Generally, in situations such as this, the employer is not considering you to be an employee. Rather, you are being treated as an independent contractor (self-employed person). If you cannot resolve this matter with your employer, and if you feel that an employer-employee relationship exists, you should submit a Form SS-8 (PDF), Determination of Employee Work Status for Purposes of Federal Employment Taxes and Income Tax Withholding. The factors used to determine if an employer-employee relationship exists are covered in Chapter 2 of Publication 15-A (PDF), Employer's Supplemental Tax Guide.

If your status as an employee is not at issue, it may be that you are in a category of employment whose earnings are not defined as wages under U.S. social security law. Find out from your employer the reason that social security and Medicare taxes are not being withheld from your pay. If you have further questions, contact the IRS at 800-829-1040 or visit an IRS walk-in office for assistance.

Students who perform services for the school, college, or university where they are enrolled and regularly attend classes are usually not subject to social security and Medicare taxes.

If the student works for a public school, college or university which is subject to a section 218 agreement, the student's services are automatically subject to social security and Medicare taxes if the state has chosen to cover students under its section 218 agreement with the Social Security Administration. The employer can tell you whether its students' services are subject to social security and Medicare taxes under a section 218 agreement.

If you are not performing a service for the university, your stipend would be subject to income tax only if it does not meet the qualified scholarship rules. Please refer to Publication 520, Scholarships and Fellowships, for information on when a stipend would be a qualified scholarship, which would not be subject to social security and Medicare taxes. If you are performing a service for the university, your income is taxable for income tax purposes, but would generally be exempt from social security and Medicare taxes if you are enrolled and regularly attending classes unless you are covered under a section 218 agreement. Refer to Publication 15, Employer's Tax Guide.

If your employer has been withholding social security and Medicare taxes from your stipend, the employer should refund the withheld tax. If the employer refuses to do so, Form 843 (PDF), Claim For Refund and Request For Abatement, can be filed to claim credit for the incorrectly withheld tax.

The entire amount of a minister's housing allowance is subject to social security and Medicare taxes, even though it may be excluded from taxable income for income taxes. A minister's compensation for services as an employee, as well as from self-employment, is subject to Self-Employment Contributions Act (SECA) taxes, not the Federal Insurance Contributions Act (FICA). Under SECA the self-employed person pays all the taxes while under FICA the employer and employee each pay half of the taxes.

However, if you are a duly ordained Commissioned, or licensed minister, or member of a religious order not under a vow of poverty, or a Christian Science Practitioner who elected and was approved for exemption from Social Security coverage and self-employment tax, your housing allowance would not be subject to social security or Medicare taxes under SECA.

You are a sole proprietor if you are the sole owner of a business that is not a corporation. Report your income and expenses from your sole proprietorship on Form 1040, Schedule C (PDF), Profit or Loss from Business (Sole Proprietorship), or on Form 1040, Schedule C-EZ (PDF), Net Profit from Business.

If the total of your net profit from all businesses is $400 or more, you must pay into the Social Security and Medicare systems by filing Form 1040, Schedule SE (PDF), Self-Employment Tax. Self-Employment tax consists of the Old-Age, Survivors, and Disability Insurance (social security) and the Hospital Insurance (Medicare) taxes. For more information on this, refer to Publication 533, Self-Employment Tax.

The Federal tax system is based on a pay-as-you-go plan. Tax is generally withheld from your wages or salary before you get it. However, tax is generally not withheld from self-employment income. Thus, you may be required to make estimated tax payments. Publication 505, Tax Withholding and Estimated Tax, provides information on making estimated tax payments.

The determination is complex, but is essentially made by examining the right to control how, when, and where the person performs services. It is not based on how the person is paid, how often the person is paid, nor whether the person works work part-time or full-time. There is no statutory definition of what an employee is, but from common law three basic areas have been identified:

For more information on employer-employee relationships, refer to Chapter 2 of Publication 15-A (PDF), Employer's Supplemental Tax Guide. If you would like the IRS to determine whether services are performed as an employee or independent contractor, you may submit Form SS-8 (PDF), Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding.

Unless you have requested a determination by filing Form SS-8, you generally have to report your nonemployee compensation on Form 1040, Schedule C (PDF), Profit or Loss from Business (Sole Proprietorship), or Form 1040, Schedule C-EZ (PDF), Net Profit from Business. You also need to complete Form 1040, Schedule SE (PDF), Self-Employment Tax, and pay self-employment tax on your net earnings from self-employment, if you had net earnings from self-employment of $400 or more. This is the method by which self-employed persons pay into the social security and Medicare trust funds. Generally, there are no tax withholdings on this income. Thus, you may have been subject to the requirement to make quarterly estimated tax payments. If you did not make timely estimated tax payments, you may be assessed a penalty for an underpayment of estimated tax. Employees pay into the social security and Medicare trust funds, as well as income tax withholding, through payroll deductions.

Your Medicare and social security taxes are reported on Form 1040, Schedule SE (PDF), Self-Employment Tax.
