CPA firms hold some of the most sensitive financial data in the private sector—bank account numbers, Social Security numbers, and complete tax records for every client. This access makes firms valuable to clients, but also creates significant risk from a single careless click, a departing employee, or a compromised login. Employee activity monitoring has become a standard part of protecting client financial data, tracking who accessed what system and when. However, it only works effectively and remains legal when built on a clear written policy rather than software quietly installed on everyone’s laptop.
Establishing a Legal Monitoring Policy
Firm owners should begin by writing a policy that defines exactly what is monitored, client file access, email, login activity, and why, along with identifying who within the firm can view the reports. This document serves as part of what the FTC Safeguards Rule expects from an accounting firm’s written information security program. State requirements vary, with New York, Delaware, Connecticut, and Illinois now requiring written notice or signed acknowledgment before employers monitor electronic activity. When in doubt, firm owners should consult employment counsel to ensure compliance.
Every employee, including seasonal tax-season staff and contractors with system access, must provide signed acknowledgment of the monitoring policy. Monitoring should be scoped to firm-owned systems and accounts only, leaving personal devices and personal email outside its reach unless a specific BYOD policy states otherwise. Firms should enable audit logging inside tax and accounting software, not just at the network level, to track which client files a specific login has accessed.
Limiting Access and Managing Logs
To prevent the monitoring reports themselves from becoming a new point of exposure, access to viewing monitoring data should be limited to a small group, typically firm leadership and IT support. Firms must establish a retention schedule for logs rather than keeping them indefinitely, and store them securely. When reviewing reports, the focus should be on identifying real red flags such as a login accessing client files outside that employee’s normal workload, rather than micromanaging billable hours.
This approach addresses recurring client questions about data protection. Clients may wonder how they can know the person handling their taxes isn’t looking at other clients’ financial information. Access should be role-based and logged, meaning only staff assigned to a specific account can open those records, with any access outside the norm flagged automatically.

Client Questions and Trust Building
If something happens to client data, the firm needs to know quickly. Monitoring and audit logging are designed for exactly this scenario, unusual access patterns such as a login pulling records at 2 a.m. or downloading an unusual volume of files get caught rather than discovered months later. Employees sign an acknowledgment of the policy, which represents the same kind of safeguard used at banks and law firms, not a sign of distrust toward any individual staff member.
Monitoring employee activity is not just a compliance requirement, but also a way for accounting firms to build trust with their clients. By clearly explaining how client data is protected and who has access to it, firms can demonstrate a higher level of security and transparency than those that simply claim to have a policy in place. This is particularly important for accounting firms, which handle highly sensitive financial information for their clients.
A written policy paired with technical controls to back it up, reviewed at least once a year as both state laws and firm systems change, transforms activity monitoring from a liability into a genuine differentiator. Clients are increasingly asking these questions themselves, making transparency about data protection practices a competitive advantage.
