A W-9 is a United States tax form issued by the Internal Revenue Service (IRS) and used to collect a person’s or business’ tax identification information. It is typically completed by independent contractors, freelancers, and vendors who provide services to a US-based organisation.
The information provided on a W-9 enables the payer to report payments correctly to the IRS for tax purposes.
A W-9 is requested by a company before making payments to a U.S. individual or business. Key elements include:
- Taxpayer information: legal name and business name (if applicable).
- Tax classification: individual, sole proprietor, partnership, or corporation.
- Tax identification number: Social Security number (SSN) or Employer Identification Number (EIN).
- Certification: confirmation that the information provided is accurate.
The completed W-9 is retained by the payer and is not submitted to the IRS, unless requested during an audit.
A W-9 is commonly required when:
- A company pays a U.S.-based independent contractor or freelancer
- Professional services are provided by a U.S. individual or entity
- Reportable payments must be disclosed to the IRS
- Vendor or supplier information is being verified.
Using a W-9 helps ensure correct tax reporting and prevents backup withholding where applicable.
- W-9: used by U.S. persons or U.S.-based entities.
- W-8 forms: used by non-U.S. individuals or businesses to certify foreign status.
Correctly identifying which form to use is essential for compliant cross-border payments.
