Sustainable Flatbush is fiscally sponsored by the Open Space Institute, Inc., based in New York City, as part of its Citizen Action Program. Therefore, all your donations will go to OSI to fund our projects. Your donations will be accepted by OSI on our behalf, and are fully tax-deductible.

The Open Space Institute, Inc. is a tax-exempt public charity under Section 501(c)(3) and 509(a)(1) of the U.S. Internal Revenue Code. All contributions to the Open Space Institute, Inc. are tax-deductible to the fullest extent of the law. A copy of their latest financial report may be obtained by writing to OSI or the New York Department of State, Office of Charities Registration, The Capitol, Albany, NY 12231

Fiscal Sponsorship is a financial and legal system by which a legally recognized 501(c)(3) non-profit (such as the Open Space Institute) provides limited financial and legal oversight for a project initiated independently by a group. That “project” might be a one-time project or an organization that does not have its own 501(c)(3) status. Once sponsored in this way, the project is eligible to solicit and receive grants and tax-deductible contributions that are normally available only to 501(c)(3) organizations.
