Form 990

Tax Returns

CHRISTUS Stehlin Foundation for Cancer Research was organized in 1969 as a Texas non-profit corporation. It received original designation from the Internal Revenue Service as a tax-exempt public charity under Internal Revenue Code Section 501 (c)(3) in May 1969 (link to determination letter below).

Though exempt from federal taxation, the Foundation is required to file an information return annually with the Internal Revenue Service. The Foundation’s Forms 990 for recent years are available for viewing and download below. Past year’s returns are available for inspection at the Foundation office.
