Duplicate EIN + Fiscal Year (NCCSKEY) in the Digitized Data (Technical Note)

Fifty-six EIN+fiscal years in the 1998 or 1999 GuideStar-NCCS database have more than one record. For two of these EINs, one of the records was an amended return.

For all of the duplicates, the ending month for the returns differed. This indicates that the organizations changed their fiscal years and probably filed returns for the partial year (e.g., June through Dec.).

NCCS has kept these records in its database so that users can include these non-duplicated finances in the totals for the fiscal year in question. However, for specific purposes, a researcher might wish to exclude these duplicates.
