Sabbatical and Long-Term Accounts: Banking Time to Study

In first consultations it is almost always the same calculation. Someone wants to study alongside work, the weekly hours do not add up, and the only solution on the table is to cut hours. Work less, earn less, and pay tuition on top.

There is a second route, and it is rarely mentioned, because in most companies it exists but has been filed away as an early-retirement instrument. With a long-term account you do not give up salary. You move it.

The difference in one sentence

With part-time work under section 8 TzBfG you trade money for time. With a time-value credit you earn the money first and take the time later.

The third row is why the effort pays off. Leave drawn from a time-value credit counts as continued employment for social insurance purposes. You stay covered through your employer, your pension entitlement keeps growing, and you remain covered by unemployment insurance. With unpaid special leave that stops after one month, and from then on you pay for health insurance yourself.

What is a long-term account in legal terms?

The basis is set out in sections 7b to 7f SGB IV. It requires a written time-value agreement between you and your employer. Four points in it are not negotiable, because the law prescribes them:

1. The credit is held in money, not in hours. Banked hours are therefore converted into pay when they are booked in.
2. The employer guarantees the nominal value of the pay contributed. You get back at least what you put in.
3. The credit is protected against insolvency (section 7e SGB IV), usually through a trust arrangement.
4. The leave serves a purpose agreed in advance. Further education is explicitly one of them.

Contributions typically come from overtime, untaken leave above the statutory minimum, one-off payments such as Christmas and holiday pay, or a fixed percentage of ongoing pay. The tax logic is simple: during the saving phase no wages are paid out, so neither tax nor contributions fall due. Both become payable only during the leave, usually at a lower rate.

The disruption event, and why everything hinges on it

A time-value credit is tied to its purpose. If it is not used as intended, a so-called disruption event occurs. The most common triggers are the end of the employment relationship without a transfer of the balance, the employer's insolvency, and the death of the employee.

The consequence is unpleasant: the entire balance is paid out at once and is fully subject to contributions and tax in that single year. Someone who has saved over six years can trigger a jump in progression that eats a substantial part of the benefit.

For you that means three things, and the third is the one most often overlooked:

• Timing. The saving period and the intended study phase should line up. An account that is only full after you graduate does not help you with this degree.
• Intention to move on. If you are explicitly planning your degree as a springboard to another employer, a large balance at the point of leaving is a risk. A transfer to the German pension insurance is possible, but it has to be applied for and comes with conditions.
• Repayment clause. If your employer also pays the tuition, a minimum service period regularly comes with it. What is permissible there is covered under repayment clauses in further education. A commitment and a balance together can hold you longer than you intended.

What if there is no long-term account?

Not every business runs time-value credits, and in small companies the administrative effort often does not pay off. That leaves two options, both worse, but workable.

Unpaid special leave is the simplest route and the most expensive. There is no statutory right to it, so your employer has to agree. For an exam phase of four to six weeks it is practical, because contribution cover still exists in the first month. For a whole semester, factor in the health insurance you will then pay yourself.

The part-time model with a block of leave is the more elegant substitute. You work at eighty per cent for four years, say, draw eighty per cent of your salary throughout, and take the banked time in one block in the fifth year. Economically that is the same as a time-value credit, only without its insolvency protection and without the nominal value guarantee. Which is exactly why the question of how your balance is secured matters even more here than with a formal account.

Austria and Switzerland

This legal position applies to Germany. In Austria the relevant framework is a different one: educational leave (Bildungskarenz) expired on 01.01.2026 and has been replaced by the Weiterbildungszeit, with considerably stricter requirements. What applies there today is covered under further education time in Austria.

Switzerland has no statutory model of this kind. Sabbaticals there run through individual contracts or staff regulations, and the tax treatment of further education costs is the more important lever. You will find more on that under deducting further education costs in Switzerland.

What does this mean for your study plan?

A long-term account does not change how much you can manage in total. It changes when you manage it. In a degree alongside work that is worth more than it sounds, because the load is never evenly spread. Modules can be handled over months on the side, a thesis rarely can.

So the typical application is not a whole semester but a block: eight to twelve weeks of leave for the bachelor's or master's thesis, on full pay. People who work that through often reach a different conclusion than they do with a permanent cut in hours.

How many credits are realistic per semester in your case is covered under ECTS per semester. And before you organise time at all, it is worth checking how many modules you can skip: the credit transfer check shows you that in two minutes.

This article sets out the legal framework and does not replace legal or tax advice. Particularly with disruption events and the transfer of a balance, a specialist's view is worth it, because real money is involved.

Conclusion: the order to work in

1. First check whether a time-value or long-term account already exists in your collective agreement or a works agreement. Usually it does.
2. Confirm in writing whether further education is named as a permitted purpose. If it is not, that is the point you negotiate, not the account itself.
3. Ask to see the insolvency protection under section 7e SGB IV in concrete terms before your first contribution.
4. Set the saving period so that the leave falls on your thesis, not on an arbitrary semester.
5. Negotiate leave and a contribution to costs in one conversation. Doing it one after the other rarely gets you both.

If you are unsure whether your plan works better through part-time hours, a time-value credit or no leave at all, book a free initial consultation. This decision is made once, and it shapes the entire duration of your studies.
