What is a fiscal sponsor?

Fiscal sponsors are tax-exempt, charitable ventures that, according to a June 2012 IRS report*, “have the ability to receive charitable contributions for specific projects, the infrastructure to ensure compliance with applicable federal and state laws and adequate internal controls to ensure that the funds will be used for the intended charitable purposes.” More information about fiscal sponsorship can be found on the National Network of Fiscal Sponsors web site:

Though fiscal sponsorship is sometimes described as a purely administrative relationship, at Earth Island it is a tool for providing support, building capacity, and creating community for grassroots environmental projects and activists.

* From the IRS Advisory Committee on Tax Exempt and Government Entities; Report of Recommendations June 6, 2012

How long does it take to become an EII project?

In general, it takes between three and four months for a project to submit a project application, go through the review process, get adopted by the Board of Directors, and complete orientation. Our process is quite a selective so not all projects that apply are adopted.

We consider new projects four times a year, and application deadlines June 1, September 1, December 1, and March 1. For more information about the project application process, please go to Become a Project section.

Do I need initial funding to qualify for sponsorship?

No. Earth Island Institute does not require confirmed funding to qualify for sponsorship. However, it will be the responsibility of EI sponsored projects to raise the funds needed to implement their programs and reach their goals.

If I'm already a 501(c)(3) organization, can I still apply?

Yes, we welcome applications from existing 501(c)(3) organizations. However, once you become an EI Project you must do all fundraising, income and expenses through Earth Island’s 501(c)(3), and your existing 501(c)(3) will have to be closed or made dormant.

Can I transfer to Earth Island from another fiscal sponsor

Yes, we will consider applications from projects wishing to transfer from another fiscal sponsor. Please make sure you indicate your current status in your application to Earth Island and we can discuss the specific steps in making this type of transition. This process requires cooperation and support of your current fiscal sponsor so we encourage you to discuss your plans with them as early as possible.

What if I need a sponsor immediately – before the next review cycle?

Under certain circumstances we will consider a project application outside of our normal review cycle; however, this is the exception rather than the rule. If you think that your project should be considered for expedited review, please submit a letter with your application describing the reason for your request. We will be consult with you and then make a decision.

What if I need temporary sponsorship?

Earth Island cannot provide short-term fiscal sponsorship. We’re looking for applicants who want to be part of our network and working with us on accomplishing program goals.
