W-9 Form Overview
The W-9 form, officially titled "Request for Taxpayer Identification Number and Certification," is an IRS form used in the United States to collect tax information from independent contractors, freelancers, and vendors.
When a business pays someone $600 or more during a tax year for services, they must report those payments to the IRS using Form 1099. The W-9 provides the information needed to complete that 1099.
Who Needs to Fill Out a W-9?
- Independent contractors providing services to businesses
- Freelancers working with clients
- Vendors selling products or services
- Self-employed individuals receiving payments
- LLCs and partnerships doing business with other companies
Information Required on a W-9
- Legal name (as shown on tax return)
- Business name (if different)
- Federal tax classification (individual, LLC, corporation, etc.)
- Address
- Taxpayer Identification Number (SSN or EIN)
- Certification signature
Why Businesses Request W-9 Forms
Businesses need W-9 forms to comply with IRS reporting requirements. Without the correct taxpayer information, businesses may be required to withhold 24% of payments for backup withholding.
Collecting W-9s at the start of a business relationship ensures smooth year-end tax reporting and avoids delays in payments.
