W-9

A form filed with the IRS stating a person or company's Social Security number or Tax Identification Number, and listing all the income that the filer has paid to the person or company he/she regard. This income may be ordinary income, dividends, or something else. The W-9 form states that the person or company is not subject to withholding. That is, it states that the party making payments is not responsible for withholding income for taxes, and places the onus on the person or company the form regards. W-9 forms are frequently used for independent contractors.
