FICA Tax (an acronym for the Federal Insurance Contributions Act tax) is a mandatory U.S. federal payroll tax. Think of it as a forced savings plan managed by the federal government. This tax is automatically deducted from the paychecks of most employees and is also paid by employers on their employees' behalf. If you're self-employed, you'll pay a similar tax. The money collected doesn't just vanish into a government black hole; it's specifically earmarked to fund two of America's largest social insurance programs: Social Security, which provides retirement, disability, and survivor benefits, and Medicare, which provides hospital insurance for the elderly and disabled. Understanding FICA is the first step in figuring out your true take-home pay—the actual cash you have available to save and invest.
The FICA tax isn't a single flat rate; it's a combination of two separate taxes. For employees in 2024, the total rate is 7.65% on their gross wages. This is how it splits:
Let's look at each piece more closely.
The 6.2% Social Security tax is designed to fund retirement and disability benefits. However, there's a crucial catch: it only applies up to a certain annual income level. This ceiling is known as the Social Security wage base limit. The Internal Revenue Service (IRS) adjusts this limit almost every year to account for inflation. For example, in 2024, you only pay Social Security tax on the first $168,600 you earn. Any income above that amount is not subject to this specific tax. This is a significant detail for high earners, as it effectively lowers their overall tax rate on income past the limit.
The 1.45% Medicare tax funds the hospital insurance program for seniors. Unlike the Social Security tax, there is no income limit for Medicare. You pay the 1.45% tax on every single dollar you earn. Furthermore, high-income earners are subject to an Additional Medicare Tax. If your income exceeds a certain threshold (e.g., $200,000 for single filers), you must pay an extra 0.9% in Medicare tax on the income above that threshold. This additional tax is paid only by the employee, not the employer.
It's not just the employee footing the bill. FICA is a shared responsibility.
For every dollar an employee pays in FICA tax, their employer pays a matching amount.
So, the total FICA contribution to the government is a hefty 15.3% of an employee's wages. As an investor analyzing a company, remember this hidden cost! A company's true expense for an employee is significantly more than just their salary.
If you work for yourself—as a freelancer, consultant, or small business owner—you are considered both the employee and the employer. Therefore, you are responsible for paying the full shebang. This is officially known as the Self-Employment Contributions Act (SECA) tax, which combines the employee and employer portions. The SECA tax rate is 15.3% on your net earnings from self-employment (12.4% for Social Security up to the annual limit, plus 2.9% for Medicare on all earnings). However, there's a silver lining: you can deduct the “employer” half of your SECA tax (7.65%) when calculating your Adjusted Gross Income (AGI). This is a valuable deduction that lowers your overall income tax liability.
While FICA is a tax, not an investment, a savvy value investor understands all the forces affecting their financial life.
