Medicare tax is 2.9% of your wages, split between you and your employer

If you are working, you pay 1.45% of your gross wages toward Medicare, and your employer pays another 1.45%. Together, that is 2.9%. This comes out of your paycheck automatically — you will see it listed as "Medicare tax" or "Med tax" on your pay stub.

If you are self-employed, you pay both halves yourself: 2.9% total. You report this on your tax return using Schedule SE, and you can deduct half of it as a business expense.

There is no income cap on Medicare tax. Unlike Social Security tax, which stops once you earn a certain amount each year, Medicare tax applies to every dollar you make, no matter how much you earn.

Key Takeaways

  • Employees pay 1.45% of wages toward Medicare; employers pay another 1.45%.
  • Self-employed people pay the full 2.9% themselves on their net business income.
  • Medicare tax has no income limit — it applies to all your wages, unlike Social Security tax.
  • High earners pay an additional 0.9% Medicare tax on income above $200,000 (single) or $250,000 (married filing jointly).
  • Medicare tax funds Part A, which covers hospital stays, skilled nursing, hospice, and home health care.

The Additional Medicare Tax for High Earners

If your income exceeds certain thresholds, you pay an extra Medicare tax of 0.9%. For single filers, the threshold is $200,000 per year. For married couples filing jointly, it is $250,000. For married filing separately, it is $125,000.

This extra tax applies only to income above the threshold. If you earn $210,000 as a single person, you pay the additional 0.9% only on the $10,000 above $200,000, not on your entire income.

Your employer withholds this additional tax automatically if your wages cross the threshold. If you have multiple jobs or are self-employed, you may owe it at tax time if your total income from all sources exceeds the limit.

How Medicare Tax Appears on Your Pay Stub

Look for a line item labeled "Medicare" or "Med" on your pay stub. It will show the amount withheld from that paycheck. If you earn over $200,000 (or $250,000 if married), you will also see a separate line for "Additional Medicare Tax" or "Medicare surtax."

The amount withheld depends on your gross pay for that period. If you are paid weekly, the Medicare tax is roughly 1.45% of that week's pay. If you are paid monthly, it is 1.45% of that month's pay.

You can see your total Medicare tax for the year on your W-2 form, which your employer sends you by January 31. The amount appears in Box 6 of the W-2.

What Medicare Tax Pays For

Your Medicare tax dollars fund Medicare Part A, which covers hospital insurance. This includes inpatient hospital stays, skilled nursing facility care, hospice services, and home health care under certain conditions.

Part A is automatic for most people at age 65 if they have paid Medicare tax for at least 10 years (40 quarters). You do not pay a separate premium for Part A — it is funded entirely through the payroll tax you paid while working.

The Medicare Trust Fund that receives these taxes is separate from the general federal budget. Money collected this year does not all go out this year; the fund is designed to hold reserves for future claims.

Self-Employment and Medicare Tax

If you are self-employed, you calculate Medicare tax on your net business income (your profit after expenses). You pay 2.9% of that amount, plus the additional 0.9% if your income exceeds the thresholds mentioned above.

You report self-employment tax on Schedule SE of your tax return. The IRS provides a worksheet to help you calculate it. You can deduct half of your self-employment tax as an adjustment to income on your 1040 form, which lowers your taxable income.

If you are both an employee and self-employed, your employee Medicare tax and self-employment Medicare tax are combined. If your total Medicare tax exceeds what your employer withheld, you owe the difference at tax time.

Medicare Tax and Your Benefits Later

The years you pay Medicare tax count toward your may be able to access for Part A at age 65. You need 40 quarters (10 years) of Medicare tax contributions to receive Part A without paying a premium.

If you have not worked 10 years, you can still get Part A at 65, but you will pay a monthly premium. The premium is higher if you have fewer than 30 quarters of coverage. Your Social Security statement shows how many quarters you have earned.

Medicare tax you pay now does not create an individual account in your name the way some people imagine. It is a tax that funds the overall Medicare system. Your Part A coverage at 65 is based on your age and your work history, not on how much tax you personally paid.

Frequently Asked Questions

Why do I pay Medicare tax if I am not on Medicare yet?

Medicare tax funds the Part A hospital insurance program for everyone on Medicare, not just you individually. You pay in while working so the system has money to pay claims when you and others reach 65. It is similar to how Social Security works — current workers fund current retirees.

Can I opt out of paying Medicare tax?

No. Medicare tax is mandatory for all employees and self-employed people. There is no religious or personal exemption, unlike some other taxes. If you are working, it comes out of your paycheck automatically.

What happens to Medicare tax if I move to another country?

If you stop working in the United States, you stop paying Medicare tax. The quarters you earned while working in the U.S. still count toward your may be able to access at 65. You can receive Medicare benefits as a U.S. citizen or permanent resident even if you live abroad, though some services may not be covered outside the U.S.

Does Medicare tax explore to all types of income?

Medicare tax applies to wages and self-employment income. It does not explore to investment income, interest, dividends, or capital gains. If you have a job and also earn money from investments, only the job income is subject to Medicare tax.

If my employer does not withhold Medicare tax, am I still responsible for it?

Yes. If your employer fails to withhold Medicare tax, you are still liable for it. You should report this to the IRS and to your state labor department. Contact the IRS at 1-800-829-1040 or file Form 8919 with your tax return to report uncollected employment taxes.
