Business Master File

Newly listed organizations

An organization is newly listed when its EIN is in the current EO BMF regional files and was absent from the prior slim index. A ruling year is not the same thing: it is the month and year on the determination letter, and many of those letters are old.

No prior slim index was available. Organizations newly added to the BMF, field changes, and Publication 78 additions or removals are not computed on this run. Those counts are not zero; they are not available yet.

Ruling year on the current BMF

This is the ruling-date year already on the file. It is not a count of organizations added this month.
