AI use in accounting firms is no longer new.
But the questions around client data are.
Most firms have focused on what AI produces.
Few have examined what AI receives.
Where the Issue Starts
When a staff member uses an AI tool to assist with client work, data moves.
It may be a client name. A financial figure. A tax document.
In many firms, this happens informally:
no defined list of what data AI tools can receive
no vendor review before tools are used with client files
no disclosure to clients that AI is being used
At first, this feels low-risk.
Over time, it creates exposure.
Why This Matters
According to CPA.com and AICPA risk-control guidance:
Entering data into a generative AI tool means sharing that data with the tool's owner.
Some vendors reserve the right to access, store, reuse, or train their models on firm-generated content — unless explicitly restricted by a signed agreement.
Most firms have not reviewed those terms.
Most staff members have never seen them.
This is not a technology problem.
It is a governance gap.
What Insurers Are Watching
Professional liability insurers covering CPA firms are paying attention.
Aon — which administers the AICPA Member Insurance Program — confirmed in April 2026 that there has yet to be major litigation against accounting firms related to AI usage.
But that window is closing.
McGowan Program Administrators, which underwrites coverage for thousands of CPA practices, now recommends:
AI disclosure language inserted in all engagement letters
An opt-out clause for clients opposed to AI use
A formal AI governance program to support both
These are not theoretical recommendations.
They are practical guidance from the insurers who will evaluate your firm if a claim arises.
The Hidden Risk
The issue is not that AI tools are unsafe.
It is that usage is outpacing structure.
Because without documented governance:
client data enters tools without firm oversight
vendor terms go unreviewed
disclosure to clients never happens
the firm cannot demonstrate what controls were in place
What This Leads To
Over time, firms face:
confidentiality exposure from undocumented AI tool use
insurer scrutiny without a governance program to reference
client trust issues when AI use is discovered rather than disclosed
Not because AI was used incorrectly.
Because no structure existed around how it was used.
Three Questions Every Firm Should Be Able To Answer
→ What happens to client data when your team uses an AI tool?
→ What happens when the AI output is wrong — and who is accountable?
→ Have clients been told AI is being used in their engagement?
If these questions don't have documented answers — the governance gap is open.

AI doesn't create liability in firms because of what it produces.
It creates exposure where governance is undefined.
