Should I Keep My Employer Health Insurance When I Retire?

Should you keep your employer health insurance when you retire? The short answer: it depends on your age, Medicare eligibility, coverage quality, and costs. Many Americans find that employer-sponsored retiree health insurance can fill valuable gaps in Medicare—but others pay more than necessary for coverage they barely use. Understanding how these plans work with Medicare and your retirement income strategy is essential before making the call.

Understanding Employer Health Insurance After Retirement

Employer health insurance is often a major part of your total compensation, and some lucky retirees get to keep it even after they leave the workforce. These plans, known as retiree health benefits, vary widely—some offer full coverage until Medicare kicks in, others only offer supplemental coverage, and many are disappearing altogether as companies cut costs.

In the U.S., about 32% of employers still offer some form of retiree health insurance, according to the Mercer. For example, you might have access to a group plan that continues into retirement or the option to purchase COBRA coverage for up to 18 months after leaving your job.

If you retire before 65, employer coverage can bridge the gap until Medicare eligibility. But if you’re 65 or older, your employer plan likely coordinates with Medicare—and that’s where things can get tricky.

How Employer Coverage Works With Medicare

When you turn 65, you become eligible for Medicare. But if you still have access to employer coverage, who pays first—your employer plan or Medicare?

• If you’re still working: Employer coverage is primary, and Medicare is secondary.
• If you’re retired: Medicare becomes primary, and your employer plan becomes secondary (if it continues at all).

For example, say you’re 66 and covered by your former employer’s retiree plan. Medicare Part A and B will pay first, and your employer plan might help cover deductibles, copays, and prescriptions. However, some employers require you to enroll in Medicare as a condition of keeping your coverage.

Always confirm how your employer plan coordinates with Medicare before you decline or delay any coverage—because missing your Medicare enrollment window could mean lifelong penalties.

Pros of Keeping Employer Health Insurance

Keeping your employer’s health plan can be a big win under the right circumstances. Let’s break down the advantages:

• Comprehensive coverage: Employer plans often include dental, vision, and prescription drug benefits that Medicare doesn’t fully cover.
• Lower out-of-pocket costs: If your employer subsidizes the premiums, you may pay much less than for an individual Medicare Advantage or Medigap policy.
• Family coverage: Retiree health plans can sometimes extend coverage to your spouse, even if they’re not yet Medicare-eligible.
• Convenience: You stay with familiar providers and billing systems you already know.

For example, if your employer pays 70% of your retiree health premium and you pay 30%, it might make sense to keep it—especially if you use dental and drug coverage frequently.

Cons of Keeping Employer Health Insurance

However, not every retiree health plan is a good deal. There are downsides to watch out for:

• High premiums: Once you retire, your employer might stop subsidizing your plan, leaving you to pay the full cost—sometimes over $500 per month per person.
• Limited availability: Some plans end once you turn 65 or require you to enroll in Medicare to maintain coverage.
• Changing terms: Employers can reduce or cancel retiree benefits at any time. According to the Employee Benefit Research Institute (EBRI), only about 10% of private-sector workers are now covered by retiree health plans.
• Double coverage confusion: Overlapping benefits can lead to administrative headaches and wasted money if you’re paying for redundant coverage.

Key Questions to Ask Before You Decide

Before you decide to keep or drop your employer health insurance in retirement, ask these essential questions:

• What portion of the premium will I pay after I retire?
• Does the plan require me to enroll in Medicare?
• Will my spouse or dependents remain covered?
• Can I rejoin the plan later if I drop it now?
• What happens if my employer changes or cancels retiree coverage?

Use these answers to compare against Medicare Advantage or Medigap plans. It’s often wise to use a Retirementize Income Calculator to model how premium costs and healthcare expenses will affect your long-term retirement income.

Comparing Employer Coverage vs. Alternatives

Here’s how to make a smart, side-by-side comparison:

1. List your annual medical expenses.
2. Calculate your out-of-pocket premiums under both your employer plan and potential Medicare options.
3. Check coverage categories: Prescriptions, dental, vision, and travel insurance.
4. Estimate your total 20-year healthcare costs using the Retirementize calculator to see how coverage choices affect your financial future.

For example, if your retiree plan costs $350/month versus a Medicare Advantage plan at $200/month, that’s a $1,800 annual difference—or $36,000 over 20 years. That’s money that could be invested elsewhere in your retirement plan.

What Happens If You Decline Employer Health Insurance?

Deciding to drop your employer coverage isn’t always reversible. Once you opt out, some employers won’t let you back in later. Additionally, you could face Medicare penalties if you delay enrollment without creditable coverage.

Before you decline, consider:

• Is your employer coverage considered “creditable” under Medicare rules?
• Would losing it expose you to high out-of-pocket costs?
• Do you have a spouse or dependents who rely on your plan?

If you’re confident that Medicare and a Medigap plan cover your needs, dropping employer coverage could free up thousands of dollars annually.

The Tax and Financial Planning Angle

Health costs are one of the biggest expenses in retirement—potentially over $315,000 for a couple retiring at 65, according to Fidelity’s 2024 Retiree Health Care Cost Estimate. Employer-sponsored plans often include tax advantages, like premiums paid pre-tax or employer contributions that aren’t taxable income.

If you pay your own premiums, you may be able to deduct medical expenses that exceed 7.5% of your adjusted gross income. These savings can make a difference, especially when combined with strategic withdrawal planning using the Retirementize online income calculator.

Special Cases and Exceptions

Early Retirees (Before 65)

If you retire early, before you’re eligible for Medicare, employer health coverage can be a lifesaver. It helps bridge the gap between employer insurance and Medicare. If it’s not available, COBRA or ACA marketplace plans may fill the void—though they’re usually more expensive.

Spousal Coverage

If your spouse continues working, you might join their employer plan instead, which can offer more flexibility or lower premiums.

Part-Time or Phased Retirement

Some employers allow reduced work hours while maintaining benefits—an ideal scenario if you’re easing into retirement.

Expat Retirees

If you plan to live abroad, your employer coverage may not apply internationally. In that case, you’ll need a global medical insurance policy.

Fun Facts

• Only about 10% of U.S. private-sector retirees have access to employer-sponsored health insurance today.
• Fidelity estimates a typical 65-year-old couple will spend over $315,000 on healthcare in retirement.
• Medicare covers about 80% of medical expenses, but not dental, vision, or long-term care.
• Over 60% of retirees say healthcare is their biggest retirement worry (Transamerica Center for Retirement Studies).
• People with retiree health insurance report higher satisfaction with their retirement quality of life than those without.

How to Decide: A Simple Framework

Here’s a quick framework to help you decide whether to keep your employer health plan:

1. Evaluate coverage: Does it include dental, drugs, and spousal benefits?
2. Compare total costs: Add premiums, deductibles, and out-of-pocket expenses.
3. Assess flexibility: Can you re-enroll later? Does it travel with you?

If your employer plan offers strong coverage and subsidies, it may be worth keeping. But if it’s expensive or overlaps with Medicare, you might save money by switching to a Medigap or Medicare Advantage plan.

Conclusion

Whether you should keep your employer health insurance when you retire depends on your situation, coverage options, and financial goals. If your employer offers generous benefits, it can be a valuable bridge or supplement to Medicare. But if costs outweigh the benefits, other options—like Medicare Advantage or Medigap—might be better.

The key is to model the long-term financial impact. Use the Retirementize Income Calculator to estimate healthcare costs alongside your retirement income, pensions, and savings. A little planning now can prevent big surprises later.
