Social Security benefits will receive a 2.5% cost-of-living increase in 2025. What will Medicare Part B monthly premiums be in 2025 and when do surcharges apply for higher income beneficiaries?

The Centers for Medicare and Medicaid Services recently announced the cost-of-living adjustments for 2025. While premium and out-of-pocket cost increases will be moderate for most beneficiaries, high income earners will pay significantly more. Here is what you can expect to pay in 2025.

Part B Premium

Medicare Part A, which covers hospital care, is premium-free for most beneficiaries. Medicare Part B, which covers doctor visits and outpatient services, has a monthly premium.

Starting in January, the standard monthly Part B premium will be $185, up from $174.70 in 2024. The $10.30 difference represents an increase of 5.9%, which is more than double the recent Social Security cost-of-living adjustment of 2.5%.

If you are a high-earning beneficiary, a group that comprises approximately 8% of all Medicare recipients, you will have to pay more. Medicare surcharges for high earners, known as the income-related monthly adjustment amount (IRMAA), are based on adjusted gross income (AGI) from two years earlier. This means that your 2025 Part B premiums are determined by your 2023 AGI, which is located on line 11 of Form 1040.

If your 2023 income was from $106,000 to $133,000 ($212,000 to $266,000 for joint filers), your 2025 Part B monthly premium will be $259. For individuals with an income over $133,000 to $167,000 (over $266,000 to $334,000 for joint filers), the monthly premium will rise to $370. Individuals earning more than $167,000 up to $200,000 (more than $334,000 up to $400,000 for joint filers) will see their monthly Part B premium increase to $480.90. Those with incomes above $200,000 up to $500,000 (above $400,000 up to $750,000 for joint filers) will pay $591.90 per month in 2025. Individuals with income more than $500,000 (more than $750,000 for joint filers) will pay $628.90 per month.

Part D Premium

If you have a stand-alone Medicare (Part D) prescription drug plan, the average premium in 2025 will be $46.50 per month for most beneficiaries, down from $53.95 in 2024. For high earners with annual incomes above $106,000 ($212,000 for joint filers), you will pay a monthly surcharge between $13.70 to $85.80 (based on your income level) in addition to your regular Part D premiums.

How to Contest Income

Beneficiaries who fall into any of the high-income categories and have experienced certain life-changing events that have reduced their income since 2023, such as retirement, divorce or the death of a spouse, can contest the surcharge. For more information on how to do this, see “Medicare Premiums: Rules for Higher-Income Beneficiaries” at SSA.gov/benefits/medicare/medicare-premiums.html.

Other Medicare Increases

In addition to the Part B and Part D premium increases, there are other cost increases you should take into consideration. For example, the annual deductible for Medicare Part B will be $257 in 2025, which is $17 more than the 2024 deductible of $240. In addition, the deductible for Medicare Part A, which covers hospital services, will increase to $1,676 in 2025. This amount is $44 more than the 2024 deductible of $1,632. There are no surcharges on Medicare deductibles for high earners. For more information on all the Medicare costs for 2025 visit Medicare.gov/basics/costs or call 800-633-4227.
