Positive hours are not an exception. In project-based companies, they are part of everyday operations: client appointments intensify, sprints run over, a colleague falls ill and leaves a gap that others fill. What seems normal in the short term accumulates in working time accounts — often without HR, project management, or executive leadership knowing the current balance.
According to the Federal Statistical Office, around 4.4 million employees in Germany regularly worked overtime in 2024. The majority — specifically 71 percent — booked this overtime into a working time account. The Institute for Employment Research (IAB) puts the average unpaid overtime for 2025 at 15.6 hours per employee per year.
For a team of 40 employees, that is more than 620 hours that, without structured management, are neither systematically reduced nor correctly paid out. The real effort arises when things are clarified retrospectively: when employees demand their compensation, documentation is incomplete, and HR must make decisions on the basis of insufficient data.
How positive hours affect the project level:
- Accumulated time accounts without a cap limit threaten liquidity planning as soon as payout entitlements arise
- Undocumented positive hours cannot be refuted by the employer in the event of termination
- Employees without real-time transparency of their time account escalate more frequently in performance reviews
- Missing thresholds delay HR intervention until a critical point is reached
- The Working Hours Act requires compensation within defined periods, which is regularly missed without structured monitoring
What Positive Hours Mean Legally
Working Time Account and Legal Framework
Positive hours arise when actual working time exceeds the contractually agreed target hours and this difference is posted to a working time account. The account records positive balances (positive hours) and negative balances (negative hours).
The Working Hours Act (Section 3 ArbZG) limits daily working time on working days to eight hours. An extension to up to ten hours is permissible if an average of eight hours per day is not exceeded within six calendar months or 24 weeks. The working time account structurally represents this compensation.
The specific design — that is, cap limits, maximum balances, compensation periods, and approval requirements for overtime — must be regulated in the employment contract, a works agreement, or the applicable collective agreement. If these provisions are missing, interpretive leeway arises that can work against the employer in the event of a dispute.
Paying Out Positive Hours: Tax and Legal Consequences
When positive hours may be paid out depends on the contractual or operational provision. In principle, payouts are permissible when the contract provides for this. The rule is: paying out positive hours triggers full income tax and social security liability. The payout is treated as regular remuneration and increases taxable income in the month of payment.
Tax-free supplements, such as those for night, Sunday, or public holiday work, do not apply to normal positive hours payouts. Blanket settlement clauses such as “all overtime is considered included in the salary” are, according to established case law of the Federal Labour Court, invalid if no specific quantitative limit is stated. Details on the correct calculation and compensation of overtime can be found in the article on calculating overtime.
Time Off in Lieu as the Preferred Compensation Mechanism
Time off in lieu generally takes precedence over payout, unless another provision exists. The employer determines the timing of the compensation but must take the legitimate interests of employees into account. Time off cannot be unilaterally scheduled for periods that are unreasonable for the employee.
Exclusion periods also play a role: many employment contracts and collective agreements provide that entitlements to compensation lapse after three to six months. Employees who cannot regularly view their account balance risk losing their entitlements. Employers who provide no transparency risk that forfeiture provisions will not take effect in the event of a dispute, because employees were unaware of their account balance. For employees working flexitime, a structured process from recording through to payroll is particularly important.

Implementation in Everyday Business: Where Positive Hours Grow Unchecked
Scenario 1: IT Services Provider with 45 Employees
An IT services provider manages eight client projects in parallel. Working hours are recorded by project, but in an Excel spreadsheet that is connected neither to the working time account nor to payroll. The status of the time accounts is not visible in real time to either HR or executive leadership.
In the fourth quarter, client projects intensify. Three employees accumulate between 25 and 40 positive hours per month. No threshold alerts the team lead. It is only at the annual review that the balances are discussed: one employee demands payout of 88 positive hours that would lapse under the contract in the following month. The unplanned payout burdens liquidity and generates a higher tax liability than calculated.
Had the company managed working time accounts digitally and in real time, the balance would have become visible in September with a defined threshold of 30 positive hours. HR could have coordinated the time off in lieu during the quieter part of the year, without any financial surprise.
The structural problem in this scenario: the Excel solution only provides a snapshot — at the moment when someone manually updates the file. Between two updates, balances arise that no one sees. In a company with 45 employees and eight parallel projects, it is highly likely that several time accounts reach critical levels simultaneously without a single automatic warning being triggered. The response is always reactive, after the conversation.
Scenario 2: Management Consultancy with 22 Consultants
In a management consultancy, flexible working hours apply. Travel times are treated differently depending on project assignment; time recording is largely done via manual timesheets. The result: positive hours arise at multiple levels simultaneously and are consolidated nowhere in full.
When a consultant resigns, she claims 94 positive hours, calculated back over the previous 16 months. The company can neither confirm nor refute the amount. The labour court follows the claimant's account. The payout, including social security contributions, exceeds €6,000 net. Procedural and legal costs are added on top.
Structured reduction of overtime is therefore not only about choosing the right time for compensation. It is about whether the account balance is documented in an audit-proof manner in the event of a dispute. A digital time tracking system would have recorded the balance to the day and made it exportable if needed.
The aspect most frequently underestimated in practice: the burden of proof principle in overtime claims works against the employer as soon as no objective recording system exists. A purely Excel-based document is rarely suitable in such proceedings to demonstrate that hours were not worked. The Federal Labour Court has made clear in several decisions that implementing a reliable time recording system is a duty of the employer under employment law.
Scenario 3: Digital Agency with 15 Employees
A digital agency offers its employees flexitime with a defined flexitime framework. Time accounts are updated manually once a month, based on the hours reported by employees. Gaps arise regularly when working hours are not consistently reported.
At the start of the year, three employees discover that their positive hours from the previous year were neither converted into time off in lieu nor paid out, even though the works agreement limits the annual carryover. What began as an administrative oversight becomes a trust issue. The agency management pays out retrospectively to resolve the conflict.
Had a digital system managed the time accounts automatically and stored the year-end date as a cap limit, the carryover would have become visible in time. HR could have proactively informed employees and coordinated the compensation.
From Manual Recording to Systematic Management
Managing Positive Hours in a Structured Way: What ZEP Delivers
ZEP records working hours assigned to projects and manages working time accounts automatically on the basis of stored target hours. As soon as an employee exceeds a defined threshold, the system triggers a notification to HR or team management. Project managers see in real time how many positive hours each team member has accumulated and can coordinate time off in lieu before a critical balance has built up.
For companies with DATEV or Lexware integration, the payroll-relevant time account data flows directly into payroll preparation. Manual transfers and the associated errors are eliminated. In the event of termination or an audit, a complete working time account record can be exported in just a few clicks — without gaps and audit-proof.
Transparency works in both directions: employees who can view their own account balance at any time ask fewer questions, escalate less frequently, and accept agreed compensation arrangements more readily. This reduces the need for discussion in one-on-one meetings and significantly relieves HR of routine enquiries. What is often underestimated: the manager saves time that was previously spent on reactive clarification and can invest it in capacity planning that avoids positive hours accumulating in the first place.
For companies with a works council, it is also relevant that a digital time recording system creates the foundation for viable works agreements. When time accounts are managed transparently and reliably, cap limits, compensation periods, and forfeiture provisions can be negotiated and communicated on a shared data basis. This strengthens all parties’ confidence in the fairness of the arrangements — which in everyday working life is worth more than any retrospective correction.
Conclusion: Five Measures for Clean Positive Hours Management
Step 1: Review your employment contracts and works agreements for complete provisions on working time accounts: cap limits, compensation periods, forfeiture deadlines, and payout conditions. Clauses without a specific quantitative limit are frequently invalid under Federal Labour Court case law.
Step 2: Ensure that all time accounts are maintained without gaps and in an audit-proof manner, regardless of whether trust-based working hours or flexitime applies. The employer’s documentation obligation applies equally in both models.
Step 3: Define a threshold (for example, 30 or 40 positive hours) above which HR is automatically notified. Set down the time-off-in-lieu process in writing before the first conflict arises. A defined process is easier to communicate than an ad-hoc decision made under pressure.
Step 4: Connect time recording and payroll preparation in a single system. Manual data transfers between two tools are one of the most common sources of error in payout calculations. The DATEV interface reduces this effort to a minimum.
Step 5: Give your employees access to their own account balance. Transparency reduces conflicts and builds confidence in the fairness of the arrangements. Those who know their balance bring this topic up less frequently in the next performance review.
FAQs
What are positive hours and how do they differ from ordinary overtime?
Positive hours refer to the positive balance on a working time account. They arise whenever an employee works more hours than contractually agreed, and are accumulated in the time account. Overtime in the strict sense refers to hours that exceed normal working time and are either compensated financially or offset by time off in lieu. In companies with working time accounts, additional hours worked typically flow into the account as positive hours.
When may an employer pay out positive hours?
Paying out positive hours is permissible when the employment contract, works agreement, or collective agreement explicitly provides for this. The payout is subject to regular income tax and social security contributions. Tax exemptions, such as those that apply to supplements for Sunday, public holiday, or night work, do not apply to normal positive hours payouts.
What happens to positive hours upon termination?
Upon termination, the employee is entitled to settlement of the account balance, either through paid time off or through a payout. If the employer cannot demonstrate the account balance in an audit-proof manner, they bear the burden of proof in the event of a dispute. Courts frequently follow the employee's account in such cases.
How long may positive hours be accumulated?
The maximum accumulation period is governed by the employment contract or works agreement. The Working Hours Act requires that extensions of daily working time be offset within six calendar months or 24 weeks. Contractually agreed exclusion periods may be shorter. In the absence of such provisions, the statutory limitation period of three years for wage claims applies.
Can the employer unilaterally determine when positive hours are reduced?
The timing of time off in lieu is fundamentally determined by the employer. However, the employer must take the legitimate interests of employees into account. Time off cannot be unilaterally scheduled for periods to which the employee has justified objections. Works agreements often regulate this compensation in concrete terms, for example through fixed compensation windows or minimum notice periods.
How can management identify early on when positive hours are becoming problematic?
The decisive factor is real-time transparency. Companies that manage working time accounts in a digital system can define thresholds above which HR or team management is automatically notified. Project managers can see early on where action is needed and coordinate time off in lieu before a critical balance builds up. Employees who have access to their own account balance also escalate significantly less frequently.
