Form 990 for tax year 2024

What the amendment changed

Compared with the latest return for 2024 , filed 26 March 2026. matched by us Only the return's totals, a 990-PF's accounting method and the names listed in Part VII (Part VIII on a 990-PF) are compared. We relate returns by organization, tax year and form, and order them by each return's own timestamp; the filer's own "amended return" checkbox is a separate fact.

Those are the same on the two returns, so the amendment changed something else.

As filed on the 2024 return. The filer continues this part on Schedule O, which is not shown here. A text marked withheld matched a screen for wording that may name a private individual, such as an honorific or "in memory of". Most of what it withholds names no one; it is withheld so that what does is never shown.

Listed in Part VII

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us.

Schedule J

Part I's answers as filed. A line not listed was left unanswered; on lines 1a and 3 that means the box was not checked.
