Record-Keeping Obligation in Germany: What the Working Hours Act Really Requires

19. May 2026 · HR-Tech, Recht & Compliance, Zeiterfassung, Arbeitszeitgesetz

Record-Keeping Obligation in Germany: The Current Legal Situation

For a long time, the rule in Germany was that working hours only needed to be recorded for certain groups of employees – for example, for marginal part-time workers (mini-jobs) or Sunday work. This changed fundamentally as a result of a landmark BAG ruling (Federal Labour Court).

The ruling obliges employers to put in place a system with which the total working hours of all employees can be recorded. This obligation arises from the employer's duty of care and employee protection – and is monitored by the trade supervisory authority (Gewerbeaufsicht).

BAG ruling on working time recording: Employers are obliged to introduce a system with which the working hours performed by employees can be recorded. Pure trust-based working hours without any monitoring are no longer permissible.

Violations of the record-keeping obligation under Working Hours Act (ArbZG) § 16 and § 22 can be punished with fines of up to 30,000 euros. Systematic violations may incur significantly higher penalties.

What Must Be Recorded According to the Working Hours Act?

The German Working Hours Act (ArbZG) regulates in several sections which working hours must be documented. The requirements have tightened considerably as a result of case law.

Mandatory Information under ArbZG and BAG Ruling

� Start of daily working time (exact time)
� End of daily working time (exact time)
� Duration of working time (in hours and minutes)
� Breaks (at least 30 minutes for shifts longer than 6 hours)
� Rest periods between working days (at least 11 hours)
� Overtime beyond the agreed working hours
� Sunday and public holiday work (with justification and compensation)

Special Record-Keeping Obligations under ArbZG § 16

Extended documentation obligations apply to certain forms of working time:

For Sunday and public holiday work: Full documentation including substitute rest day (ArbZG § 16 para. 2)
For night work: Recording of night work hours
For exceeding the 8-hour limit: Documentation of the extension and the compensatory rest
For on-call duty: Distinction between active work and standby

Who Is Affected by the Record-Keeping Obligation?

The record-keeping obligation applies to all employers in Germany – from sole traders to large corporations. The BAG ruling has clarified that the previous practice of only recording certain groups of employees is no longer sufficient.

Which Employees Are Subject to the Obligation?

� Full-time employees
� Part-time employees
� Marginally employed workers (mini-jobs) – already required by law for a long time
� Trainees
� Interns
� Working students
� Employees working from home or in mobile working arrangements
� Seasonal workers and temporary staff

Are There Any Exceptions?

The legal situation here has not yet been fully clarified. Under current case law, the following may be exempt:

Senior executives within the meaning of § 5 para. 3 BetrVG (a very restricted group of persons)
Managing directors with a significant ownership stake
Board members

Important: The term "senior executive" is interpreted very narrowly. Department heads, team leaders or authorised signatories (Prokuristen) generally do not fall under this category.

What Penalties Apply in the Event of Violations?

The trade supervisory authority and other occupational health and safety authorities of the federal states monitor compliance with the Working Hours Act. Violations are treated as administrative offences or, in serious cases, as criminal offences.

Violation	Legal basis	Fine
Missing recording of working hours	ArbZG § 22 para. 1 no. 8	up to €30,000
Improper retention of records	ArbZG § 22 para. 1 no. 8	up to €30,000
Exceeding maximum working hours	ArbZG § 22 para. 1 no. 1	up to €30,000
Violation of Sunday rest	ArbZG § 22 para. 1 no. 2	up to €30,000
Wilful endangerment	ArbZG § 23	Custodial sentence of up to 1 year

Important: These fines can be imposed per violation. With 20 employees without time recording, fines of up to €600,000 are therefore theoretically possible.

Practical note: The occupational health and safety authorities of the federal states enforce compliance with varying degrees of strictness. While some federal states are currently still focusing on information and advice, others are already imposing substantial fines. The trend is clearly moving towards stricter enforcement.

How Must Working Hours Be Recorded in Germany?

The Working Hours Act does not prescribe a specific form of time recording. However, the BAG ruling has defined clear requirements that also apply in Germany:

The Three Core Principles of Legally Compliant Time Recording

Objective: The recording must be based on actual measured values, not on estimates or flat-rate entries.
Reliable: The data must be correct, complete and traceable. The system must prevent manipulation or at least document it.
Accessible: Both the authority and the works council (if one exists) as well as the employees themselves must have access to the data.

Permissible Recording Methods

In principle, various methods are possible:

📱 Digital time tracking systems (app, software, terminal)
🕐 Electronic time clocks
📝 Handwritten timesheets (only with daily, immediate recording)
💻 Excel spreadsheets (only with change protection or full versioning)

However, not all methods meet the requirements for objectivity and reliability equally well.

Paper vs. Excel vs. Digital Time Tracking – A Compliance Comparison

Requirement	Paper timesheets	Excel spreadsheets	Digital time tracking
Objective recording	⚠️ Often entered retrospectively – problematic	⚠️ Manual entry – prone to errors	� Real-time stamping
Reliability	❌ Illegible, incomplete	⚠️ Formula errors possible	� Automatic validation
Accessibility	⚠️ Physically available	� Digitally available	� Accessible online at any time
Tamper-proofness	❌ No change history	❌ Can be altered arbitrarily without protection	� Audit-proof logging
Break regulation ArbZG	❌ Manual monitoring	⚠️ Formula required	� Automatic according to the law
Maximum working hours control	❌ Retrospective review	⚠️ Manual calculation	� Real-time warning
Retention obligation (2 years)	⚠️ Physical storage	� Digital, but backup required	� Automatic backup
Works council access	❌ Cumbersome	⚠️ Manual sharing	� Role-based access
Compliance risk	🔴 High	🟡 Medium	🟢 Low

Checklist: How to Fulfil the Record-Keeping Obligation in Germany

Review your current time tracking against this checklist:

� System Requirements

☐ A time recording system is in place and actively in use
☐ All employees (except those demonstrably exempt) are covered
☐ The system records working hours objectively (not on a trust basis)
☐ Timely recording is ensured (not retrospectively at the end of the month)

� Completeness of Data

☐ The start and end of each work shift are recorded
☐ Breaks from 6 hours of working time are documented (min. 30 min.)
☐ Breaks from 9 hours of working time are documented (min. 45 min.)
☐ Overtime beyond the agreed working hours is shown
☐ Sunday and public holiday work is documented separately
☐ Night work is flagged

� Tamper-Proofness

☐ Subsequent changes are either impossible or are logged
☐ A change history exists (who changed what and when)
☐ Employees cannot manipulate their own data without detection

� Accessibility

☐ Employees can view their own working hours at any time
☐ The works council (if one exists) has access to relevant data
☐ Records can be produced immediately during inspections

� Retention and Data Protection

☐ Records are retained for at least 2 years (ArbZG § 16 para. 2)
☐ For digital systems: a backup strategy is in place
☐ Access is governed by role-based controls (data protection under GDPR)
☐ Employees have been informed about data processing

Works Council and Co-Determination in Time Recording

In Germany, the works council has a mandatory right of co-determination regarding the introduction and design of time recording systems (BetrVG § 87 para. 1 no. 6).

What Does This Mean in Practice?

Time recording systems may only be introduced with the consent of the works council
The works council can insist on a works agreement (Betriebsvereinbarung)
The works agreement governs: recording method, data access, storage period, purpose of use
In the event of disagreement, the conciliation committee (Einigungsstelle) decides

Practical tip: Involve the works council at an early stage. Solutions developed together are better accepted by employees and lead to fewer conflicts. A well-drafted works agreement creates legal certainty for all parties.

What Happens During an Inspection by the Trade Supervisory Authority?

The responsible occupational health and safety authorities of the federal states (depending on the state: Gewerbeaufsicht, Amt für Arbeitsschutz, etc.) carry out both announced and unannounced workplace inspections.

What Is Inspected?

Existence of a recording system: Is there a functioning system at all?
Completeness: Are all mandatory details being recorded?
Currency: Is recording carried out promptly or retrospectively?
Compliance with maximum working hours: Is the 8-hour or 10-hour limit being observed?
Break regulation: Are the statutory breaks being granted?
Rest periods: Are the 11 hours of rest between working days being observed?
Sunday work: Is it permissible and are substitute rest days being granted?

Possible Consequences

In the event of violations, the authority may:

Set deadlines for remediation (typically: 4–8 weeks)
Impose fines (up to €30,000 per violation)
Issue prohibition orders (in cases of imminent danger)
File a criminal complaint (in cases of wilful, repeated violations)

Digital Time Tracking: The Safest Path to Compliance

Modern digital time tracking systems are specifically designed to automatically meet statutory requirements. The key advantages:

Automatic Compliance Assurance

� Objective real-time recording: Times are stamped at the actual moment
� Automatic break regulation: Reminders for mandatory breaks under ArbZG
� Maximum working hours warning: Notification when the 8/10-hour limit is about to be exceeded
� Audit-proof storage: All changes are logged
� Role-based access: Works council, employees, supervisors – everyone sees only what they are permitted to see
� Automatic backup: No data loss, 2-year archive maintained automatically

Particularly Important for Mobile Teams

When employees work on construction sites, at customer premises, in the field or from home, mobile time tracking via app is particularly valuable:

📱 Time tracking via smartphone (iOS and Android)
🌐 Offline functionality (usable even without internet)
🗣️ Multilingual support for international teams (e.g. German, English, Serbian, Albanian, Hungarian, Turkish, Slovak, Romanian, Bulgarian, Polish, Czech, Croatian)
📍 Optional GPS tracking (GDPR-compliant, only during working hours)
🏷️ NFC check-in at work locations
📧 Login without an email address (via SMS – ideal for blue-collar workers)

Common Mistakes in Working Time Recording

❌ Mistake 1: "We Are Still Waiting for a Legislative Clarification"

Many companies are hoping for a new law that will regulate the details. This is risky: the BAG ruling already applies now. Those who wait risk fines.

❌ Mistake 2: Trust-Based Working Hours Without Any Monitoring

"Our employees work autonomously" – that is not a free pass. Even with flexible models, actual working hours must be documented.

❌ Mistake 3: Flat-Rate Recording Instead of Actual Hours

"8 hours per day" as a standard entry is not sufficient. The hours actually worked must be recorded, even if they deviate from the norm.

❌ Mistake 4: Missing Works Agreement

In companies with a works council, a works agreement is mandatory. Without one, the time recording violates co-determination rights – with corresponding legal consequences.

❌ Mistake 5: No Retention of Records

Under ArbZG § 16 para. 2, records must be retained for at least 2 years. Older data must also be producible during inspections.

❌ Mistake 6: Excel Without Versioning

Excel spreadsheets that can be overwritten at will do not meet the reliability requirement. It must be traceable who changed what and when.

Conclusion: The Record-Keeping Obligation Is Coming – or Is Already Here

The legal development in Germany is unambiguous: the BAG ruling already obliges employers to record working hours in full. Even if a new law is still pending – the obligation exists.

Anyone who still relies on paper timesheets or trust-based working hours without monitoring today is taking on considerable risks:

Fines of up to €30,000 per violation
Liability for working time violations
Conflicts with the works council
Legal uncertainty in the event of employee claims

The good news: with a well-designed digital system, complying with the record-keeping obligation requires little effort. Modern solutions automatically meet the statutory requirements while at the same time significantly reducing administrative workload.

Three key takeaways:

The obligation applies now: The BAG ruling is binding, even without a new law.
Digital solutions are more reliable: They automatically fulfil the requirements for objectivity, reliability and accessibility.
The works council must be involved: Time recording is subject to co-determination – early coordination saves conflicts.

Die 10 häufigsten Fragen zur Aufzeichnungspflicht in Deutschland

Is time tracking mandatory in Germany?

Yes, following the BAG ruling (Federal Labour Court), employers are required to introduce a system capable of recording the total working hours of all employees. This obligation arises from the duty of care and employee protection legislation. Pure trust-based working hours without any monitoring are no longer permissible.

What penalties are faced for failing to record working hours?

Violations of the recording obligation under ArbZG § 22 can result in fines of up to €30,000 per offence. In the case of systematic or wilful violations, custodial sentences of up to one year may additionally be imposed. Penalties can multiply when multiple employees are affected.

Does the recording obligation also apply to part-time employees and mini-jobbers?

Yes, the recording obligation applies to all employees – full-time, part-time, mini-jobs, casual workers, interns and working students. For mini-jobs, the recording obligation already existed prior to the BAG ruling. The only exceptions are genuine senior executives within the meaning of § 5 Para. 3 BetrVG – a very small group of persons.

Does the works council have to approve the time-tracking system?

Yes, in companies with a works council, the council has a mandatory right of co-determination when introducing time-tracking systems (BetrVG § 87 Para. 1 No. 6). Introduction without the works council's approval is unlawful. As a rule, a works agreement is concluded that governs details such as the recording method, data access and purpose of use.

Is a spreadsheet sufficient for time tracking?

Excel is generally permitted, but only under certain conditions: the spreadsheet must be maintained on a daily basis, subsequent changes must either be prevented or fully logged, and versioning must be in place. Excel spreadsheets without change protection do not meet the reliability requirements. Digital time-tracking systems offer greater legal certainty.

How long must working time records be retained in Germany?

Pursuant to ArbZG § 16 Para. 2, working time records must be retained for at least 2 years. This period begins at the end of the calendar year in which the record was created. With digital systems, automatic backups should be set up to prevent data loss.

What does the trade supervisory authority check during a working time inspection?

The trade supervisory authority or occupational health and safety authority checks whether a time-tracking system exists, whether all mandatory details are recorded (start, end, breaks), whether maximum working hours are being observed, and whether records are made in a timely manner. The documents must be able to be presented immediately during inspections – lengthy search times are already considered a violation.

Does the recording obligation also apply when working from home?

Yes, the recording obligation applies regardless of the place of work. Whether working from home, on construction sites, at a client's premises or in the field, the start, end and duration of working hours must be documented. An app-based mobile time-tracking solution is particularly practical here, as employees can record their hours directly on site.

Can employees waive time tracking?

No, the recording obligation is a statutory duty of the employer that cannot be waived – not even by mutual agreement with the employee. Even if employees work on a trust basis, their actual working hours must be documented.

When will the new working time recording law come into effect?

A specific new law has not yet been enacted. However, the BAG ruling is already in force and is binding on all employers. Those waiting for a new law risk fines – the recording obligation already exists today on the basis of current case law and the Working Hours Act.
