How to interpret these records

Listed in the BMF does not mean currently eligible for tax-deductible contributions. The BMF, Publication 78, revocation list and determination letters answer different questions. The IRS may update sources at different times. Always review the official IRS record before making a compliance or donation-deductibility decision.

Coming next: scheduled public-data ingestion, provenance and freshness tracking, revocation cross-checking, and state registry connectors. These are not yet active.
