Data Quality or Limitations

Financial fields are provided by the IRS and are subject to verification. Where possible, NCCS recommends users use "NCCS Financial Info" fields in place of fields provided by the IRS, as these fields represent information cleaned and verified by NCCS (see data dictionaries for more info). NCCS also recommends users exclude all cases which are flagged "Out" on the field "OUTNCCS," as these represent organizations deemed out of scope by NCCS.

Usage Limitations

These files contain information for all registered tax-exempt organizations. Note that "registered" does not mean "active." BMF data files contain only a very limited selection of Form 990 data fields. For a larger selection of fields, refer to the NCCS Core files or IRS SOI Sample Files.
