Eligible nonprofits often work with the Internal Revenue Service (IRS) on becoming a tax-exempt organization (a "501(c)(3)" for most nonprofits).

When nonprofits have employees or contractors, information from the Department of Labor is equally important.
The links here are commonly needed ones for nonprofit organizations. We hope to bring you more in the future. In the meantime, if you have specific questions related to what you find, please contact the relevant federal agency.
