IRS 501(c)(3) Application
IRS Application for 501(c)(3)
The IRS 501(c)(3) application is completed upon approval of form 1023 or, in some qualified circumstances, form 1023-EZ.
The latter is simply an expedited version of the former.
The full form costs $600 to file, and the expedited costs $275.
The IRS estimates they may take over 100 hours to complete, so hiring a specialist is recommended.
