Can I delay Medicare Part B if I’m still working? The answer is yes for many people, but not everyone.

After helping Medicare beneficiaries since 1985, I’ve found that this is one of the most misunderstood areas of Medicare. I’ve helped many people avoid unnecessary Part B premiums, late enrollment penalties, and costly mistakes simply by understanding how Medicare works with employer coverage.

Whether you can safely delay Medicare Part B depends on the size of your employer, the type of coverage you have, and whether that coverage is considered creditable.

When Can You Delay Medicare Part B?

Many people who continue working after age 65 can delay Medicare Part B without facing penalties.

In general, if you’re covered by an employer group health plan through active employment and the employer has 20 or more employees, you may qualify to postpone Part B.

This can help you avoid paying a monthly Part B premium that you may not need while your employer coverage remains primary.

What If Your Employer Has Fewer Than 20 Employees?

This is where many people get into trouble.

If your employer has fewer than 20 employees, Medicare generally becomes your primary insurance at age 65.

In many situations, failing to enroll in Medicare Part B when first eligible can lead to:

  • Gaps in coverage
  • Unexpected medical bills
  • Lifetime Part B penalties

This is why it’s important not to assume that delaying Part B is always the right decision.

What Is a Medicare Part B Penalty?

If you delay Medicare Part B when you shouldn’t have, you may face a late enrollment penalty.

In most cases, the penalty increases your Part B premium by 10% for each full 12-month period that you were eligible but did not enroll.

Even worse, the penalty can last for as long as you have Medicare Part B.

Avoiding this mistake starts with understanding whether your employer coverage allows you to delay enrollment.

What About COBRA Coverage?

Many people mistakenly believe COBRA allows them to delay Medicare Part B.

Unfortunately, COBRA is generally not considered active employer coverage for Medicare enrollment purposes.

If you rely solely on COBRA and delay Part B, you could face penalties and gaps in coverage.

This is one of the most common Medicare mistakes I see.

Can I Delay Part B If I Have an HSA?

Possibly.

If you’re contributing to a Health Savings Account (HSA), delaying Medicare enrollment may allow you to continue making HSA contributions.

However, enrolling in any part of Medicare generally means you can no longer contribute to an HSA.

Because HSA rules can be complicated, this is another situation where individualized guidance can be valuable.

What Happens When I Retire?

If you’ve delayed Medicare Part B because you had qualifying employer coverage, you’ll generally qualify for a Special Enrollment Period when your employment ends or your employer coverage stops.

This Special Enrollment Period allows you to enroll in Medicare Part B without a late enrollment penalty.

However, there are deadlines, so it’s important to plan ahead.

Common Mistakes to Avoid

After helping Medicare beneficiaries since 1985, I’ve seen the same mistakes repeated time and again.

Assuming All Employer Plans Work the Same

Employer size matters.

Believing COBRA Counts as Employer Coverage

In most situations, it doesn’t.

Ignoring HSA Rules

This can create tax complications.

Missing Enrollment Deadlines

Late enrollment penalties can last a lifetime.
