Medicare for Self-Employed Individuals

If you are self-employed and approaching 65, Medicare works differently for you than it does for people with employer-sponsored coverage. There is no HR department to guide you, no automatic enrollment through a payroll system, and no employer contributing to your premiums. Here is everything a self-employed person needs to know to get Medicare right.

How Medicare Is Different for the Self-Employed

When you are self-employed — whether you run a business, work as a freelancer, operate as an independent contractor, or own a farm — you are responsible for your own health coverage in a way that employees simply are not. You have likely been purchasing private health insurance or marketplace coverage out of pocket for years. Medicare changes that picture significantly at age 65 — usually for the better.

The most important distinction for self-employed people is this: you have no employer plan that qualifies you to delay Medicare. Unlike an employee at a large company who can safely put off Part B while their employer plan covers them, a self-employed person generally has no coverage that allows for a penalty-free delay. When you turn 65, you need to enroll in Medicare during your Initial Enrollment Period — or face permanent late enrollment penalties.

Why Medicare Is Usually Good News for the Self-Employed

If you have been self-employed and paying for individual health insurance out of pocket, you already know how expensive it can be — especially as you approach 60 and 65, when individual market premiums can reach $1,000 to $2,000 or more per month depending on your coverage level and health history.

Medicare typically represents a significant cost reduction for self-employed people. Here is what that shift looks like:

Enrollment Rules for Self-Employed People at 65

Because you have no qualifying employer coverage, the enrollment rules for self-employed people are straightforward — but the consequences of missing them are not.

Your Initial Enrollment Period

Your Initial Enrollment Period (IEP) is a seven-month window centered around your 65th birthday — three months before, your birthday month, and three months after. This is your primary window to enroll in Parts A and B without penalty. Enrolling in the first three months before your birthday month ensures your coverage starts the first day of your birthday month with no gap.

Marketplace Coverage Does Not Protect You

This is one of the most important things for self-employed people to understand. If you are currently covered by an ACA Marketplace plan — even a comprehensive, high-quality plan — that coverage does not qualify as the type of employer coverage that allows you to delay Medicare without penalty. Once you turn 65 and become eligible for Medicare, you must enroll during your IEP or face permanent late enrollment penalties on Part B and Part D.

Additionally, once you are eligible for Medicare, your eligibility for premium tax credits on Marketplace plans ends. If you continue a Marketplace plan past your Medicare eligibility date without enrolling in Medicare, you may be required to repay subsidies you received after your 65th birthday.

The Late Enrollment Penalties — Why Timing Matters So Much

For self-employed people who miss their Initial Enrollment Period, the penalties are real and permanent:

Choosing Your Medicare Coverage — What Self-Employed People Should Consider

Once you are enrolled in Parts A and B, you choose how to fill in the gaps — either through a Medicare Supplement (Medigap) plan or a Medicare Advantage plan. For self-employed people, there are some specific considerations worth thinking through:

The Case for Medigap — Freedom and Predictability

Many self-employed people have spent their careers valuing independence — the ability to choose their own doctors, work on their own terms, and make their own decisions. Medigap aligns with that mindset. With Original Medicare and a Medigap plan you can see any Medicare-accepting provider anywhere in the country — no network, no referrals, no gate-keeping. Your costs are predictable month to month regardless of how much care you use.

This is particularly appealing for self-employed people who travel frequently, consult across multiple cities or states, or who have established relationships with specific specialists they do not want to lose when they change insurance.

The Case for Medicare Advantage — Lower Monthly Cost

If cash flow is a priority — which it often is for the self-employed, especially those winding down a business or transitioning to retirement — Medicare Advantage’s lower monthly premiums can be genuinely attractive. A $0-premium Medicare Advantage plan cuts your monthly health care cost to just the Part B premium, which can free up meaningful cash flow compared to Medigap.

The trade-off is network restrictions and variable out-of-pocket costs at each visit. For self-employed people who stay local, use care moderately, and are comfortable reviewing their plan annually during AEP, Medicare Advantage can be an excellent value.

The Medigap Open Enrollment Window — Do Not Miss It

When you enroll in Part B for the first time at 65, you enter a six-month Medigap Open Enrollment Period during which insurance companies must sell you any Medigap plan at the best available rate — regardless of your health history. After this window closes, in Texas, insurers can use medical underwriting to deny coverage or charge higher premiums based on your health.

For self-employed people who have had health challenges over the years — which is common when you have been on individual market insurance without robust benefits for decades — this open enrollment window may be your only opportunity to lock in Medigap coverage at a standard rate. Missing it by defaulting to Medicare Advantage initially could make switching to Medigap later very difficult or impossible.

The Self-Employed Medicare Premium Tax Deduction

One meaningful financial benefit for self-employed people on Medicare is the ability to deduct Medicare premiums as a business expense. Under IRS rules, self-employed individuals who are not eligible for employer-sponsored health coverage through a spouse’s employer can generally deduct 100% of their Medicare premiums — including Part B, Part D, and Medigap premiums — as an above-the-line deduction on their federal tax return.

This deduction is taken on Schedule 1 of your Form 1040 and reduces your adjusted gross income — making it available regardless of whether you itemize. The deduction applies to:

• Medicare Part B premiums ($185/month in 2026)
• Medicare Part D premiums
• Medicare Supplement (Medigap) premiums
• Medicare Advantage plan premiums (if any)

Still Running Your Business After 65 — What You Need to Know

Many self-employed people in the Rio Grande Valley continue running their businesses well past age 65 — and that is entirely compatible with Medicare. Here is what to keep in mind if you plan to keep working:

Medicare as Your Primary Insurance

Once you are enrolled in Medicare, it becomes your primary insurance. Any other individual coverage you may have had — a marketplace plan, a private plan — should be dropped when Medicare begins. Keeping both creates confusion about which pays first and can result in claims being denied or delayed by both payers.

No Employer Plan to Coordinate With

Unlike employees at large companies who can coordinate Medicare with their employer plan, self-employed individuals typically have no secondary employer coverage. Your Medicare plus whatever supplemental plan you choose — Medigap or Medicare Advantage — is your complete coverage picture.

Employees Working for You

If you have employees working for you and you offer them a group health plan, that group plan’s interaction with Medicare depends on the number of employees you have — the same 20-employee rule that applies to all employers. If you have fewer than 20 employees and you personally are enrolled in Medicare, Medicare is your primary insurance regardless of whether you also participate in your own group plan.
