Can I delay Medicare if I am still working at 65?
Usually yes, if you have health coverage through your own or your spouse's current employer and that employer has 20 or more employees. In that case you can delay Part B without penalty, and a Special Enrollment Period protects you when the job or the coverage ends.
The employer size test is the hinge. At companies with 20 or more employees, the employer plan pays first and Medicare can wait. At smaller companies, Medicare is designed to pay first, which means skipping enrollment can leave you dangerously underinsured even though you feel covered. Many people also choose to take Part A at 65 regardless, since for most people it carries no monthly cost, though anyone contributing to an HSA needs to pause and plan first, because Part A enrollment ends HSA eligibility.
Does COBRA count as employer coverage?
No, and this is the mistake that hurts the most people. COBRA is not considered current employer coverage for Medicare's purposes. If you leave work and take COBRA past 65 without enrolling in Medicare, you can face gaps in coverage and late enrollment penalties that never expire.
The trap is understandable: COBRA looks and feels like your old employer plan, so people assume the same Medicare rules apply. They do not. Your eight month Special Enrollment Period starts when your employment ends, not when your COBRA ends. Retiree coverage follows similar logic. If you are anywhere near this situation, get your dates confirmed before you sign anything.

When exactly should I enroll after I stop working?
Your Special Enrollment Period runs for eight months after your employment or employer coverage ends, whichever comes first. Enrolling before your job coverage actually ends is the cleanest path, because it lets your Medicare start the moment the employer plan stops, with no gap in between.
Treat your retirement date as a project with a lead time. Sixty to ninety days out is the sweet spot to begin: confirm your Part A and B start dates, choose your coverage road, and line up drug coverage so nothing lapses. Waiting until after the retirement party works legally, but it risks weeks without coverage and rushed decisions. The people who feel calm through this transition are simply the ones who started early. That can be you.
What penalties am I actually avoiding?
Late enrollment penalties in Medicare are not one time fees. They are permanent surcharges added to your monthly costs for as long as you have that coverage, and they grow with each year you delay without qualifying coverage. Avoiding them entirely is the whole reason timing matters.
Both Part B and drug coverage carry their own late enrollment penalties, each with its own clock and its own rules about what counts as qualifying coverage. The details matter less than the principle: these penalties are permanent, they are avoidable, and avoiding them requires nothing but enrolling at the right time for your situation. Every situation has a right time. Finding yours is a short conversation, and it is the single highest value ten minutes in all of Medicare planning.
