Welcome to the Commons!

Social Impact Commons is a community of fiscal sponsors, sponsored projects, funders, and other ally organizations interested in advancing equity and effectiveness in the nonprofit sector through fiscal sponsorship. Through our research, advocacy, tools, and direct services, membership in Fiscal Sponsorship Commons is your connection to information and expertise on fiscal sponsorship and nonprofit infrastructure sharing.  

Over the first quarter of 2026, we are transitioning to a new online platform, Fiscal Sponsorship Commons, that joins our resources with those of Fiscal Sponsor Hub under ONE membership.
