Am I liable if I make a mistake with AI at work?

In short

Am I liable if I make a mistake with AI at work? Only to a limited extent. In Germany an AI mistake is treated like any other mistake at work: with slight negligence you pay nothing, with gross negligence often the full amount. Towards customers your employer is liable first. The real risk is copying company data into banned AI tools. In the public sector, duty liability cover costs about EUR 19 to 71 a year.

Duty liability add-on, administration, police, universities	about EUR 33 a year
Duty liability add-on, technical services	about EUR 71 a year
Legal expenses including employment, single, four modules	about EUR 25 to 32 a month
Personal liability, single, for comparison, no work cover	about EUR 40 to 120 a year

Worked example

Wrong AI summary in a quote

A clerk lets an AI summarise a specification. One item is missing from the quote, and the company bears EUR 8,000 in extra costs.

Loss to the company	EUR 8,000
Usual check done, error hard to spot	slight negligence, EUR 0 for the clerk
No check despite instructions	medium negligence, shared according to circumstances
Banned AI tool used with customer data	gross negligence possible, up to EUR 8,000

How much the clerk pays depends only on how carefully she handled the AI output. The employer has to prove her fault.

Legally, an AI mistake is a work mistake

The AI itself is not liable, it is a tool like a spell checker or a spreadsheet. If you use a wrong AI answer at work, what matters is how carefully you worked: did you check the AI output the way people in your job normally would?

German labour courts limit employee liability (innerbetrieblicher Schadensausgleich). With slight negligence you pay nothing, with medium negligence the loss is shared, with gross negligence and intent you usually pay in full. This applies to a mistake with AI at work just as it does to a typing error.

AI mistake at work	Usual outcome
Small error in an AI translation despite the usual check	slight negligence, you are not liable
AI text sent to a customer without checking	medium negligence possible, loss shared
Customer data pasted into a free AI tool despite a clear ban	gross negligence possible, liability up to the full amount
AI result deliberately manipulated	intent, full liability
Employer demands AI use without rules or training	counts in your favour when fault is weighed

What your employer owes you when using AI

Since 2 February 2025, companies that use AI must take measures that build the AI literacy of their staff (Art. 4 of the EU AI Act). The Digital Omnibus of July 2026 softened this: the company does not have to guarantee a certain level for each individual.

It still matters for your liability. If AI tools were introduced without rules, approval or training, your mistake weighs less. A written AI policy therefore protects both sides.

When a customer loses money through a wrong AI answer

If an employee sends a customer a faulty AI result, the employer is liable to the customer first, because it answers for its staff (section 278 BGB). Wrong advice usually causes pure financial loss, which financial loss liability cover (Vermögensschadenhaftpflicht) covers, while basic business liability often does not.

Whether the employer then claims from you depends on your degree of fault again. It has to prove that fault (section 619a BGB), and it may not set off the claim against the part of your salary that is protected from seizure (section 394 BGB).

Data protection is the biggest AI risk at work

Pasting names, health data or contract details of customers into a freely available AI tool can breach data protection law. Anyone who suffers damage as a result can claim compensation from the controller (Art. 82 GDPR), which is usually your employer, not you.

If there is a clear ban in your company and you knowingly ignore it, a court may treat that as gross negligence. Your employer can then recover most of the loss from the AI mistake from you.

Which insurance helps with AI mistakes at work

Personal liability insurance (Privathaftpflicht) usually excludes work activities, so it will not pay for a mistake with AI at work. Public sector staff can add duty liability cover (Diensthaftpflicht) cheaply. Civil servants are liable to their employer only for intent and gross negligence (section 48 BeamtStG).

If you dispute a claim with your employer, legal expenses insurance with employment cover helps. If you work with AI as a freelancer, the employee rules do not protect you, and you need professional indemnity or financial loss cover.

When you do not need your own cover

As an employee in the private sector who uses AI for texts, summaries or research, you usually do not need your own liability cover for AI mistakes. The company carries slight errors, and its insurance deals with customer claims. Approved tools and your own checks matter more than a policy.

Advice on AI at work and liability

Norman Nammert works as an insurance broker (Versicherungsmakler) and can check whether your policies cover the work risks of using AI, from duty liability to employment legal expenses. The commission is paid by the insurer, so the advice is free for you.

Step by step

Read your company's AI rules and ask for unclear points in writing.
Use only approved AI tools and never paste customer data into free services.
Check every AI result as is usual in your job and note the check briefly.
Report a mistake as soon as you notice it so the loss stays small.
Do not sign an acknowledgement of debt and involve the works council, your union or legal expenses cover.

Checklist

Questions and answers

Frequently asked

Is the provider of the AI tool liable for the mistake?

Hardly for financial losses in your company, that is governed by its terms of use.

For software placed on the market from 9 December 2026,

the new German product liability law applies,

but only to personal injury, property and private data damage.

Does my personal liability insurance pay if I make a mistake with AI at work?

Usually not, because work activities are excluded.

Public sector staff can add duty liability cover.

Do I have to prove that I checked the AI result?

No, your employer must prove your fault (section 619a BGB).

A short note of your check still helps if there is a dispute.

Can my employer deduct the loss from my salary?

Not freely.

It may not set off against the protected part of your wages (section 394 BGB),

and otherwise only within your limited liability.

What applies to civil servants who use AI?

Civil servants are liable to their employer only for intent and gross negligence (section 48

BeamtStG).

Duty liability cover protects against that recourse.

What if I work with AI as a freelancer?

Then the employee protection rules do not apply.

You are liable to your client under the contract and need professional indemnity or financial loss

cover.
