As a former Director (two years removed), Treasurer (two years), and Vice Chair of the PSF, I can shed some light on why their 2024 990 filing hasn’t happened yet. They aren’t due yet.
If you check their 2023 990 tax filing, they filed it on Nov. 15, 2024.
We can expect their 2024 990 tax filing by mid-November 2025.
Looking back, this trend appears consistent with the last 7 or 8 years of filings; however, the dates vary from the 15th to the 16th, depending on the year and whether it falls on a weekend.
