Working Past 65? Here’s When You Actually Need to Sign Up for Medicare
Are you approaching your 65th birthday but have no plans of slowing down? If you’re like many of our friends and neighbors here in Merced County, you might be wondering if you’re required to sign up for Medicare the moment you blow out the candles.
The short answer is: it depends.
Many people think 65 is a "hard deadline" for everyone, but if you (or your spouse) are still working and have health insurance through that job, the rules change significantly. In simple terms, you have choices: but making the wrong one can lead to unexpected bills and lifetime late enrollment penalties.
At Peace & Grace Insurance Services, we’ve helped thousands of California families navigate these exact transitions with compassion and clarity. Let’s break down the Medicare enrollment rules for 2026 so you can keep working with total peace of mind.
The "20-Employee Rule": Your First Critical Step
Before you do anything else, you need to find out the size of the company providing your insurance. Why does this matter? Because it determines who pays your medical bills first.
- If the company has 20 or more employees: Your employer group health plan is the primary payer. This means they pay your claims first, and Medicare (if you choose to enroll) would be secondary. In this scenario, most people can safely delay Medicare Part B without a penalty.
- If the company has fewer than 20 employees: Medicare typically becomes the primary payer. This is a potential trap! If you don’t sign up for Medicare at 65, your employer’s insurance might refuse to pay their portion, assuming Medicare should have covered it first. This could leave you with massive unexpected bills.
Common Misconception: Many people assume that because they have "good insurance" at a small local shop or family business, they don’t need Medicare yet. The reality is that for small businesses, Medicare is almost always required to avoid coverage gaps.
Medicare Part A: Usually a "No-Brainer"
Medicare Part A covers hospital stays. For most Americans, it is premium-free if you or your spouse have worked and paid Medicare taxes for at least 10 years (40 quarters).
Because it’s usually free, most people sign up for Part A during their Initial Enrollment Period (the 7-month window around their 65th birthday), even if they are still working.
The One Big Exception (HSA Alert):
If you are contributing to a Health Savings Account (HSA) through your employer, you should not sign up for any part of Medicare. Once you enroll in Medicare, you can no longer contribute to an HSA. Doing so could result in tax penalties.
The Medicare Part B Decision: When to Delay
Medicare Part B covers doctor visits and outpatient care, and it comes with a monthly premium (which is $185.00 for most people in 2026, though this can vary based on income).
If you have "creditable" coverage through a large employer (20+ employees), you can often delay Part B. This saves you the monthly premium while you’re still covered by your work plan.
What is "Creditable Coverage"?
In simple terms, this is insurance that Medicare considers to be as good as or better than their own. If your current work insurance is creditable, you won't be penalized for joining Medicare later.
Warning: COBRA and retiree health plans are NOT considered "current employment" coverage. If you are on COBRA and turn 65, you must sign up for Part B, or you will likely face a permanent 10% late enrollment penalty for every year you waited.
Don’t Forget Part D: The Prescription Drug "Trap"
Even if you delay Part B, you must ensure you have creditable prescription drug coverage. Most large employer plans include this, but you should receive a "Notice of Creditable Coverage" from your HR department every year.
If you go more than 63 days without creditable drug coverage after you turn 65, Medicare will add a late enrollment penalty to your premium for as long as you have the plan. These small percentages add up over a lifetime!
How to Transition When You Finally Retire
Whenever you decide to finally "hang up the hat," you’ll have an 8-month Special Enrollment Period (SEP) to sign up for Medicare without any penalties.
We recommend starting this process about 2 to 3 months before you stop working. This ensures your Medicare starts the very day your work insurance ends, so there is never a day you are unprotected.
