Charities known as 501(c)(3) organizations are the most common type of IRS-recognized nonprofit. They’re exempt from taxes if they’re created exclusively for religious, charitable, scientific, testing for public safety, literary, educational, or other specified reasons, and if they meet certain other requirements.
While charities have existed in the United States since the Colonial era, modern nonprofits have been shaped by three major laws:
- The Wilson-Gorman Tariff Act of 1894, which required tax-exempt organizations to operate for charitable purposes
- The Revenue Act of 1950, which imposed taxes on business income unrelated to a charity’s core mission
- The Tax Reform Act of 1969, which placed limits on the tax-exempt activities of private foundations.
