How To Calculate FICA Taxes

Understanding how to calculate FICA taxes is crucial for both employers and employees in the United States. FICA, which stands for the Federal Insurance Contributions Act, is a payroll tax used to fund Social Security and Medicare, the country's primary retirement and health care programs for retired individuals, disabled people, and the families of retired, disabled, or deceased workers. In this comprehensive guide, we’ll cover everything you need to know about calculating FICA taxes, providing you with detailed steps, examples, and addressing common misconceptions.

What Are FICA Taxes?

FICA taxes are mandatory taxes for employees and employers, established to fund Social Security and Medicare programs. Social Security benefits provide a source of income for individuals during their retirement and support for disabled individuals, while Medicare provides health insurance coverage for people aged 65 and older, as well as certain younger individuals with disabilities.

FICA is divided into two main components:

  • Social Security Tax: This is a payroll tax that funds the Social Security program. In 2023, the Social Security tax rate is 6.2% for both the employee and the employer, up to the wage base limit of $160,200. This means any earnings above this cap are not subject to Social Security tax.
  • Medicare Tax: This tax funds the Medicare program. The rate is 1.45% for both the employee and the employer on all earnings, with no cap. However, individuals earning more than $200,000 (or $250,000 for married couples filing jointly) have an additional 0.9% Medicare tax imposed only on the employee.

Calculating FICA Taxes: A Step-by-Step Guide

To calculate FICA taxes, you need to consider both the Social Security and Medicare components separately. Here’s how you can do it:

Step 1: Calculate Social Security Tax

  1. Determine Subject Wages: First, find out the total wages subject to Social Security tax. This generally includes gross wages, excluding any pretax deductions such as 401(k) contributions or flexible spending account (FSA) contributions.

  2. Apply Social Security Tax Rate: Multiply the subject wages by the Social Security tax rate (6.2%).

  3. Consider Wage Base Limit: Ensure that the taxed wages do not exceed the wage base limit ($160,200 for 2023). Any earnings above this amount are not taxed for Social Security.

Example:
Suppose an employee earns $100,000 annually.

  • Social Security Tax = $100,000 x 6.2% = $6,200

Example with Wage Base Limit:
An employee earns $170,000 annually.

  • Subject Wages = $160,200 (wage base limit)
  • Social Security Tax = $160,200 x 6.2% = $9,932.40

Step 2: Calculate Medicare Tax

  1. Determine Subject Wages: Again, calculate the total wages subject to Medicare tax. This follows the same calculation method as Social Security, but there's no wage cap.

  2. Apply Medicare Tax Rate: Multiply the subject wages by the Medicare tax rate (1.45%).

  3. Calculate Additional Medicare Tax: If the employee’s earnings exceed $200,000, calculate the Additional Medicare Tax by multiplying the excess amount over $200,000 by 0.9%.

Example:
Suppose an employee earns $100,000 annually.

  • Medicare Tax = $100,000 x 1.45% = $1,450

Example with Additional Medicare Tax:
An employee earns $250,000 annually.

  • Regular Medicare Tax = $250,000 x 1.45% = $3,625
  • Earnings above $200,000 = $50,000
  • Additional Medicare Tax = $50,000 x 0.9% = $450
  • Total Medicare Tax = $3,625 + $450 = $4,075

Step 3: Total FICA Tax

Add the total Social Security tax to the total Medicare tax to determine the overall FICA tax liability for the employee.

Example:
Continuing from the Social Security example where the employee earns $100,000:

  • Social Security Tax = $6,200
  • Medicare Tax = $1,450
  • Total FICA Tax = $6,200 + $1,450 = $7,650

Common Questions and Misconceptions

Why is my FICA tax different from my friend’s?

FICA taxes can differ based on the total earnings and how they relate to the Social Security wage base limit and the additional Medicare tax threshold. Variations in salary, bonuses, or other compensations can alter your tax liabilities.

Do employers pay FICA taxes, too?

Yes, employers are responsible for withholding the employee's portion and remitting this amount to the IRS alongside their share, effectively doubling the FICA tax rate to 15.3% (6.2% for Social Security plus 1.45% for Medicare for both employee and employer).

Are FICA taxes refundable?

Generally, FICA taxes are not refundable, as they fund future benefits. However, if an employer mistakenly withholds excess amounts due to exceeding the wage base limit across multiple jobs, an employee can claim a refund when filing their annual tax return.
