The IRS Form W-14 is the official request for a taxpayer identification number (TIN) when filing certain information returns. Whether you are a business, a payer, or an individual, the form must be completed accurately to avoid processing delays.

What Is Form W-14?

Form W-14 is used to request a Social Security Number (SSN) or Employer Identification Number (EIN) for entities that do not have one. The form is typically attached to other IRS filings such as Forms 1099, 1098, and 941.

• Leaving the "Signature" field blank – a handwritten signature is required.

• Omitting the payer’s name or address, which can cause rejection.
• Failing to check the appropriate box for SSN vs. EIN.
