Your Guide to Medicare Part B Premiums and Deductions in 2025
Navigating the costs associated with Medicare can be complex. A common question retirees and those approaching age 65 ask is, "How much is taken out of Medicare for Part B?" While there's a standard premium, the actual amount can vary significantly based on your income and how you receive your benefits. This comprehensive guide will walk you through the standard costs for 2025, explain the factors that could make you pay more, and detail how these payments are typically handled.
The 2025 Standard Medicare Part B Premium
For the year 2025, the standard monthly premium for Medicare Part B is $174.70. This is the amount that the vast majority of beneficiaries pay. This premium covers a wide range of outpatient services and medical supplies, including:
- Doctor visits
- Ambulance services
- Durable medical equipment (DME)
- Mental health services
- Preventive care
This standard premium can be adjusted annually. The Centers for Medicare & Medicaid Services (CMS) typically announces the next year's premium in the fall. For most people, this is the foundational cost of their Part B coverage.
How Is the Part B Premium Paid?
The method of payment for your Part B premium depends on whether you're receiving certain federal benefits.
- Deduction from Social Security: If you are receiving benefits from Social Security, the Railroad Retirement Board (RRB), or the Office of Personnel Management (OPM), your Part B premium will be automatically deducted from your monthly benefit payment. This is the most common method and requires no action on your part. You'll see this deduction listed on your benefit statement.
- Medicare Premium Bill: If you are not yet receiving the benefits listed above, you will receive a quarterly bill from Medicare called Form CMS-500, "Notice of Medicare Premium Payment Due." You will need to pay this premium directly to Medicare. You can pay online, through your bank's bill pay service, by mail, or by signing up for Medicare Easy Pay, a free service that automatically deducts your premium from a checking or savings account each month.
Understanding the Income-Related Monthly Adjustment Amount (IRMAA)
While the standard premium is $174.70, some beneficiaries are required to pay more. This higher premium is due to the Income-Related Monthly Adjustment Amount, or IRMAA. IRMAA is an extra charge added to your Part B (and Part D) premium if your modified adjusted gross income (MAGI) as reported on your IRS tax return from two years ago is above a certain threshold.
For 2025, the Social Security Administration uses your tax return from 2023 to determine if you owe an IRMAA. The income thresholds are different for those who file taxes individually versus jointly.
Here are the key aspects of IRMAA:
- It is not a penalty, but rather a requirement for higher earners to contribute more to their healthcare coverage.
- The income brackets are adjusted each year for inflation.
- If your income has decreased significantly due to a life-changing event (such as marriage, divorce, or retirement), you can request a new determination from the Social Security Administration.

| 2023 Individual Tax Return | 2023 Joint Tax Return | 2025 IRMAA Amount | 2025 Total Monthly Part B Premium |
|---|---|---|---|
| ≤ $103,000 | ≤ $206,000 | $0.00 | $174.70 |
| > $103,000 and ≤ $129,000 | > $206,000 and ≤ $258,000 | $69.90 | $244.60 |
| > $129,000 and ≤ $161,000 | > $258,000 and ≤ $322,000 | $174.70 | $349.40 |
| > $161,000 and ≤ $193,000 | > $322,000 and ≤ $386,000 | $279.50 | $454.20 |
| > $193,000 and < $500,000 | > $386,000 and < $750,000 | $384.30 | $559.00 |
| ≥ $500,000 | ≥ $750,000 | $419.30 | $594.00 |
Don't Forget the Part B Deductible and Coinsurance
Beyond your monthly premium, there are other out-of-pocket costs associated with Part B.
- Annual Deductible: In 2025, you must pay an annual deductible of $240 before Medicare starts to pay its share. You are responsible for 100% of your Medicare-approved costs for most services until you meet this deductible.
- Coinsurance: After your deductible is met, you typically pay 20% of the Medicare-approved amount for most covered services. There is no annual cap on this 20% coinsurance, which can lead to significant out-of-pocket expenses for those with serious health issues. This is a primary reason many beneficiaries choose to enroll in a Medicare Supplement (Medigap) plan or a Medicare Advantage plan.
How to Potentially Lower Your Medicare Costs
If you have limited income and resources, you may qualify for programs that can help pay your Medicare premiums and other costs.
- Medicare Savings Programs (MSPs): These state-run programs help pay for Part A and/or Part B premiums, deductibles, coinsurance, and copayments. There are four kinds of MSPs, including the Qualified Medicare Beneficiary (QMB) program.
- Medicaid: In some cases, you may qualify for full Medicaid benefits, which can work with Medicare to cover a wide range of health costs.
- Medicare Advantage (Part C) Plans: These plans are offered by private insurance companies approved by Medicare. They must cover everything Original Medicare covers, but often have different cost structures, including lower out-of-pocket costs and an annual maximum out-of-pocket limit. However, they may have network restrictions.

Conclusion: Planning is Key
Understanding how much is taken out of Medicare for Part B is a critical part of retirement financial planning. For 2025, most will pay the standard $174.70 premium, likely deducted directly from Social Security. However, you must be aware of the IRMAA thresholds and the Part B deductible and coinsurance. By reviewing your income, understanding the costs, and exploring potential assistance programs or alternative coverage like Medicare Advantage, you can budget effectively and ensure you have the healthcare coverage you need without any financial surprises.
