Self-employment tax is a tax consisting of the Social Security and Medicare taxes primarily for individuals who work for themselves. It covers contributions to both Social Security (old-age, survivor’s, and disability insurance) and Medicare (hospital insurance).
Components of Self-Employment Tax§
Social Security Tax§
The Social Security portion of the self-employment tax helps fund the Social Security benefits that cover retirement, disability, and survivors’ benefits. For self-employed individuals:
- 2011 Rate: 10.4% on net earnings from self-employment up to $106,800.
- 2012 and Beyond: 12.4% on net earnings up to the Social Security wage base limit.
Medicare Tax§
The Medicare portion of the self-employment tax helps fund hospital insurance (Medicare Part A). For self-employed individuals:
- 2011 Rate: 2.9% on total net earnings from self-employment.
- 2012 and Beyond: Remains at 2.9% on total net earnings.
Historical Context and Rate Changes§
In 2011, the Social Security rate was temporarily reduced to 10.4% as part of an economic measure to stimulate the economy. Typically, the combined self-employment tax rate is 15.3%, which comprises 12.4% for Social Security and 2.9% for Medicare. This rate matches the total contributions made by both an employer and an employee.
Calculation and Payment of Self-Employment Tax§
Self-employed individuals calculate their self-employment tax using Schedule SE (Form 1040). The tax is then added to their income tax on Form 1040.
Example Calculation§
For an individual with $50,000 in self-employment net earnings in 2012:
- Social Security Tax: USD.
- Medicare Tax: USD.
- Total Self-Employment Tax: USD.
Estimated Tax Payments§
Self-employed individuals must make estimated tax payments quarterly if they anticipate owing at least $1,000 in self-employment tax.
Special Considerations§
Deductions for Self-Employment Tax§
A self-employed individual can deduct the employer-equivalent portion of the self-employment tax. This deduction only affects their income tax, not the self-employment tax.
Thresholds and Limits§
While Medicare tax is applied to all net earnings, the Social Security tax only applies up to a certain limit, known as the wage base limit, which can change annually based on national average wage indexes.
