What Is the Percentage of Medicare Tax? 2025 Rates Explained
Medicare Tax Rate for 2025: What You Need to Know
The Medicare tax rate for 2025 remains consistent for both employees and employers, emphasizing simplicity and predictability for both payroll and individual tax planning. In 2025, the standard Medicare tax rate is 1.45% for employees, and 1.45% for employers on all earned income. This means that, combined, an employee’s wages are subject to a total of 2.9% for Medicare tax every pay period. Notably, there is no wage base limit-Medicare tax applies to all wage amounts, setting it apart from the Social Security tax, which has an income cap.
These contributions are a key component of FICA (Federal Insurance Contributions Act) taxes, which help fund Medicare benefits. Employees will find Medicare tax withholding listed separately on their pay stubs. Employers are responsible for matching the employee’s Medicare tax contribution, ensuring compliance with federal payroll regulations.
2025 Standard Medicare Tax Rate Table
| Party | Rate |
|---|---|
| Employee | 1.45% |
| Employer | 1.45% |
| Total per Employee | 2.9% |
This focus on a no wage cap Medicare tax is an important distinction that impacts both high and moderate earners. Additional details on how these rates compare with Social Security tax can be found in the section below.
How Medicare Tax Is Calculated
For employees, calculating your Medicare tax is straightforward. You multiply your gross wages-without any income cap-by the standard 1.45% Medicare tax rate. Employers must also perform this calculation for each employee and remit the same amount.
Example 1: If an employee earns $60,000 in 2025:
- Employee Medicare tax: $60,000 × 1.45% = $870
- Employer Medicare tax: $60,000 × 1.45% = $870
- Total Medicare tax: $870 + $870 = $1,740
If an employee’s wages exceed the additional Medicare tax threshold (see the next section), the extra 0.9% will apply to the income above the prescribed cutoff.
Self-employed individuals calculate Medicare tax by multiplying their net earnings from self-employment by the combined rate of 2.9%. Should your self-employment income exceed the additional Medicare tax threshold, the 0.9% surtax also applies, much like for employees. Accurate calculation and withholding help avoid surprises at tax time.
Payroll Tax Withholding and Reporting
- Employees: Medicare tax withheld is reported on Form W-2 (Box 6).
- Employers: Responsible for timely deposit and reporting via payroll tax forms, ensuring accurate matching for each employee.
- Self-Employed: Use Schedule SE (Form 1040) to calculate Medicare tax owed on net self-employment earnings.

Additional Medicare Tax for High Earners
The Additional Medicare Tax is designed to ensure that higher-income individuals contribute more toward Medicare funding. Starting in 2013 and continuing in 2025, this surtax imposes an extra 0.9% on wages, compensation, or self-employment income above certain thresholds. Importantly, only the employee (or self-employed individual) pays this additional tax-employers do not match it.
2025 Additional Medicare Tax Thresholds
| Filing Status | Income Threshold | Additional Medicare Tax Rate |
|---|---|---|
| Single | $200,000 | 0.9% |
| Married Filing Jointly | $250,000 | 0.9% |
| Married Filing Separately | $125,000 | 0.9% |
Example: Calculating Additional Medicare Tax
Scenario: A single filer earns $250,000:
- Standard Medicare tax (1.45%) is applied to the first $200,000:
- $200,000 × 1.45% = $2,900
- Additional Medicare tax (0.9%) applies to the remaining $50,000:
- $50,000 × 0.9% = $450
- Total Medicare tax owed: $2,900 + $450 = $3,350
The Additional Medicare Tax is withheld by employers only on wages over $200,000, regardless of the employee’s total household earned income. It is an employee-only tax. If cumulative wages from multiple employers surpass the threshold, any shortfall in withholding is reconciled on your federal tax return.

Medicare Tax vs. Social Security Tax: Key Differences
Though both taxes fall under the FICA umbrella, understanding their structural differences ensures compliance, especially for payroll professionals and self-employed individuals.
| Tax Type | Employee Rate | Employer Rate | Wage Base Limit (2025) | Additional Tax for High Earners |
|---|---|---|---|---|
| Medicare | 1.45% | 1.45% | None | 0.9% above threshold (employee only) |
| Social Security | 6.2% | 6.2% | $176,100 | None |
The Social Security tax is assessed on wages up to the annual wage base limit-in 2025, that is $176,100. Any earnings above this amount are not subject to additional Social Security tax for the year. However, Medicare tax applies to all earned income without a cap, and the 0.9% additional tax applies at higher earnings levels, reflecting Congress’s ongoing emphasis on expanding Medicare’s funding base.

Medicare Tax for Self-Employed Individuals
If you are self-employed, you pay both the employer and employee portions of Medicare tax through your annual tax return, rather than via payroll withholding. The Medicare tax rate for self-employed individuals in 2025 is 2.9% on net self-employment income. Should your earnings surpass the income thresholds discussed above, the 0.9% Additional Medicare Tax will also apply to the higher portion.
2025 Medicare Tax Calculation for the Self-Employed
- Calculate net earnings (gross income minus qualifying business expenses)
- Apply 2.9% to total net earnings for Medicare tax
- Add 0.9% on amounts above your filing threshold
Example: A self-employed, single filer earns $220,000 net in 2025.
- First $200,000 at 2.9%: $200,000 × 2.9% = $5,800
- Next $20,000 at 3.8%: $20,000 × (2.9% + 0.9%) = $760
- Total Medicare tax owed: $5,800 + $760 = $6,560
For self-employed taxpayers, accurate record-keeping ensures you claim all possible deductions, optimizing your net income and tax liability.

Frequently Asked Questions
Is there a wage cap for Medicare tax?
No. Unlike Social Security tax, Medicare tax is assessed on all earned income-there is no wage base limit for calculating Medicare tax obligations.
Who pays the Additional Medicare Tax?
Only employees (and self-employed individuals) pay the additional 0.9% on earnings above the threshold. Employers do not match the Additional Medicare Tax.
How is Medicare tax reported?
Medicare tax withholding for employees is listed on Form W-2 (Box 6). For self-employed individuals, it’s reported and calculated on Schedule SE, part of Form 1040. Proper documentation is key for compliance and potential audits.
Are bonuses and commissions subject to Medicare tax?
Yes. All taxable compensation-including bonuses, commissions, and overtime-is subject to the Medicare tax, without exception.
What if I have multiple jobs?
Each employer withholds Medicare tax on all your wages, with no coordination between them. If your combined earnings exceed the Additional Medicare Tax threshold, you may owe the extra 0.9% when you file your federal return. Staying proactive with estimated payments or withholdings can help avoid unexpected tax bills.
Does Medicare tax withholding automatically enroll me in Medicare?
No, paying Medicare tax does not mean you are automatically enrolled in Medicare. Eligibility for Medicare (such as Medicare Part B) is typically based on age or certain disabilities. Find out how and when you can enroll by reading How to Get Medicare.
How do changes in my supplement plan affect payroll tax?
Changing your Medicare Supplement Plan does not impact your Medicare tax withholding, as Supplement Plans relate to gap coverage-not tax liabilities. For guidance on switching plans, visit When Can I Change My Medicare Supplement Plan?.
