You stop paying Medicare taxes when you reach age 65 and enroll in Medicare Part A, or when you retire — whichever comes first

Medicare taxes (the 1.45% withheld from your paycheck, plus the employer match) stop being deducted once you are no longer working. If you keep working past 65, the tax continues until you actually retire. The key is employment status, not age alone. Self-employed people pay a different calculation but follow the same rule: the tax stops when self-employment income stops.

There is one exception: if you earn over a certain threshold, an additional 0.9% Medicare tax applies to wages above that amount. This extra tax does not stop at 65 and does not stop when you retire — it continues as long as you have wage income above the threshold, regardless of age. The threshold is $200,000 for single filers and $250,000 for married couples filing jointly, and it is based on your individual income, not household income.

Key Takeaways

  • Standard Medicare tax (1.45%) stops when you leave the workforce, whether that happens at 65 or earlier or later.
  • If you work past 65, Medicare taxes continue to be withheld from your paycheck until you retire.
  • The additional 0.9% Medicare tax on high earners continues indefinitely if your wages stay above the threshold, even after you turn 65 or retire.
  • Self-employed people pay both the employee and employer portions (2.9% total) and stop when they stop earning self-employment income.
  • You cannot opt out of Medicare taxes while you are working — they are mandatory for all wage earners and self-employed individuals.

How Medicare tax works while you are still employed

Your employer withholds 1.45% of your gross wages for Medicare tax. Your employer also pays a matching 1.45%, for a total of 2.9% going into the Medicare system. This happens automatically with every paycheck, starting from your first dollar of income — there is no threshold you have to reach before the tax kicks in.

If you are self-employed, you pay both portions yourself: 2.9% of your net self-employment income. You calculate this on your tax return (Schedule SE) and pay it when you file or through quarterly estimated tax payments. The self-employed rate is higher because you are covering both the employee and employer share.

What happens when you retire before 65

If you retire at 62 or any age before 65, Medicare taxes stop the moment your employment ends. You will no longer receive a W-2 or 1099 from that job, and no Medicare tax will be withheld. However, you will not be enrolled in Medicare automatically — you have to enroll yourself during your initial enrollment period, which begins three months before the month you turn 65.

If you retire early and have no other income, you have no Medicare tax to pay. If you have investment income, rental income, or other non-wage income, those sources do not trigger Medicare tax. Only wages and self-employment income are subject to Medicare tax.

What happens if you keep working past 65

Reaching 65 does not stop Medicare taxes. If you are still employed and earning wages, the 1.45% tax continues to be withheld. You can enroll in Medicare at 65 even while working, but enrollment does not affect your tax withholding — the tax continues as long as you have an employer taking it out.

Many people work into their late 60s or 70s. Medicare taxes keep coming out the entire time. The tax stops only when you leave that job or retire from self-employment. Some people have multiple jobs; if you leave one job but keep another, taxes stop on the job you left and continue on the job you keep.

The additional 0.9% tax for high earners

If your wages exceed $200,000 (single) or $250,000 (married filing jointly), an additional 0.9% Medicare tax applies to the amount over the threshold. This tax has no age limit and does not stop at retirement. It continues as long as you have wage income above the threshold.

This extra tax is withheld by your employer if you cross the threshold during the year. If you have multiple employers and your combined wages exceed the threshold, you may need to adjust withholding or reconcile the tax on your return. Unlike the standard Medicare tax, this additional tax can result in a refund or a balance due when you file.

How to confirm Medicare taxes have stopped

Check your pay stub. If no line item shows Medicare tax being withheld, the tax has stopped. Your employer should also provide a W-2 at the end of the year showing total Medicare tax paid during that year — if you retired mid-year, the W-2 will reflect tax only through your last paycheck.

If you are self-employed and no longer have self-employment income, you will not owe Medicare tax on your return. If you have questions about whether a particular income source is subject to Medicare tax, the IRS website or a tax professional can clarify.

What Medicare taxes paid for

The Medicare taxes you paid throughout your working life funded the Medicare program. Part A (hospital insurance) is funded primarily by Medicare tax. Part B (medical insurance) and Part D (prescription drug coverage) are funded partly by general tax revenue and partly by premiums you pay as a beneficiary.

Once you are enrolled in Medicare, you pay premiums for coverage, but you do not pay the 1.45% Medicare tax anymore (unless you are still working). The premiums are separate from the payroll tax and are deducted from your Social Security check or paid directly to Medicare, depending on how you set it up.

Frequently Asked Questions

Can I opt out of Medicare taxes while I am working?

No. Medicare tax is mandatory for all employees and self-employed people. There is no religious exemption, no hardship exemption, and no way to avoid it while you have wage or self-employment income. It is a federal requirement.

If I work part-time after I retire, do I have to pay Medicare taxes again?

Yes. If you take a part-time job or return to work in any capacity, Medicare tax resumes on that income. The 1.45% (or 2.9% if self-employed) is withheld or paid just as it was before you retired. The additional 0.9% tax also applies if your income exceeds the threshold.

Do I have to enroll in Medicare when I turn 65 if I am still working?

If your employer has 20 or more employees, you can delay Medicare enrollment without penalty. If your employer has fewer than 20 employees, you should enroll at 65 to avoid penalties later. Check with your employer's HR department about the company size and your enrollment options.

What if I worked in multiple states — do I owe Medicare tax in each one?

Medicare tax is federal, not state-based. You owe it on all wages regardless of which state you worked in. Your employer withholds it the same way everywhere. State income tax is separate and varies by state.

Does Medicare tax come out of my Social Security check?

No. Social Security and Medicare are separate programs. Once you start receiving Social Security, no Medicare tax is withheld from those payments. Medicare premiums may be deducted from your Social Security check, but that is different from Medicare tax.
