IRS Publication 5461-D emphasizes the critical need for robust security measures to protect both clients and practices. Released as part of the IRS Security Summit’s ongoing efforts, this publication serves as a wake-up call for tax pros to reassess and strengthen their defenses against evolving threats. With the 2025 tax season behind us and 2026 approaching, staying compliant isn’t just best practice—it’s a legal requirement under federal law.
This article dives into the key aspects of IRS Publication 5461-D, including its purpose, recommendations, and how to implement them effectively. Whether you’re a solo practitioner or part of a larger firm, reviewing your security protocols can safeguard your business and maintain client trust.
What is IRS Publication 5461-D?
IRS Publication 5461-D, titled “Tax Professionals Should Review Their Security Protocols,” was revised in November 2022 and remains a cornerstone resource for the tax industry. Developed in collaboration with the IRS and Security Summit partners, it addresses the persistent threat of identity thieves targeting tax professionals. The document is concise, focusing on practical steps to enhance data security.
The publication is part of the broader “Protect Your Clients; Protect Yourself” campaign, which runs annually to raise awareness about data theft risks. According to IRS data, tax pros continue to face sophisticated scams, including phishing emails and phone frauds designed to steal client information. By urging a review of security measures, the IRS aims to reduce vulnerabilities and promote a culture of vigilance.
Key highlights from the publication include references to the “Taxes-Security-Together” Checklist, which outlines fundamental protections. It’s available in multiple languages, including Spanish and Chinese-Simplified, ensuring accessibility for diverse practitioners.
Why Tax Professionals Need to Review Security Protocols Now?
Identity theft in the tax sector isn’t slowing down. In 2025, the IRS Security Summit highlighted emerging threats like advanced phishing schemes and remote work vulnerabilities. Tax professionals often store sensitive data such as Social Security numbers, bank details, and financial records, making a single breach potentially devastating.
Failing to review protocols can lead to severe consequences, including FTC investigations, loss of e-file privileges, and reputational damage. The Gramm-Leach-Bliley Act and FTC Safeguards Rule mandate that all professional tax preparers maintain a Written Information Security Plan (WISP) to protect client data. Non-compliance isn’t an option—it’s enforceable by law.
Regular reviews help identify gaps, especially with the rise of remote work and cloud-based tax software. As of 2026, the IRS continues to emphasize that basic oversights, like weak passwords or unsecured networks, are common entry points for hackers.
Key Recommendations from IRS Publication 5461-D
The publication provides a straightforward checklist to bolster security. Here’s a breakdown of the main recommendations:
- Deploy Basic Security Measures: Install anti-virus software, firewalls, and ensure regular updates to defend against malware.
- Implement Multi-Factor Authentication (MFA): Protect tax software accounts with MFA to add an extra layer of verification beyond passwords. This is part of the “Security Six” protections promoted by the IRS.
- Use a Virtual Private Network (VPN): For remote work, a VPN encrypts data transmissions, preventing interception on public networks.
- Create a Written Data Security Plan: Required by federal law, this plan outlines how your practice handles, stores, and protects data. Use IRS Publication 5708 as a template for developing your WISP.
- Educate on Phishing and Scams: Recognize and avoid email or phone scams that trick users into revealing sensitive information.
- Develop Data Theft Recovery Plans: Have protocols in place for responding to breaches, including notifying clients and authorities promptly.
These steps align with broader IRS guidelines, such as those in Publication 4557, “Safeguarding Taxpayer Data,” which offers detailed implementation advice.
Legal Requirements and Compliance for Tax Pros
Under the FTC Safeguards Rule, tax professionals must implement comprehensive security programs. This includes risk assessments, employee training, and regular testing of safeguards. Violations can result in penalties and suspension from IRS programs.
The WISP is central to compliance. IRS Publication 5709 provides a step-by-step guide to creating one, tailored for tax and accounting practices. Additionally, Publication 5293 serves as a resource guide for data theft incidents, helping pros navigate recovery.
For 2026, the IRS recommends annual reviews of your WISP, especially with updates to multi-factor authentication standards and encryption requirements.
Best Practices and Additional Resources
Beyond the basics, consider these enhanced strategies:
- Encrypt Drives and Back Up Data: Use encryption for stored files and maintain secure backups to prevent data loss.
- Secure Data Transmission: Always use HTTPS for online interactions and avoid unsecured Wi-Fi.
- Employee Training: Conduct regular sessions on recognizing threats, as human error is a leading cause of breaches.

Implementing Security Protocols in Your Practice
Start by downloading IRS Publication 5461-D from the official IRS website and reviewing the “Taxes-Security-Together” Checklist. Assess your current setup: Do you have MFA enabled? Is your WISP up to date?
Next, use templates from Publication 5708 to draft or update your security plan. Test your systems regularly and document everything to demonstrate compliance.
If a breach occurs, refer to Publication 5293 for guidance on reporting to the IRS and affected parties.
