IRS Pub 4557 & the GLBA Safeguards Rule: Your Firm's Security Obligations

Every tax firm — not just outsourcers — is legally required to safeguard client data. What Pub 4557 and GLBA actually require, and how outsourcing fits inside a compliant WISP.

IRS Pub 4557 & the GLBA Safeguards Rule: Your Firm's Security Obligations

Many partners first meet IRS Publication 4557 while vetting an outsourcing provider — then realize the obligations it describes apply to their own firm, outsourcing or not.

What Pub 4557 Adds

Publication 4557 translates the rule into tax-practice terms: protect EFINs and PTINs, watch for identity-theft indicators, secure email and portals, control remote access, and train staff.

The Counterintuitive Truth

A specialized provider that lives inside these controls daily is often more compliant than the ad-hoc practices inside a busy small firm. Done right, outsourcing forces the security conversation your WISP needed anyway — and gives you audited answers to put in it.
