Reaching out to the community is essential to Caplin & Drysdale's core values of Excellence, Scholarship, Community, and Family. Therefore, to honor the communities in which Caplin & Drysdale maintains its offices – Washington, D.C., and New York City – the firm launched "Caplin Cares for a Cause," a charitable concern that donates funds and volunteer time to charities and entities that serve these communities. Throughout the year, lawyers and support staff take part in charities, including:
- Safe Shores - The DC Children's Advocacy Center, dedicated to supporting and working with child victims of sexual and physical abuse. Safe Shores coordinates a multidisciplinary team approach to abuse by handling everything from forensic services to family advocacy.
- American Bar Association Tax Section's Pro Bono Committee offers pro bono resources for the underserved.
- DC Employment Justice Center's Workers' Rights Clinic secures, protects, and promotes workplace justice in the DC metropolitan area.
- DC-Earned Income Tax Credit Campaign is a citywide, cross-sector initiative that educates the public about income tax benefits that promote greater economic security.
- New York University School of Law Tax Clinic operates as a free clinic for low-income taxpayers in the New York metropolitan area seeking assistance in cases docketed for trial in the U.S. Tax Court and certain related administrative proceedings before the Internal Revenue Service.
- Professional Tax Advisory Council for American Citizens Abroad, a nonprofit, non-partisan volunteer association whose mission includes acting as a voice for Americans living overseas.
