I’m Retiring Soon What Do I Do About Medicare Between Now and My Retirement?

Retirement is one of life’s most significant transitions, but for many, the excitement of newfound freedom is often tempered by the complexity of health insurance. If you are nearing 65 or planning to leave the workforce shortly thereafter, Medicare is no longer a distant concept—it is a critical deadline.

 

Navigating the “bridge” between your employer-sponsored coverage and Medicare requires careful timing to avoid lifelong penalties and gaps in care. Here is exactly what you need to handle between now and your retirement date.

 

1. Identify Your Enrollment Window

Your “when” depends entirely on your current age and employment status. There are two primary pathways to entering Medicare:

  • The Initial Enrollment Period (IEP): If you are retiring at age 65, you have a seven-month window to sign up. This includes the three months before your 65th birthday, your birthday month, and the three months following.

     

  • The Special Enrollment Period (SEP): If you are working past age 65 and have “creditable” coverage through an employer (usually defined as a company with 20 or more employees), you can delay Part B. Once you stop working or the coverage ends, you have an eight-month SEP to enroll without penalty.

     

Pro Tip: To ensure a seamless transition where Medicare starts the very day your work insurance ends, you should aim to sign up one month before you actually retire.

2. Understand the “Parts” of the Puzzle

Medicare isn’t a single plan; it’s a menu. You’ll need to decide how you want to receive your benefits:

  • Part A (Hospital Insurance): Most people get this for $0 premium if they’ve worked 10+ years. Even if you’re still working, many experts suggest signing up for Part A at 65 because it’s free and acts as secondary coverage.

  • Part B (Medical Insurance): This carries a monthly premium ($202.90 standard base in 2026). If you are retiring, you must sign up for this to avoid the 10% annual late enrollment penalty.

     

  • Part D (Prescription Drugs): You need creditable drug coverage. If you don’t choose a Part D plan (or a Medicare Advantage plan that includes it) within 63 days of losing employer coverage, you may face a lifetime penalty.

     

  • Medigap vs. Medicare Advantage: You must choose between Original Medicare + a Medigap (Supplement) plan or a Medicare Advantage (Part C) plan. Medigap offers more flexibility with doctors but higher premiums, while Advantage plans often resemble HMOs/PPOs with lower premiums and extra perks like dental.

3. The HSA Warning

If you have a Health Savings Account (HSA), you must stop contributing to it at least six months before you apply for Medicare (or six months before you retire if you are over 65). Because Medicare Part A coverage can be backdated up to six months, continuing to contribute to an HSA during that look-back period can trigger tax penalties. You can still spend the money in your HSA after enrolling in Medicare, but you can no longer add to it.

 

4. Watch Out for IRMAA

If you were a high earner, be prepared for the Income-Related Monthly Adjustment Amount (IRMAA). Social Security looks at your tax returns from two years ago to determine your Part B and Part D premiums. However, because retirement is a “Life-Changing Event,” you can appeal this higher cost if your income drops significantly after you stop working.
