Turning 65 with an Employer Plan, an HSA, and a Younger Spouse
Robert turns 65 in two months. He works full time for a firm with 40 employees and is enrolled in its PPO; his wife, 62, is covered as a dependent. He earns $92,000 and contributes $6,000 a year to the HSA linked to the firm's high-deductible plan. An agent tells him he must “sign up for Parts A and B right now or pay a lifetime penalty,” and separately advises him to drop the group plan and buy a Marketplace plan with a subsidy. Robert plans to keep working until 68. He also has not yet filed for Social Security.
1. Is the agent right that Robert must enroll in Medicare now? Address Part A, Part B, and the employer's size.

No - the agent is wrong, and the size of the employer is the reason.
- 40 employees means the employer is a large group for Medicare purposes (20 or more). Robert is an active employee, so the group PPO is primary and Medicare is secondary. Medicare is not needed to have coverage.
- Part B can be delayed without penalty while he is covered by a group plan based on current employment. When he retires at 68 he gets a Special Enrollment Period: he may enroll any time while still covered, or during the 8 months after that coverage ends.
- Part A is usually premium-free, but it is not free of consequences - see the HSA question.
- The automatic-enrollment trap: if he files for Social Security at 65 or later, he is typically auto-enrolled in both A and B, whether he wanted B or not. Since he has not filed, he still has control. If he does not want Part B yet, he should not file for Social Security at this point.
So the advice inverts: doing nothing right now is a legitimate, penalty-free choice, provided he stays actively employed and covered.
2. Robert contributes $6,000 a year to his HSA. What happens to that contribution when he enrolls in Medicare, and how should that shape the Part A decision?

The rule: HSA eligibility requires enrollment in a qualifying high-deductible health plan and no disqualifying coverage. Medicare is disqualifying coverage - any part of it, including premium-free Part A.
Consequence: contributions must stop as of the month Medicare entitlement begins. Contributions made after that are excess contributions: taxable, and subject to a 20% excise tax if not corrected. He cannot simply keep contributing until tax time; the fix is a timely withdrawal of the excess and earnings.
Proration: because entitlement is by month, a partial-year contribution limit applies - he gets 1/12 of the annual limit for each month he is HSA-eligible. If he enrolls mid-year, the last-month rule for full-year contributions does not rescue him unless he stays eligible through the testing period.
The judgment call: Part A now (to be “set up”) costs him the ability to contribute $6,000 pre-tax and, depending on his tax bracket, roughly $1,300–$2,000 in tax savings a year for the next three years. Part A is not needed while he is actively employed at a 40-employee firm. Delaying Part A until retirement preserves the HSA.
One caveat: Part A enrollment can be backdated up to six months in some situations - if he is auto-enrolled retroactively, HSA contributions for those months are excess too.
3. Evaluate the Marketplace suggestion. Then explain what Robert and his wife should do at 68 when he retires, including the Part B deadline and the wife's options.

Marketplace advice is wrong on the subsidy. A premium tax credit is available only if he lacks access to affordable employer coverage. He has an employer plan offered; dropping it voluntarily does not create eligibility, and he would also lose the employer contribution and the HSA. He would pay more for less.
At retirement (age 68):
- Part B - the 8-month clock. His SEP runs 8 months from the date group coverage ends. Miss it and he enrolls in the next general enrollment period with a 10% premium surcharge for each full 12 months he was eligible but not enrolled - for life. Because he had active employment coverage, this does not apply while he worked, but it starts the moment he stops.
- COBRA is not current-employment coverage. If he takes COBRA for 18 months and assumes it protects him from the penalty, he is wrong - COBRA does not extend the SEP. He would owe a penalty for those months. Enroll in Part B when the group plan ends and let COBRA (or a supplement) fill the gap.
- Part D. He will need creditable prescription coverage; if he goes without for 63+ days after Part B starts, he pays a permanent late-enrollment penalty.
- Wife, 62. She cannot get Medicare. Her options are COBRA for up to 36 months, a Marketplace plan (a genuine subsidy opportunity here - the household is losing employer coverage, which is a qualifying event), or a private individual policy. COBRA is usually the most expensive of the three; compare it against a subsidized Marketplace plan before electing.
Sequence matters: confirm the group coverage termination date in writing, enroll in Part B inside the 8 months, arrange the wife's coverage at the same time, and keep records of the employer coverage - he will need them if the penalty is ever assessed.
