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.
The IRS, 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.
Last Friday, DOGE suddenly placed around 50 IRS technologists on administrative leave. On Thursday, even more technologists were cut, including the director of cybersecurity architecture and implementation, deputy chief information security officer, and acting director of security risk management. IRS’s chief technology officer, Kaschit Pandya, is one of the few technology officials left at the agency, sources say.
DOGE originally expected the API project to take a year, multiple IRS sources say, but that timeline has shortened dramatically down to a few weeks. “That is not only not technically possible, that’s also not a reasonable idea, that will cripple the IRS,” an IRS employee source tells WIRED. “It will also potentially endanger filing season next year, because obviously all these other systems they’re pulling people away from are important.”
