What is the W-9 form?
The IRS's Form W-9, Request for Taxpayer Identification Number and Certification, is a tax form used by US businesses to get information from independent contractors (or freelancers) based in the United States.
If you need a reminder of what this form is, read our blog article here.
The purpose of the W-9 Form is to collect information from vendors US clients hire as independent contractors and freelancers (1099 employees).
Form W-9 contains the name, address, and Social Security number or tax identification number (TIN) of a contractor. This form is not submitted to the IRS by either party, but returned to the hiring party by the contractor.
If you are a Deel user, you will be taken through the simplified flow, but the Form will match the official one.
