Frequently Asked Questions
Simple answers to common questions
Where does the data come from?
IRS Form 990-PF published in machine-readable format. The raw data files are released by the IRS on a rolling basis and hosted by Amazon Web Services.
Can profiles be edited or removed?
Grantmakers.io has no control over the information provided in the public dataset by the IRS. Any inquiries as to removing information should be made directly with the IRS.
Why can't I find a foundation?
It's likely they either do not file their taxes electronically or they do not file Form 990-PF. Only private foundations that file electronically in the U.S. are shown on Grantmakers.io.
Do you make any changes to the data?
All data found on Grantmakers.io is presented exactly as found in the tax filings, with the exception of two minor formatting changes to improve readability. Details...
- City names are converted from UPPERCASE to Titlecase as needed.
- An 'N/A' label is added to missing or omitted fields in foreign address listings (e.g. if the state field is omitted, Grantmakers.io shows the 'N/A' label).
Do you exclude any data?
Only to stay within the free tier limits of our search partner. Generally speaking, this affects only older grants e.g. tax years 2009 and 2010. Details...
- Grant listings for 2009-2011 tax years are excluded from the searchable database.
- Grant listings for Bank of America Charitable Foundation are limited to tax years 2016 and later.
- Profiles based on tax years 2009-2011 only show the 50 largest grants.
Why is Grantmakers.io free?
The better question is why should it cost anything? The source data is published for free by the IRS. The site is hosted for free by Github Pages. The search is provided for free by Algolia. There is virtually no cost in hosting and maintaining this site.
Does open source mean I can copy this site?
Yes, and I hope you do! All source code and content is published on Github and liberally licensed for open use with the following exceptions: 1) I reserve all rights to the Grantmakers.io brand and logo, and 2) all third party logos and brands are property of their respective owners. In short, don't use any logos.
