What is Payroll Tax?

Payroll Tax

Quick Answer

A payroll tax is a tax that employers are required to withhold from their employees' earnings. It is used to fund social insurance programs, such as Social Security and Medicare.

Overview

Payroll tax is a deduction taken from an employee's paycheck, which helps fund government programs that provide benefits like retirement and healthcare. When you earn money from your job, a portion of your salary is automatically taken out and sent to the government. This tax is typically shared between the employee and the employer, meaning both parties contribute to the overall amount that goes toward these essential services. The way payroll tax works is fairly straightforward. For example, if you earn $1,000 in a week, a percentage of that amount, usually around 7.65% for Social Security and Medicare, will be withheld from your paycheck. Your employer matches this amount, meaning they also contribute an additional 7.65% on top of your earnings, making the total contribution to payroll tax 15.3% of your earnings. Understanding payroll tax is important because it directly impacts the benefits you receive later in life. For instance, the funds collected through payroll taxes are used to pay for Social Security benefits when you retire. If fewer people pay these taxes, it can affect the availability of these benefits for future generations.
