Cybercrime targeting professional services continues to rise, and CPA firms face more pressure to protect the financial data, tax records, and personal identifiers they manage every day. The FBI reports U.S. cybercrime losses reached $16.6 billion in 2024, a 33% year-over-year increase.
For your firm, that impact turns into operational disruption. One compromised mailbox or failed control can halt workflows, delay filings, and reduce audit readiness.
Attackers target firms with preventable weaknesses. Missing MFA, untested backups, and unsupported systems create easy entry points. These issues are common in environments where documentation falls behind actual practice or where too many unmonitored cloud apps create shadow IT.
These gaps make it harder to meet FTC Safeguards, IRS guidance, SOC 2, and state requirements. Outdated documentation and inconsistent controls create blind spots in data security and client information protection.
This article breaks down seven compliance mistakes firm owners, partners, and administrators encounter most often. It also shows how Tech Advisors strengthens compliance for CPA firms and supports broader accounting firm IT compliance through continuous monitoring, WISP management, and structured BCDR planning.
Key takeaways
- Reduce compliance failures caused by human error, outdated systems, and incomplete documentation.
- Align your firm with the FTC Safeguards Rule, SOC 2, HIPAA, and WISP frameworks that govern CPA firm security requirements.
- Maintain risk and maintain audit readiness through Tech Advisors’ proactive, continuously monitored compliance approach.
Why IT compliance is critical for CPA firms
Your CPA firm operates as a financial institution under the FTC Safeguards Rule and the Gramm-Leach-Bliley Act (GLBA), which sit at the center of compliance regulations for CPA firms. These regulations require you to protect client data, customer information, and financial statements by implementing documented data protection and security controls. HIPAA may also apply if your firm handles PHI for healthcare clients.
The IRS reinforces these obligations. The IRS “Protect your clients; protect yourself” (2025) guidance links GLBA and the Safeguards Rule to CPA workflows and outlines the internal controls required for audit readiness.
Suppose you store client data in cloud systems without documented access controls. In that case, you risk violating GLBA and creating unnecessary exposure to cyber threats and unauthorized access, an issue that cloud services for accounting firms help resolve through secure configuration and permission management.
Non-compliance damages your firm’s reputation, increases regulatory risk, and weakens long-term client trust. Strong IT compliance closes those gaps and prevents costly security failures.
The 7 most common IT compliance mistakes CPA firms make (and how to avoid them)
1. No written information security plan (WISP)
A written information security plan (WISP) explains how you protect sensitive information, manage controls, and perform risk assessments. Many firms still operate without a formal information security program, relying on outdated or informal documentation, even though compliance services for accounting firms can maintain and update WISP documentation year-round. Some firms rely on email threads as their ‘policy,’ creating significant compliance gaps.
Massachusetts regulation 201 CMR 17.00 requires any business that handles personal information of Massachusetts residents, including CPA firms, to maintain a written information security program that meets specific technical and administrative standards.
IRS Publication 4557 requires documented internal controls and a written data security plan for any firm that handles taxpayer information.
Tech Advisors maintains and updates your WISP throughout the year to keep it aligned with GLBA, state mandates, and your workflows.
2. Outdated or unverified backup procedures
Backups protect you only when they restore cleanly. Many CPA firms use cloud-based or on-premises backups, but never test them. A backup that is never tested will fail when you need it most, which is why data backup and disaster recovery for accounting firms include continuous verification and monitored restore testing. This creates risk during ransomware events, server failures, or cyberattacks and undermines your disaster recovery posture.
The ISACA State of Cybersecurity report highlights how staffing pressure often leads to untested backups and weak continuity programs.
Tech Advisors uses automated verification within its business continuity and disaster recovery (BCDR) routines to validate backups, reduce vulnerabilities, and keep your managed IT services resilient.
3. Weak access controls and poor password hygiene
Weak or inconsistent access controls expose your systems to unauthorized access and increase breach risk, especially during tax season when more users log in from multiple devices. Shared accounts or outdated passwords leave client data vulnerable to cybercriminals. Missing MFA (multi-factor authentication) further increases risk.
Tech Advisors enforces role-based access, centralized MFA, and consistent security measures across your environment.
4. Neglecting employee security awareness training
Social engineering attacks made up 36% of intrusions from May 2024 to May 2025, surpassing malware and exploits as the top breach method.
The IRS continues to report a surge in phishing and text-based scams targeting taxpayers and tax professionals, reflecting the cybersecurity threats CPA firms face during each filing season. These attacks spike during filing season, when your team handles large volumes of sensitive client data.
Because phishing and spear-phishing consistently target CPA firms, recurring employee training and documented internal controls are essential for SOC 2 readiness and compliance with the FTC Safeguards Rule. IRS Publication 4557 reinforces this by requiring phishing-awareness training, internal controls, and documented security procedures.
Tech Advisors strengthens this process by running monthly phishing simulations, tracking results, and generating the logs required for compliance reviews across firms like yours.
5. Overlooking FTC Safeguards Rule updates
The FTC Safeguards Rule requires you to update your policies, conduct risk assessments, and maintain up-to-date documentation. Many firms missed earlier milestones or still rely on outdated controls that fail to meet current compliance requirements. Out-of-date policies weaken protection for taxpayer data and reduce audit readiness.
Tech Advisors delivers continuous monitoring and scheduled policy updates so your controls evolve with GLBA, SOC 2, and IRS mandates.
6. Insufficient endpoint and device security
Laptops, desktops, and mobile devices are common entry points for breaches in firms like yours. Remote employees using personal devices create vulnerabilities that increase exposure to cyber threats, ransomware, and unauthorized access. Without uniform patching and device checks, even a single outdated endpoint can compromise your whole environment.
Tech Advisors enforces endpoint detection and response (EDR), centralized patching, and device compliance standards to close security gaps across your whole environment.
7. No incident response or disaster recovery plan
Without a documented incident response (IR) and disaster recovery (DR) plan, CPA firms lose critical time during a cyberattack. Slow response times increase the risk of data breaches, disrupt operations, and harm client relationships. A missing plan also fails SOC 2, GLBA, and FTC evidence requirements.
The AICPA SOC 2 Trust Services Criteria (2025) outlines the documentation firms must produce during response, containment, and recovery.
Tech Advisors builds repeatable IR and DR runbooks tailored to your firm’s accounting workflows, so your firm can act quickly and document every step.

FAQs
How can CPA firms help tax preparers strengthen IT compliance?
Give tax preparers automated monitoring of access controls, system logs, and cloud activity to surface issues early. This improves data security, protects client information, and supports compliance with the FTC Safeguards Rule and IRS requirements.
When should CPA firms use penetration testing to support SOC 2 and FTC Safeguards expectations?
Run penetration testing when you onboard new software, expand remote access, or update cloud environments. This validates your controls, reduces compliance risk, and provides the evidence regulators and auditors expect.
Why do CPA firms need both employee training and penetration testing to stay compliant?
Pair recurring phishing and security training with penetration testing to confirm that staff and systems can withstand real threats. This reinforces IT compliance for CPA firms, strengthens client protection, and aligns with SOC 2 and FTC Safeguards expectations.
