Payroll taxes are mandatory contributions that employers and employees must pay to fund various government programs. These taxes are typically deducted from an employee's paycheck and include contributions for Social Security, Medicare, and federal and state unemployment insurance. The employer also matches a portion of these taxes, which helps support social safety nets. The revenue generated from payroll taxes is crucial for funding essential services and benefits. For instance, Social Security provides financial assistance to retirees and disabled individuals, while Medicare offers health coverage for seniors. These taxes ensure that workers contribute to the systems that support them and their families in times of need.
