Is there a penalty for not taking Medicare at 65?

Editorial team Published on

The penalty for not signing up for Medicare at age 65 depends on the specific part of Medicare (Part A, Part B, or Part D) and whether you have qualifying employer coverage. You can learn more through the official Medicare Costs and Penalties Guide.

Medicare Part A Penalty (Hospital Insurance)

  • The Penalty: Your monthly premium increases by 10%.
  • Duration: You pay this higher amount for twice the number of years you delayed signing up.
  • Who it affects: Most people get Part A for free because they paid Medicare taxes while working, meaning they face no penalty. It only applies if you have to buy Part A.

Medicare Part B Penalty (Medical Insurance)

  • The Penalty: Your monthly premium goes up by 10% for each full 12-month period you delayed enrollment without other coverage. In 2026, the standard Part B premium is $202.90, making the penalty 10% of that base for each year delayed.
  • Duration: You pay this surcharge for as long as you have Part B (usually for life).

Medicare Part D Penalty (Prescription Drug Coverage)

  • The Penalty: An extra 1% of the national base beneficiary premium ($38.99 in 2026) is added for every full month you went without Part D or other creditable prescription drug coverage.
  • Duration: This amount is added to your monthly bill for as long as you have Part D coverage.

How to Avoid Penalties

  • Working past 65: If you or your spouse are actively working and you are covered by an employer group health plan, you can usually delay enrollment without a penalty during a Special Enrollment Period.
  • Creditable coverage: Maintaining health or drug coverage from an employer that meets Medicare standards protects you from late fees. More details on timing rules are available via the Social Security Administration Enrollment Guide.

What is the maximum income to avoid Medicare penalty?

To avoid the income-related Medicare surcharge known as IRMAA (Income-Related Monthly Adjustment Amount), your Modified Adjusted Gross Income (MAGI) must be $109,000 or less for single filers and $218,000 or less for married couples filing jointly in 2026.

Understanding Medicare Income Limits (IRMAA)

  • What it is: IRMAA is an extra charge added to your Medicare Part B and Part D monthly premiums if your income goes over the government limit. It is often referred to as a "penalty" or surcharge on high earners.
  • The look-back period: Medicare checks your federal tax return from two years prior. Your 2026 surcharge is based on your 2024 tax filing.
  • What counts as income: The Social Security Administration looks at your MAGI, which is your Adjusted Gross Income plus any tax-exempt interest income (such as interest from municipal bonds).

Tiers and Thresholds

If you earn even $1 over the base threshold, you enter the first surcharge bracket, which adds an extra monthly fee to both Part B and Part D. The brackets scale up with higher income levels, topping out for individuals making $500,000 or more and joint filers making $750,000 or more.

How much will Medicare cost me once I turn 65?

When you turn 65, your minimum standard cost for Medicare will be $202.90 per month. However, Medicare is not entirely free, and your final out-of-pocket costs will depend on your work history, your income, and the supplemental plans you choose.

An overview of what you will pay based on the official Centers for Medicare & Medicaid Services (CMS) rates outlines the primary costs:

1. The Core Components (Original Medicare)

  • Part A (Hospital Insurance): $0 per month for most people. If you or your spouse worked and paid Medicare taxes for at least 10 years (40 quarters), you do not pay a premium. If you use it, there is a $1,736 deductible per hospital benefit period.
  • Part B (Medical/Outpatient Insurance): $202.90 per month (standard premium). This is required for anyone on Medicare. There is also an annual $283 deductible, after which you typically pay 20% of your doctor visits and outpatient care costs.

2. High-Income Adjustments (IRMAA)

If your modified adjusted gross income from two years ago (tracked via your tax returns) was higher than $109,000 for a single filer or $218,000 for a married couple filing jointly, you will pay an extra surcharge known as IRMAA. Your total Part B premium could range from $284.10 to $689.90 per month depending on your exact bracket.

3. Essential Add-Ons (What Most People Actually Choose)

Because Original Medicare has no maximum out-of-pocket limit, most 65-year-olds choose one of two pathways to control their healthcare expenses:

Path OptionsEstimated Monthly CostWhat You Get
The Supplemental Route
(Original Medicare + Medigap + Part D)		$388 – $458 / month• Part B: $202.90
• Part D (Drugs): ~$35 average premium
• Medigap (e.g., Plan G): ~$150–$220 (covers your 20% co-insurance and deductibles).
The Medicare Advantage Route
(Part C)		$203 – $250 / month• Part B: $202.90
• Part C Plan Premium: Often $0 or a very low monthly fee. Combines medical, hospital, and drugs into one network-based plan with a set annual out-of-pocket maximum.

Note: If you plan to enroll in 2027, the standard Part B premium is projected to increase slightly to $209.50 per month and the annual Part D drug out-of-pocket limit will rise to $2,400. Final rates for 2027 will be finalized by CMS in late fall.

Why would someone over 65 not have Medicare?

Someone over 65 might not have Medicare because they are still working with employer health coverage, lack the required work history for premium-free Part A, or do not meet U.S. residency rules.

Working and Employer Coverage

  • Active employment: If you or your spouse are still working and have a group health plan from an employer with 20 or more employees, you can delay Medicare without penalties.
  • Cost savings: Some choose to stay on a comprehensive employer plan instead of paying extra for Medicare parts. You can learn more about rules for Working Past 65.

Work History and Eligibility Barriers

  • Insufficient tax contributions: To get premium-free Part A (hospital insurance), you or your spouse must have worked and paid Medicare taxes for at least 10 years (40 quarters).
  • High buy-in costs: People who lack this work history can buy into Medicare, but the monthly premiums are expensive, leading some to choose alternative coverage like the Affordable Care Act Marketplace.

Citizenship and Residency Rules

  • Residency requirements: Non-citizens must be permanent legal residents and live in the U.S. continuously for at least five years before they can apply for Medicare.
  • Recent immigrants: Sponsored parents or newly arrived family members often do not meet these strict timelines when they turn 65.

Administrative and Financial Loss

  • Unpaid premiums: If someone has to pay a monthly premium for Part A or Part B and fails to pay, their coverage can be canceled.
  • Missed enrollment: Missing the Initial Enrollment Period and failing to qualify for a Special Enrollment Period can result in delayed sign-ups or coverage gaps.

Why would someone opt out of Medicare?

A healthcare provider might opt out of Medicare to set their own fees through private contracts and avoid government billing rules.

Key Reasons for Opting Out

  • Direct Primary Care (DPC): Providers use monthly membership models. Opting out prevents conflicts with Medicare rules on charging for covered services.
  • Set Custom Fees: Doctors can charge patients directly what they deem appropriate rather than accepting fixed Medicare reimbursement rates.
  • Reduce Bureaucracy: Providers escape complex paperwork, audits, and billing regulations from the Centers for Medicare & Medicaid Services (CMS).
  • More Time with Patients: Freedom from volume-based constraints allows doctors to spend more time per visit.

How It Works

  • Private Contracts: Patients sign an agreement to pay out-of-pocket without submitting claims to Medicare.
  • Two-Year Commitment: The opt-out status lasts for two years and auto-renews unless canceled.
  • Global Status: The provider cannot bill Medicare for any patient, including via Medicare Advantage plans.

Does Medicare check your income every year?

Yes, Medicare checks your income every year to see if you must pay an extra charge called IRMAA (Income-Related Monthly Adjustment Amount).

How Annual Income Checks Work

  • Two-year lookback: The Social Security Administration (SSA) looks at your federal tax return from two years prior to determine your current year's premiums. For example, your income from two years ago dictates your costs for Part B (medical insurance) and Part D (prescription drug coverage).
  • Automatic review: The SSA checks your tax data with the IRS every year without you needing to reapply.
  • Sliding brackets: If your Modified Adjusted Gross Income (MAGI) goes above set limits (starting at $109,000 for single filers or $218,000 for married couples filing jointly), you pay a higher monthly premium. If your income drops or rises later, your surcharge updates in a future year to match that new two-year-old tax data.

Changing Your IRMAA

  • Life-changing events: If your income drops because of a major life event—like retirement, marriage, divorce, or the death of a spouse—you can ask the SSA to use your current lower income instead of waiting two years.
  • Appeals: You can file an appeal using Form SSA-561 if your recent tax data does not reflect your true current financial state.

What is the big mistake people make with Medicare?

The single biggest and most costly mistake people make with Medicare is missing enrollment deadlines, leading to permanent late-enrollment penalties and gaps in coverage.

Missing Enrollment Deadlines

  • Initial Enrollment Period (IEP): This window lasts for seven months. It starts three months before the month you turn 65, includes your birthday month, and ends three months after.
  • Late Penalties: Failing to sign up for Part B or Part D on time can trigger permanent monthly or yearly financial penalties added to your premiums.
  • Delayed Enrollment Confusion: Many people wrongly assume they can delay Medicare past age 65 just because they have health coverage like COBRA, a marketplace plan, or small-employer insurance.

Other Costly Medicare Mistakes

  • Ignoring Annual Changes: Sticking with automatic renewal without reading the Annual Notice of Change (ANOC) can result in unexpected costs, as drug lists and doctor networks shift every year.
  • Choosing Solely by Low Premiums: Picking a plan based only on a low monthly cost while ignoring total out-of-pocket expenses like deductibles, copays, and coinsurance.
  • Missing the Medigap Window: Forgetting to apply for a Medigap (Medicare Supplement) policy during your open enrollment window. After this six-month period, insurers can use medical underwriting to charge more or deny coverage.
  • Skipping Financial Assistance: Overlooking programs like Medicare Savings Programs or Part D Extra Help that assist with out-of-pocket medical and prescription expenses.

What happens if I don't take Medicare when I turn 65?

If you do not sign up for Medicare when you turn 65, you may face permanent late-enrollment penalties and gaps in health coverage, unless you have qualifying coverage through a current job.

When You Can Delay Without Penalties

You can safely delay Medicare past age 65 if you or your spouse are actively working and you have group health coverage through an employer with 20 or more employees.

  • If your employer has fewer than 20 employees, you generally must sign up for Medicare at 65 because Medicare becomes your primary insurance.
  • COBRA and retiree health plans do not count as active employer coverage to avoid Part B penalties.
  • You must have creditable prescription drug coverage (coverage that pays at least as much as Medicare's standard plan) to avoid a Part D penalty.

What Happens If You Delay Without Qualifying Coverage

If you miss your 7-month Initial Enrollment Period (the 3 months before, the month of, and the 3 months after your 65th birthday) without valid work coverage, the consequences include:

  • Part B Late Penalty: Your monthly Medicare Part B premium increases by 10% for every full 12-month period you delayed signing up. You pay this extra amount for the rest of your life.
  • Part D Late Penalty: Your monthly prescription drug premium increases by 1% of the national base beneficiary premium for every month you went without creditable coverage. This is also a permanent addition to your bill.
  • Part A Late Penalty: If you have to pay a monthly premium for Part A (because you or your spouse didn't work long enough to earn premium-free Part A), your monthly premium goes up by 10% for twice the number of years you delayed.
  • Coverage Gaps: If you miss your enrollment window, you may have to wait for the General Enrollment Period (January 1 through March 31), meaning your coverage won’t begin until July 1, leaving you uninsured for months.

Which Medicare plan is free at age 65?

Medicare Part A (Hospital Insurance) is free (has a $0 monthly premium) for most people when they turn 65.

How to Qualify for Free Part A

You get premium-free Part A if you or your spouse paid Medicare taxes while working for at least 10 years (or 40 work quarters).

What Isn't Free

While Part A is premium-free for eligible workers, other parts of Medicare require monthly payments and out-of-pocket costs:

  • Part B (Medical Insurance): Covers doctor visits and outpatient care, but requires a standard monthly premium.
  • Part C (Medicare Advantage) & Part D (Prescription Drugs): Offered by private companies and usually charge separate monthly premiums.
  • Deductibles & Copays: Even with free Part A, you still pay deductibles (such as the hospital inpatient deductible) when you receive care.

You can read more about what is covered at no cost through What Medicare Is Free for Seniors or review specific 12 Free Medicare Services provided by wellness and preventive care.

Can I have both Social Security and Medicare?

Yes, you can receive both Social Security and Medicare at the same time.

How They Work Together

  • Separate Programs: Social Security provides monthly cash income for retirement or disability, while Medicare provides federal health insurance.
  • Simultaneous Receipt: Most eligible people aged 65 or older (or those with qualifying disabilities) get both programs at the same time.
  • Automatic Enrollment: If you are already collecting Social Security benefits when you turn 65, you are automatically enrolled in Medicare Parts A and B.
  • Premium Deductions: If you receive Social Security benefits when you enroll in Medicare, your Medicare Part B (medical insurance) premiums are usually deducted directly from your monthly Social Security check.

Key Rules

  • Different Age Triggers: You can claim early Social Security retirement benefits starting at age 62, but standard Medicare eligibility does not begin until age 65 (unless you qualify early due to a disability).
  • Independent Choices: You can delay taking Social Security benefits past age 65 while still signing up for Medicare at age 65, though you will have to pay your Medicare premiums directly rather than through a deduction. You can visit the Social Security Administration to manage your options.
