Place the nonprofit's official name and address in the proper places at the top of the W-9 form, not the name or address of the person filing out the form. Leave the space marked “DBA” blank unless the nonprofit is operating under a registered trade name.
Check the “C corporation” box in the section that asks for the entity type. All nonprofits are corporations. Alternatively, you could check the “Other” box and write in “nonprofit corporation.” Both methods are valid.
Indicate the type of income received in the next section. The applicable choices are “Other Income” and “Non-employee Compensation.” Choose “Other Income” if the payment expected will relate to something other than services rendered by the organization, such as lottery winnings. Otherwise, check “Non-employee Compensation.”
Provide the nonprofit's employer identification number, or EIN, in the “Taxpayer Identification Number” section. The EIN is the number the nonprofit uses to file its taxes, not the Social Security number of the person filing out the form.
Sign and date the certification section of the form. This section establishes that you are providing the requester with the correct taxpayer identification information to allow it to make an accurate report of payments to the IRS. Give the form to the entity requesting it.
