About this data

Figures are aggregated from Riverstyx Foundation's IRS Form 990-PF electronic filings (1 filing on file, most recent tax year 2024). Totals reflect grants the foundation reported as paid, and can lag the current year because foundations file annually and often on extension. Source: IRS 990-PF e-file archive.
