Social Security tax, also known as the Old Age, Survivors, and Disability Insurance (OASDI) tax, is an essential part of the American retirement and disability system. Understanding how it is calculated can help individuals manage their income and plan for their financial future. This article breaks down the Tax structure, including how it applies to employees, employers, and self-employed individuals, as well as important elements like the income cap and tax adjustments over time.
Understanding Social Security Tax
What Is Social Security Tax?
Tax is a federal payroll tax collected to fund the Social Security program. This program provides benefits for retirees, survivors, and those with disabilities. Both employers and employees contribute a portion of their income to this tax. Self-employed individuals are responsible for paying both portions, as they don’t have an employer to match their contributions.
How Is Social Security Tax Calculated?
Tax is calculated as a percentage of a worker’s income. For employees, the tax rate is set at 6.2% for 2024. Employers match this contribution, making the total tax rate 12.4%. Self-employed individuals pay the full 12.4% themselves because they act as both employer and employee.
