Internal Revenue Service, Exempt Organizations Business Master File
Source: Internal Revenue Service, Exempt Organizations Business Master File Extract (EO BMF); filtered and reformatted by CorporateDB.
- Changes
- Selected fields are reformatted into CorporateDB's schema and statuses are mapped to its status vocabulary. In-care-of names and sort names are never collected, and the street address is left out wherever the IRS lists an in-care-of name, because it is usually that person's address. Trusts, partnerships, section 4947 trusts and organizations in subsections 82 and 00 are withheld.
- Dates
- The IRS replaces the extract monthly under the same file names, so the edition date is the latest Last-Modified date of its four regional files; CorporateDB reads them twice a month. Ruling dates and tax periods are the IRS's own.
