PEO stands for Professional Employer Organization. It’s a third-party entity that partners with Form W-9, also known as a Request for Taxpayer Identification Number and Certification, is a tax document that non-employer payers (think clients) use to collect key details from independent contractors or vendors they’ve paid during the tax year. In addition to name and address, form W-9 confirms the payee’s taxpayer identification number (TIN) so the payers can accurately report payments to the Internal Revenue Service (IRS), typically through form 1099.

Form W-9 is necessary because contractors and vendors do not have their taxes withheld by their employers as employees would. Instead, they must report income and pay taxes via their federal tax returns. If you do not submit a W-9 and your payers aren’t able to correctly report their payments, you may be subject to backup withholding up to 24% of your earnings.

Why do I need a W-9 form?

You need a W-9 form in a number of scenarios:

  • If you’re working as an independent contractor or freelancer, be ready to share your W-9 with the people or companies you work for. They require this to accurately demonstrate the payments they make to you.
  • When you earn certain types of income—like through real estate transactions, dividends, debt cancellation, etc.—you might be asked to provide a W-9 to certify your correct taxpayer ID information.
  • Keep a W-9 up to date and on file if you operate a sole proprietorship or business entity.

How to get a W-9 form

Form W-9 is available online at the official IRS website. The form itself is simple, but it’s important to fill out accurately, so be sure to consult the detailed instructions that begin at the bottom of page 1 of the form if you have any questions. And remember, you don’t file the W-9 with the IRS; you present it to any non-employers who will make payments to you.

Filling out the W-9 form: Navigating each section

There are seven key pieces of information that the W-9 collects. Let’s walk through each one:

  1. Name: This field is for the individual or business owner’s name. Ensure your name matches the one linked with your taxpayer ID number to prevent any discrepancies.
  2. Business Name (if applicable): If you’re operating under a business name or disregarded entity, add it here.
  3. Business Type: If you have formed a business entity, select the correct type here. If you are an individual, you can also select that option.
  4. Exemptions: Enter your exempt payee code if you are exempt from backup withholding for a reason like being exempt from FATCA reporting. Consult pages 3 and 4 of the form for the codes and who they apply to. Note that exemptions do not typically apply to individuals.
  5. Address: If you have a home address as well as a business address, it may be easiest to use the same street address you will use on your tax return. That way your Form 1040 can easily be matched to any issued 1099s.
  6. Taxpayer Identification Number (TIN): For most individuals this would be their Social Security Number (SSN), or put your Employer Identification Number (EIN) if you operate a business.
  7. Certification: Your signature asserts under penalty of perjury that the info you have provided is true. Double check your information for accuracy before you complete this step.

Common W-9 pitfalls to avoid

Even with the seemingly straightforward nature of the form, there are some pitfalls you should steer clear of:

  • Inconsistencies: Whether it’s your name or TIN, consistency across forms is key. A difference here or there can cause complications.
  • Falsehoods: The purpose of the form is to ensure that income is being accurately attributed and reported, so being economical with the truth on your W-9 can lead to a world of hurt (read: penalties) should the IRS come calling.

With a little care, form W-9 can ensure that your taxes are in order and that your earnings are safe from backup withholding. Check out form W-9 itself for even more in depth guidance.
