A counterintuitive trend is unfolding this tax season: CPA firms are adopting AI at record speed while taxpayer trust in AI is quietly declining.
According to the Invoice Home U.S. Tax Filing Report, only 37% of taxpayers would consider trusting AI over a human tax professional in 2026 — down 6 points from 43% last year. Every generation declined. Millennials fell from 54% to 50%. Gen Z from 49% to 46%.
At the same time, Wolters Kluwer reports AI adoption among accounting firms surged from 9% in 2024 to 41% in 2025.
The gap is widening, not closing.
This creates a specific problem for firms that don't communicate their AI use proactively. Clients who sense (but aren't told about) AI involvement fill the silence with their worst assumptions — hallucinations, errors, data breaches. The trust cost of a passive rollout is measurable.
The firms getting it right aren't hiding their AI use. They're framing it clearly in onboarding: AI handles document processing and routine compliance checks; humans make every judgment call. That single conversation eliminates most client anxiety.
The 59% of firms that still haven't formalized an AI strategy have a narrow window. By next tax season, clients will be asking directly. Having an answer ready — and a process to back it up — will be the differentiator.
