Taxpayers use the W-9 tax form to give their tax identification or Social Security numbers to employers or individuals who must report to the IRS any income they pay a taxpayer, notes the IRS. Examples of items that have to be reported to the IRS on an information return, besides income, include real estate transactions, cancellation of a debt, paid mortgage interest, IRA contributions, and abandonment or acquisition of a secured property.
Nonresident aliens in the United States who don't have a Social Security number have to use a taxpayer identification number when completing a W-9, according to TurboTax. Those who have an employer identification number because they operate their own businesses should use that number on the W-9 form in the EIN space.
There are cases where the IRS requires the company or individual asking for a W-9 form to withhold a portion of the taxpayer's income, which is known as backup withholding, notes TurboTax. A taxpayer is notified before a portion of his wages is withheld.Learn more about Taxes
