He’ll Retire From His Corporate Job at 62 With a 401(k). His Wife Will Be 59. Who Will Cover Her Health Insurance for the Next Six Years?

A corporate employee who retires at 62 with a 401(k) and a 59-year-old spouse has two coverage gaps to fill. A three-year bridge runs him to Medicare at 65, while she needs coverage for six years. The first choice comes quickly. Under federal law, the COBRA election period has to last at least 60 days, and it cannot close before 60 days have passed after the later of two dates: when his employer coverage ends or when the election notice arrives.
The example that follows uses a married couple filing jointly with a company pension and a 401(k) he will draw on before claiming Social Security. Each option below depends on household income, because the marketplace premium tax credit is built on that number.
Four Coverage Paths Carry Four Different Credit Rules
| Option for her | How long it lasts | Premium tax credit effect |
|---|---|---|
| His employer’s COBRA | 18 months after a termination of employment | Credit is unavailable in the months she is enrolled |
| ACA marketplace plan | Until Medicare | Credit only if 2026 household income is from 100% to 400% of the poverty line, and only on a joint return |
| Her own employer plan, if she keeps working | While she is employed | If she is offered affordable, minimum-value coverage and does not enroll, she gets no credit for the rest of that plan year |
| His employer’s retiree coverage, if offered | Set by the plan | Same as COBRA: the credit is blocked only in months she is enrolled |
IRS guidance says a former employee’s family member is treated as eligible for COBRA or retiree coverage only for the months that you are enrolled, so turning down either one keeps marketplace eligibility open. COBRA by itself cannot get her to 65. The 36-month extension applies only when a second qualifying event happens within the first 18 months.
A 400% Income Ceiling Is Back for 2026
The temporary rule that removed the credit’s upper income limit covered only tax years beginning after December 31, 2020, and before January 1, 2026. For 2026, a household whose income tops 400% of the poverty line for its family size is not an applicable taxpayer and gets no credit. Some states have announced extra ACA premium subsidies for 2027.
For the credit, modified AGI is AGI plus tax-exempt interest and the portion of social security benefits that is not taxable. Every 401(k) withdrawal counts in full. The Roth conversion counts too, because the converted amount is included in gross income. Advance credits are reconciled on Form 8962, so a conversion in December can change the credit for every month of that year.
A $60,000 Roth Conversion Adds $9,900 in 2026 Federal Tax
Assumptions: tax year 2026; married filing jointly; federal income tax only (state tax varies); company pension $40,000; no Social Security claimed; spouse not working; standard deduction $32,200; one-year snapshot with no growth rate applied.
| 2026 | Lean year | Spending year | Conversion year |
|---|---|---|---|
| Pension | $40,000 | $40,000 | $40,000 |
| 401(k) withdrawal | $30,000 | $60,000 | $60,000 |
| Roth conversion | $0 | $0 | $60,000 |
| Household income (AGI) | $70,000 | $100,000 | $160,000 |
| Taxable income | $37,800 | $67,800 | $127,800 |
| Federal income tax | $4,040 | $7,640 | $17,540 |
| Top bracket reached | 12% | 12% | 22% |
The pension uses up the standard deduction and the first part of the 10% bracket before any 401(k) dollar is taxed. In 2026, the 22% rate starts above $100,800 for joint filers. Compared with the spending year, the conversion year costs $9,900 more in federal tax.
On one side, the converted money goes into a Roth IRA, which has no required distributions while the owner is alive. On the other, household income rises by $60,000 in a year when the credit depends on income. If that pushes the household past 400% of the poverty line, the credit is gone for the year. All three columns stay below the $218,000 joint income level where 2026 Part B IRMAA surcharges start. The quiet stretch between his last paycheck and when required minimum distributions begin is often the lowest-tax window a couple will ever see again, which is the whole subject of our free Roth conversion guide.
Medicare and RMD Dates Mark Off the Bridge Years
- Before the last day of work: Ask HR whether retiree coverage exists and what COBRA would cost. Check when her employer holds open enrollment.
- First year after: Choose COBRA or a marketplace plan, then plan 401(k) withdrawals around the 400% line.
- His 65th birthday: He moves to Medicare. The 2026 standard Part B premium is $202.90 a month. His income still counts toward her household income on a joint return.
- Her 65th birthday: She moves to Medicare, and the marketplace credit no longer matters.
- Required distributions: The applicable age is 75 for anyone who reaches 74 after December 31, 2032. The years between her Medicare start and his RMDs are conversion years with no premium tax credit at stake.
His Last Day of Coverage Starts a 60-Day Clock
COBRA is the first choice to close. The election period starts no later than the date his coverage ends and must stay open at least 60 days. His election counts for his spouse too unless it says otherwise, and each covered person may make a separate selection. That means she can choose COBRA while he buys a marketplace plan, or the other way around, as long as the election is made before the period ends.
