Social Security Tax, often referred to as OASDI (Old-Age, Survivor’s, and Disability Insurance) tax, is a crucial component of the United States tax system. It is assessed on compensation and self-employment earnings under the Federal Insurance Contributions Act (FICA). This tax ensures funding for Social Security benefits, which include retirement, disability, and survivors’ benefits.
Components of OASDI
Employer and Employee Contributions
The OASDI tax rate is 12.4% of earnings, with a cap on the amount of earnings subject to the tax. For example, in 2011, the cap was set at $106,800. Employers and employees share this tax burden equally. Employers withhold 6.2% from employees’ wages and contribute an additional 6.2% as a matching contribution. These are then deposited with the IRS at regular intervals.
Self-Employment Contributions
Self-employed individuals are responsible for the full 12.4% OASDI tax on their earnings. They must include the tax with their quarterly estimated income tax payments.
Calculation Example
Consider an employee earning $50,000 annually. The employee’s OASDI tax contribution would be:
The employer would also contribute $3,100, making the total OASDI tax $6,200.
Historical Context
The Social Security Act was signed into law by President Franklin D. Roosevelt in 1935. The OASDI program was designed to provide permanent and continuing income for workers and their families in the event of retirement, disability, or death. Over the decades, the structure of the tax has evolved to accommodate changing economic conditions.
Applicability
- Salaried Workers: OASDI applies to wages earned.
- Self-Employed Individuals: Applies to net earnings from self-employment.
- Income Cap: There is a maximum earning threshold subject to OASDI.
Comparison with Medicare Tax
While OASDI and Medicare Taxes are both under FICA, they serve different purposes and have different tax rates. The Medicare tax rate is 2.9% of all wages, with no income cap, split equally between employer and employee (1.45% each).
