Form W-9 for a nonprofit or tax-exempt organization
Tax-exempt does not mean form-exempt. A 501(c)(3) still supplies a W-9, and it has an exempt payee code of its own to enter. What it does not have is a Line 3a box that says "nonprofit".
Name, box, number, and what gets reported
- Line 1
- The organization’s legal name as shown in its IRS determination letter
- Line 2
- Any name it operates or fundraises under
- Line 3a
- Other, with a description; or C corporation if incorporated and the requester prefers it
- Line 4
- Exempt payee code
1 - Part I
- The organization’s EIN
- Annual return
- Form 990, 990-EZ or 990-N
Exemption under section 501(a) means the organization does not pay federal income tax on its exempt-function income. It says nothing whatever about information reporting. Those are two separate systems that happen to meet on one piece of paper, and the second one does not care about the first. When a foundation makes a grant, a company pays a sponsorship fee, or a bank pays interest on the organization’s reserves, the payer needs a certified TIN, so it asks for a W-9. The request is routine, and it is not a challenge to your status. Declining it moves the organization into the uncertified column, where 24% of the next payment can be held back.
This is the part that stops treasurers and new board members. No box is marked "nonprofit" or "501(c)(3)". Most exempt organizations check Other and write a short description on the line, exactly as the IRS instructions contemplate.
What to put on each line
A only if the requester needs it for an account held outside the United States.Why exempt payee code 1 matters
Exempt payee code 1 covers an organization exempt from tax under section 501(a), any IRA, and a 403(b)(7) custodial account meeting the requirements of section 401(f)(2). Entering it tells the payer you are exempt from backup withholding, and that matters most on investment income, because without the code a bank may withhold 24% of the interest paid to your reserve account. On a large reserve that is real money, gone for the better part of a year, and recovering it means paperwork nobody budgeted for. Write the 1 in.
Do not staple your determination letter to the W-9; the form does not ask for it. Keep a PDF on hand anyway, because grant-makers and larger corporate donors routinely request it separately as part of vendor onboarding or due diligence.
What still gets reported to a nonprofit
Grants, fees, sponsorships and bank interest all arrive at an exempt organization, and they are not treated alike. The common ones usually land like this.
| Payment | Typical treatment |
|---|---|
| A grant from a private foundation | Generally not reported on a 1099 to an exempt payee; the foundation reports it on its own Form 990-PF |
| A corporate sponsorship fee | May be reportable, and may be unrelated business taxable income depending on what the sponsor receives |
| Payment for services your organization provided | Reportable on 1099-NEC unless an exception applies |
| Bank interest on reserves | Exempt from backup withholding with code 1; may still appear on a 1099-INT |
| A donation from an individual | Not a reportable payment. No W-9 needed |
| Government grant | Reported by the agency under its own rules |
Unrelated business income, employment taxes on staff wages, and some excise taxes all remain payable. And an organization that files no Form 990 for three consecutive years has its exemption automatically revoked, at which point code 1 no longer applies and every W-9 sitting in a funder’s vendor file is wrong.
When the nonprofit is the payer
Medical and health care payments are one of the few categories reportable even to a corporation: detail here.
Nonprofits collect far more W-9s than they issue. If your organization pays contractors, speakers, performers, honoraria recipients, or a landlord, you carry the same obligations as any other business: collect a W-9 before you pay, file 1099s where the $2,000 threshold is met by the deadline for that form, and withhold 24% where you hold no valid certification. A church treasurer’s version of the same job, honoraria and all, is at the church as the payer. Small organizations tend to discover this in January, when a volunteer treasurer starts hunting for the address of a workshop leader paid in cash eight months earlier. Collect the form up front and that January disappears.
- How to request a W-9, with wording and timing
- If a speaker or contractor refuses
- TIN matching before filing season
A payment to a guest speaker is compensation, whatever your minutes call it. If it reaches the reporting threshold it belongs on a 1099-NEC, and you need a W-9 before the check goes out. "It was only an honorarium" is not a reporting exception.
Mistakes to avoid
- Leaving Line 3a blank because no box says nonprofit. Check Other and write a description.
- Putting a treasurer’s SSN in Part I when the organization has an EIN of its own.
- Skipping exempt payee code 1, which can cost you 24% of your interest income.
- Putting a program or campaign name on Line 1 in place of the legal name in the determination letter.
- Assuming exemption means no W-9 is needed.
- Continuing to claim code 1 after automatic revocation for unfiled Form 990s.
Frequently asked questions
Should we check Other or C corporation on Line 3a?
Other with a description is the more accurate answer for an exempt organization. If a requester insists that its system only accepts a standard classification and you are incorporated, C corporation with exempt payee code 1 is a common practical compromise. Ask the requester which they prefer.
Do we need to send our determination letter with the W-9?
Not with the form. Keep it available for separate onboarding requests.
Are churches required to complete a W-9?
Churches are exempt without applying and often have no determination letter. If a payer asks for a W-9, complete it: Other on Line 3a with a description, exempt payee code 1, and the church EIN in Part I. The church case in full
What about a fiscally sponsored project?
The W-9 comes from the fiscal sponsor, in the sponsor’s name with the sponsor’s EIN, because the sponsor is the legal recipient of the funds. The project is not a separate taxpayer.
