How to Check CPA Firm Compliance Before Hiring an Accounting Firm
Whether you're a business owner, CFO, or audit committee member selecting an accounting firm, doing proper compliance due diligence before hiring an accounting firm can save you from costly mistakes, legal liability, and reputational damage. This guide walks through the specific checks you should perform, the government databases to consult, and how Verdica can streamline the entire process.
Step 1: Verify the Fundamentals
Before evaluating performance or reputation, confirm the basics. The single most important compliance check for any cpa firm is state CPA license.
What to Look For
- state CPA license — This is non-negotiable. An expired, suspended, or revoked credential means the entity is not legally authorized to operate. Check this first and save yourself time on everything else if it fails.
- PCAOB registration (for public company audits) — Even if the license is current, a history of inspection results issues can signal ongoing problems. Look at both the volume and recency of issues. A single minor infraction five years ago is very different from a pattern of repeated violations.
You can verify these directly through the Public Company Accounting Oversight Board or use Verdica's accounting search to get an instant summary with links to source records.
Step 2: Check the Regulatory Record
Beyond basic licensing, dig into the cpa firm's history with regulatory bodies. This is where many business owner, CFO, or audit committee member selecting an accounting firms skip steps — and where the biggest risks hide.
Key Databases to Consult
The primary source is PCAOB registration and inspection reports, state board of accountancy license records, AICPA peer review results, and SEC enforcement actions against auditors. Here's what to look for in each:
- Registration Status verification — Confirm active status and check for any conditions, restrictions, or limitations on the credential.
- Inspection Results review — Look for formal enforcement actions, consent orders, fines, or penalties. Note whether issues were resolved or are still pending.
- Peer Review analysis — Review quantitative metrics where available. PCAOB often publishes comparative data that lets you benchmark one cpa firm against industry averages.
- Disciplinary Record assessment — Check for patterns in the most recent reporting periods. Improvement trends are a positive sign; deterioration warrants caution.
Red Flags That Should Stop You
Certain findings should give any business owner, CFO, or audit committee member selecting an accounting firm immediate pause:
- Revoked or suspended state status — This is a hard stop. Do not proceed regardless of explanations offered.
- Repeat violations of the same type — A single incident can be an anomaly. The same issue appearing multiple times suggests a systemic problem the entity is unable or unwilling to fix.
- Recent enforcement actions — PCAOB actions from the past 12 months are the most relevant. They indicate the current state of compliance, not ancient history.
- Failure to maintain professional liability insurance — This often indicates financial instability or unwillingness to invest in proper operations.
Step 3: Compare Against Peers
A compliance record doesn't exist in a vacuum. What looks like a concerning number of violations might be average for the industry, or what appears clean might actually be below peers.
Use Verdica to compare cpa firms in the same region or market segment. Our platform normalizes data across jurisdictions so you're making apples-to-apples comparisons. The trust score (300-850 scale) makes this especially straightforward — you can quickly see where an entity ranks relative to others.
What "Good" Looks Like
Based on our analysis of thousands of cpa firms in the Verdica database:
- Top quartile (score 720+): Clean regulatory record, all credentials current, minimal or no complaints, proactive compliance posture
- Median range (score 580-720): Generally compliant with occasional minor issues, credentials current, some complaints but at or below industry average
- Below median (score below 580): Notable compliance gaps, possible expired or restricted credentials, above-average complaint or violation volume
Step 4: Document Your Due Diligence
Compliance checking isn't just about making a good decision — it's about demonstrating that you made a responsible one. Document each step of your review process.
For each cpa firm you evaluate, record:
- Date of review and data sources consulted
- License/credential status confirmed as of that date
- Summary of violations or complaints found, with severity assessment
- Verdica trust score and grade at time of review
- Decision rationale — why you selected or rejected this entity
This documentation protects you if issues arise later. It demonstrates that you performed reasonable due diligence rather than selecting a cpa firm blindly.
Step 5: Set Up Ongoing Monitoring
Compliance is not a one-time check. The cpa firm you select today could lose their license, receive a major violation, or face regulatory action tomorrow.
Verdica allows you to monitor cpa firms over time. When their trust score changes — whether because of a new PCAOB action, an expired credential, or updated peer review data — you'll know about it. This turns compliance from a point-in-time exercise into a continuous process.
The Bottom Line
Checking accounting compliance before hiring an accounting firm comes down to five steps: verify fundamentals, review the regulatory record, compare against peers, document everything, and monitor ongoing. Each step reduces your risk exposure and improves decision quality.
