What it reported for 2024

What these figures are, and what they are not

Each figure is what the organization reported on its own return, as the IRS published it. The IRS does not audit the return before publishing it.

A private foundation reports its assets twice. Book value is what it paid for them; fair market value is what they are worth now, and it is usually the larger of the two. Rankings on this site use book value, because that is the only measure a Form 990 and a Form 990-EZ also report, which keeps a foundation comparable with the charities beside it.

Wilczynski Foundation Inc reported paying William Keehn, Director, $96,000 for 2024. That is reportable compensation from the organization, from related organizations, and other compensation, as the organization reported all three. It is not a verified salary and not take-home pay.

What this page cannot show

Everything here is what the organization told the IRS about itself. The IRS publishes returns as filed and does not audit them first.
The figures describe the most recent year on record, which is usually one to two years behind, and not the organization’s current position.
Nothing here says whether the organization does its work well, or how it spends what it raises beyond the totals on the form.
