Updated:
April 7, 2025

When your nonprofit organization works with independent contractors or provides services to other businesses, understanding Form W-9 becomes essential for proper tax compliance. This is a critical tax form that connects to your federal income tax responsibilities, so mastering the W-9 process helps maintain your tax-exempt status while fulfilling IRS requirements.

If you want to navigate tax season with confidence, look no further. The nonprofit tax services at SSL Associates can help organizations in Chicagoland and across the country ensure their W-9 forms and tax filings are accurate and compliant.

    What Is Form W-9?

    The IRS Form W-9, officially titled "Request for Taxpayer Identification Number and Certification," is a fundamental tax document for collecting information from contractors. This simple form helps organizations gather the correct taxpayer identification number and other essential details needed for tax reporting.

    Organizations complete the form in its entirety, while contractors complete only the first page; the rest contains instructions and notices explaining backup withholding requirements and other IRS code sections. The primary purpose of Form W-9 is to provide the needed information for completing Form 1099, which reports miscellaneous income and non-employee compensation to the Internal Revenue Service.

    When Do Nonprofits Need W-9s?

    Your organization will typically file W-9s in two different situations.

    Obtaining W-9s from Contractors

    When your nonprofit hires independent contractors — like consultants, freelancers, or service providers — you'll need their tax information. Instead of completing a W-9 yourself, you'll ask your contractors to fill one out.

    You should request a W-9 when the service provider:

    • Isn't your employee
    • Is working as an individual, partnership, or through another business entity
    • Will deliver services related to your organization's operations
    • Will be paid $600 or more during the calendar year

    Smart nonprofit managers collect W-9s at the beginning of contractor relationships rather than waiting until tax season approaches. For ongoing partnerships, you can keep the same W-9 on file for multiple years, unless the contractor notifies you of changes to their information.

    Providing Your Nonprofit's W-9

    Your nonprofit may also find itself on the other side of this equation. If another organization pays your nonprofit for services — perhaps for training workshops, consulting, or program implementation — they'll likely request that you complete a W-9. This helps them properly report payments made to your organization.

    How Does a Nonprofit Exempt Organization Fill Out a W-9?

    If you need to complete a W-9 for your organization, follow these seven straightforward steps.

    How to File Form W-9 for Nonprofits

    1. Put Your Legal and Common Names

    Start by entering your organization's legal name in Box 1. This should match exactly what appears on your incorporation documents and IRS filings. If your nonprofit operates under a different name (sometimes called a "doing business as" or DBA name), include that in Box 2.

    For instance, if your formal name is "Metropolitan Youth Development Coalition" but everyone knows you as "Metro Youth," you'd put the full legal name in Box 1 and the shortened version in Box 2.

    2. Indicate Your Tax Type

    In Box 3, your nonprofit must specify its federal tax classification from the following options:

    • Individual/sole proprietor
    • C corporation
    • S corporation
    • Partnership
    • Trustee/estate
    • Limited liability company
    • Other

    3. Check the Backup Withholding Box

    Box 4, the exempt payee code, relates to backup withholding exemptions. Most nonprofit organizations will leave this box empty, as it primarily applies to specific financial transactions like dividend payments or broker dealings. However, it's worth reviewing the exemption criteria in the form instructions to confirm this applies to your situation.

    4. Include Your Organization's Mailing Address

    Use Boxes 5 and 6 to indicate where the requester should send your 1099 form. Enter your organization's current mailing address, which can be a physical location or a P.O. box where you regularly collect mail.

    5. Add Requester Information (Optional)

    While optional, recording the requester's information can help you track who has your tax details. This is especially helpful for nonprofits that work with multiple partners and complete several W-9s each year.

    6. Include Account Numbers (If Requested)

    Some organizations use internal reference numbers to track their contractors. If the requester asks you to include a specific account number in Box 7, add it here. Otherwise, you can leave this section blank.

    7. Provide Your Taxpayer Identification Number (TIN)

    Finally, enter your organization's TIN in the appropriate section. Unlike individuals who use Social Security numbers, organizations use TINs for tax identification (tax ID).

    If your nonprofit has recently applied for a TIN but hasn't received it yet, write "applied for" in this field. You'll then need to provide the actual number within 60 days of submitting the form.

    What to Do After You Submit Your Nonprofit's W-9

    After completing your W-9, return it to the requesting organization. They'll use this information to prepare your 1099, which they should send to your nonprofit by January 31 of the following year.

    If you're collecting W-9s from contractors, your responsibility should instead focus on preparing 1099 forms for them. You'll combine information from their W-9s with your payment records to complete these forms accurately.

    When it comes to storage, all W-9 documents should be housed in a secure location, ideally in your accounting system or a protected digital environment. Maintain these records throughout your relationship with the contractor and for at least four years after issuing their final 1099. Make sure your organization's record retention policy addresses these documents specifically.

    While Form W-9 isn't as complex as some tax forms, accuracy is always important. Even small errors can lead to misreporting, potential penalties, or payment delays. If you’re hesitant about any part of the form, consult with a nonprofit financial professional like SSL Associates rather than guessing. This will save you time and stress in the long run.
