The age-26 SEP is the most predictable enrollment window in ACA. It recurs every month. A book of active clients with dependents will generate this conversation multiple times per year. Most broker workflows treat it as an exception instead of a process.
Key Takeaways
- ACA plans that cover dependents must allow children to remain on a parent's plan until age 26. Coverage typically ends on the last day of the month of the 26th birthday for employer group plans. The Marketplace follows the same rule for plans that include dependents.
- Loss of dependent coverage triggers a 60-day SEP. The window runs from the coverage end date, not the birthday. A client whose coverage ends July 31 has until September 29 to enroll on the Marketplace.
- Most clients turning 26 are in the early stages of their careers. Many qualify for APTC at lower incomes, and some qualify for Medicaid if income is below 138 percent FPL in an expansion state. Screen income before quoting plans.
- Proactive outreach before the birthday closes more enrollments than reactive outreach after coverage ends. A broker who calls 60 to 90 days before the birthday gives the client time to compare plans and enroll before the gap opens.
- A client who misses the 60-day SEP window after losing dependent coverage has no Marketplace enrollment pathway until the next OEP unless a separate qualifying event occurs.
When the coverage actually ends
The ACA requires plans that offer dependent coverage to allow children to remain on a parent's plan until age 26. The rule applies to employer group plans, individual plans, and Marketplace plans that cover dependents. Age 26 is the maximum. Carriers may extend coverage beyond that as a plan feature, but they cannot terminate it before the dependent turns 26 as long as the parent's plan is active.
The coverage end date is where brokers need to get specific. Most employer group plans end dependent coverage on the last day of the month of the 26th birthday. A client who turns 26 on March 9 typically retains coverage through March 31. Some plans end coverage on the birthday itself. A few use the plan anniversary date. The parent's plan documents or HR department can confirm. Do not assume.
For Marketplace plans, the same logic applies. If the parent has an ACA Marketplace plan that lists the dependent, the dependent's coverage ends on the applicable date under the plan terms. The new coverage the dependent needs is an individual Marketplace plan in their own name, not a continuation of the parent's plan.
The 60-day SEP window
Loss of dependent coverage is a qualifying life event. The 60-day SEP runs from the date coverage ends, not from the birthday. For a client whose coverage ends July 31, the SEP window closes September 29. For the full list of SEP triggers and their documentation requirements, read how brokers handle SEP qualifying life events.
A client who misses this window has no Marketplace enrollment pathway until the next OEP, typically November 1 through January 15, unless a separate qualifying event occurs before then. The clock starts on the coverage end date whether or not the client is aware of it.
Marketplace enrollment via this SEP can often be submitted before coverage ends, with coverage starting the first of the following month. This eliminates the gap between the parent's plan end date and the new plan start date. Timing the enrollment to land exactly at the transition requires knowing the coverage end date accurately, which is why confirming the date from the parent's plan documents is the first step, not an afterthought.
Medicaid vs Marketplace: income first
Clients turning 26 are often in the first years of a career. Incomes tend to be lower, and subsidy eligibility tends to be higher. Before pulling up plan options, run the income screen.
In Medicaid expansion states, adults with household income below 138 percent FPL are generally eligible for Medicaid. A client who is between jobs, working part-time, or in the early stages of freelance work may qualify for Medicaid rather than Marketplace coverage. The Marketplace application will evaluate Medicaid eligibility and route the client accordingly in expansion states. In non-expansion states, clients below 100 percent FPL fall into the coverage gap. For context on which states have not expanded and what options remain, read the ACA coverage gap: what brokers in non-expansion states need to know.
For clients who are self-employed or doing gig work at 26, income estimation is its own conversation. Net business income, not gross 1099 receipts, is what the Marketplace needs. For the income reporting rules that affect freelance and self-employed clients, read ACA Marketplace enrollment for self-employed and 1099 clients.
The broker process: proactive outreach beats reactive intake
A broker who calls a client 90 days before the birthday gives that client three months to understand the options, compare plans, and enroll before the gap opens. A broker who waits for the client to call is managing a 60-day deadline with a client who is already anxious and possibly uninsured.
The process is simple in concept and requires only a calendar check and a CRM tag to execute. At any point in the year, a broker who can answer "how many clients or client dependents are turning 26 in the next 90 days" has built the necessary infrastructure. Most CRM tools can surface this from a date field. The outreach from there is a phone call, not a workflow problem.
| Timing | Broker action | Notes |
|---|---|---|
| 90 days before birthday | Identify clients turning 26 in the next quarter. Begin outreach. | Pull from your CRM or client list. A book of 100 households will typically include 3 to 8 clients with dependents approaching 26 in any 12-month period. |
| 60 days before birthday | Run income screen and quote Marketplace plans or check Medicaid eligibility. | If income is below 138 percent FPL in an expansion state, direct toward Medicaid. Above that threshold, run APTC estimate and compare plans. |
| 30 days before birthday | Finalize plan selection. Submit enrollment with SEP documentation if applying pre-birthday. | Coverage can start the first of the month after enrollment. Timing the enrollment early avoids a coverage gap between parent's plan end date and new plan start. |
| Coverage end date (last day of birthday month) | Confirm enrollment is active. Verify insurance ID card was issued. | If enrollment was not completed pre-birthday, SEP clock is now running. 60 days remain from this date. |
What to cover in the first call
The initial conversation with a client turning 26 should cover four things before getting to plan options.
Confirm the coverage end date.Ask the client to check their parent's plan documents or call HR. The SEP window timing depends on this date. Getting it wrong by a week can mean missed coverage.
Establish expected income for the year. Early-career income is variable. Freelance work, multiple part-time jobs, and first full-time roles all carry different reporting implications. For self-employed clients starting out, the self-employment income deduction and SE tax adjustment both affect MAGI.
Check Medicaid eligibility. If income is under 138 percent FPL in an expansion state, the Marketplace application will likely route the client to Medicaid. Set that expectation before the application is submitted.
Discuss provider continuity.Clients turning 26 often have established pediatric or specialty providers from their parent's plan. A plan change at 26 is a network change. Confirm whether specific providers are in-network on the plans being quoted before selecting.
Enrollment platform considerations
Enrollment-integrated platforms like GetInsured AgentExpress center their workflow around the enrollment event itself: application submission, status tracking, and SEP documentation. The CRM functions are built to manage active applications, not to surface future coverage transitions. The proactive identification of clients turning 26 still requires a separate process, whether that is a calendar reminder, a spreadsheet, or a CRM field query.
The enrollment step, once the client is in the 60-day window, is straightforward. The work that prevents the 60-day scramble is the tracking that happens months before.

FAQ
Questions brokers and clients ask about the age-26 dependent coverage transition and Marketplace enrollment.
When exactly does coverage end on a parent's employer plan?
For most employer group plans, dependent coverage ends on the last day of the month of the dependent's 26th birthday. If a client turns 26 on July 15, coverage typically ends July 31. Some plans end coverage on the birthday itself, and some use the end of the plan year. The parent's HR department or plan documents are the authoritative source. Do not assume the date without checking.
Does the 60-day SEP run from the birthday or the coverage end date?
The SEP runs from the coverage end date, not the birthday. If the parent's plan ends coverage on the last day of the birthday month, the 60-day window starts the following day. A client turning 26 in July with coverage ending July 31 has until September 29 to enroll on the Marketplace via SEP.
Can a client enroll on the Marketplace before coverage ends?
Yes. Marketplace enrollment for a loss-of-coverage SEP can often be submitted in advance, with coverage starting the first of the month after the existing coverage ends. This prevents a gap. Check current CMS guidance on pre-SEP enrollment timing, as the rules around advance enrollment have varied across plan years.
What if the client has low income and might qualify for Medicaid?
Screen income first. In Medicaid expansion states, adults with income below 138 percent FPL are generally eligible for Medicaid. A client turning 26 who is between jobs or early in their career may qualify. Submitting a Marketplace application in expansion states will route Medicaid-eligible applicants to Medicaid automatically. In non-expansion states, clients below 100 percent FPL may fall into the coverage gap with no Marketplace option.
What documentation does the Marketplace require for this SEP?
CMS may request documentation confirming the loss of employer-sponsored dependent coverage. Acceptable documentation typically includes a letter from the employer or plan administrator confirming coverage end date, or a notice from the insurance carrier. Requirements can vary. Check current CMS SEP documentation guidance or Healthcare.gov for the most recent verification standards.
