How Do You Figure Out FICA: A Complete Guide to Understanding Social Security and Medicare Taxes
FICA taxes are one of the most important yet often misunderstood aspects of employment income. Understanding how to calculate FICA taxes is crucial for both employees and employers, as these contributions directly impact take-home pay and retirement benefits.

Step-by-Step Process for Calculating FICA Taxes
Step 1: Determine Your Total Taxable Wages

- Regular salary or hourly wages
- Bonuses and overtime pay
- Commission income
- Severance pay
- Certain fringe benefits

Step 2: Apply the Social Security Tax Rate

Most guides skip this. Don't.
Here's one way to look at it: if you earn $85,000 annually: $85,000 × 0.062 = $5,270 Social Security tax
Step 3: Calculate Medicare Tax
Multiply your total taxable wages by 1.45% to determine the base Medicare tax. Here's the thing — if your income exceeds the applicable threshold, calculate the additional 0. 9% Medicare tax on the excess amount.
Using the same $85,000 salary: $85,000 × 0.0145 = $1,232.50 Medicare tax
Step 4: Add Both Components Together
Combine the Social Security and Medicare tax amounts to get your total FICA contribution:
$5,270 + $1,232.50 = $6,502.50 total FICA tax
Your employer would contribute an equal amount, making the total FICA cost for your employment $13,005.
Special Considerations and Common Scenarios
Multiple Jobs and Wage Base Limits
When working multiple jobs, each employer calculates FICA taxes independently without knowledge of your other employment. This can result in paying Social Security tax on income exceeding the annual wage base limit. The Social Security Administration tracks total earnings across all employers and refunds excess contributions when you file your tax return.
High-Income Earners and Additional Medicare Tax
High-income earners must carefully monitor their total compensation, as the additional Medicare tax applies based on combined income from all sources. This includes wages, self-employment income, interest, dividends, and other unearned income.
Self-Employment Tax Implications
Self-employed individuals pay the full FICA tax amount through the self-employment tax, which equals 12.4% for Social Security (on income up to the wage base limit) and 2.9% for Medicare, plus the additional 0.9% for high earners. That said, self-employed taxpayers can deduct the employer-equivalent portion of their self-employment tax when calculating adjusted gross income.
