Accounting Firms: Protect Your Clients' Tax Data with Secure AI

The Responsibility of Accounting Firms

As an accounting or tax advisory firm, you handle your clients' most sensitive data: tax returns, payrolls, bank accounts, assets. Trust is your most valuable asset.

The Risk of Using Public AIs

Many accounting firms are using ChatGPT or Claude to:

• Query doubts about tax forms
• Review declarations
• Search for applicable regulations
• Draft communications with Tax Agency

The problem: Every time you paste client data into a public AI, you are:

1. Violating GDPR (Art. 32 - Processing security)
2. Exposing information to uncontrolled jurisdictions
3. Risking your clients' trust
4. Failing your duty as Data Processor

Use Cases for Accounting Firms

1. Queries about Tax Forms

With BOE expert: "Which boxes of form 303 should I fill in for a company exporting to UK after Brexit?"

AI gives you the answer with BOE references, without manual searching.

2. Analysis of Regulatory Changes

Problem: Keeping up with all tax changes Solution: Ask the expert about updates

"Have there been changes in R&D deductions in 2024?"

3. Internal Knowledge Management

With private experts:

• Index your internal procedures
• Resolved client cases (anonymized)
• Document templates
• Relevant binding consultations

When an employee has a question, they resolve it in seconds without bothering seniors.

4. New Employee Training

Juniors can consult the private expert to:

• Learn procedures
• Understand typical cases
• See examples of well-done documents

Reduce onboarding time from months to weeks.

GDPR Compliance for Accounting Firms

As Data Processor, you must:

Art. 28 GDPR - Obligations:

• Only process data following Controller's instructions (your client)
• Guarantee confidentiality
• Implement appropriate technical security measures
• Not subcontract without authorization

Using public AIs without guarantees = Serious breach

allows you to comply because:

• ✅ Processing on EU servers (or local on Desktop)
• ✅ No third-party subcontracting
• ✅ No data use for training
• ✅ Complete traceability
• ✅ DPA (Data Processing Agreement) available

Security Checklist

Before using any AI with client data:

• Is data processed in EU?
• Is there a signed DPA (Data Processing Agreement)?
• Can I audit what happens with data?
• Does the provider comply with GDPR?
• Is there written guarantee of no use for training?
• Can I delete data on demand?

If you can't check all, don't use it with client data.

Conclusion

Accounting firms need AI to compete. But not at any price. Your reputation and your clients' trust are worth more than any time savings.

gives you both: efficiency and security. No compromises.
