FICA Made Simple

Learn what FICA tax is, how to calculate it, who pays, and which wages are exempt. Covers Social Security, Medicare, 401(k) tax rules, and payroll basics.

You may be overpaying your payroll taxes without even realizing it.

Every time you run payroll, your business pays a matching share of your employees’ Social Security and Medicare taxes, whether they’re earning hourly wages, salaries, commissions or even customer tips. For many employers, these taxes are just another line item in the payroll process. 

It’s called the FICA tax, and it applies to nearly every dollar earned by your regular employees. That includes base wages, overtime, bonuses and yes, even tips. You’re responsible for contributing 7.65 percent of each employee’s taxable wages to the government, on top of what they earn.

However, qualifying employers in the food and beverage industry, including restaurants, bars, and hospitality businesses, may be eligible for significant savings thanks to the FICA Tip Credit. The IRS may owe you thousands of dollars back on those taxes if you know how to claim them.

What Is FICA, Really?

FICA stands for the Federal Insurance Contributions Act, which is a federal payroll tax that shows up on every paycheck and is split between you (the employer) and your W-2 employees, a traditional or regular employee who is on your payroll. 

The FICA tax rate is applied to all taxable compensation, including:

  • Salary and wages
  • Tips reported by employees
  • Bonuses and commissions
  • Taxable fringe benefits

For detailed guidance, refer to IRS Publication 15-B, which includes a chart outlining which fringe benefits are subject to FICA taxes and which are exempt (see Table 2-1 on page 6).

Also, keep in mind that employee contributions to retirement plans, such as 401(k)s, are still subject to FICA taxes, even though they may be excluded from federal income tax.

What Does FICA Fund?

FICA funds two major social programs that support millions of Americans:

  • Social Security: Retirement, disability and survivor benefits
  • Medicare: Health coverage for people aged 65 or older or certain younger people with disabilities

When you and your employees pay FICA, you're funding these programs, which serve over 180 million workers in the United States.

Who pays FICA taxes​?

Both the employer and employee are responsible for paying:

Note: High earners pay an additional 0.9% Medicare surtax on wages exceeding $200,000; however, only employees pay this tax, not employers.

Real-World Example

Let’s say you run payroll for an employee who earns $1,000 in a week:

  • Employee pays:

    • $62 (Social Security)
    • $14.50 (Medicare)
    • Total: $76.50 withheld

  • Employer pays (you):

    • $62 (Social Security)
    • $14.50 (Medicare)
    • Total: $76.50 from your business

That’s $153 in FICA taxes just for one employee that week, and this repeats every week, for every W-2 worker on payroll.

Now imagine the numbers across your entire staff and year after year. It adds up.

What Is the FICA Withholding Process?

As an employer, you’re responsible for collecting and submitting FICA taxes on behalf of both your business and your employees. This isn’t optional. It’s part of your legal payroll obligations.

Every time you run payroll, you must:

  1. Withhold the employee’s share of FICA taxes (7.65 percent)
  2. Match that amount with an equal contribution from your business
  3. Submit the total to the IRS, typically through your payroll service or Form 941

Once received, the IRS allocates those funds:

  • To the Social Security Administration to fund retirement, survivor and disability benefits
  • To the Medicare Trust Fund, which supports healthcare for seniors and qualified individuals with disabilities

FICA might look like just another tax line on a paycheck, but it's how nearly every American earns credit toward Social Security and Medicare coverage.

How To Calculate FICA Tax Rate

FICA tax follows a fixed percentage applied to eligible compensation. Getting this right ensures your payroll is both accurate and compliant.

Step 1: Identify FICA-Eligible Compensation

FICA applies to most taxable income, including:

  • Salaries, hourly wages, commissions and bonuses
  • Reported tips
  • Taxable fringe benefits (like moving expense reimbursements or gift cards)
  • Salary reductions for contributions to retirement plans like 401(k)s

Even if certain amounts are exempt from income tax, they may still be subject to FICA withholding.

Step 2: Apply the Social Security Wage Base Limit

For 2025, the Social Security tax only applies to the first $176,100 of an employee’s wages. Anything above that is not taxed for Social Security, but the Medicare tax continues to apply with no income cap.

Here’s how it breaks down:

  • For earnings up to $176,100, apply the full 6.2 percent Social Security rate
  • Beyond that threshold, stop withholding Social Security but continue the 1.45 percent Medicare tax on all additional income

Step 3: Match Employee Contributions

As the employer, you must match the exact amount of FICA tax withheld from each employee. If your employee pays $153 in FICA taxes this pay period, your business pays an additional $153 as well.

This dollar-for-dollar match is what often surprises business owners because your real payroll costs are higher than just base wages.

Who Is Exempt from FICA Taxes?​

While most employee compensation is subject to FICA taxes, there are several situations where FICA withholding is not required. Understanding these exemptions can help employers stay compliant while potentially reducing payroll tax liability.

It's important to note that FICA exemption rules can vary by state and are subject to specific IRS definitions and conditions. What qualifies in one setting may not apply in another, so always consult IRS publications or a payroll professional to confirm eligibility.

Below are some of the most common FICA exemptions employers should be aware of.

Common FICA-Exempt Scenarios

  • Payments to partners: Compensation paid to individuals who have general or limited partnership status is not subject to FICA. Partners typically report self-employment income instead.
  • Employer contributions to retirement plans: Contributions made by the employer to qualified retirement plans, such as a 401(k), Savings Incentive Match Plan for Employees individual retirement account (SIMPLE IRA) or Simplified Employee Pension (SEP) IRA, are not subject to FICA taxes.
  • Statutory nonemployees: Certain workers, such as qualified real estate agents or direct sellers, may meet the IRS definition of a statutory nonemployee. If properly classified, their earnings are not subject to FICA withholding.
  • Student employees working at their school: Wages paid to students who are enrolled and regularly attending classes at the same educational institution where they work may be exempt from FICA. This often applies to university work-study programs.
  • Low-tip thresholds: If an employee earns less than $20 in tips during a calendar month, those tips are not subject to FICA taxes.
  • Family employment in sole proprietorships or partnerships
    Wages paid to children under age 18 who are working for their parents’ sole proprietorship or a partnership where both parents are partners may be exempt from FICA.
  • Certain nonresident aliens: Some compensation paid to non-U.S. residents working in the U.S. under specific visa categories may be exempt. The eligibility depends on visa status, residency tests and IRS guidance.

Ready to Take Control of Your FICA Taxes?

FICA might be a mandatory part of payroll, but that doesn’t mean you’re stuck paying more than you should. If your business operates in food service, hospitality or any industry where tips are part of the equation, you may be eligible to claim back thousands in overpaid taxes.

You’ve already done the hard part: Employing staff, running payroll and reporting income. Now it’s time to see if the IRS owes you something in return.

Frequently Asked Questions (FAQs)

Is FICA the same as federal income tax?

No, FICA is separate from federal income tax. FICA taxes fund Social Security and Medicare programs, while federal income tax goes into the general federal budget and supports a broad range of government services. Both are withheld from employee paychecks, but they serve different purposes and follow other rules.

What are FICA taxes used for?

FICA taxes are used to fund two key federal programs:

  • Social Security, which provides retirement, disability and survivor benefits 
  • Medicare, which covers healthcare costs for people aged 65 and older as well as certain individuals with disabilities

When you and your employees pay FICA taxes, you're contributing directly to these safety net programs.

Are 401(k) contributions subject to FICA tax?

Yes, 401(k) contributions are subject to FICA tax. While employee contributions to a 401(k) plan are exempt from federal income tax, they are not exempt from FICA. That means Social Security and Medicare taxes must still be withheld on those earnings, even though income tax is deferred.

How much FICA tax is withheld?

The total FICA tax rate is 15.3 percent, split evenly between the employee and the employer:

  • Social Security: 6.2 percent (applies to wages up to $176,100 in 2025)
  • Medicare: 1.45 percent (applies to all wages with no cap)

Employees have 7.65 percent withheld from their wages, and employers contribute a matching 7.65 percent. High earners may pay an additional 0.9 percent Medicare tax on income above $200,000, but that additional amount is paid by the employee only.
