Medicare premiums are deducted directly from your Social Security payment each month

When you turn 65 and enroll in Medicare, the program takes money from your Social Security check to pay for Part B (medical insurance) and Part D (prescription drug coverage) if you have them. Part A (hospital insurance) is usually free. The amount varies by person because premiums depend on your income and when you enrolled. Most people see the deduction appear automatically on their Social Security statement — you do not receive a separate bill.

The deduction happens through a process called "premium billing." Social Security calculates what you owe Medicare, subtracts it from your monthly benefit, and sends the remainder to you. If your Social Security payment is too small to cover the full premium, you may owe the difference directly to Medicare.

Key Takeaways

  • Part B premiums in 2024 range from $174.70 to $609.00 per month depending on your income, and this amount is deducted from your Social Security check.
  • Part D premiums vary by plan and insurance company, typically ranging from $7 to $100 per month, and are also deducted from Social Security if you enroll.
  • If your income is higher than a certain threshold, you pay an additional surcharge called Income-Related Monthly Adjustment Amount (IRMAA) on top of the standard premium.
  • You can see exactly what Medicare is deducting by checking your Social Security statement online or calling Social Security directly.
  • If you do not enroll in Part B when you first become may be able to access, you may face a permanent penalty that increases your premiums for life.

Part B premiums and how they are deducted

Part B covers doctor visits, outpatient care, and medical equipment. The standard Part B premium for 2024 is $174.70 per month for most people, but this amount changes each year. Social Security deducts this directly from your benefit before you receive your payment.

However, if your income from the previous two years exceeds certain thresholds, you pay more. For 2024, if you filed taxes as a single person and your modified adjusted gross income was over $97,000, Medicare charges you an extra amount called an Income-Related Monthly Adjustment Amount (IRMAA). For married couples filing jointly, the threshold is $194,000. The higher your income, the more you pay — premiums can reach $609.00 per month at the highest income level.

Social Security uses your tax return from two years prior to calculate IRMAA. If your income drops significantly — such as after retirement, a spouse's death, or a major life change — you can request a reduction in your IRMAA by contacting Social Security and providing documentation of the change.

Part D prescription drug coverage deductions

Part D is optional coverage for prescription medications. Unlike Part B, there is no single standard premium — each insurance company sets its own price for each drug plan. Premiums typically range from $7 to $100 per month, though some plans cost more. You choose which plan to enroll in during your initial enrollment period or during the annual open enrollment period in October through December.

If you do not enroll in Part D when you first become may be able to access and later decide you want it, you may face a permanent late enrollment penalty. This penalty is added to your premium for as long as you have Part D coverage. The penalty is calculated based on how many months you went without coverage.

Like Part B, Part D premiums are deducted from your Social Security check if you enroll. The deduction appears on your Social Security statement each month.

What happens if your Social Security payment is too small

If your monthly Social Security benefit is less than the total amount Medicare needs to deduct for Part B and Part D premiums, Social Security will deduct as much as possible from your check. You then owe Medicare the remaining balance directly.

Medicare will send you a bill for the unpaid portion, usually monthly. If you do not pay, Medicare can withhold future Social Security payments or take other collection actions. If you are having trouble paying, contact Medicare directly at 1-800-MEDICARE to discuss payment plans or other options.

How to check what is being deducted

You can see your Medicare deductions on your Social Security statement. Create an account at ssa.gov, log in, and view your statement under "Benefit Verification." The statement shows your gross benefit amount and lists all deductions, including Medicare Part B and Part D premiums.

You can also call Social Security at 1-800-772-1213 to ask about your deductions. Have your Social Security number ready. If you believe the deduction is wrong, ask Social Security to review your account and explain the amount.

To see details about your specific Medicare premiums and IRMAA, log into your Medicare account at Medicare.gov or call 1-800-MEDICARE. Both Social Security and Medicare can explain why your deduction is the amount it is.

Changes to deductions and when they take effect

Medicare premiums change each year, usually in January. Social Security automatically adjusts your deduction to reflect the new premium. You will see the change on your January statement.

If your income changes significantly during the year — such as after you retire, receive a large inheritance, or experience a major life event — your IRMAA may change. You can request a review by contacting Social Security and providing proof of the change. If Social Security approves your request, your deduction will be adjusted going forward.

If you enroll in or drop Part D coverage, the deduction changes the month your coverage begins or ends. Make sure you understand the timing before you make changes, because late enrollment penalties can be costly.

Frequently Asked Questions

Can I refuse to have Medicare deducted from my Social Security?

No. If you are enrolled in Medicare Part B or Part D, the premiums must be deducted from your Social Security payment. This is automatic and required by law. You cannot opt out of the deduction, though you can drop Part D coverage if you choose.

What if I think my IRMAA is calculated wrong?

Contact Social Security and request a review. Bring documentation of your actual income for the year Medicare used to calculate your IRMAA (two years prior). If your income has dropped since then due to retirement or a major life change, Social Security may reduce your IRMAA.

Do I have to enroll in Part D, or can I skip it?

Part D is optional, but if you do not enroll when you first become may be able to access and later want it, you will pay a permanent late enrollment penalty. If you have other prescription drug coverage through an employer or union, you may be able to delay Part D without penalty — check with your plan.

Why is my Part B premium higher than my friend's?

Your premium depends on your income from two years ago. If your income was higher than your friend's, you pay IRMAA on top of the standard premium. Income thresholds and surcharge amounts change each year, so your premium may differ even if your current income is similar.

What if I go back to work and my income increases?

Your IRMAA is based on your tax return from two years prior, so an increase in current income will not affect your premium until two years later. However, if you expect your income to drop in the future, you can request a review early by contacting Social Security.
