What is a working time account and how does it work?

A working time account records the hours an employee has actually worked and compares them with the working hours agreed in the contract. Overtime or negative hours are booked to the account and can be balanced out through time off or payment.

What are the advantages and disadvantages of a working time account for employees?

The advantages are flexible working time arrangements and comp time. The disadvantages can be the expiry of overtime and the obligation to make up negative hours.

Am I obliged to make up negative hours?

So-called negative hours can only build up if the recording of working hours as part of the working time account has been agreed to. With that agreement, employees are also obliged to work off any negative hours they have built up.

How can a working time account be kept digitally?

A working time account can be kept digitally by recording working hours to the minute and assigning them to the hours account automatically. Digital time tracking solutions such as clockin help to show plus and negative hours transparently, keep to balancing periods and give employees access to their working time account at any time. That way businesses keep an overview without creating extra administrative work.

Working time accounts: rules, benefits and risks

What exactly is a working time account?

A working time account records the hours an employee has actually worked and sets them against the working hours agreed in the contract.

If an employee works more than agreed, overtime arises and is credited to the working time account. If they work less, negative hours arise, and these are documented in the account as well.

The aim of the working time account is to balance working hours out over a longer period instead of assessing them rigidly by the day or week.

How does a working time account work in practice?

In practice, a working time account works like this:

Daily working hours are recorded (e.g. digitally or via proof of hours)
Plus and negative hours are calculated automatically
A defined period governs when a balance has to be reached

Important: a working time account does not replace time tracking, it builds on it

In practice, working time accounts rarely fail because of the model itself, but because of how it is put into practice. What matters is that working hours are recorded cleanly, that plus and negative hours are calculated in a way that is easy to follow, and that employees can see them at any time. That is exactly where digital time tracking solutions come in.

What types of working time account are there?

Not every working time account is the same. Depending on how it is set up, several forms can be distinguished:

Short-term account

Balanced out within a few weeks or months
Common with flextime models
Focus: short-term flexibility

Annual working time account

Balanced out over a whole calendar year
Suitable for seasonal fluctuations
Common in the skilled trades or in service sectors

Long-term account

Balanced out over a very long period
Used for a sabbatical or phased retirement (Altersteilzeit), for example
Stricter legal requirements

Benefits of a working time account

A well-regulated working time account brings benefits for both sides:

For employees:

More flexibility in working hours
Extra hours balanced out with time off
Transparency about the hours worked

For employers:

Better management of peaks in work
Less short-notice overtime pay
Predictable staffing

Risks and drawbacks of a working time account

Without clear rules, a working time account can quickly become a problem:

Overtime builds up permanently
Negative hours put pressure on employees
Unclear expiry deadlines can lead to conflict
Without a digital solution, employees have no real transparency

That is why it is crucial to set the working time account out cleanly.

‍Overtime in the working time account: how is it balanced out?

Overtime arises when more is worked than agreed in the contract. It is collected in the working time account and balanced out later. Usually through:

comp time (e.g. an early end of shift, days off)
Payment (rarer, set out in the contract)

What matters is that it is clearly laid down:

when overtime may be taken
whether and when it expires
what upper limit applies

Negative hours in the working time account: what is allowed?

Negative hours arise when less is worked than agreed. The important points here:

Negative hours must not arise arbitrarily
They are only permissible if the employee causes them themselves
Employers may not book negative hours if they do not offer any work

The same applies here: how negative hours are handled has to be clearly regulated.

How many hours may a working time account cover?

The limits of the German Working Hours Act (Arbeitszeitgesetz, ArbZG) apply to working time accounts:

A maximum of 8 hours a day
In exceptional cases 10 hours, if this is balanced out
Usual upper limits for overtime per year are 100-150 hours

The specific limit depends on the employment contract or the works agreement.

Working time accounts and short-time work: what applies?

Special rules apply during short-time work:

As a rule, overtime should be used up before short-time work begins
During short-time work the working time account is usually frozen
No new negative hours may arise during this phase

Does an employee have to accept a working time account?

No. A working time account is not automatically mandatory.

It is only permissible if it:

is set out in the employment contract, or
has been introduced through a works agreement.

Without such a rule, the employee's consent is required.

What has to be set out in the contract for a working time account?

For a working time account to be legally compliant, the following points should be laid down:

Type of working time account
Method of time tracking
Upper limits for plus and negative hours
Balancing period
Expiry of overtime
Employees' rights to view their account

If these rules are missing, legal uncertainty is the result.

The question of how working hours are recorded is particularly important. Businesses have to make sure that hours are documented in full and can be viewed transparently by employees. Digital systems can help here to reduce sources of error and keep the working time account audit-proof.

What obligations does the employer have?

Employers are obliged to:

record working hours
keep to the statutory maximum working hours
process working time data in line with the GDPR
give employees access to their working time account.

A working time account does not release them from these obligations.

Keeping a working time account cleanly – what counts in practice

For a working time account to stay fair and legally compliant, three things are needed: reliable time tracking, transparent hours accounts and clear reporting for employers and employees.

Digital solutions such as clockin help businesses to record working hours to the minute and assign them to the working time account automatically. Employees can see at any time whether they are building up overtime or need to make up negative hours, while employers keep an overview and can step in early.

Conclusion: when does a working time account make sense?

A working time account makes sense when:

working hours fluctuate
flexibility is wanted
clear rules are in place
there is transparency for everyone involved.

Without clear agreements, however, conflict can arise quickly. What matters is not the model itself but how consistently and fairly it is put into practice.

Whatever tool you choose, one thing holds: a working time account only works if the rules are clearly defined, working hours are reliably recorded and everything is transparent for everyone involved. Digital systems can make this process easier – but they do not replace the agreement that employer and employee need to reach.
