Medicare does not have an income limit for enrollment
Unlike some government programs, Medicare has no income threshold that prevents you from joining. You can be wealthy or have no income at all — either way, you are may have access to to enroll in Medicare when you turn 65 (or earlier if you have a disability or end-stage renal disease). Income does not determine whether you can get Medicare.
What income does affect is how much you pay for certain parts of Medicare coverage. Your income determines your monthly premiums for Part B (doctor visits) and Part D (prescription drugs), and it can also affect whether you may have access to for programs that help pay those premiums. This is a different question from whether you can join Medicare at all.
Key Takeaways
- Medicare enrollment has no income limit — anyone who meets the age or disability requirement can enroll regardless of how much money they earn or have.
- Your income does determine your Part B and Part D premiums through a system called Income-Related Monthly Adjustment Amounts (IRMAA), which means higher earners pay more.
- If your income is below certain thresholds, you may may have access to for programs like Medicaid or the Low-Income Subsidy that help pay your Medicare costs.
- Income is calculated using your Modified Adjusted Gross Income (MAGI) from two years prior, so 2024 premiums are based on your 2022 tax return.
- Life changes like retirement, marriage, or divorce can lower your income and may allow you to request a premium adjustment mid-year.
How income affects your Part B and Part D premiums
If your income is higher, you pay a surcharge on top of the standard Part B and Part D premiums. This surcharge is called an Income-Related Monthly Adjustment Amount (IRMAA). The Centers for Medicare & Medicaid Services (CMS) sets income thresholds each year, and if your income exceeds them, your premiums rise in tiers.
For 2024, the Part B premium surcharge begins if your Modified Adjusted Gross Income (MAGI) exceeds $97,000 for a single person or $194,000 for a married couple filing jointly. The surcharge increases in steps as your income rises. Part D premiums follow a similar structure, with surcharges kicking in at the same income thresholds. These thresholds change annually, so the amounts that trigger a surcharge in 2025 will differ from 2024.
The income figure used is your MAGI from two years before the year you are paying premiums. So your 2024 premiums are based on your 2022 tax return. This two-year lag means you might not see the effect of a recent income change until the following year.
Low-income programs that reduce Medicare costs
If your income is low, you may may have access to for programs that pay part or all of your Medicare premiums and cost-sharing. These programs have their own income limits, which are set lower than the IRMAA thresholds.
Medicaid is a joint federal-state program that covers Medicare premiums and out-of-pocket costs for people with low income and limited assets. Income limits vary by state, but generally range from about $1,000 to $1,500 per month for a single person. You explore through your state Medicaid office, not Medicare.
The Low-Income Subsidy (LIS) program, also called "Extra Help," helps pay Part D premiums and reduces your out-of-pocket drug costs. The income limit is 150 percent of the federal poverty level, which was about $1,968 per month for a single person in 2024 (the amount changes yearly). You can explore through Social Security or Medicare.
The may have access to Medicare Beneficiary (QMB) program pays your Part B premium and some cost-sharing if your income is below 100 percent of the federal poverty level. The Specified Low-Income Medicare Beneficiary (SLMB) program pays only your Part B premium if your income is between 100 and 120 percent of poverty. Both are run by your state.
How to report income changes during the year
If your income drops significantly — because you retired, lost a job, or had a major life change — you do not have to wait two years for your premiums to adjust. You can request a life-changing event adjustment to lower your IRMAA surcharge when ready.
may have access to events include retirement, loss of income, marriage, divorce, or death of a spouse. You must contact Social Security and provide documentation of the change, such as a letter from your employer confirming your retirement date or a divorce decree. Social Security will recalculate your premiums based on your current-year income estimate.
The adjustment takes effect the month after Social Security approves your request. Keep in mind that if your income rises again later in the year, you may owe back premiums when you file your taxes, so report changes as soon as they happen.
Understanding Modified Adjusted Gross Income (MAGI)
MAGI is not the same as the adjusted gross income (AGI) on your tax return. For Medicare purposes, MAGI includes your AGI plus any tax-exempt interest income (such as interest from municipal bonds). This means you might have a higher MAGI than your reported AGI, which could push you into a higher premium tier.
If you are married and file taxes jointly, both spouses' incomes count toward the household MAGI, even if only one of you is on Medicare. This is important to understand because a working spouse's income can trigger a surcharge on the Medicare beneficiary's premiums.
You can find your MAGI on your tax return, or you can contact Social Security to ask what income they have on file for you. If the income Social Security is using is incorrect, you can provide documentation to correct it.
Income limits for different Medicare programs
| Program | Income Limit (2024) | What It Covers |
|---|---|---|
| Medicare enrollment | No limit | Anyone 65+ can enroll |
| IRMAA surcharge begins | $97,000 (single) / $194,000 (couple) | Part B and Part D premiums increase |
| Low-Income Subsidy (Extra Help) | 150% of poverty (~$1,968/month single) | Part D premiums and drug costs |
| may have access to Medicare Beneficiary (QMB) | 100% of poverty (~$1,312/month single) | Part B premium and cost-sharing |
| Medicaid (varies by state) | $1,000–$1,500/month (varies) | Medicare premiums and out-of-pocket costs |
What to do if your income is near a threshold
If your income is close to an IRMAA threshold or a low-income program limit, small changes matter. A year with unusually high income — from a bonus, inheritance, or sale of property — can push you into a higher premium tier for the following two years. Conversely, retirement or a job loss can lower your income enough to may have access to you for help.
If you are approaching retirement, talk to a tax professional or financial advisor about timing your income in the year you retire. Some people can reduce their MAGI by deferring bonuses, delaying Social Security, or managing investment income. These strategies are not available to everyone, but they are worth exploring if you are close to a threshold.
If you think you may may have access to for a low-income program, contact your state Medicaid office or Social Security to learn the exact income limits in your state and what documents you need. Many people do not realize they may have access to, and these programs can save hundreds of dollars per month.
Frequently Asked Questions
Can I be denied Medicare because my income is too high?
No. Medicare has no income limit for enrollment. You can enroll at 65 regardless of how much you earn. Higher income only means you pay higher premiums for Part B and Part D — it does not prevent you from joining.
If I retire mid-year, when does my premium adjustment take effect?
If you report your retirement to Social Security with proof (such as a letter from your employer), they can adjust your IRMAA surcharge effective the month after approval. You do not have to wait until the next calendar year. The adjustment is based on your estimated income for the current year, not your previous year's tax return.
Does my spouse's income count toward my Medicare premiums?
Yes, if you file taxes jointly. Both spouses' incomes are combined into household MAGI for Medicare premium purposes, even if only one of you is enrolled in Medicare. If you file separately, only your individual income counts.
What is the difference between MAGI and the income on my tax return?
MAGI includes your adjusted gross income (AGI) plus tax-exempt interest income, such as interest from municipal bonds. This means your MAGI can be higher than your reported AGI, which could trigger a higher Medicare premium surcharge even if your AGI is below the threshold.
If I may have access to for Medicaid, do I still need to pay Medicare premiums?
Medicaid can pay your Medicare premiums for you if you may have access to for a program like QMB or SLMB. You would still be enrolled in Medicare, but Medicaid covers the cost. You would explore to your state Medicaid office to see which program you may have access to for.
