What can be done if an employer will not withhold income taxes, social security, and Medicare from my pay?

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. federal tax and social security law. Find out from your employer the reason that social security and Medicare taxes and income 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.

I am self-employed. How do I report my income and how do I pay Medicare and social security taxes?

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.

I received a Form 1099-MISC with an amount in box 7, (nonemployee compensation). What forms and schedules should be used to report income earned as an independent contractor?

Independent contractors report their income on Form 1040, Schedule C (PDF), Profit or Loss from Business (Sole Proprietorship), or you may qualify to use Form 1040, Schedule C-EZ (PDF), Net Profit from Business (Sole Proprietorship). You should also be aware of Form 1040, Schedule SE (PDF), Self-Employment Tax, which must be filed if net earnings from self-employment are $400 or more. This form is used to figure your social security and Medicare tax which is based on your net self-employment income. You may also need to file Form 2210, Underpayment of Estimated Tax by Individuals, Estates & Trusts, if you do not make estimated tax payments.

We hired a nanny to look after our baby while we work. How do we pay her social security taxes and properly report her income?

A nanny is considered a household employee. A household employer only has to pay social security and Medicare tax only for the employee(s) that receive $1,400 or more in cash wages for the year 2004. If the amount paid is less than $1,400, no social security or Medicare tax is owed. If social security and Medicare tax must be paid, you will need to file Form 1040, Schedule H, Household Employment Taxes. You must withhold the employee's portion of the social security and Medicare unless the employer chooses to pay both the employee's share and the employer's share.

The taxes are 15.3% of cash wages. Your share is 7.65% and the employee's share is 7.65%. You may also be responsible for paying federal unemployment taxes. For directions on household employees, refer to Publication 926, Household Employer's Tax Guide.

I am self-employed. How do I report my income and how do I pay Medicare and social security taxes?

Your self-employment income is reported on Form 1040, Schedule C (PDF), Profit or Loss from Business, or on Form 1040, Schedule C-EZ (PDF), Net Profit from Business.

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

As a self-employed person, you pay your Medicare and social security taxes the same way you pay your income taxes. If you expect to owe less than $1,000 in total taxes, you can pay them when you file your income tax return. If you expect to owe $1,000 or more in total taxes, you will need to make estimated tax payments. These payments are made quarterly using Form 1040-ES (PDF), Estimated Tax for Individuals. You will need to figure these taxes at the beginning of the year. To learn about figuring and making estimated tax payments, please refer to Publication 505, Tax Withholding and Estimated Tax.

Under my visa as a temporary nonresident alien, I'm not subject to social security and Medicare withholding. My employer withheld the taxes from my pay. What should I do to get a refund of my social security and Medicare?
