Is an AI even allowed to talk to our clients?

Yes, as long as it's clear this is a digital assistant and no tax advice is given for an individual case. The AI answers organizational questions and routes advisory questions to you or your qualified staff.

How do you handle tax secrecy and confidentiality obligations?

For firms we recommend self-hosting by default: client data never leaves your infrastructure. The usual GDPR mechanisms also apply: a data processing agreement, retention periods, a log.

Can the AI request documents and send reminders?

Yes. If a document is missing for a deadline, the AI can automatically send a polite reminder with the exact requirement and note the arrival in the system once the client responds.

How does the AI handle tax season, when call volume explodes?

That's exactly what it's built for: it answers any number of calls in parallel. The effect is largest in season, because human capacity is scarcest right there.

AI for tax firms: client questions without the wait

The bottleneck today

At tax firms, a large share of client communication repeats itself: “Where’s my assessment?”, “What documents do you still need?”, “By when do I need to submit this?” These questions matter to the client but are rarely complex, and yet they’re often answered by the same qualified staff member who should really be doing the actual tax work.

Tax season makes it worse: the phone rings by the minute, the line is permanently busy, and clients urgently trying to submit a document can’t get through for days. Every interruption of a qualified staff member for a standard question costs twice: time for the call and time to get back into focused work.

What the AI takes over (a concrete day)

A client calls to ask whether their receipts for the VAT advance return are complete. The AI phone assistant checks the status in the system and gives an answer, or names specifically which document is still missing, where that’s defined.

On the website, a prospect asks the chatbot a general question about the firm’s services and the process for an initial consultation. The AI answers from the firm’s knowledge base and offers an appointment for an initial call.

A deadline approaches: three clients are still missing receipts. Instead of a staff member chasing each one individually, the agent automatically sends a friendly reminder with the exact requirement and marks the case as done once the document arrives.

Connecting to your systems

The connection to DATEV and comparable practice software runs, depending on the available interface, via automation software or via defined export processes. Appointments land in the firm’s calendar, document requests in the respective client folder. Where direct write access isn’t wanted for compliance reasons, we work with an approval step: the AI prepares, a staff member confirms.

Cost & benefit

Setup 1,500–3,500 € per building block, operation 150–400 € per month depending on client and call volume. The benefit shows most clearly in season: every hour a staff member doesn’t spend on standard follow-up questions is an hour for the actual advisory work, the work clients actually pay for.

Honest limits

The AI gives no tax advice for individual cases and makes no professional assessments, that stays with you and your staff. For complex or emotionally charged cases (e.g. an audit, a dispute with the tax office), the AI consistently hands off to a human. And because confidentiality matters especially in this field, we strongly recommend self-hosting here rather than the standard cloud variant.
