What Is a W-9 Form? Definition and Purpose

IRS Form W-9, officially titled “Request for Taxpayer Identification Number and Certification,” serves as a critical tax document that provides your taxpayer identification number (TIN) to entities that must report income paid to you. Unlike tax returns, the W-9 form is never filed with the IRS – it’s retained by the requester for their records and 1099 preparation.

The w-9 form is a straightforward document that simplifies the reporting process.

The W-9 form collects essential information including:

  • Legal name (as shown on your income tax return)
  • Business name/DBA (if applicable)
  • Federal tax classification (individual/sole proprietor, LLC, corporation, etc.)
  • Taxpayer Identification Number (SSN or EIN)
  • Current mailing address
  • Certification signature and date

This information enables businesses to accurately report payments on Form 1099-NEC, 1099-MISC, and other information returns.

Using the w-9 form correctly can help prevent unnecessary complications during tax season.

When Is a W-9 Form Required? Common Scenarios

A W-9 form request typically occurs when starting new business relationships or when payments exceed $600 annually. Businesses require W-9 forms to comply with IRS reporting requirements and avoid backup withholding penalties.

Providing a w-9 form promptly can facilitate smoother transactions and maintain good business relations.
