommends members to follow the law prior to the changes which defines an elder as 65 years or older and a dependent adult as a person who is between 18-64.
But did you know you can claim adult dependents as well? In general, an adult that you can claim as a dependent on your tax return is either a full-time student under the age of 24, a person who is permanently and totally disabled, or a parent that you support and/or care for.
Employers in California with insured and self-funded health plans are required to maintain dependent coverage up until age 26. If group health plans provide coverage past age 26, they are required to extend coverage to qualifying students who would otherwise lose coverage due to a medically necessary leave of absence.
Tax Dependents Children must be under 26 to be eligible for dependent coverage. Children must be under 19 (or 24 if a full-time student) to be claimed as Qualifying Child. No age limit on being claimed as a Qualifying Relative.
