The W-9 tax form is called Request for Taxpayer Identification Number and Certification. It is required to supply information for a variety of tax filings, including income tax forms. The W-9 is used to provide correct taxpayer identification numbers to people or entities who are required to file an information return with the IRS. Employers use W-9 forms to gather name, address and social security or taxpayer identification numbers from independent contractors in order to fill out Form 1099. W-9 forms are not filed with the IRS.
