Data transparency
Where the data comes from
Imperigo is built from publicly available IRS Form 990 filings. We organize and present data to improve usability — we're not affiliated with the IRS.
Filings can contain inconsistencies or amendments. For high-stakes decisions, verify against the original filing.
FAQ
Quick answers
The common stuff, up front.
Is this official IRS data?
The source filings are IRS Form 990 submissions publicly available. Imperigo is independent and not affiliated with the IRS.
Why might numbers differ from other sites?
Different parsers can interpret filings differently, and organizations sometimes amend filings. If something matters, verify against the original.
Can I request a feature?
Absolutely — use Contact. If you include an EIN and what you're trying to do, it's much easier to act on quickly.
