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. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.
Grants made
No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.
Grants received
No itemized grant names this organization as a recipient. Only grants over $5,000 are itemized, and only by filers of the full Form 990.
Related organizations
From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Other IRS files
Auto-Revocation List
Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.
Publication 78
Listed as of 13 October 2026, under deductibility SOUNK.
These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
What this page reflects
The registration facts above come from the IRS Business Master File published 13 October 2026 and read 26 October 2026, for every organization at once. Returns through tax year 2023, the newest we have parsed for this organization.
