What Is Palantir's Contract With the IRS?

Not affiliated with Palantir Technologies Inc. This is a developing, contested story — we've laid out what's documented on each side. Sources are cited throughout.

Since 2018, the IRS's Criminal Investigation division has used a Palantir platform called Lead and Case Analytics (LCA) — built on Palantir's Gotham and Foundry products — to analyze financial records in pursuit of tax fraud and money-laundering cases. Public records show the IRS has paid Palantir over $130 million for this work since 2018 — a figure independently reported across multiple outlets, including The Intercept, TechCrunch, and Tax Notes, all citing records obtained by the watchdog group American Oversight. A separate, single-sourced figure from that same February 2026 Tax Notes report, citing USASpending.gov data, puts Palantir's total IRS payments since 2018 at over $180 million across 26 contracts — a broader number than the $130 million LCA-specific figure, and one we haven't yet found independently corroborated elsewhere, so it's presented here with that caveat rather than the same confidence as the $130 million figure. In 2026, Palantir's federal footprint expanded further, drawing new scrutiny from lawmakers, privacy advocates, and journalists.

What the LCA platform reportedly does

According to contract documents reviewed by The Intercept, the LCA platform lets IRS investigators "quickly search and visualize connections from millions of records with thousands of links" across databases maintained by the IRS and other federal agencies. Reported data sources plugged into the system include individual tax returns, bank statements, Affordable Care Act data, Treasury's FinCEN financial-crimes data, and cryptocurrency transaction data covering Bitcoin, Ethereum, Litecoin, and Ripple. A 2024 IRS privacy impact assessment, cited by multiple outlets, describes the platform's purpose as helping investigators find and map connections across disparate data sets in order to generate leads, identify schemes, and support tax-fraud and money-laundering investigations.

The broader 2025–2026 expansion

Beyond the LCA contract, reporting has documented a wider expansion of Palantir's federal government work during this period:

A New York Times report, cited by FedScoop, described Palantir in early-to-mid 2025 discussing potential technology sales with both the IRS and the Social Security Administration, alongside a reported $795 million Department of Defense contract and $113 million in other new or additional federal contract funding.
Wired reported Palantir participated in a "DOGE" (Department of Government Efficiency) initiative effort to help build a "mega API" allowing broader access to IRS records.
In September 2025, the Treasury Department announced a contract with Palantir to build a "unified API layer" — it's not publicly confirmed whether this is directly connected to the earlier DOGE-linked effort.

The case made against this arrangement

American Oversight, the nonprofit watchdog that obtained the underlying contract records via public-records requests, has been the primary source surfacing these details; its director, Chioma Chukwu, has publicly raised concern about consolidating highly sensitive personal financial data into a single platform operated by a private company.
Sen. Ron Wyden told The Hill he remains unconvinced Palantir is a trustworthy contractor, citing privacy problems, a lack of transparency, and what he described as "virtually no accountability" for the scale of data access involved.
Rep. Alexandria Ocasio-Cortez and other House Democrats sent a formal letter to Palantir CEO Alex Karp arguing that a searchable "mega-database" spanning tax returns and other sensitive data, potentially shared across agencies, likely violates federal privacy laws, including the Privacy Act.
Civil-liberties groups have filed suit seeking release of additional internal documents about the scope of the IRS relationship.

Palantir's response

In responses to congressional inquiries from Wyden and Ocasio-Cortez, Palantir has stated that it does not itself "control data" — emphasizing that the underlying government databases remain owned and operated by the respective federal agencies, with Palantir providing the software layer rather than holding the data independently. Neither Palantir nor the IRS provided additional comment when contacted by TechCrunch for its original report on the story.

What's still unresolved

As of this writing, the full extent of how data flows between agencies via Palantir's platforms — and whether the "unified API layer" work connects agencies' data in ways current privacy law anticipated — has not been fully confirmed publicly. Ongoing congressional requests and watchdog litigation may surface further detail.
