Self-employment tax refers to the tax obligation that self-employed individuals are required to pay on their net earnings from self-employment. It is a form of tax that is distinct from other types of taxes, such as
income tax or
payroll tax. Understanding the nature of self-employment tax and its differences from other taxes is crucial for individuals who are self-employed or considering venturing into self-employment.
Self-employment tax is primarily governed by the United States Internal Revenue Service (IRS) and is designed to fund
Social Security and Medicare programs. The tax is calculated based on the net earnings of self-employed individuals, which is determined by subtracting allowable
business expenses from their
gross income. These business expenses can include costs related to operating the business, such as rent, supplies, and equipment.
The self-employment tax rate consists of two components: the Social Security tax and the Medicare tax. As of 2021, the Social Security tax rate is set at 12.4% on net earnings up to a certain threshold, which is subject to annual adjustments. However, only a portion of the net earnings is subject to the Social Security tax. For the 2021 tax year, the threshold is $142,800. Any net earnings above this threshold are not subject to the Social Security tax.
The Medicare tax rate is set at 2.9% on all net earnings, with no income threshold. Unlike the Social Security tax, there is no cap on the amount of net earnings subject to the Medicare tax. Additionally, high-income earners may be subject to an additional 0.9% Medicare surtax on earnings above certain thresholds.
One key distinction between self-employment tax and other types of taxes is that self-employed individuals are responsible for paying both the employer and employee portions of Social Security and Medicare taxes. In traditional employment settings, employers typically withhold and contribute the employer portion of these taxes on behalf of their employees. However, self-employed individuals must calculate and pay both portions themselves, resulting in a higher overall tax burden.
Another difference is that self-employment tax is calculated on net earnings from self-employment, whereas income tax is calculated on taxable income, which takes into account various deductions, exemptions, and credits. Self-employed individuals are still required to pay income tax in addition to self-employment tax, but the calculation methods and rates differ.
Furthermore, self-employment tax is distinct from
payroll tax, which is the tax withheld from an employee's wages by their employer. Payroll tax includes Social Security tax, Medicare tax, and other taxes such as federal and state income tax withholding. Self-employed individuals do not have an employer withholding these taxes for them, so they must calculate and pay them separately.
In summary, self-employment tax is a specific type of tax that self-employed individuals must pay on their net earnings from self-employment. It differs from other types of taxes, such as income tax and payroll tax, in terms of calculation methods, rates, and the responsibility of paying both the employer and employee portions of Social Security and Medicare taxes. Understanding these distinctions is crucial for self-employed individuals to fulfill their tax obligations accurately and efficiently.
