IRS and AI: A Year of Transformation

by | Nov 26, 2025 | Articles

Accounting Career

In 2025, the IRS significantly expanded its use of artificial intelligence (AI), shifting from pilot projects to operational tools in audits, compliance, and taxpayer services.

This evolution was driven by the need to close the $688 billion tax gap, improve efficiency, and respond to government‑wide directives on AI governance

As we reach the end of 2025, the IRS’s growing reliance on artificial intelligence is becoming more apparent.

What began as cautious experimentation has evolved into a more structured, operational use of AI across several areas.

Key Developments in 2025

  • Audit Selection Modernization: AI now helps identify high‑risk returns more effectively, reducing wasted resources and improving enforcement.
  • Governance Framework: The IRS issued an Interim Policy for AI Governance, establishing principles for responsible AI use.
  • Strategic Pause in Tech Modernization: Certain modernization projects were paused to reassess how AI could be integrated.
  • Oversight Challenges: Staffing shifts limited the agency’s ability to monitor potential biases in algorithms, raising concerns about fairness.

Why the Shift Happened

  • Closing the Tax Gap: With an estimated $688 billion annual tax gap, the IRS is under pressure to make enforcement more effective.
  • Efficiency Gains: AI reduces reliance on manual review, helping the IRS process vast amounts of data more quickly.
  • Policy Direction: Federal directives in 2025 emphasized responsible AI adoption across agencies.
  • Public Scrutiny: Concerns about algorithmic bias prompted the IRS to balance innovation with accountability.

Next Steps for U.S. taxpayers

  1. Review filing accuracy — ensure returns are complete and consistent, as AI systems are designed to flag anomalies.
  2. Strengthen documentation — keep thorough records to support positions in case of audit.
  3. Monitor IRS guidance — stay updated on how AI is being applied to enforcement.
  4. Consult your advisor — discuss whether your filings may attract AI‑driven scrutiny.
  5. Plan for 2026 — anticipate that AI use will expand further, making compliance more data‑driven.

The key takeaways:

1. The IRS’s use of AI in 2025 reflects a turning point in tax administration.

2. While efficiency and enforcement are improving, oversight and fairness remain active concerns. Proactive compliance is the best defense in this new environment.

Gina and the folks at NZ US Tax Specialists were very quick to answer a question I had on the NZ tax treatment of US Military pensions, a fairly obscure area of tax law. They're great to work with.

Gina helped us prepare our US tax returns after we moved to NZ during a very busy time. We had no idea what was required as US citizens living abroad, but Gina was extremely helpful, knowledgeable, and professional. The work was affordable and well done. We had a great experience and hope to use NZ US Tax Specialists again.

If you're a US expat and need to file a US tax return, then look no further! Gina and her team at NZ US Tax Specialists does outstanding, professional work. I had to amend my US tax return, as I didn't know I had to file a form. Gina got that done, but they also found I'd made an error, and they fixed that for me as well, keeping me in good standing with the IRS. I'm definitely returning next year to get their assistance again.

I have been working with Gina since 2014, when I needed US Tax advice, being both a New Zealand and United States citizen. Over the eight years that we have been working together, I have found Gina to be extremely knowledgeable about the US tax system and the New Zealand IRD. She is quickly able to provide definitive answers to my US tax questions, via her extensive contacts in the US tax department.
Gina is always prompt in responding to my email and phone conversation questions and her professionalism has inspired my confidence in her many times over.
She has guided me through my annual tax return filing with integrity and honesty and I fully trust her to get the job done well each year.
