Nonprofit Explorer — tax-exempt organizations
ProPublica (from IRS Form 990 filings)
In a RepVector build, this dataset exposes the nonprofit and community organisations operating in a territory.
Find any 501(c) organization by name or EIN with revenue and assets by year.
Search the Form 990 databaseWhat this dataset is
Tax-exempt organizations registered with the IRS, searchable by name or activity keyword, with location and NTEE activity classification. Identifies nonprofits, foundations and associations relevant to a topic, scoped to a state. It is published by ProPublica (from IRS Form 990 filings) and can be queried at state and nation level, refreshed updated as the irs releases filing data. Each row is an individual entity — an organisation, site or practitioner — so results can be filtered, routed and turned directly into a call list.
Why it is useful
- Finds referral partners and community entry points outside commercial registries.
- Reveals funded programmes that indicate where budget already exists.
Questions it helps answer
- Which community organisations here are natural referral partners?
- Where is grant-funded activity concentrated?
How different verticals use it
RepVector is vertical-agnostic: this dataset is selected by what your question asks for, not by industry. These are common ways teams put it to work.
Finds funded organisations that make natural referral or partner accounts.
Identifies foundations and systems with disclosed revenue and programmes.
Locates funders behind training and community programmes.
Segments nonprofit balance sheets for treasury and lending conversations.
How RepVector uses it
- You describe a market in plain language. The geography resolver turns the place you named into the exact identifiers this dataset needs — city to county to state, plus DMA where relevant — so a query at state runs without you knowing any codes.
- The planner selects Nonprofit Explorer — tax-exempt organizations only when your question matches what it actually reports. It is never included to pad a result.
- Returned rows are normalised into the shared metric layer, so figures from ProPublica (from IRS Form 990 filings) line up with every other source in the same dashboard instead of sitting in an isolated table.
- Quality checks score coverage and recency. If ProPublica (from IRS Form 990 filings) suppresses or omits a value for your geography, the gap is reported as a gap — nothing is estimated or filled in.
- The result renders as charts, KPIs and, where the rows are entities, prioritised targets you can export to PDF, Excel, CSV or JSON.
What it does not tell you
- Filings arrive annually, so organisational detail can be a year behind.
How it fits with the rest of the catalog
Nonprofit filings widen a call list beyond the obvious clinical or commercial targets. RepVector queries every selected dataset against the same resolved geography and time window, then normalises the results into one metric layer so they can be charted side by side. These datasets are the most common companions to Nonprofit Explorer — tax-exempt organizations:
Common questions
Is there a free IRS Form 990 database?
Yes. IRS filings are public, and RepVector's free 990 lookup searches them by organization name or EIN and returns revenue, expenses and assets by filing year.
How far back do filings go?
Most organizations have several years of digitised filings. Very small nonprofits filing the 990-N postcard report registration only, with no financial detail.
