Understanding the Context

How What Is Payroll Tax Actually Works
Payroll tax refers to the taxes withheld from employee wages and matched by employers, primarily to fund critical U.S. social programs. Most commonly, these include Social Security and Medicare taxes—officially known as Federal Insurance Contributions Act (FICA) taxes. Employees contribute 6.2% for Social Security and 1.45% for Medicare, both as a percentage of gross pay, split between worker and employer. For self-employed individuals or gig workers, these rates are fully borne by them.

Beyond FICA, certain state-level payroll taxes apply, varying by jurisdiction, but FICA remains the backbone. Employers accurately calculate, collect, and remit these taxes to the IRS and state agencies, ensuring steady funding for benefits available to current and future generations.
