The IRS Form W-9 (Request for Taxpayer Identification Number and Certification) is used by individuals and businesses to provide their correct Taxpayer Identification Number (TIN) and Chapter 3 tax classification to a person or entity that is required to file an information return with the IRS.
For example, John Doe is a U.S. citizen and resident of Florida. John opens a savings account with Bank ABC. Bank ABC requests John to complete a Form W-9 to verify his name, address, and social security number (SSN). The bank uses the information to report the amount of interest income paid to John on Form 1099-INT (Interest Income). If the bank did not receive a correct Form W-9, it may subject John to backup withholding.
Information Required on Form W-9
- Name and address of the individual, entity, or trust
- Federal tax classification (individual, C corporation, S corporation, Partnership, Trust or Estate
- If the entity is a limited liability company (LLC), indicate the tax classification of the LLC
- The taxpayer identification number (TIN) for the individual or entity (entities use their employer identification number (EIN) and individuals use their SSN)
The taxpayer must sign and date the certification in Part II. Failure to provide a completed and accurate Form W-9 may result in backup withholding on the taxpayer.
