Key takeaways

• FICA stands for the Federal Insurance Contributions Act, and it funds Social Security and Medicare through a combined 7.65% tax on both employees and employers.
• For 2026, Social Security tax applies to wages up to $184,500, with a maximum employee contribution of $11,439. Medicare tax has no wage cap and includes an additional 0.9% surcharge for high earners.
• Self-employed individuals pay both the employee and employer portions of FICA, totaling 15.3%, but can deduct the employer-equivalent half when filing taxes.
• Accurate FICA withholding and timely deposits are essential for small businesses. Errors or missed payments can result in IRS penalties, so using payroll software helps you stay compliant.

If you run payroll, you've likely noticed deductions labeled Social Security and Medicare on every pay stub. These deductions come from a federal law that affects every employer and employee in the United States.

What does FICA stand for?

FICA stands for the Federal Insurance Contributions Act. Signed into law in 1935, FICA established a payroll tax that funds two major federal programs: Social Security and Medicare. Every time you pay an employee, you're required to withhold FICA taxes from their wages and contribute a matching amount as the employer.

The FICA tax rate breaks down into three categories:

• Employees pay 7.65% of their gross wages (6.2% for Social Security and 1.45% for Medicare)
• Employers match that 7.65%, bringing the combined contribution to 15.3% of each employee's pay
• Self-employed individuals pay the full 15.3% themselves, covering both sides of the contribution

You can find more details on FICA obligations in the IRS Topic No. 751 on Social Security and Medicare withholding rates.

Understanding how FICA shows up on paychecks helps you verify that withholdings are correct and that your employees see exactly where their money goes.

How FICA appears on an employee's pay stub

On a typical pay stub, FICA doesn't appear as a single line item. Instead, you'll see two separate deductions: one for Social Security and one for Medicare. Here's what those deductions look like for an employee earning $1,000 in gross pay:

• Social Security tax: $1,000 x 6.2% = $62.00
• Medicare tax: $1,000 x 1.45% = $14.50
• Total FICA withheld from the employee: $76.50
• Net pay after FICA (before other deductions): $923.50

The employer's matching 7.65% contribution does not appear on the employee's pay stub. That amount is a separate business expense you pay directly to the IRS.

Keep in mind that FICA withholdings are mandatory and aren't affected by the employee's W-4 form selections. The W-4 only determines federal income tax withholding. FICA deductions are calculated the same way for every employee, based solely on gross wages.

Knowing how to calculate FICA taxes from scratch gives you more control over your payroll process and helps you catch errors before they become problems.

How to calculate FICA taxes

Calculating FICA taxes involves a few straightforward steps. Whether you're running payroll manually or double-checking your software, this process helps you confirm the correct amounts for each pay period.

Step 1: Identify FICA-eligible compensation

FICA taxes apply to most forms of employee compensation. This includes:

• Regular wages and salaries
• Bonuses and commissions
• Tips reported by employees
• Overtime pay
• Certain fringe benefits

Step 2: Check the Social Security wage base limit

For 2026, Social Security tax only applies to the first $184,500 of an employee's wages. Once an employee's year-to-date earnings exceed that threshold, you stop withholding Social Security tax for the rest of the year. Medicare tax, however, has no wage cap and applies to all earnings.

Step 3: Calculate employee and employer amounts

Apply the FICA rates to the employee's gross pay for the period:

1. Multiply gross pay by 6.2% to get the Social Security withholding (up to the wage base limit)
2. Multiply gross pay by 1.45% to get the Medicare withholding
3. Add both amounts together for the total employee FICA withholding
4. As the employer, contribute the same combined amount

FICA tax calculation example

Here's how FICA works for an employee earning a $75,000 annual salary. Since $75,000 is below the $184,500 Social Security wage base, the full salary is subject to both taxes:

• Social Security (employee): $75,000 x 6.2% = $4,650
• Medicare (employee): $75,000 x 1.45% = $1,087.50
• Total employee FICA: $5,737.50
• Total employer FICA (matching): $5,737.50
• Combined FICA cost: $11,475

Beyond knowing the calculation, it helps to understand the specific rates and thresholds that determine how much you and your employees owe each year.

FICA rates and wage caps

FICA tax rates stay consistent for employees and employers, but the wage base for Social Security adjusts annually. Here are the 2026 rates and limits you need to know.

Social Security taxes

Both the employee and employer pay 6.2% on wages up to the 2026 Social Security wage base of $184,500. Once an employee earns more than $184,500 in a calendar year, neither party owes additional Social Security tax on wages above that limit. The maximum Social Security tax an employee will pay in 2026 is $11,439.

Medicare portion of FICA taxes

The Medicare tax rate is 1.45% for both the employee and employer, and it applies to all wages with no cap. Unlike Social Security, there's no upper limit on earnings subject to Medicare tax.

Additional Medicare tax for high earners

Employees who earn above certain thresholds owe an extra 0.9% Medicare surtax on wages exceeding those amounts. The thresholds are:

• $200,000 for single filers
• $250,000 for married couples filing jointly
• $125,000 for married individuals filing separately

This additional Medicare tax is paid only by the employee. Employers don't match the 0.9% surtax.

FICA taxes often get confused with income tax, but they serve different purposes and work differently. Understanding the distinction helps you manage your obligations more clearly.

FICA vs. income tax

While both FICA and income tax come out of an employee's paycheck, they fund different programs and follow different rules.

FICA is a flat-rate payroll tax that funds Social Security and Medicare. Every employee pays the same percentage regardless of income level (up to the Social Security wage base). Income tax, on the other hand, is a progressive tax that funds general government operations such as defense, infrastructure, and public services. Your income tax rate increases as your taxable income rises through different brackets.

Here are the key differences:

• FICA rates are fixed at 7.65% for all earners; income tax rates range from 10% to 37% depending on your bracket
• FICA applies to gross wages from the first dollar earned; income tax applies to taxable income after deductions and exemptions
• Employers match FICA contributions dollar for dollar; employers don't pay income tax on behalf of employees
• FICA funds specific benefit programs (Social Security and Medicare); income tax funds the federal government's general budget

Now that you understand how FICA differs from income tax, it's helpful to see the actual dollar amounts employers and employees each contribute on a typical salary.

Employer and employee contributions

Both the employer and employee share FICA costs equally. Here's an example of how contributions break down for an employee earning $50,000 per year:

• Social Security (employee): $50,000 x 6.2% = $3,100
• Medicare (employee): $50,000 x 1.45% = $725
• Total employee FICA: $3,825
• Social Security (employer match): $3,100
• Medicare (employer match): $725
• Total employer FICA: $3,825
• Combined annual FICA for this employee: $7,650

One important detail: the employer does not match the additional 0.9% Medicare surtax. If an employee's wages exceed the high-earner thresholds, only the employee pays that extra amount.

As the employer, your FICA contributions are a tax-deductible business expense. Make sure to account for them when budgeting for labor costs, since they add 7.65% on top of every employee's wages.

If you're self-employed, FICA works a bit differently. You're responsible for both the employee and employer shares, which changes how much you owe and what you can deduct.

What is FICA tax for small business owners?

When you're self-employed, you don't have an employer to split FICA costs with. Instead, you pay the full 15.3% through self-employment tax, which covers both the employee and employer portions of Social Security and Medicare.

This obligation comes from the Self-Employment Contributions Act (SECA) of 1954, which extended FICA-equivalent taxes to people who work for themselves. SECA applies if your net self-employment earnings reach $400 or more in a tax year.

If you operate as a sole proprietorship or an unincorporated LLC, you pay self-employment tax on your net business income. However, if you've elected S-corp status, you only pay FICA on the reasonable salary you pay yourself. The remaining profits pass through as distributions, which aren't subject to FICA. You can compare these structures in more detail when evaluating an S-corp vs. LLC setup. Owners of C-corporations are treated as employees and follow standard FICA withholding rules.

Deducting the employer portion

The IRS lets you deduct the employer-equivalent half of your self-employment tax, which helps offset the cost of paying both sides. Here's how the math works for $70,000 in net self-employment income:

1. Calculate your taxable self-employment earnings: $70,000 x 92.35% = $64,645 (the IRS applies this factor to approximate the employer share adjustment)
2. Calculate self-employment tax: $64,645 x 15.3% = $9,890.69
3. Your deduction for the employer portion: $9,890.69 / 2 = $4,945.35

You can claim this deduction on your tax return to reduce your adjusted gross income. For the full calculation method, see IRS instructions for Schedule SE.

While most workers and business owners pay FICA, certain groups qualify for exemptions. Knowing these exceptions helps you handle special payroll situations correctly.

FICA exemptions and special cases

Most employees and employers must pay FICA taxes, but the IRS grants exemptions in specific circumstances. Here are the main categories.

Churches and qualified church-controlled organizations

Certain churches and church-controlled organizations can apply for exemption from the employer share of FICA taxes by filing IRS Form 8274. Employees of exempt organizations may still owe self-employment tax on their earnings.

Certain religious groups

Members of recognized religious sects who are opposed to insurance benefits (including Social Security and Medicare) can apply for individual exemption by filing IRS Form 4029. This exemption means giving up eligibility for those benefits.

Students working for their school

Students enrolled at and employed by a college, university, or school may qualify for a FICA exemption on wages earned through that employment. The exemption generally applies when the student's primary relationship with the institution is educational, not employment-based. For details, see the IRS student exception to FICA tax.

Minors employed by parents

Children under 18 who work for a parent's sole proprietorship or a partnership where both partners are the child's parents are exempt from FICA taxes. This exemption doesn't apply if the parent's business is a corporation or if the child is 18 or older.

Certain foreign workers

Nonresident aliens on specific visa types, such as F-1, J-1, M-1, and Q-1 visas, may be exempt from FICA taxes during their initial period of stay. The exemption depends on visa category, residency status, and treaty provisions. Once a foreign worker becomes a resident alien for tax purposes, standard FICA rules apply.

FICA isn't just a tax; it's what earns you and your employees access to retirement and healthcare benefits later in life. Here's how the credits system works.

How FICA affects Social Security and Medicare eligibility

Every dollar you pay in FICA taxes counts toward your eligibility for Social Security retirement benefits and Medicare health coverage. The Social Security Administration (SSA) uses a credits-based system to track your qualifying work history.

You can earn up to four credits per year. In 2025, you earn one credit for every $1,810 in wages or self-employment income, up to a maximum of four credits annually. To qualify for Social Security retirement benefits, you need at least 40 credits, which works out to roughly 10 years of work.

Here's how the timeline looks for key benefits:

• Medicare eligibility begins at age 65, regardless of when you start collecting Social Security
• You can claim Social Security retirement benefits as early as age 62, though benefits are permanently reduced if you claim before your full retirement age
• Delaying benefits past your full retirement age increases your monthly payment, up to age 70

For self-employed individuals, the FICA taxes you pay through SECA count toward these same credits. Staying current on your self-employment tax helps protect your future benefits.

Staying on top of FICA taxes is a key part of running payroll. The right tools can help you manage calculations, deadlines, and filings with less manual work.

FAQs on FICA taxes

Here are answers to frequently asked questions about FICA taxes.

Is FICA the same as Social Security?

Not exactly. FICA is the law that authorizes payroll taxes for both Social Security and Medicare. Social Security is one of the two programs funded by FICA, covering retirement, disability, and survivor benefits. When people refer to "FICA taxes," they mean the combined Social Security and Medicare withholdings.

What happens if my business doesn't withhold FICA taxes?

Failing to withhold and deposit FICA taxes can result in significant penalties from the IRS, including the Trust Fund Recovery Penalty. This penalty can equal 100% of the unpaid taxes and may be assessed against the business owner personally. The IRS can also charge interest on late payments.

Can I opt out of paying FICA?

Most workers and employers cannot opt out of FICA. The only exceptions apply to specific groups, such as qualifying members of certain religious sects and some nonresident aliens on specific visa types. For the vast majority of businesses and employees, FICA is mandatory.

How does FICA work across multiple jobs?

Each employer withholds FICA independently, which means you could overpay Social Security tax if your combined wages from multiple jobs exceed the $184,500 wage base. If that happens, you can claim the excess Social Security tax as a credit when you file your tax return. Medicare tax has no cap, so there's no overpayment issue there.

Are bonuses and commissions subject to FICA?

Yes. Bonuses, commissions, and most other forms of supplemental pay are subject to FICA taxes at the same rates as regular wages. The Social Security wage base still applies, so if an employee has already exceeded $184,500 in year-to-date earnings, the bonus won't be subject to the 6.2% Social Security portion.

How do I handle FICA taxes on my employees' tips?

Employees must report cash tips of $20 or more per month to you, and those tips are subject to FICA withholding. You're responsible for withholding FICA taxes on reported tips and paying the employer match. For details on tip reporting and your obligations, see the IRS self-employment tax page.
