# Insurance for tax advisers, tax practices and auditors in Germany

> A missed objection, a forgotten deadline for an investment deduction, a payroll entry booked wrongly: in a tax practice small mistakes quickly cost clients five-figure sums. That is why German law makes professional indemnity compulsory for tax advisers (Steuerberater). This page explains the required sums, what they cost and where practices still have gaps.

## Are my payroll and bookkeeping staff covered?

Yes, if they are declared in the policy. Most tariffs charge a supplement per employee, around 80 to 170 euros a year for each full-time member of staff depending on the sum insured. If you hire new people and do not declare them, you risk a dispute over payment. Check once a year that the number in the policy is right.

## At a glance

- **Compulsory:** Professional indemnity under § 67 of the Tax Advisers Act (StBerG): at least 250,000 euros per claim and 1 million euros per year. Since August 2022 also for every professional firm; auditors (Wirtschaftsprüfer) need 1 million euros per claim under § 54 of the Auditors' Code (WPO)
- **Biggest risk:** Missed deadlines and planning errors that cost clients tax, surcharges or subsidies
- **Basic cover from:** around 260 euros a year for the compulsory cover of a small sole practice
- **Statutory accident insurer:** VBG (the Berufsgenossenschaft for administrative professions), compulsory for every practice with employees
- **Often forgotten:** Bookkeeping staff increase the premium but must be declared, otherwise there is a gap in cover

## What goes wrong in this trade

- **Tax office deadlines:** Objection, application and filing deadlines run in parallel for hundreds of clients. A single forgotten deadline can trigger late filing surcharges and lost tax benefits.
- **Planning errors:** Conversions, business splits and succession planning have consequences for years. An overlooked detail in inheritance tax quickly reaches six figures.
- **Payroll:** Wrongly calculated social security contributions often only surface in a payroll audit. The back payment for four years hits the client, and the recourse claim hits the practice.
- **Client data:** Tax advisers hold bank details, salaries and tax IDs of thousands of people. Attackers know this, and tax practices are among the businesses most often targeted.
- **Business advice:** Business plans, company valuations and financing advice sit at the edge of the tasks reserved to tax advisers. Whether they are covered depends on the wording of the policy.
- **Owner absence:** In a sole practice everything depends on one person. If they fall ill in the busy season, deadlines pile up and clients leave.

## The insurance you need

- **Professional indemnity** (Essential): Required by law under § 67 StBerG for every tax adviser and every professional firm; pays your clients' financial losses. https://www.nammert.com/en/insurance-broker-professional-indemnity.php
- **Cyber insurance** (Strongly advised): Covers forensics, recovery, reporting duties and downtime if your practice software or email accounts are attacked. https://www.nammert.com/en/insurance-broker-cyber-insurance.php
- **Business liability** (Strongly advised): Pays for injury and property damage, such as a client falling in your office; that is not a financial loss and is not part of the compulsory cover. https://www.nammert.com/en/insurance-broker-business-liability.php
- **Business contents** (Strongly advised): Replaces furniture and computers and pays to recreate documents after fire, water or burglary. https://www.nammert.com/en/insurance-broker-business-contents.php
- **Occupational disability** (Strongly advised): The professional pension scheme (Versorgungswerk) usually only pays for total disability; private cover closes the gap before that. https://www.nammert.com/en/insurance-broker-occupational-disability.php
- **Business interruption** (Depends on the business): Keeps paying salaries and rent if the practice cannot work for weeks after property damage. https://www.nammert.com/en/insurance-broker-business-interruption.php
- **Company pension (bAV)** (Depends on the business): Helps retain tax assistants in a tight labour market and brings tax advantages for the practice. https://www.nammert.com/en/insurance-broker-company-pension.php

## What it costs: example prices

The premium depends on fee income, the sum insured, the number of employees and the legal form. Specialist adviser titles (Fachberater) lower the premium with some insurers.

| Insurance | Example | Typical range |
| --- | --- | --- |
| Professional indemnity | Sole tax adviser, compulsory cover of 250,000 euros, fees up to 50,000 euros | around 260 to 820 euros a year |
| Professional indemnity | Sole practice, 250,000 euros, three full-time bookkeepers | around 900 to 1,300 euros a year |
| Professional indemnity | Partnership with three tax advisers, 1 million euros per claim, fees of 1 million euros | around 2,400 to 5,200 euros a year |
| Cyber insurance | Practice with ten workstations and remote access | around 800 to 2,500 euros a year |
| Business contents | Furniture and equipment worth 60,000 euros | around 130 to 400 euros a year |

For comparison: The compulsory cover of a small sole practice costs about as much a year as two or three simple income tax returns for employees.

## Practical tips from your broker

- Report every new full-time and part-time bookkeeper to the insurer, otherwise the premium basis is wrong and your cover can be challenged.
- Check that business advice such as business plans, subsidy advice and company valuations is explicitly covered.
- For planning advice on succession and conversions, choose at least 1 million euros per claim; the compulsory sum is rarely enough.
- When moving into a professional firm, check the sums under § 55f StBerG: 1 million euros per claim with limited liability, 500,000 euros without.
- Look for cyber cover that also pays for downtime in the busy season and provides a crisis service around the clock.
- Agree run-off cover before you give up or sell the practice; mistakes from past years often only surface in a tax audit.

## FAQ

### How high must a tax adviser's professional indemnity be?

At least 250,000 euros per claim, with an annual maximum of at least 1 million euros. For firms with limited liability, 1 million euros per claim applies.

### What does professional indemnity for tax advisers cost?

For a small sole practice with compulsory cover around 260 to 820 euros a year. With staff and a higher sum, the premium quickly rises to 1,000 euros or more.

### Does the tax advisory company need its own cover too?

Yes. Since the reform of professional law on 1 August 2022, every professional firm must have its own professional indemnity, whatever its legal form.

### What applies to auditors?

Auditors need professional indemnity of at least 1 million euros per claim under § 54 WPO. If you hold both qualifications, you need a policy that covers both professions.

### Does the insurer pay my client's late filing surcharges?

Yes, if they are caused by a mistake of the practice, such as a forgotten deadline. Surcharges the client caused himself are not covered.

### Do I also need cyber insurance?

Professional indemnity pays your clients' losses, not your own costs after an attack. Only cyber insurance pays for forensics, recovery and downtime.
