OWASP Foundation

The OWASP Foundation
The OWASP Foundation was established on April 21, 2004 as a not-for-profit charitable organization in the United States to ensure the ongoing availability and support for our work at OWASP. OWASP is an international organization and the OWASP Foundation supports OWASP efforts around the world.

Tax Status: 501(c)(3) Not-For-Profit Organization
The OWASP Foundation is a U.S. recognized 501(c)(3) not-for-profit charitable organization. The OWASP Foundation received its formal recognition by the U.S. government of its 501(c)(3) status on December 10, 2004. This not-for-proft status allows contributors to deduct any donations made to the OWASP Foundation.

OWASP's U.S. Employer Identification Number (EIN) is: 20-0963503.

Tax Deductability of Payments to OWASP
OWASP membership fees, OWASP conferences fees, OWASP conference sponsorships, and OWASP banner ads are not considered tax-deductible donations due to the benefits the paying organization/individual receives.

Direct donations to OWASP are fully tax-deductible given OWASP's recognized U.S. not-for-profit status.
