The U.S. Treasury Department awarded Palantir a Blanket Purchase Agreement to create a "unified API layer" supporting developer platforms, workflow automation, and data analytics for the IRS as part of IT modernization. The contract enables centralized access to IRS data through Palantir's Foundry platform.
The contract subsequently became the foundation for DOGE's far more aggressive "mega API" project, in which Palantir representatives, DOGE engineers, and IRS staff collaborated to create a system providing access to taxpayer details, tax returns, and employment data — with the ability to compare IRS records against other federal agency databases. Sam Corcos, a former SpaceX engineer leading the DOGE effort, proposed pausing $1.5 billion in existing IRS modernization projects to redirect resources.
Career IRS employees raised concerns that the system would make highly sensitive taxpayer data accessible to personnel without legitimate need. The Government Accountability Office launched an investigation into DOGE's management of sensitive data across departments. At least 15 federal lawsuits challenge DOGE's access to sensitive IRS and other agency data.
The Treasury contract represents a critical node in the emerging surveillance architecture: Palantir builds IRS data access → DOGE demands cross-agency data sharing → IRS taxpayer data flows to ICE via ImmigrationOS → immigration enforcement gains access to tax records that were legally segregated to protect taxpayers from exactly this kind of targeting.
