Whether you need to complete a W-9, or any other version of IRS Form W-9, TaxZerone makes the process simple, secure, and ease. If you are wondering what is a W-9, what is a W-9 form used for, or how to fill out a W-9 form, this guide will help you understand everything you need to know.
What Is W-9?
A W-9 tax form (Request for Taxpayer Identification Number and Certification) is an IRS document used by businesses to collect taxpayer information from contractors, freelancers, vendors, and other nonemployees. The information provided on Form W-9 is typically used to prepare information returns such as 1099 forms.
TaxZerone makes it easy to request, complete, and securely manage Form W-9 online. Instead of downloading a fillable W-9 businesses and recipients can complete the entire process digitally through TaxZerone and ZeroneVault.
TaxZerone offers Form W-9 for free, allowing businesses to request and recipients to complete a free W-9 form online at no additional cost. There is no need for manual downloads, printing, or paperwork.
What is a W-9 used for?
A W-9 is used to collect taxpayer information, such as name, address, and TIN (SSN/EIN), so businesses can accurately report payments to the IRS and prepare forms like 1099 forms.
- Collecting recipient’s information: The form gathers a recipient’s or business’s name, address, and Taxpayer Identification Number (either a Social Security Number or Employer Identification Number).
- Preparing 1099 forms: This is the primary purpose. When a business pays a contractor $600 or more in a year, it’s required to file a 1099-NEC (or other 1099 variant) with the IRS. The W-9 provides all the details needed to do that accurately.
- Backup withholding: If a payee doesn’t provide a valid W-9, the payer may be required to withhold a flat 24% of payments for federal taxes — known as backup withholding. A completed W-9 certifies that the payee is exempt from this.
- Verifying tax status: The form also indicates the payee’s federal tax classification (sole proprietor, LLC, S Corp, etc.), which determines how their income is reported.
