CNN reported that Elon Musk's DOGE is building a master database for immigration enforcement with Palantir's assistance, going beyond existing ICE systems to identify people with civil immigration violations by integrating data across federal agencies.
Separately, DOGE engineers, Palantir representatives, and IRS staff collaborated to create a "mega API" providing centralized access to IRS records — including taxpayer details, tax returns, and employment data — with the ability to compare against other federal agency databases. Palantir's Foundry software serves as the centralized access point, enabling users to query and modify information while running AI models on sensitive taxpayer records. Project lead Sam Corcos (former SpaceX engineer) proposed halting $1.5 billion in existing IRS modernization to redirect resources.
The Data Integration Architecture
The DOGE-Palantir collaboration connects several previously separate data streams:
This creates precisely the kind of comprehensive cross-agency surveillance database that Congress banned when it defunded Total Information Awareness in 2003 — now reconstructed through private contractor Palantir, funded by DOGE, and deployed for immigration enforcement.
Legal Challenges
Eight members of Congress (including Sen. Ron Wyden, Rep. Alexandria Ocasio-Cortez) warned this creates a "surveillance nightmare" and potential "mega-database for targeting political enemies." The GAO is investigating DOGE's management of sensitive data. At least 15 federal lawsuits challenge DOGE's access to sensitive IRS and agency data. Career IRS employees raised concerns about access by personnel without legitimate need.
The data-sharing arrangement between IRS and ICE violates the legal principle that tax records must be kept separate from immigration enforcement — a protection designed so people can pay taxes without fear of deportation.
