Turning 26 and losing a parent's health plan in Utah

Hannah Pierce turns 26 on Sunday, June 14, 2026. She is a marketing coordinator at a small agency in Sugar House, in Salt Lake City, where she writes client newsletters and plans their social media posts. The agency has 9 employees and doesn’t offer health insurance.

She has been on her father’s health plan through his job for as long as she can remember. In April, he forwarded her a notice from the plan. Her coverage as his dependent would end on the last day of the month she turns 26: Tuesday, June 30.

Does turning 26 and losing a parent’s plan let you buy a marketplace plan outside open enrollment? Yes. Losing a parent’s plan counts as a loss of coverage. The Special Enrollment Period opens 60 days before the coverage ends and closes 60 days after. A plan picked before the old coverage ends starts the first of the month after.

Hannah and her family are fictional; the rules come from HealthCare.gov and CMS, and the income figures from the IRS and HHS.

Aging off a parent’s plan, in brief

Utah uses HealthCare.gov, so these are its rules:

• What counts. Aging off a parent’s plan at 26 is a loss of coverage, one of the qualifying life events that open a Special Enrollment Period.
• The window. HealthCare.gov says the window starts 60 days before the coverage is lost and ends 60 days after.
• The end date. When a parent’s plan ends a 26-year-old’s coverage depends on the plan. If the parent’s plan is a marketplace plan, the child can stay on it until December 31.
• When the new plan starts. Picked on or before the last day of the old coverage: the first of the month after that coverage ends. Picked after: the first of the month after picking.
• Proof. The marketplace may ask for documents proving the loss. After picking a plan, there are 30 days to send them.

Hannah’s story

The notice

Hannah read the notice twice on her lunch break, at her desk a block off Highland Drive. Her first thought was that she would be uninsured on July 1 and stay that way until open enrollment. She had a checkup she’d been putting off, and a running habit that had already cost her a sprained ankle.

The worry lasted about an evening. The next morning her father called the HR office at his job, which confirmed the June 30 date by email. That night Hannah read the HealthCare.gov pages on losing coverage and found that aging off a parent’s plan opens its own window. She didn’t have to wait for open enrollment.

When the clock started

Her window opened 60 days before June 30, at the start of May, and would close 60 days after it, near the end of August.

The window was long, but the start date of her new plan depended on when she picked it. Any plan she picked on or before June 30 would start July 1, the first of the month after her father’s plan ended. If she waited until July or August, the new plan would start the first of the month after she picked it, and she would be uninsured in between.

She put a reminder on her calendar for the first week of June. That gave her time to work out her income and think through her choices, without leaving it to the last day.

Estimating her income

The premium tax credit is based on household income for the whole calendar year. Hannah is single, with no children and nobody else on her tax return, so her household is 1 person.

Her salary is $31,000 a year, and she has no other income. Her estimate for 2026 was $31,000.

She checked that number against 3 lines for a household of 1:

• 138% of the poverty guideline, about $21,597. Utah adults below it qualify for Medicaid on income alone, so the application would have checked her for Medicaid instead.
• 200%, $31,300. Between 150% and 200%, a Silver plan comes with cost-sharing reductions at the 87% level.
• 400%, $62,600. Above it, there is no premium tax credit in 2026.

At $31,000, she was above the Medicaid line, well under 400%, and $300 under the 200% line.

Her agency offers no health coverage, so there was no job-based plan to weigh against the credit.

Weighing her options

COBRA. If her father’s plan offered her COBRA, she would weigh it too. COBRA itself comes with no premium tax credit. Being offered COBRA wouldn’t stop her from turning it down and getting the credit on a marketplace plan, if she qualified.

A Bronze or Gold marketplace plan. The premium tax credit can be used on any metal level. Since January 1, 2026, Bronze plans count as HSA-eligible high-deductible plans, which matters to some people. But cost-sharing reductions come only with a Silver plan.

A Silver marketplace plan. A standard Silver plan has a 70% actuarial value. At Hannah’s income, a Silver plan comes with cost-sharing reductions that raise it to 87%. Higher actuarial value means the plan pays a bigger share of covered costs, through lower deductibles and copays.

Hannah expected to use her plan: the checkup, and another visit if the ankle acted up again. The 87% level comes only with Silver, so she chose Silver.

Picking a plan

On Wednesday, June 3, after work, Hannah filled in the application on HealthCare.gov. She reported the loss of coverage with its date, June 30, a household of 1 and income of $31,000. The application found her eligible for the premium tax credit, and for cost-sharing reductions with a Silver plan.

She compared the Silver plans on the list, checked which ones had a primary care clinic near her apartment in their network, and picked one. Because she picked it before June 30, it would start on Wednesday, July 1. No gap.

She chose to have her credit paid in advance each month, based on her $31,000 estimate. That’s why the estimate matters, and why she’ll report any change to it.

The paperwork

The marketplace may ask for documents proving a loss of coverage, and there are 30 days after picking a plan to send them. Hannah saved the plan’s notice and the HR email with the June 30 date in a folder on her laptop, ready to send if asked.

She also wrote down another rule. Enrollees must report changes in income, household members, address and citizenship or immigration status within 30 days.

The first months

Her father’s plan covered her through June 30, and her Silver plan started on July 1. In August she finally booked the checkup she had been putting off, at an in-network clinic a few blocks from her apartment. The ankle held up.

In October she checked her pay stubs against her $31,000 estimate. Her pay hadn’t changed, so there was nothing to report.

The numbers

Household: 1 person.

Poverty guideline used for 2026 coverage, 1 person: $15,650.

Estimated 2026 income: $31,000.

Step 1. Income as a share of the guideline: $31,000 divided by $15,650 is about 1.98, or about 198%.

Step 2. The applicable percentage. For 2026 it rises on a sliding scale from 4.19% at 150% to 6.60% at 200%. At about 198%, near the top of that band, it is about 6.51%.

Step 3. The expected contribution for the year: $31,000 times 6.51% is about $2,018.

Step 4. By the month: $2,018 divided by 12 is about $168.

Hannah is expected to pay about $168 a month toward the benchmark plan, the second-lowest-cost Silver plan where she lives. The premium tax credit covers the rest of the benchmark’s premium, whatever that premium is. If she picks a plan that costs more than the benchmark, she pays the difference on top of that $168. If she picks one that costs less, she pays less.

Step 5. Cost-sharing reductions. At about 198%, over 150% and not over 200%, her Silver plan has an 87% actuarial value instead of the standard 70%. Cost-sharing reductions don’t come with Bronze or Gold plans.

The limits. The credit is for household income from 100% to 400% of the poverty guideline ($62,600 for 1 person in 2026), on a plan bought through the marketplace, for someone not eligible for Medicaid, CHIP or affordable job-based coverage. Cost-sharing reductions are 94% from 100% to 150%, 87% over 150% to 200%, 73% over 200% to 250%, and none above 250%.

What could have gone wrong

Waiting past June 30. Her window ran 60 days past the end of her father’s plan. But a plan picked in July or August would have started the first of the month after she picked it, leaving at least a month uninsured. Once the window closed, she would have needed another qualifying life event or open enrollment.

Assuming the end date. The plan sets it. Hannah’s ended on the last day of her birthday month because that’s what her father’s plan said. If her parents’ plan had been a marketplace plan, she could have stayed on it until December 31.

A small raise. The 200% line for 1 person is $31,300, and Hannah is $300 under it. Suppose her agency had given her a raise that brought her 2026 income to $31,700 instead.

• $31,700 divided by $15,650 is about 2.03, or about 203%.
• Her cost-sharing reductions drop from the 87% level to 73%.
• Her applicable percentage moves into the 200% to 250% band, which starts at 6.60%, and her expected contribution rises to about $177 a month.

She would report the raise within 30 days. If her income came in higher than her estimate without an update, she would repay the extra advance credit at tax time. There is no repayment cap for tax years after 2025. If her income came in lower than her estimate, she may get more back.

Coverage offered at work. If her agency later offered health coverage that is affordable and meets minimum value, she couldn’t get the credit. In 2026, job-based coverage is affordable if the employee’s share for self-only coverage is no more than 9.96% of household income. She would report the offer.

Dropping coverage on purpose. Dropping coverage voluntarily doesn’t open a window. If she had taken COBRA and later stopped paying for it on her own, that wouldn’t qualify either.

A lower income. Under 138% of the poverty guideline, about $21,597 for 1 person, Hannah would have been checked for Medicaid instead. That wasn’t her case. Medicaid applications are open any time of year.

Questions to work through

When does your parent’s plan end your coverage? It depends on the plan. Read the notice, or ask the plan or the HR office for the date in writing. If it’s a marketplace plan, you can stay on it until December 31.

Have you counted back 60 days? Your window opens 60 days before that date. Pick a plan on or before the last day of your old coverage, and the new one starts the first of the next month.

What will your income be for 2026 as a whole? The credit is based on the calendar year, including wages you’ve already earned. Divide your estimate by the poverty guideline for your household size.

Are you close to a line? For 1 person, 138% is about $21,597, 200% is $31,300 and 400% is $62,600. A raise or a side job near one of those lines can change your cost-sharing reductions or your credit. Report the change within 30 days.

Were you offered COBRA? COBRA itself comes with no premium tax credit. Being offered it doesn’t keep you from turning it down and getting the credit on a marketplace plan, if you qualify.

Does your job offer coverage? If it’s affordable and meets minimum value, you can’t get the credit. A licensed broker can check this with you.

The short version

Hannah aged off her father’s plan on June 30, 2026. Losing it opened a Special Enrollment Period from 60 days before that date to 60 days after. She picked a Silver plan on HealthCare.gov on June 3, so it started July 1 with no gap. At $31,000, about 198% of the poverty guideline, her expected contribution toward the benchmark plan is about $2,018 a year, or about $168 a month, and her Silver plan comes with cost-sharing reductions at the 87% level. A raise past $31,300 would lower that level to 73% and raise her expected contribution, so she reports any change within 30 days.
