ACA dependent coverage age 26

What the age 26 rule says

The ACA dependent coverage rule allows a young adult to stay on a parent's health plan until age 26. The rule applies to most job-based plans and individual market plans that offer dependent coverage.

The young adult does not need to live with the parent, be a student, or be claimed as a tax dependent. Those old rules generally do not apply under the ACA.

The coverage generally ends on the young adult's 26th birthday. The exact end date can depend on the plan's rules and the birthday. The plan should explain the last covered day.

The rule does not require every plan to offer dependent coverage. It requires plans that offer dependent coverage to make it available to adult children until 26. A plan that does not offer dependent coverage at all is a different situation.

Who can stay on the plan

A young adult can generally stay on a parent's plan until 26, even if the young adult is married, in school, or working. The rule is designed to make coverage less dependent on those factors.

A young adult who is offered coverage through a job can generally stay on the parent's plan. The offer of other coverage does not automatically end the option. The young adult can compare the two plans and choose.

A young adult who is married can stay on the parent's plan. The spouse cannot be added as a dependent under the age 26 rule. The spouse may need separate coverage.

A young adult who is not a tax dependent can still stay on the plan in most cases. The tax treatment of the coverage can differ, but the eligibility rule is separate.

Marriage, school, and work

Marriage does not end the age 26 option. The young adult can remain on the parent's plan, but the spouse is not covered. The plan may ask for a marriage certificate for its records.

School status does not matter. A young adult who is not a full-time student can stay on the plan. A young adult who takes a break from school can also stay.

Work status does not automatically end the option. A young adult who has a job and is eligible for the employer's plan can usually stay on the parent's plan until 26. The young adult should compare the costs and the networks.

A young adult who joins the military may have other coverage options. The plan rules and the military coverage rules should be checked. The age 26 rule does not override the military rules.

Employer plans and grandfathered plans

Most employer plans must offer dependent coverage until 26. A grandfathered plan may have some differences, but the age 26 rule generally applies. The plan documents should explain the coverage.

A self-insured employer plan may have its own administration. The rule still generally applies, but the plan's documents are the source for the details.

A small employer plan may not offer dependent coverage at all. If it does, the age 26 rule generally applies to the dependent coverage it offers. The human resources office can explain.

A plan may require the young adult to be enrolled during the employer's open enrollment or a special enrollment period. A birthday or a loss of other coverage can create a window.

Costs and taxes

A parent may be able to keep the young adult on the plan at a higher premium. The plan may charge more for dependent coverage. The parent should compare the cost with the young adult's other options.

The tax treatment of the coverage depends on the plan and the young adult's status. Employer-provided coverage for an adult child under 26 is generally excluded from the parent's income, but the rules can be complex. A tax preparer can explain the specific situation.

A young adult who is not a tax dependent may still be covered, but the parent should check the tax documents. The plan may report the coverage on a form. The parent should keep the records.

A young adult who has access to a subsidized marketplace plan may compare the cost. The parent's plan may be cheaper, or the marketplace plan may offer a better network. The comparison should include the premium, the deductible, and the doctors.

State rules and turning 26

Some states require plans to cover adult children beyond age 26. The state rules can vary, and they may apply to certain plans. A person should check the state insurance department or the plan documents.

When the young adult turns 26, the coverage generally ends. The young adult may have a special enrollment period for marketplace coverage. The loss of dependent coverage can qualify.

The young adult should apply before the coverage ends if possible. The marketplace can explain the window and the documents. A gap in coverage can be costly.

A young adult who has an employer plan may be able to enroll when the dependent coverage ends. The employer's rules and the plan's enrollment window matter.

Worked example

Suppose a young adult is 24 and covered on a parent's employer plan. The young adult gets married. The young adult can generally stay on the parent's plan until 26. The spouse is not covered by the parent's plan.

A second young adult is 25 and works a full-time job with an employer plan. The young adult compares the employer plan with the parent's plan. The young adult can generally stay on the parent's plan, but the cost and network may differ.

A third young adult turns 26 in June. The parent's plan ends the coverage on the birthday. The young adult applies for marketplace coverage during the special enrollment period and chooses a plan.

A fourth young adult lives in a state that extends dependent coverage beyond 26. The state rule may allow more time, but the plan documents and the state insurance department are the source.

A parent should review the plan's dependent rules before the birthday, because the end date and the notice requirements can vary. The young adult should also compare the cost of the parent's plan with an employer plan or a marketplace plan before the change. Planning ahead avoids a gap.

Three honest caveats

1. The age 26 rule generally applies to plans that offer dependent coverage. A plan without dependent coverage is different.
2. The young adult's spouse is not covered by the parent's plan under the age 26 rule.
3. State rules can extend coverage beyond 26. Check the plan and the state insurance department.
