You can get Medicare at 65 regardless of whether you work, but if you quit before then, you may lose employer coverage and need to act quickly to avoid gaps

Leaving a job before 65 creates a timing problem: your employer health insurance usually ends within 30 to 60 days, but Medicare does not start until you turn 65. The bridge between those two dates is where most people run into trouble. Your options depend on your age, your spouse's age, and whether you have worked long enough to earn Medicare may be able to access.

If you are 65 or older, you can enroll in Medicare as soon as your employer coverage ends — there is no waiting. If you are younger than 65, you will need to find temporary coverage through COBRA (a continuation of your employer plan), the Affordable Care Act marketplace, Medicaid, or a spouse's plan. Missing the window to sign up for any of these can leave you uninsured and subject to penalties when you eventually do enroll.

Key Takeaways

  • If you are 65 or older when you quit, you can enroll in Medicare when ready; your employer coverage ending is a may have access to event that lets you sign up outside the normal enrollment period.
  • If you are under 65, you have 60 days from the date your employer coverage ends to sign up for COBRA, the ACA marketplace, or another plan, or you will face a gap in coverage.
  • You must have worked and paid Medicare taxes for at least 10 years (40 quarters) to get Medicare Part A without paying a premium; if you have not, you may still be able to buy it.
  • Delaying Medicare enrollment after 65 can result in permanent premium increases for Part B and Part D, so timing your signup matters even if you have other coverage.
  • Your spouse's Medicare status and your household income both affect which coverage options cost the least and which programs you may be able to use.

Enrolling in Medicare at 65 or Older

If you are 65 or older when you leave your job, you can enroll in Medicare right away. You do not have to wait for the standard enrollment period (January 1 to March 31 each year). Losing employer coverage counts as a may have access to life event, which means you can sign up as soon as your coverage ends.

Contact Social Security or visit Medicare.gov to start the enrollment process. You will need your Social Security number, proof of citizenship or legal residency, and information about your current coverage. Social Security will walk you through whether you want Part A (hospital insurance), Part B (medical insurance), or both. Most people enroll in both, though you can choose Part A only if you prefer.

The key timing issue: if you enroll after your employer coverage ends, there may be a gap of a few days or weeks. To avoid this, enroll during your employer's final month of coverage so Medicare starts on the first day of the month after your job ends. Social Security can coordinate the dates with you.

Staying Covered Before 65 If You Quit Early

If you are under 65 and leave your job, your employer health insurance typically ends 30 to 60 days after your last day of work. You have three main options to cover the gap until Medicare starts at 65: COBRA, the Affordable Care Act (ACA) marketplace, or Medicaid (depending on your state and income).

COBRA lets you keep your employer plan for up to 18 months by paying the full premium yourself, plus a 2 percent administrative fee. Your employer must notify you of COBRA rights within 14 days of your coverage ending. You have 60 days from that notice to decide whether to enroll. COBRA is often expensive — you are paying what your employer was paying plus your own share — but it keeps you in the same network and plan you had.

The ACA marketplace (Healthcare.gov or your state's exchange) offers plans at various price levels. If your household income is below 400 percent of the federal poverty line, you may receive tax credits that lower your monthly premium. You can enroll in a marketplace plan as soon as your employer coverage ends, and you have 60 days to do so. Plans start on the first of the month following your enrollment, so timing matters if you want no gap.

Medicaid is available in all states but income limits and coverage rules vary widely. If you lose employer coverage, you may become newly may be able to access for Medicaid in your state. You can explore through your state's Medicaid office or through Healthcare.gov. Medicaid has no enrollment important date — you can explore anytime — but approval can take 30 to 45 days.

The 10-Year Work History Requirement

To get Medicare Part A (hospital insurance) without paying a monthly premium, you must have worked and paid Medicare taxes for at least 10 years, or 40 quarters. A quarter is roughly three months; you can earn up to four quarters per year. If you have worked full-time for 10 years, you almost certainly meet this requirement.

If you have not worked 10 years in the United States, you have two choices: buy Part A out of pocket (the premium varies by how many quarters you have worked), or wait until you reach 65 and enroll anyway, paying the premium. Some people choose to work a few more years to reach 40 quarters and avoid the premium. You can check your work history and quarters earned by creating an account on Social Security's website.

If you are married, you may also be able to get Medicare based on your spouse's work history, even if you have not worked 10 years yourself. This is called spousal Medicare. You must be at least 62 years old and your spouse must be at least 62 and already enrolled in Medicare Part A.

Avoiding Penalties for Late Enrollment

If you do not enroll in Medicare Part B or Part D (prescription drug coverage) when you first become may be able to access at 65, you will pay a permanent penalty for each year you delay. The Part B penalty is 10 percent of the standard premium for each 12-month period you were not enrolled. The Part D penalty is 1 percent of the national average premium for each month you were not enrolled. These penalties stay with you for life, even after you do enroll.

There is one exception: if you have creditable coverage — meaning your employer plan or spouse's plan covers prescription drugs at least as well as Medicare Part D — you can delay Part D enrollment without penalty. You must keep proof that your coverage was creditable (usually a letter from your employer or plan). The same rule applies to Part B if you are still working and covered by your employer's plan.

If you quit your job and lose that creditable coverage, you have 63 days to enroll in Part D without penalty. This is called the special enrollment period. Missing this window means the penalty applies. Keep your employer's coverage letter and the date your coverage ended so you can prove you had creditable coverage if you need to.

Coordinating Medicare With Spouse's Coverage

If your spouse is still working or has employer coverage, you may be able to stay on their plan until you turn 65. This is often cheaper than COBRA or marketplace coverage, especially if your spouse's employer subsidizes the premium. Check with your spouse's benefits office about whether you can remain covered as a dependent after you leave your own job.

If your spouse is already on Medicare, you cannot enroll in their Medicare plan — each person has their own Medicare coverage. However, you can both use the same doctors and hospitals if they accept Medicare. Your spouse's enrollment in Medicare does not affect your coverage options before 65.

If both you and your spouse are under 65 and losing coverage, you may both be able to enroll in the same ACA marketplace plan and receive tax credits based on your combined household income. This is often cheaper than two separate COBRA plans. Use Healthcare.gov to compare options for both of you together.

What Happens to Your Employer Retiree Coverage

Some employers offer retiree health coverage — a plan specifically for people who have retired before 65. If your employer offers this, you may be able to enroll when you leave your job, and it can bridge the gap until Medicare starts. Retiree plans vary widely: some cover only Part B premiums, others cover deductibles and copays, and some are full plans. Ask your employer's benefits office whether you are may be able to access and what the plan covers.

If you have retiree coverage, you must still enroll in Medicare Parts A and B at 65. Your retiree plan will coordinate with Medicare and may become secondary coverage (meaning Medicare pays first). Do not skip Medicare enrollment thinking your retiree plan is enough — you need both.

Frequently Asked Questions

Can I enroll in Medicare before I turn 65 if I quit my job?

No. Medicare enrollment is based on age, not employment status. You can enroll starting three months before the month you turn 65. If you are under 65 and need coverage, you must use COBRA, the ACA marketplace, Medicaid, or another plan until you reach 65.

What if I quit my job and then get rehired within 60 days?

If you regain employer coverage within 60 days, you can usually enroll in a marketplace plan or COBRA and then cancel it once your new employer coverage starts. Some people choose not to enroll in temporary coverage if they know they will be covered again soon, but this is risky if the rehire falls through.

Do I have to enroll in Part B when I turn 65, or can I wait?

You can wait, but only if you have creditable coverage through an employer plan (yours or your spouse's). If you do not have creditable coverage and delay Part B past 65, you will pay a permanent 10 percent penalty. If you have creditable coverage, you have until 63 days after that coverage ends to enroll in Part B without penalty.

Will my Medicare premiums be higher because I quit my job?

Your Part A premium (if you pay one) and Part B premium are based on your age and work history, not on whether you are employed. However, your Part B premium may be higher if your household income is above a certain threshold — this is called income-related monthly adjustment amount (IRMAA). Quitting your job lowers your income, which may actually lower your Part B premium.

What if I do not have 10 years of work history?

You can still enroll in Medicare at 65, but you will pay a monthly premium for Part A. The premium depends on how many quarters you have worked. You can also check whether you may have access to for Medicaid in your state, which may cover costs that Medicare does not. Some people choose to work a few more years to reach 40 quarters and avoid the Part A premium.
