  • The agency spent at least $60 million on AI in 2024
  • Says it’s committed to taxpayer privacy, transparency

IRS spending on artificial intelligence rose by over 700% in the last half-decade as it hones the use of machine learning to identify tax cheats and improve taxpayer communication, according to Bloomberg Government contracting data.

Agency spending of at least $60 million in fiscal 2024 on AI and machine learning is expected to keep rising in coming years—an upshot of the agency tapping into billions provided in the 2022 tax-and-climate bill.

And though the IRS has provided some details on how it’s using the new transformative tech, lawmakers in Congress are keeping their attention focused on agency oversight.

“We just want to know how they’re using AI tools to improve the efficiency of the operation, improve customer service, and go after very rich, wealthy tax deadbeats,” said Sen. Chris Van Hollen (D-Md.), who chairs the Senate Appropriations subcommittee that determines IRS funding.

A government watchdog analysis requested by then-House Ways and Means Committee Oversight subcommittee ranking member Bill Pascrell (D-N.J.) into the IRS use of AI and its policies to ensure accountability and fairness is underway and expected in the summer of 2025.

IRS spending rose from at least $7.1 million in fiscal 2020 to at least $60 million in fiscal 2024, according to an analysis by Bloomberg Government of the market for artificial intelligence and machine learning contracting data.

Passing the ‘Smell Test’

The IRS has touted AI often, including in how it used the technology to select dozens of partnerships for audit last year and how it is improving customer service at call centers.

It turned to voice and chatbots to help taxpayers avoid long wait times and get their basic questions answered quickly. The average call wait time for all phone lines was about 8 minutes for the 2024 filing season, a dramatic improvement compared to years prior to receiving resources from the 2022 tax-and-climate law known as the Inflation Reduction Act.

“When I was still there, the IRS was very strict to make sure it’s used properly at appropriate levels in the organization before going forward, with any sort of use of artificial intelligence—that it meets the smell test and that we are doing it for the right reasons,” said Darren Guillot, national director at alliant and former IRS commissioner of the Small Business/Self Employed Division.

But how IRS and other agencies look at AI is changing. The Biden administration recently provided new guidance on AI procurement throughout government.

The IRS in September released interim guidance on the agency’s privacy policy related to use of AI, in line with the requirements in executive orders and Treasury directives, the IRS said in a statement.

“The IRS is committed to protecting taxpayers’ privacy and ensuring transparency about how it uses artificial intelligence to improve our service to taxpayers, combat fraud and identity theft, and support sound tax administration,” the agency said in a statement. It added that these public requirements ensure individuals can contest determinations they believe may have been made based on inaccurate information.

Agencies should start thinking about AI as any other investment, not only to understand its impacts and justify it, but to make sure it doesn’t conflict with or duplicate existing tech, said David Hinchman, a director in the Government Accountability Office’s information technology and cybersecurity team.

A GAO report in June found that the IRS has subpar documentation of its AI audit selection methods.

“Our work has shown that the federal government is very much in the beginning stages of its ‘AI journey’ and an important part of considering what AI means for the government will be to figure out the financial implications,” Hinchman said.

Holding the Checkbook

Beyond Ways and Means, Republican House lawmakers like Judiciary Chair Jim Jordan has requested information from the IRS for its AI use. And those holding the government’s purse strings recently tacked on briefing requests into spending bill reports to get a better handle on what the agency is doing with it.

The Democrat-controlled Senate’s proposed report accompanying the fiscal 2025 spending bill required agency officials to brief the committee within 180 days of the bill’s enactment. They wanted more details on IRS examination of the risks and opportunities associated with AI, along with potential implementation steps and other considerations like the risks of bias and the need for transparency.

The IRS caught heat from Democrats after a study found the agency’s automation to identify potential tax cheats flagged Black taxpayers at higher rates than non-Black filers. IRS Commissioner Danny Werfel cited the agency’s data and its automation processes as the culprit and promised a fix for the disparity.

A spending bill hasn’t yet been finalized. Lawmakers cleared a stopgap funding bill last month, punting a funding fight until after the November election.

IRS enforcement efforts—boosted by billions in funding from the 2022 tax-and-climate law—has been a political football for Congress, but there’s bipartisan support for AI in efforts to improve the taxpayer experience.

Rep. David Schweikert (R-Ariz.), who chairs the House Ways and Means oversight subcommittee, said he remains cautiously optimistic about IRS use of AI, even as the bills continue to rise.

“It’s not about the spending, it’s the quality of the adoption, and the rollout,” he said. “We have to deal with the reality that the technology is here.”

Guillot said he is hopeful that the IRS is able to more efficiently process the pipeline of ERC claims to get the intended financial help to well-meaning businesses.

Justin Elanjian of Stout Risius Ross LLC agreed that there has been a lack of transparency as well as inconsistency and inaction from the IRS regarding the processing of claims.

Better communication about the status of the backlog and wait times “would be helpful as businesses are continuing to evaluate their options for an unprocessed claim,” Elanjian said.

“Many taxpayers don’t have this luxury of waiting in perpetuity for these refunds to process,” Elanjian added.

However, fully alleviating the concerns of businesses that await refunds could still be challenging.

Instituting a boost in processing and more transparency regarding claim status “may prove to be too little, too late if ERC claim processing times are not significantly shortened in the near future,” according to Mary E. Wood of Meadows, Collier, Reed, Cousins, Crouch & Ungerman LLP.

“Unfortunately, the massive amount of perceived fraudulent ERC claims has severely undercut the IRS’s efficiency in processing and paying legitimate claims,” Wood said.
