Why South Carolina business owners don’t get the same Medicare flexibility as large employees

If you’re turning 65 and self-employed in South Carolina — whether you’re running your own business, consulting, or working independently — Medicare rules are more straightforward… but less forgiving.

You don’t get the same flexibility as someone working for a large employer.

And if you miss your enrollment window, it can cost you.


The Rule for Self-Employed Individuals

If you are self-employed at 65:

  • Medicare is your primary insurance
  • You are expected to enroll in Part A and Part B
  • Other coverage (like private plans) does not replace Medicare

This applies even if you:

  • Have an ACA (Marketplace) plan
  • Have private insurance through an association
  • Are still earning income

Why Marketplace Plans Don’t Protect You

One of the biggest misconceptions we see:

“I have an ACA plan, so I can delay Medicare.”

Unfortunately, that’s not how Medicare sees it.

Marketplace plans:

  • Are not considered creditable coverage for delaying Part B
  • Do not prevent penalties
  • May leave you exposed if Medicare should have been primary

The Enrollment Window You Can’t Miss

Your Initial Enrollment Period (IEP) is:

  • 3 months before your 65th birthday
  • Your birthday month
  • 3 months after

If you miss it:

  • You may face lifetime penalties
  • You could have gaps in coverage
  • You may have to wait months before coverage starts

The Penalty That Adds Up Fast

If you delay Part B without qualifying coverage:

  • Your premium increases 10% for every 12 months delayed
  • The penalty is permanent

Even a short delay can cost thousands over time.


A Real Scenario We See Often

A self-employed contractor in Columbia turns 65 and keeps his Marketplace plan because it’s familiar.

He skips Medicare.

Two years later:

  • He learns his ACA plan didn’t count for delaying
  • He now has a 20% lifetime penalty
  • He has to wait for enrollment
  • He experiences a coverage gap

All of this could have been avoided with a simple enrollment at 65.


What You Should Do If You’re Self-Employed

Step 1 — Plan to enroll in Medicare Parts A and B at 65
Step 2 — Evaluate whether to add:

  • A Medicare Supplement + Part D
  • Or a Medicare Advantage plan

Step 3 — Compare costs vs. your current coverage
Step 4 — Time your transition carefully
Step 5 — Talk to a Medicare agent before making changes


One Important Exception: HSA Contributions

If you have a Health Savings Account (HSA):

  • You must stop contributing before enrolling in Medicare
  • Medicare enrollment (even Part A) can create tax issues if mishandled

This is an area where timing matters.
