Example prompt: Can you check whether the nonprofit with EIN 13-1837418 is currently IRS tax-exempt, whether donations to it are deductible, and if it's ever had its status revoked?

## When to prefer this

Use this endpoint when you need authoritative, current IRS data on a specific US nonprofit's tax-exempt status and donation deductibility. Ideal for due diligence before charitable giving, grant processing, compliance checks, or verifying nonprofit legitimacy. Prefer over general web searches when you need structured, machine-readable IRS data including revocation history and Publication 78 eligibility codes.

## Known failure modes

- EIN not found in IRS records — organization may not exist or may not be registered as tax-exempt
- Invalid EIN format (must be 9 digits) — returns validation error
- Organization exists but has no Publication 78 listing — deductibility fields will be absent
- Network or upstream IRS data source unavailability — returns service error
- EIN belongs to a for-profit entity rather than a nonprofit — status will reflect non-exempt

## How this service works

Crisp authoritative IRS tax-exempt status for a US nonprofit by EIN: whether it is currently tax-exempt, listed in Publication 78 as able to receive deductible contributions with the eligibility code, whether its status was automatically revoked with the revocation and reinstatement dates, and its 501(c) subsection.

## Output

Returns whether the nonprofit is currently tax-exempt, its 501(c) subsection, whether it appears in IRS Publication 78 with deductibility eligibility code, and whether its status was automatically revoked along with revocation and reinstatement dates if applicable.
