The IRS website notes taxpayer identification numbers are used by the agency in the enforcement of tax rules and laws. A social security number can be used as one form of tax ID number. As a business owner you will probably need a tax ID number besides your social security number. A self-employed, sole proprietor with no other employees can file her business taxes using her social security number as a business tax identification number.
Use Form W-9 to collect the taxpayer ID number or Social Security number of any U.S. person you plan to engage in a business activity. Use a Form W-8 for foreign entities or individuals, or Form W-7 for individuals who become U.S. residents for tax purposes but who aren't eligible for a Social Security number.
