DEFINITION:

FICA is a federal law requiring payroll tax withholding to fund Social Security and Medicare programs for eligible employees.
The Federal Insurance Contributions Act (FICA) is a United States federal law that requires employers to withhold specific payroll taxes from employee wages to fund Social Security and Medicare programs. Both employers and employees contribute equal portions of these taxes, which are then remitted to the federal government. The Social Security portion helps provide retirement, disability, and survivor benefits, while Medicare supports health insurance for individuals aged 65 or older and certain younger people with disabilities. FICA tax rates and wage bases are periodically adjusted by the government. Nonprofit organizations must also comply with FICA requirements, unless specifically exempt, making accurate payroll processing and reporting essential.

Key Takeaways

  • FICA funds Social Security and Medicare through payroll taxes.
  • Employers and employees both contribute to FICA taxes.
  • Nonprofits must generally comply unless specifically exempt.
  • Accurate payroll processing ensures legal compliance.

Why It Matters

FICA ensures funding for Social Security and Medicare and is legally required for most organizations with employees.

Real World Example

A local animal rescue nonprofit employs five staff members. Each pay period, the organization uses payroll software to calculate FICA taxes, withholding a percentage from each employee’s wages for Social Security and Medicare. The nonprofit also matches these withholdings with an equal employer contribution. At the end of the quarter, the organization files payroll tax reports and remits the total FICA taxes to the IRS. By accurately processing FICA, the nonprofit ensures compliance with federal law and contributes to the long-term financial security and healthcare of its employees.
