Who Holds the Error When the Shortcut Fails
The liability gap in AI-assisted tax preparation is not a regulatory gray area — it is a structural feature of how these tools are sold. Deloitte's audit committee guidance and its broader AI-in-financial-services framing position AI as an organizational capability question, not an individual risk question. That framing is correct for the firms selling implementation. It is actively misleading for the filer or mid-level accountant who uses the output and signs the return.
The real AI story in tax and audit is impact, not adoption — and the impact is distributional. When an AI shortcut produces a filing error , the consequence attaches to the human who submitted it. The tool's vendor absorbs no penalty. That asymmetry is what practitioners resistant to AI adoption are actually describing when they say they don't trust it — not technophobia, but a correct reading of where accountability terminates.
