A “mega API” could potentially allow someone with access to export all IRS data to the systems of their choosing, including private entities. If that person also had access to other interoperable datasets at separate government agencies, they could compare them against IRS data for their own purposes.
“Schematizing this data and understanding it would take years,” an IRS source tells WIRED. “Just even thinking through the data would take a long time, because these people have no experience, not only in government, but in the IRS or with taxes or anything else.” (“There is a lot of stuff that I don't know that I am learning now,” Corcos tells Ingraham in the Fox interview. “I know a lot about software systems, that's why I was brought in.”)
These systems have all gone through a tedious approval process to ensure the security of taxpayer data. Whatever may replace them would likely still need to be properly vetted, sources tell WIRED.
“It's basically an open door controlled by Musk for all American's most sensitive information with none of the rules that normally secure that data,” an IRS worker alleges to WIRED.
The data consolidation effort aligns with President Donald Trump's executive order from March 20, which directed agencies to eliminate information silos. While the order was purportedly aimed at fighting fraud and waste, it also could threaten privacy by consolidating personal data housed on different systems into a central repository, WIRED previously reported.
In a statement provided to WIRED on Saturday, a Treasury spokesperson said the department “is pleased to have gathered a team of long-time IRS engineers who have been identified as the most talented technical personnel. Through this coalition, they will streamline IRS systems to create the most efficient service for the American taxpayer. This week the team will be participating in the IRS Roadmapping Kickoff, a seminar of various strategy sessions, as they work diligently to create efficient systems. This new leadership and direction will maximize their capabilities and serve as the tech-enabled force multiplier that the IRS has needed for decades.”
Palantir, Sam Corcos, and Gavin Kliger did not immediately respond to requests for comment.
In February, a memo was drafted to provide Kliger with access to personal taxpayer data at the IRS, The Washington Post reported. Kliger was ultimately provided read-only access to anonymized tax data, similar to what academics use for research. Weeks later, Corcos arrived, demanding detailed taxpayer and vendor information as a means of combating fraud, according to the Post.
“The IRS has some pretty legacy infrastructure. It's actually very similar to what banks have been using. It's old mainframes running COBOL and Assembly and the challenge has been, how do we migrate that to a modern system?” Corcos told Ingraham in the same Fox News interview. Corcos said he plans to continue his work at IRS for a total of six months.
DOGE has already slashed and burned modernization projects at other agencies, replacing them with smaller teams and tighter timelines. At the Social Security Administration, DOGE representatives are planning to move all of the agency's data off of legacy programming languages like COBOL and into something like Java, WIRED reported last week.
