IRS Form W-9 (Request for Taxpayer Identification Number and Certification) is a standard tax document used by businesses to collect taxpayer information from vendors, independent contractors, and freelancers. When you start working with a new client or company, they will typically request a completed W-9 before making any payments that need to be reported to the IRS.
The form collects your name, address, and Taxpayer Identification Number (TIN), which is either your Social Security Number (SSN) or Employer Identification Number (EIN). The payer uses this information to prepare IRS Form 1099 at the end of the tax year, reporting how much they paid you during the calendar year.
Unlike many other tax forms, the W-9 is not filed with the IRS. You give the completed form directly to the business or individual who requested it, and they keep it on file for at least four years for their records. If you earn $600 or more from a single payer in a tax year, they are required to file a 1099-NEC and will need your W-9 to do so.
Any US person receiving reportable payments must provide a W-9 to the payer.
If you perform services for businesses as a non-employee, you must provide a W-9 so the payer can report your earnings on a 1099-NEC.
Whether you're a writer, designer, developer, or consultant, clients need your W-9 to properly report payments for tax purposes.
Sole proprietors and self-employed professionals must provide a W-9 when receiving reportable income from business clients.
Any vendor or supplier providing services (not goods) to a business must complete a W-9 before receiving payment for those services.
If you receive payments that are not wages (no W-2), you are likely receiving non-employee compensation and need to provide a W-9.
TIN (Taxpayer Identification Number) is the unique number the IRS uses to identify taxpayers. On a W-9, you can provide either a Social Security Number (SSN) for individuals or an Employer Identification Number (EIN) for businesses. Both are 9-digit numbers, but they serve different purposes and are issued by different agencies.
Your SSN is issued by the Social Security Administration and is typically used by individual contractors and sole proprietors. Your EIN is issued by the IRS and is used by businesses, partnerships, and corporations. Many freelancers and small business owners prefer to use an EIN instead of their SSN on W-9 forms for privacy reasons, as it keeps your Social Security Number off vendor databases.
You can apply for an EIN directly from the IRS at irs.gov. The application is free, takes about 10 minutes, and you receive your EIN immediately online. There is no cost to apply for an EIN, and you should never pay a third-party service to obtain one.
These forms are commonly used alongside the W-9 for tax reporting and compliance.

Ensures the legal name on Line 1 matches IRS records exactly. Flags mismatches between name and TIN before submission.
Confirms exactly one classification box is checked on Line 3 and that it is correct for the entity type. Validates LLC code letters.
Validates the TIN format: SSN as 9 digits or EIN as XX-XXXXXXX. Detects transposed digits and common input errors.
Verifies the form is signed and dated in Part II. A W-9 is invalid without a signature under penalty of perjury.
These are the most common mistakes when filling out W-9 forms.
The most common error. Your name on Line 1 must match exactly what the IRS has on file. A mismatch can trigger backup withholding for the payer.
Confusing SSN with EIN, or transposing digits, causes processing failures. Verify your TIN against your Social Security card or IRS CP 575 letter.
A single-member LLC uses the owner's SSN and should check "Individual/Sole Proprietor," not the LLC box with an entity EIN.
The form is legally invalid without a signature and date in Part II. This is a frequent oversight that forces re-submission.
Your legal name is required. Leaving it blank or using a nickname instead of your full legal name will cause the form to be rejected.
You do not send a W-9 to the IRS. Give it to the payer who requested it. The payer keeps it on file for their records.
