Quick Answer
The Medicare tax rate in 2026 is 1.45% for employees and 1.45% for employers (2.9% combined). Self-employed individuals pay the full 2.9% as part of self-employment tax. An Additional Medicare Tax of 0.9% applies to earnings exceeding $200,000 for single filers, $250,000 for married filing jointly, or $125,000 for married filing separately. Unlike Social Security tax, there is no income cap on Medicare tax. The Medicare tax funds Part A (hospital insurance), which covers inpatient hospital stays, skilled nursing, hospice, and some home health care.

Understanding Your Coverage Options
Standard Medicare Tax Rate (Employees and Employers)
The standard Medicare tax rate is 1.45% for employees and 1.45% for employers, totaling 2.9% of all wages. This tax is part of FICA (Federal Insurance Contributions Act) and is automatically withheld from your paycheck. Your employer pays the other 1.45% on your behalf - you never see this amount deducted from your pay.
Unlike Social Security tax, which has a wage base limit ($184,500 in 2026), the Medicare tax has no income cap. Every dollar you earn in wages, salaries, and tips is subject to the 1.45% Medicare tax, regardless of how much you make. This means someone earning $50,000 pays $725 in Medicare tax, while someone earning $500,000 pays $7,250 (before the Additional Medicare Tax kicks in).
The Medicare tax funds the Hospital Insurance (HI) Trust Fund, which pays for Medicare Part A benefits including inpatient hospital care, skilled nursing facility stays, hospice care, and some home health services. When you see 'MedFICA' or 'Medicare' on your pay stub, this is the 1.45% being withheld.
Medicare Tax vs. Social Security Tax
FICA consists of two taxes: Social Security (6.2% up to $184,500 in 2026) and Medicare (1.45% with no cap). Together they total 7.65% for employees. The key difference is that Social Security tax stops once you hit the wage base limit, but Medicare tax applies to all earned income with no ceiling.
Additional Medicare Tax (High-Income Earners)
Since 2013, an Additional Medicare Tax of 0.9% applies to earned income above certain thresholds. This brings the total Medicare tax rate to 2.35% (1.45% + 0.9%) on income above the threshold for employees. Employers do not match this additional tax - it is paid entirely by the employee.
The Additional Medicare Tax thresholds are: $200,000 for single filers and head of household, $250,000 for married filing jointly, and $125,000 for married filing separately. These thresholds are not indexed for inflation and have not changed since the tax was introduced in 2013. Your employer must begin withholding the additional 0.9% once your wages exceed $200,000 in a calendar year, regardless of your filing status.
If you are married filing jointly and your combined income exceeds $250,000, you may owe Additional Medicare Tax even if neither spouse individually earned over $200,000. In this case, you would calculate the tax owed on Form 8959 when filing your return and pay any difference. Conversely, if you are married filing jointly and your individual wages triggered withholding at $200,000 but your joint income is under $250,000, you can claim a credit for the over-withholding.
These Thresholds Are Not Indexed for Inflation
The Additional Medicare Tax thresholds ($200,000/$250,000/$125,000) have remained unchanged since 2013. As wages rise with inflation, more taxpayers are pulled into this bracket each year. There is currently no legislation to adjust these thresholds.
Self-Employment Medicare Tax
Self-employed individuals pay both the employee and employer portions of Medicare tax, totaling 2.9% of net self-employment income. This is part of the self-employment tax (15.3% total: 12.4% Social Security + 2.9% Medicare) reported on Schedule SE of your tax return.
The IRS allows you to deduct the employer-equivalent portion (1.45%) of your self-employment Medicare tax as a business expense on your Form 1040. This deduction reduces your adjusted gross income but does not reduce your self-employment tax itself. The calculation is applied to 92.35% of your net self-employment earnings (this adjustment accounts for the fact that employees do not pay FICA on the employer's share).
Self-employed individuals are also subject to the Additional Medicare Tax of 0.9% on self-employment income exceeding the same thresholds ($200,000 single / $250,000 joint / $125,000 married filing separately). This means a self-employed single filer earning $300,000 in net self-employment income would pay 2.9% on the full $300,000 plus an additional 0.9% on the $100,000 above the $200,000 threshold, for a total Medicare tax of $9,600.
How Medicare Tax Funds Your Benefits
The Medicare tax you pay during your working years funds Medicare Part A (Hospital Insurance). If you or your spouse paid Medicare taxes for at least 10 years (40 quarters), you qualify for premium-free Part A when you turn 65. This is why most people do not pay a monthly premium for Part A - they already paid for it through decades of Medicare tax contributions.
Medicare Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. The Part A Trust Fund collects all Medicare payroll tax revenue and uses it to pay these benefits. The fund is currently projected to be depleted by 2031, at which point it could only cover about 89% of scheduled benefits from incoming tax revenue.
It is important to understand that Medicare tax only funds Part A. Medicare Part B (outpatient/doctor visits) and Part D (prescription drugs) are funded separately through a combination of general tax revenues and monthly premiums paid by beneficiaries. If your income is high enough, you may also pay IRMAA surcharges on your Part B and Part D premiums - but that is a separate system from the Medicare payroll tax.
Medicare Tax vs. IRMAA: Two Different Systems
People often confuse the Medicare tax (a payroll tax on earned income) with IRMAA (Income-Related Monthly Adjustment Amount, a surcharge on Medicare premiums based on total income). These are two completely separate systems that affect you at different stages of life.
Medicare tax is paid during your working years on earned income (wages and self-employment income). It funds Part A and determines whether you qualify for premium-free Part A at age 65. IRMAA, on the other hand, is assessed after you enroll in Medicare and is based on your Modified Adjusted Gross Income (MAGI) from two years prior. IRMAA applies to all income sources including investments, pensions, and Social Security - not just earned income.
For 2026, the IRMAA threshold begins at $109,000 for single filers ($218,000 married filing jointly). If your income exceeds these levels, you pay higher monthly premiums for Part B and Part D. The highest IRMAA bracket (income above $500,000 single / $750,000 joint) adds $406.90 per month to your Part B premium alone. See our full IRMAA brackets guide for all 2026 thresholds and strategies to reduce your surcharge.
