ProPublica Nonprofits (IRS 990)

No authpropublica-nonprofits

ProPublica Nonprofit Explorer — IRS tax-exempt organizations and their Form 990 filings. Search the IRS Business Master File of 501(c) exempt organizations by keyword (and narrow by state, NTEE major group, or 501(c) subsection), then pull any org's filed Form 990 financials (revenue, assets, compensation) year by year plus PDF-only older filings. Energy/O&G relevance: trade associations (American Petroleum Institute, AFPM) file as 501(c)(6); environmental NGOs and community/landowner groups file as 501(c)(3)/(4) — this is how you see their finances, leadership pay, and grants. No auth; GET-only.
