What Is Self-Employment Tax

What is Self-Employment Tax?

Self-employment tax (SE tax) is a social security and Medicare tax primarily for individuals who work for themselves. It is similar to the social security and Medicare taxes withheld from the pay of most wage earners.
You figure SE tax yourself using Schedule SE (Form 1040). Social security and Medicare taxes of most wage earners are figured by their employers. Also you can deduct half of your SE tax in figuring your adjusted gross income. Wage earners cannot deduct social security and Medicare taxes.
SE tax rate. The self-employment tax rate is 15.3%. The rate consists of two parts: 12.4% for social security (old-age, survivors, and disability insurance) and 2.9% for Medicare (hospital insurance).
Maximum earnings subject to SE tax. Only the first $94,200 of your combined wages, tips, and net earnings in 2006 is subject to any combination of the 12.4% social security part of SE tax, social security tax, or railroad retirement (tier 1) tax.
All your combined wages, tips, and net earnings in 2006 are subject to any combination of the 2.9% Medicare part of SE tax, social security tax, or railroad retirement (tier 1) tax.
Fiscal year filer. If you use a tax year other than the calendar year, you must use the tax rate and maximum earnings limit in effect at the beginning of your tax year. Even if the tax rate or maximum earnings limit changes during your tax year, continue to use the same rate and limit throughout your tax year.
Self-employment tax deduction. You can deduct half of your SE tax in figuring your adjusted gross income. This deduction only affects your income tax. It does not affect either your net earnings from self-employment or your SE tax.


How to Pay Self-Employment Tax:
To pay SE tax, you must have a social security number (SSN) or an individual taxpayer identification number (ITIN). This section explains how to:
1.Obtain an SSN or ITIN
2.Pay your SE tax using estimated tax.

Obtaining a Social Security Number. If you never had an SSN, apply for one using Form SS-5, Application for a Social Security Card. You can get this form at any Social Security office or by calling (800) 772-1213. Download the form from the Social Security Online Web site.
Obtaining an Individual Taxpayer Identification Number. The IRS will issue you an ITIN if you are a nonresident or resident alien and you do not have and are not eligible to get an SSN. To apply for an ITIN , file Form W-7, Application for IRS Individual Taxpayer Identification Number.

cEstimated Taxes
Federal income tax is a pay-as-you-go tax. You must pay the tax as you earn or receive income during the year. You generally have to make estimated tax payments if you expect to owe tax, including SE tax, of $1,000 or more when you file your return. There are two ways to pay as you go: withholding and estimated taxes. If you are a self-employed individual and do not have income tax withheld, you must make estimated tax payments.
