IRS Aims to Upgrade Aging IT Systems

The IRS is on a mission to modernize IT systems that have been in place for more than 50 years—crucial for every tax season.

Internal documents sourced by the Federal News Network indicate that officials are focusing on the future of the Integrated Data Retrieval System (IDRS), a significant repository for taxpayer information.

This system enables IRS employees to access personal tax data and notify individuals directly when making inquiries. Taxpayers can also monitor the status of their federal tax refunds through IDRS.

Once this modernization initiative wraps up, the IRS believes it will enhance its employees’ ability to search through taxpayer records when they reach out to them.

This goal would be a significant achievement for agents who are currently hampered by some of the oldest IT systems in the federal government, struggling to secure necessary funding and staffing for the project.

However, it’s worth noting that this effort coincides with the IRS sharing sensitive info with the Department of Homeland Security’s Department of Government Efficiency (DOGE) and immigration officials.

A report from The New York Times noted that various agencies, including the DHS and IRS, are collaborating with tech firm Palantir to develop a massive interagency database. Furthermore, Wired reported that Palantir is also working with DOGE on a “Mega-API” for accessing IRS records.

In April, former acting IRS commissioner Melanie Krauss resigned, supporting the Trump administration’s initiatives to deport undocumented immigrants linked to the agency’s data-sharing agreement with DHS.

Officials from the Government Efficiency Bureau can access the IDR too. Currently, there are at least 15 ongoing federal lawsuits regarding the IRS and other agencies that challenge access to DOGE’s sensitive data.

Palantir’s global director for privacy and civil liberty, Courtney Bowman, denied that the company is involved in creating a master data list across various institutions. In a panel discussion on July 16, she clarified, “Palantir has not built a master list with federal agencies. There is no contract with DOGE for this kind of interagency information system.”

There’s still some uncertainty about the extent of the IRS’s progress in modernizing the IDRS or who will have access to the updated data. Both the Treasury Department and the IRS didn’t respond to requests for comment.

According to internal plans, the IRS intends to combine several systems, including those processing individual and business tax returns, into a single tax processing engine.

Updated IDRS systems are expected to facilitate “real-time tax processing nationwide,” allowing agents to “intercept or suppress false payments.”

Documents indicate that the IRS aims to phase out old mainframe systems once the migration is finalized, along with outdated applications where newer processes can replicate older outputs.

Former IRS commissioner Danny Werfel mentioned that IDRS modernization is progressing under his stewardship as part of the taxpayer 360 initiative.

Werfel also indicated that the modernization of IDRS remains a key priority, as reflected in the Trump administration’s budget request for 2026.

Internal documents reveal that the IRS is teaming up with various high-tech firms, such as Salesforce, Amazon Web Services, and Palantir, for this project.

Bowman noted that Palantir will assist the IRS with a “unified API” to help agents better serve taxpayers.

She explained, “The IRS operates on many different systems that currently don’t work well together. This causes customer service personnel to cycle through 10 to 15 different platforms to handle taxpayer inquiries, creating a lot of unnecessary hassle.”

Bowman asserted that Palantir’s role would be to help the IRS achieve what should already be manageable.

She added, “We think federal agencies ought to operate in a sophisticated digital environment, but currently, many still rely on outdated mainframe systems. Some modernization efforts have barely scratched the surface of what these agencies should ideally have access to.”

The IRS has strict controls over who can access the IDR. Their guidelines specify that “IDRS users are only allowed to access accounts necessary for their official duties.”

IRS regulations prevent employees from looking into their taxpayer accounts, or those of relatives, friends, or colleagues, especially if they have any personal or financial stake in those accounts.

During the AEI panel, Werfel emphasized that, as a default rule, sharing taxpayer data outside the IRS is prohibited under existing laws.

He commented, “While there are valid reasons for data aggregation, the process should involve public input, and it certainly shouldn’t take a decade to reach a decision.” He also highlighted the importance of transparency for understanding any associated risks.

Werfel noted, “If these risks are acknowledged, federal agencies can implement measures to address them. We’re moving so fast that we sometimes don’t grasp the full extent of these risks.”

Alex Gibbons, CEO of the Center for Democracy Technology, expressed worries about the unprecedented agreement the DHS holds with the IRS for accessing taxpayer records for immigration enforcement.

He stated, “We’re alarmed by recent trends under the Trump administration that permit new data sharing methods. We’ve built up laws and norms to protect people’s information for deliberate reasons, which shouldn’t be disregarded.”

In March, President Trump signed a Presidential Order directing agencies to eliminate “unnecessary barriers” to data sharing within the federal government.

Gibbons suggested that these decisions regarding data sharing were made without adequate consultation with privacy and civil liberty officials, which creates additional concerns.

Werfel did raise cybersecurity risks associated with widespread sharing of IRS data.

He remarked, “We have a skilled and resilient team tasked with protecting IRS data, but as we aggregate information, we must do so with careful consideration.”

The IDRS, established in 1973, continues to run on COBOL, presenting challenges since finding employees proficient in this outdated language is increasingly difficult.

The GAO reported in June 2018 that the IRS has been short about 20 developers needed for IDRS modernization, identifying at least 10 “single points of failure,” meaning only one employee could support certain features.

IRS officials informed GAO that employee burnout could cause delays in systems updates to reflect changes in tax legislation and might hinder the completion of critical IDRS project activities on schedule.

They noted that the IRS faces “significant risks due to reliance on legacy programming languages, outdated hardware, and a shortage of qualified personnel.”
