The 2025 Medicare Part B Premium

The standard Medicare Part B premium for 2025 is $185 per month for most people. This is the amount you pay to Medicare each month to cover doctor visits, outpatient care, lab work, and other medical services that Part A (hospital insurance) does not cover.

However, your actual premium may be higher than $185 if your income was above a certain level two years ago. Medicare uses your 2023 tax return to set your 2025 premium, which means higher earners pay what is called an Income-Related Monthly Adjustment Amount (IRMAA) on top of the standard premium. The more you earned, the more you pay — sometimes significantly more.

You pay Part B premiums whether you receive Social Security or not. If you do receive Social Security, Medicare deducts the premium directly from your monthly benefit. If you do not receive Social Security, you receive a bill from Medicare each month.

Key Takeaways

  • The standard Part B premium is $185 per month in 2025, but yours may be higher if your income in 2023 was above $103,000 (single) or $206,000 (married filing jointly).
  • Income-based surcharges can add $70 to $560 per month to your premium depending on your income bracket.
  • Medicare calculates your premium using your 2023 tax return, so changes in your income or life situation in 2024 do not affect your 2025 premium.
  • You can request a review of your premium if your 2024 income dropped significantly due to retirement, job loss, or other life changes.

Income Brackets and Higher Premiums

If your modified adjusted gross income (MAGI) in 2023 was higher than $103,000 (single filers) or $206,000 (married filing jointly), you will pay more than the standard $185 per month. The surcharge increases in steps as your income rises.

For 2025, the income brackets and surcharges are:

Income (Single)Income (Married Filing Jointly)Monthly SurchargeTotal Monthly Premium
$103,000 or less$206,000 or less$0$185
$103,001–$129,000$206,001–$258,000$70$255
$129,001–$161,000$258,001–$322,000$175$360
$161,001–$193,000$322,001–$386,000$280$465
$193,001 or more$386,001 or more$560$745

These brackets change each year. If you are near the edge of a bracket, even a small increase in income can move you into a higher surcharge tier.

When Your Premium Changes During the Year

Your 2025 premium is locked in based on your 2023 income. Changes you experience in 2024 — such as retirement, the death of a spouse, a job loss, or a large one-time payment like a pension lump sum — do not automatically lower your premium for 2025.

However, you can request a review if your 2024 income dropped significantly. You will need to file a form called the Medicare Income-Related Monthly Adjustment Amount Life-Changing Event form (SSA-44) with Social Security. You must submit it within 60 days of the event that caused your income to drop. If approved, Medicare can adjust your premium retroactively to the month after the event occurred.

Common life-changing events that may have access to for a review include retirement, loss of income-producing property, death of a spouse, divorce, and loss of a job or employer-sponsored health coverage. Inheritance and investment gains do not count as life-changing events.

How Part B Premium Fits Into Your Total Medicare Costs

The Part B premium is only one piece of what you pay for Medicare. You also pay a Part A deductible if you are hospitalized ($1,676 for 2025), copayments for doctor visits and services, and coinsurance for longer hospital stays. If you choose Medicare Advantage (Part C) or add prescription drug coverage (Part D), those have their own premiums and out-of-pocket costs.

Many people reduce their total out-of-pocket costs by enrolling in a Medigap (supplemental insurance) plan, which covers some of the costs that Original Medicare does not. Medigap plans have their own premiums, which vary by plan and insurance company, but they can save you money if you use medical services frequently.

Paying Your Part B Premium

If you receive Social Security, Medicare automatically deducts your Part B premium from your monthly benefit before you receive it. You do not have to do anything — the deduction happens on its own.

If you do not receive Social Security, you will receive a bill from Medicare each month. You can pay by mail, phone, or online through the Medicare website. Set up automatic payments to avoid missing a payment, which can result in a late enrollment penalty if you drop coverage and rejoin later.

If you have trouble paying your premium, you may be able to get help through your state's Medicare Savings Program, which can pay your Part B premium for you. Income limits explore, and the program varies by state. You can learn more by calling 1-800-MEDICARE or visiting Medicare.gov.

What Part B Covers

Your Part B premium covers doctor visits, preventive care (like annual wellness visits and screenings), lab work, X-rays, and outpatient surgery. It also covers durable medical equipment like wheelchairs and oxygen, mental health services, and rehabilitation therapy.

Part B does not cover dental care, vision care, hearing aids, or long-term care. Those services require separate coverage or out-of-pocket payment. If you need those services, you may want to explore Medicare Advantage plans, which sometimes include dental or vision benefits, or purchase standalone plans.

Frequently Asked Questions

Can I lower my Part B premium if my income dropped in 2024?

Yes, if your income dropped significantly due to a life-changing event like retirement or job loss, you can request a review. File the SSA-44 form with Social Security within 60 days of the event. If approved, your premium can be adjusted retroactively.

What happens if I do not pay my Part B premium?

If you miss payments, Medicare will send you notices. If you do not pay, your coverage can be terminated. If you later rejoin Part B, you may owe a late enrollment penalty that increases your premium permanently. Contact Medicare when ready if you are having trouble paying.

Is the Part B premium the same for everyone?

No. The standard premium is $185 per month, but if your income in 2023 was above $103,000 (single) or $206,000 (married), you pay a higher amount based on your income bracket. Your actual premium depends on your tax return from two years prior.

Do I have to pay Part B if I am still working?

If you are covered by your employer's health plan, you may be able to delay Part B enrollment without penalty. However, you still need to enroll in Part A (hospital insurance) at 65. Talk to your employer's benefits office about your options before your 65th birthday.

What is the difference between Part B and Part D?

Part B covers doctor visits and medical services. Part D covers prescription drugs. They are separate, and you pay separate premiums for each. Part D is optional, but if you do not enroll when you first become may be able to access, you may owe a late enrollment penalty.
