IRS Publication 4557, the FTC Safeguards Rule, and GLBA all expect you to control where client PII flows. PromptShielder masks SSNs, K-1 detail, and financial data in the browser before staff paste anything into ChatGPT.
Written for the firm partner.
IRS Publication 4557 and the amended FTC Safeguards Rule require a written information security plan (WISP) covering how client data is handled — including by third-party services. GLBA layers on additional obligations for anything that touches non-public personal information.
Under tax-season pressure, staff will do whatever is fastest: paste a full return into a public LLM to summarize a K-1, reconcile a schedule, or draft a client email. That single paste is a reportable breach under most WISPs. PromptShielder masks the return in the browser, so the model sees tokens and your obligations stay intact.
Staff paste 1040s, K-1s, and client emails into ChatGPT to move faster — every paste is a potential WISP breach.
The Safeguards Rule expects documented controls over PII sent to third parties. Public LLMs don't qualify.
One leaked return published in an AI training set ends a client relationship — and starts a state AG conversation.
