Can You Delay Medicare If Still Working?

Glass drawbridge paused above a river of light, supported by twenty glowing sapphire pillars — delaying Medicare while still working with qualifying employer coverage

Quick Answer

Yes, if the coverage is from active employment at an employer with 20 or more employees. That coverage permits delaying Part B without penalty, with a Special Enrollment Period available when the employment ends. COBRA and retiree coverage do not qualify.

Working past 65 with employer coverage from active employment, generally at a company with 20 or more employees, allows delaying Medicare Part B with no late penalty. A working spouse's qualifying coverage counts the same way. When the employment ends, a Special Enrollment Period opens for penalty-free enrollment. The rule turns entirely on the word active: COBRA and retiree coverage are not active employment coverage, and months spent relying on them after 65 can accrue toward a lifetime Part B penalty of 10 percent per full 12-month delay.

Plenty of Nevadans work well past 65, and Medicare’s rules genuinely accommodate that — but only through a gate with two specific conditions, and the people who assume instead of verify are the ones who fund the penalty system.

What are the conditions for delaying safely?

Two, and both must hold:

  1. Active employment — the coverage comes from a job someone (the enrollee or a spouse) is currently working, not from a former employer.
  2. Employer size — generally 20 or more employees.

Meet both, and Part B can wait without penalty. Miss either, and the delay quietly accrues toward a lifetime surcharge of 10% per full 12-month period. The most common failure isn’t small employers — it’s coverage that feels employer-based but isn’t active: COBRA and retiree plans do not count, full stop.

What happens when the job finally ends?

A Special Enrollment Period opens, allowing penalty-free Part B enrollment tied to the end of employment. Two clocks start around that moment, and the second one matters more than most people realize: the 6-month Medigap open enrollment window begins with Part B, and it is the one guaranteed chance to buy any supplement with no medical underwriting. Delaying Part B also delays that protected window — which can be a feature, not a bug, for someone planning ahead.

What should be done before deciding to delay?

Verify, in writing, that the employer coverage qualifies — a five-minute conversation with the benefits administrator versus a permanent penalty. Then compare the employer plan’s real cost against Medicare, since group coverage isn’t automatically the better deal after 65. The decision sequence, including where premium-free Part A fits while Part B waits, is laid out in the turning-65 Medicare checklist.

Frequently Asked Questions

What makes employer coverage qualify for delaying Medicare?

The coverage must come from active employment — the enrollee's own job or a spouse's — generally at an employer with 20 or more employees. Size and active-employment status both matter.

Does COBRA allow delaying Medicare without penalty?

No. COBRA is not coverage from active employment, so months on COBRA after 65 count toward the Part B late penalty of 10% per full 12-month delay.

What happens when the job ends after delaying Medicare?

A Special Enrollment Period opens, allowing Part B enrollment without penalty. Acting promptly matters, because the Medigap open enrollment window is tied to the Part B start date.

Should someone delaying Part B still take Part A at 65?

Many people enroll in premium-free Part A at 65 even while delaying Part B, since Part A costs nothing with 40 quarters of work history. Anyone contributing to an HSA should review the interaction first.
