CPA Firm Compliance: Why a WISP is a Must-Have, Not a Nice-to-Have
If you’re running a CPA firm, you’ve likely heard about the growing need for tighter data security. With the rise in cyber threats and regulatory changes, CPA firm compliance is no longer optional. One of the biggest compliance requirements now is having a Written Information Security Plan, or WISP. If your firm isn’t already on top of this, now’s the time to act.
What is a WISP?
A WISP is a written document that outlines how your firm protects sensitive data like client financials, tax records, and personal information. It covers both the technical side (like firewalls and backups) and the human side (like staff training and access control).
Think of it as a roadmap for how your firm keeps client information safe. Unlike a generic template you might download online, your WISP needs to be tailored specifically to your firm, your systems, your risks, your staff, and your operations.
Why CPA Firms Must Comply
CPA firm compliance with WISP requirements became mandatory when the Federal Trade Commission (FTC) updated its Safeguards Rule in 2023. This rule used to only apply to banks, but now it covers all non-bank financial institutions, including CPA firms that do taxes, offer financial advice, or prepare financial statements.
It doesn’t matter how big or small your firm is. If you handle personally identifiable information (PII), you’re required to have a WISP in place. That’s the law.
On top of that, the IRS has its own set of rules (Publication 4557) that also require CPA firms to protect taxpayer data. Between the FTC, IRS, state privacy laws, and client expectations, CPA firm compliance has become a must-have, not a nice-to-have.
Common Mistakes CPA Firms Make
A lot of firms think they can just download a fill-in-the-blank WISP template and call it a day. That’s one of the biggest mistakes you can make. Regulators expect your WISP to reflect your actual risks, not some generic checklist.
Here are other common errors:
No formal risk assessment. Without this, your plan won’t truly address your firm’s real risks.
Thinking cybersecurity is just an IT thing. A WISP isn’t just about having antivirus software. It also covers employee training, incident response, and vendor management.
Not assigning responsibility. The FTC wants you to name a “Qualified Individual” to oversee your security program. Many firms skip this entirely.
Forgetting to update the plan. A WISP isn’t something you do once and forget. It needs to be reviewed and tested at least once a year.
Not training staff. Sending one security email a year isn’t enough. Real WISP compliance includes monthly or quarterly security training.
In short, cutting corners on your WISP puts your firm at risk, not just legally, but financially and reputationally.
Real Consequences for Non-Compliance
Let’s talk about what happens if your firm doesn’t meet CPA firm compliance requirements. The FTC can fine you up to $46,000 per violation per day, and yes, they can stack violations. The IRS can fine you and even revoke your PTIN credentials if you mishandle taxpayer data. State regulators can come after you too.
Fines aren’t the only risk. If your firm suffers a data breach and you didn’t have a WISP in place, you could lose clients, damage your reputation, and find it difficult (or impossible) to get cyber insurance coverage in the future.

Why You Can't Wait Any Longer
If your CPA firm hasn’t started working on WISP compliance, the time to start was yesterday. These rules went into effect in June 2023. Regulators are watching, and enforcement is increasing.
Don’t assume your current IT provider has it covered, so ask the hard questions. Do they understand what a Qualified Individual is? Have they helped you map your data flows? Do you have an actual incident response plan in writing?
CPA firm compliance isn’t about checking boxes. It’s about protecting your clients, your staff, and your reputation. It’s not just about IT, it’s about business responsibility.
