Individuals can obtain a blank copy of Internal Revenue Service Form W-9 by downloading a PDF copy from the agency's website, according to instructions provided by the IRS. A person or entity that needs tax information provided by Form W-9 from another individual or entity can simply ask the party to provide a completed and signed form during the course of their transaction.
IRS Form W-9, Request for Taxpayer Identification Number and Certification, details the taxpayer identification number, also called a Social Security number or an employer identification number, of an individual or business that receives payments or income that must be reported to the IRS, according to Intuit TurboTax. The information included on Form W-9 enables the payer to prepare paychecks for employees or cut checks to independent contractors and report those payments to the IRS at the end of the year in a way that the agency can track.
Other instances in which a party, such as a bank, may request Form W-9 from a taxpayer include the need to report mortgage interest paid, acquisition or abandonment of secured property, and cancellation of debt or contributions made to an IRA, as explained by the IRS. The individual or entity providing the Form W-9 can develop and use a substitute form, as long as its content is substantially similar to the official IRS form.
