Abstract:

Many private foundation data come from a single source, the information return, Form 990-PF. Forms 990-PF are available to the public for analysis and inspection via the internet. Additional statistics are created by the National Center for Charitable Statistics at the Urban Institute and are based on annual extracts from the IRS Returns Transaction File (RTF), which are provided to NCCS by IRS staff. A third resource is the Statistics of Income study of private foundations, which is based on a weighted annual sample of Forms 990-PF that are key-entered by IRS staff and reviewed for mathematical and reporting errors. However, the statistics derived from Forms 990-PF may vary widely, depending on the manner in which the data are collected. The paper will compare Form 990-PF data on the SOI sample file to those from the annual RTF extracts and make efforts to explain discrepancies. In addition, data from returns filed by a sample of large private foundations will be obtained from the internet and further compared to the other sources to evaluate the effects of IRS data entry and correction procedures on the various statistics.
