The Near-Miss That Happens at Every Firm

A controller opens a tax memo her junior just drafted with AI. She's ready to send it to the client. She reads the first cited source. She searches the database. The citation doesn't exist. The AI made it up.

She stops, rewrites the section manually, flags the error in her notes and sends the corrected memo instead. Crisis averted. But the real question is harder: How many other firms didn't catch it in time?

KPMG's Report Had 40 Fake Citations

In October 2025, KPMG released a major report on AI and the future of business. The report sounded authoritative. It cited research, studies and data points throughout. Then someone checked the citations. 40 out of 45 were fabricated. The AI that wrote the report had made up sources.

Going Concern reported the story on June 16. GPTZero, a citation validation tool, found the hallucinations. KPMG removed the report from their website. But the damage was done. The report had already circulated to clients, partners, and competitors.

This is not a KPMG problem. It's an accounting problem. If KPMG didn't catch it, what prevents any firm from shipping hallucinated claims to clients?

What Does "Hallucination" Actually Mean?

Here's the plain truth about AI hallucination. AI learns from patterns in text. When you ask it a question, it predicts the next word, then the next word, building a sentence. This works great for writing and explaining. It fails when the pattern predicts a source or statistic that sounds real but doesn't exist.

The AI doesn't "lie" on purpose. It doesn't know the difference between a real citation and a fabricated one. It only knows that citations sound like this: "[Author Name], [Publication], [Date]." It generates text that matches that pattern. It feels confident. It sounds real. But it might be completely made up.

In accounting, this is a catastrophic failure. A tax memo with fabricated citations to IRS rulings is not just wrong. It's a liability. An audit memo with fake source citations might hide a control gap. A client letter citing research that doesn't exist damages trust and creates exposure.
