IRS Publication 5709 – IRS Forms, Instructions, Pubs 2026 – In an era where data breaches are increasingly common, protecting sensitive client information is crucial for tax professionals and businesses alike. IRS Publication 5709 serves as a vital resource, offering step-by-step guidance on developing a Written Information Security Plan (WISP) to ensure data safety. This publication, revised as of May 2024, emphasizes the legal requirements under federal law and provides practical tools for compliance. Whether you’re a solo tax preparer or part of a larger firm, understanding and implementing a WISP can protect your clients, your business, and help mitigate risks from cyber threats or physical disasters.
What is IRS Publication 5709?
IRS Publication 5709, titled “How to Create a Written Information Security Plan for Data Safety,” is a concise flyer designed to help tax professionals craft a robust data security strategy. It complements more detailed resources like Publication 5708, which includes a full WISP template, but focuses on the essentials for smaller practices. Enforced by the Federal Trade Commission (FTC) under the Gramm-Leach-Bliley Act (GLBA), a WISP is mandatory for all professional tax preparers to safeguard client data against theft, loss, or unauthorized access. The publication highlights the need for ongoing updates to the plan, treating it as an “evergreen” document that evolves with your business.
This guide is particularly relevant in 2026, as data security incidents continue to rise, prompting the IRS and Security Summit partners to urge professionals to review and strengthen their protocols.
Why is a Written Information Security Plan (WISP) Important?
A WISP isn’t just a regulatory checkbox—it’s a blueprint for protecting your business and clients from data breaches, identity theft, and operational disruptions. Federal law requires it, and failure to comply can result in penalties from the FTC. Key benefits include:
- Risk Identification and Mitigation: Helps assess vulnerabilities in employee training, information systems, and system failure management.
- Incident Response: Provides actions for events like data theft, fires, floods, or cyberattacks, including reporting to the IRS Stakeholder Liaison.
- Client Trust and Business Continuity: Demonstrates commitment to data safety, reducing liability and aiding recovery from disasters.
Without a WISP, tax pros risk severe consequences, including financial losses and reputational damage.
Steps to Create a WISP According to IRS Publication 5709
Publication 5709 outlines a straightforward process to develop a WISP tailored to your firm’s size, complexity, and data sensitivity. Here’s a breakdown of the key steps:
- Designate a Coordinator: Appoint one or more employees to oversee the information security program.
- Identify and Assess Risks: Evaluate potential threats to client data in areas like employee management, information systems (including networks and software), and system failures.
- Design and Implement Safeguards: Create policies for physical, technical, and administrative protections, then monitor and test them regularly.
- Select Reliable Service Providers: Ensure vendors maintain appropriate security measures and include this in contracts.
- Evaluate and Update: Review the plan periodically, especially after business changes or security incidents, to keep it current.
Additionally, incorporate a data theft response plan, referencing the FTC’s Data Breach Response Guide for post-incident actions.
Key Elements of a Strong WISP
Based on Publication 5709, a effective WISP should cover three core areas:
- Employee Management and Training: Educate staff on security protocols to prevent internal breaches.
- Information Systems: Secure networks, software, and hardware against external threats.
- Detecting and Managing Failures: Establish procedures for identifying issues and responding to incidents like data loss.
Include practical elements like offsite storage of the plan for disaster recovery and make it accessible in formats like PDF or Word for easy reference.
