The National Taxonomy of Exempt Entities (NTEE) is a classification system developed by the National Center for Charitable Statistics. It categorizes tax-exempt organizations recognized by the IRS into groups based on their primary exempt purpose.
NTEE code U31 covers organizations focused on science & technology. This category falls within the broader Public Benefit sector, which includes civil rights, community improvement, philanthropy, and public policy organizations.
Data for these organizations comes from IRS Form 990, which tax-exempt organizations must file annually. Form 990 includes information about revenue, expenses, assets, executive compensation, program activities, and governance.
