What gets taken out of Social Security for Medicare

Medicare premiums are deducted directly from your Social Security payment each month. The amount depends on which parts of Medicare you have enrolled in and your income level. For 2024, the standard Part B premium (doctor and outpatient care) is $164.90 per month, though some people pay more based on their yearly income. Part D premiums (prescription drug coverage) vary by plan and can range from roughly $7 to $100 per month. If you have Part A (hospital coverage), there is typically no premium if you or your spouse paid Medicare taxes for at least 10 years.

The deduction happens automatically once you turn 65 and enroll in Medicare. Social Security sends the payment to Medicare, and the remainder goes to your bank account. You do not receive a separate bill for Part B or Part D — the money straightforward does not appear in your deposit. If you have a Medigap or Medicare Advantage plan, those premiums are usually paid separately to the insurance company, not taken from Social Security.

Key Takeaways

  • Part B premiums are deducted from your Social Security check automatically, with the standard 2024 amount at $164.90 per month, though higher earners pay more.
  • Part D prescription drug premiums vary by plan and are also taken from Social Security, ranging from roughly $7 to $100 monthly depending on your coverage choice.
  • Part A has no premium for most people, but Part B and Part D deductions reduce the amount of Social Security you actually receive in your bank account.
  • If your Social Security payment is smaller than your Medicare premiums, you will receive a bill from Medicare for the difference.

Income-based premium increases for Part B and Part D

If your income is above a certain threshold, you pay a higher Part B premium — sometimes significantly higher. Medicare uses your income from two years prior to set the rate. For 2024, if you filed taxes individually and your income was over $97,000, you enter an income-related adjustment amount (IRAA) bracket. Married couples filing jointly pay more if their combined income exceeds $194,000. The brackets go up in steps, and the highest earners can pay three to four times the standard premium.

Part D has similar income-based increases. If you fall into a higher bracket, your prescription drug premium rises. You receive a notice in the mail showing your income-related premium amount and the bracket you fall into. You can appeal the amount if your income dropped due to retirement, job loss, or death of a spouse — Medicare will recalculate using your current year income instead.

When your Social Security payment is less than your premiums

If your Social Security benefit is smaller than your combined Part B and Part D premiums, Medicare cannot take more than your full payment. Instead, you receive a bill from Medicare for the amount owed. This happens most often to people who claim Social Security before their full retirement age and also enroll in Medicare at 65. Your Social Security payment goes to Medicare, and you owe the remainder out of pocket.

You can pay this bill by mail, phone, or online through the Medicare website. If you do not pay, your Part B coverage can be terminated, though Part D and Part A are not affected in the same way. Contact Medicare directly if you cannot pay the full amount — they can discuss payment plans or connect you with resources.

How to see what Medicare is taking from your check

Your Social Security statement shows the gross amount before Medicare deductions. To see the actual deduction, log into your Social Security account at ssa.gov or call 1-800-772-1213 and ask for a detailed payment breakdown. You can also view your Medicare premiums by logging into Medicare.gov and selecting "My Medicare" or by calling 1-800-MEDICARE (1-800-633-4227).

Your bank deposit will show the net amount — what remains after Medicare takes its share. If the deduction seems wrong, contact Social Security first to confirm the amount they sent to Medicare, then contact Medicare if there is a discrepancy. Both agencies can take several weeks to investigate, so keep records of your statements while they look into it.

Changes to your premiums and when they take effect

Medicare premiums change each year, usually announced in September for the following January. If your premium increases, the change takes effect on January 1. However, there is a rule called the hold-harmless provision that protects most people: your Social Security payment cannot decrease because of a Medicare premium increase. If your premium goes up more than your Social Security cost-of-living adjustment (COLA), Social Security absorbs the difference and your take-home payment stays the same or increases slightly.

This protection does not explore if you are new to Medicare, if you have higher income-related premiums, or if you are not yet receiving Social Security. If any of these explore to you, a premium increase will reduce your net payment. You will receive a notice in the mail before the change takes effect, showing your new premium amount and effective date.

What happens if you delay Social Security but enroll in Medicare at 65

You can enroll in Medicare at 65 even if you have not yet claimed Social Security. If you do, you will receive a separate bill from Medicare for Part B and Part D premiums instead of having them deducted from Social Security. This bill arrives monthly or quarterly, depending on how you set it up. You pay it directly to Medicare until you claim Social Security, at which point the deductions switch to your Social Security payment.

Some people choose this route to delay Social Security and receive a larger benefit later while still getting Medicare coverage at 65. The trade-off is paying Medicare premiums out of pocket for those years. Once your Social Security starts, the premiums move to automatic deduction and your net Social Security payment reflects the reduction.

Frequently Asked Questions

Can I opt out of Part B to keep more of my Social Security?

You can decline Part B when you first turn 65, but you will face a permanent penalty if you enroll later — your premium increases 10 percent for each year you delayed. The exception is if you are still working and covered by your employer's health plan. Once you leave that job, you have a limited window to enroll without penalty.

What if I think my income-related premium is wrong?

You can appeal the amount within 60 days of receiving the notice. Contact Social Security or Medicare and explain why your income is lower now — job loss, retirement, or death of a spouse are common reasons. They will recalculate using your current year income and adjust your premium if warranted.

Do Medigap or Medicare Advantage premiums come out of Social Security too?

No. Medigap and Medicare Advantage premiums are paid separately to the insurance company, usually by automatic bank withdrawal or check. Only Part B and Part D premiums are deducted from Social Security. You manage Medigap and Advantage payments on your own.

Will my Medicare premium increase if I get a raise or inheritance?

Medicare uses your income from two years prior, so a raise or inheritance in the current year will not affect your premium until two years later. If you receive a large one-time payment like an inheritance, it may push you into a higher bracket the following year. You can appeal if the increase is based on income you no longer have.

What if I move to another country — do Medicare premiums still come out?

If you continue to receive Social Security while living abroad, Part B and Part D premiums are still deducted. However, your coverage may be limited outside the United States. Contact Medicare before you move to understand what services are covered where you are going.
