What Medicare Withholds From Your Wages

Medicare withholds 1.45% of your gross wages from every paycheck. Your employer matches that amount, contributing another 1.45%, for a combined total of 2.9%. If you are self-employed, you pay both portions yourself — 2.9% total — when you file your taxes.

This withholding is separate from Social Security tax (which is 6.2% from your pay, plus 6.2% from your employer). Together, Social Security and Medicare make up what you see labeled as "FICA" on your pay stub.

The withholding amount does not change based on your age, health status, or how much you have already paid in. It is a flat percentage that applies to all wages, with one exception: wages above a certain threshold face an additional Medicare tax.

Key Takeaways

  • Medicare withholds 1.45% from your paycheck, and your employer contributes a matching 1.45%.
  • If you earn over $200,000 as a single filer (or $250,000 married filing jointly), an additional 0.9% Medicare tax applies to income above that threshold.
  • Self-employed workers pay the full 2.9% Medicare tax themselves when they file their annual tax return.
  • The withholding rate has been the same since 1966 and does not vary by state or employer.

The Additional Medicare Tax for Higher Earners

If your income crosses a certain level, you owe an extra Medicare tax on top of the standard 1.45%. This additional Medicare tax is 0.9% and applies to wages above $200,000 for single filers, $250,000 for married couples filing jointly, and $125,000 for married couples filing separately.

Your employer is required to withhold this extra 0.9% once your year-to-date wages exceed the threshold. If you have more than one job, each employer withholds based only on what they pay you, so you might end up overpaying — but you can claim the overage back when you file your tax return.

This additional tax began in 2013 and applies to all wages, regardless of age or employment type.

How Withholding Appears on Your Pay Stub

On your pay stub, Medicare withholding usually appears as a line item labeled "Medicare Tax," "Med Tax," or "FICA Medicare." The amount shown is what your employer has removed from your gross pay for that pay period.

If you earn above the threshold for the additional Medicare tax, you may see a separate line for "Additional Medicare Tax" or "Medicare Surtax." This line only appears once your cumulative wages for the year cross the threshold.

Your employer's matching contribution does not appear on your pay stub — it is a cost to the employer that you do not see directly, but it is part of your total compensation.

Medicare Withholding for Self-Employed Workers

If you are self-employed, you do not have an employer to match your Medicare contribution. Instead, you pay the full 2.9% yourself when you file your annual tax return using Schedule SE (Self-Employment Tax).

You calculate your self-employment tax based on your net business income — not your gross revenue. This means you subtract business expenses before calculating what you owe. You can deduct half of your self-employment tax as a business expense on your tax return, which reduces your overall tax burden slightly.

If your net self-employment income exceeds $200,000 (single) or $250,000 (married filing jointly), you also owe the additional 0.9% Medicare tax on the amount above the threshold.

What Happens to Your Medicare Withholding

The money withheld from your paycheck goes directly to the Medicare Trust Fund, which pays for Part A (hospital insurance) and Part B (medical insurance) benefits. You do not have a separate account where your withholdings accumulate — the fund operates on a pay-as-you-go basis, meaning current workers' taxes pay for current beneficiaries' care.

Your Medicare withholding history is tracked by Social Security and becomes part of your earnings record. When you turn 65 and become may be able to access for Medicare, your may be able to access for premium-free Part A coverage depends partly on how many years you (or your spouse) paid Medicare tax.

You can view your lifetime Medicare withholding on your Social Security Statement, which you can access online at ssa.gov by creating a "my Social Security" account.

Withholding if You Are Retired or on Social Security

If you are already receiving Social Security benefits and continue to work, Medicare tax is still withheld from your wages at the standard 1.45% rate. This does not affect your Social Security benefit amount — it is a separate tax.

If you are on Medicare and have investment income, rental income, or other non-wage income, you do not pay Medicare tax on that income. Medicare tax applies only to wages and self-employment income.

Once you reach age 65 and enroll in Medicare, you stop paying the employee portion of Medicare tax (1.45%) on your wages. However, if you continue working past 65, your employer still withholds it unless you provide documentation that you are already on Medicare and no longer owe it — a situation that varies by employer policy.

Frequently Asked Questions

Why does my Medicare withholding vary from paycheck to paycheck?

Your withholding amount changes when your gross pay changes — for example, if you receive a bonus, work overtime, or take unpaid leave. The percentage (1.45%) stays the same, but the dollar amount depends on what you earned that pay period. If you cross the additional Medicare tax threshold partway through the year, you will see the extra 0.9% appear on later paychecks.

Can I reduce my Medicare withholding?

No. Medicare withholding is mandatory and does not change based on your personal circumstances, tax filing status, or number of dependents. It is a fixed percentage set by federal law.

What if I think my Medicare withholding is wrong?

Check your pay stub against your gross pay for that period. Multiply your gross pay by 1.45% (or 2.35% if you are over the threshold) — that should match the withholding shown. If it does not, contact your employer's payroll department. You can also review your lifetime earnings and withholding history on your Social Security Statement at ssa.gov.

Do I get Medicare withholding back if I do not use Medicare?

No. Medicare withholding is a tax, not a savings account. Even if you have private insurance or do not use Medicare services, the withholding goes to the Medicare Trust Fund and does not return to you.

Is Medicare withholding the same in every state?

Yes. Medicare withholding is a federal tax and is the same nationwide — 1.45% plus the additional 0.9% if applicable. State income tax, which is separate, varies by state.
