Every autumn the same disputes land on our desks: the Christmas bonus that suddenly „doesn’t apply this year”, the 13th salary withheld because the employee resigned, the repayment demand after a January exit. The decisive point that most employees — and many employers — get wrong: whether you can claim the payment depends on its legal character, and payments that remunerate your work cannot be taken away by „voluntary” labels, cut-off dates or unilateral decisions. German case law has dismantled most of the standard employer clauses; what survives is narrower than HR departments like to admit.
Three different animals: 13th salary, Gratifikation, mixed-character bonus
German law distinguishes special payments (Sonderzahlungen) by their purpose:
- 13. Gehalt (13th salary): pure additional remuneration for work performed, typically paid in November or December. Legally it is salary — earned pro rata throughout the year, like every other euro of your pay.
- Gratifikation with pure loyalty character: a payment rewarding past and future loyalty only (rare in its pure form) — e.g. a genuine anniversary or „thank you for staying” payment that does not depend on work performed.
- Mischcharakter (mixed character): the most common reality — a „Weihnachtsgeld” that rewards both work performed and loyalty. The BAG treats mixed-character payments largely like remuneration where it matters.
Why the classification matters: remuneration-character payments are earned pro rata, survive cut-off-date clauses, and cannot be made „voluntary” retroactively. Pure loyalty payments allow the employer more drafting freedom. Courts look at substance, not labels — if the amount scales with salary or performance, or the contract links it to the work relationship generally, remuneration character is indicated.
Where the claim can come from
- Employment contract: the clearest basis — „the employee receives a 13th monthly salary payable with the November payroll”.
- Betriebliche Übung (company practice): the employer that pays a Christmas bonus unconditionally three years in a row creates a binding entitlement for the future — even without any written promise. The three-payments rule is settled BAG case law.
- Gesamtzusage: a general announcement to the workforce („all employees receive…”) binds the employer like a contract term.
- Tarifvertrag or Betriebsvereinbarung: many collective agreements provide annual special payments (Jahressonderzahlung) with their own detailed conditions.
- Equal treatment: if comparable colleagues receive the payment, excluding you needs an objective reason (arbeitsrechtlicher Gleichbehandlungsgrundsatz).
„Freiwillige Leistung” — why the standard reservation usually fails
Employers try to prevent claims with Freiwilligkeitsvorbehalte („this payment is voluntary and creates no future entitlement”). The BAG has cut these down drastically:
- A clause combining „voluntary” with „revocable” is self-contradictory and invalid (a payment cannot simultaneously create no entitlement and be an entitlement subject to revocation) — BAG, 10 AZR 526/10.
- Blanket contract clauses declaring all future special payments voluntary fail the transparency and fairness control of § 307 BGB, particularly where the payment in substance remunerates work.
- A „voluntary” note on the payslip alone does not prevent a betriebliche Übung if the payments themselves were unconditional.
Practical consequence: treat every „it was always voluntary” defence with scepticism. In a large share of the cases we see, the reservation is invalid and the claim exists. The same BAG lines govern other bonus types — see discretionary bonuses.
Stichtagsklauseln: cut-off dates are mostly dead for remuneration
Classic clause: „Payment only to employees in an unterminated employment relationship on 1 December.” The BAG holds such cut-off clauses invalid where the special payment (also) remunerates work performed — you cannot retroactively strip pay that was earned through the year by attaching a survival condition (BAG, 10 AZR 848/12). Only where a payment has pure loyalty character, detached from work performance, can the employer condition it on being employed at a cut-off date.
Since genuinely pure loyalty payments are rare, most Stichtagsklauseln in standard contracts are unenforceable — including against employees who resigned themselves.
Rückzahlungsklauseln: when you must pay a bonus back
Repayment clauses („the Gratifikation must be repaid if the employee leaves before 31 March”) are permissible only for loyalty-character payments and only within limits developed by the BAG:
- Small amounts (up to roughly €100): no repayment obligation may be attached at all.
- Up to one month’s salary: the clause may bind the employee at most until 31 March of the following year.
- Larger amounts: somewhat longer binding periods only for payments clearly exceeding a monthly salary, and never disproportionately.
- A true 13th salary can never be reclaimed — it is earned remuneration; a repayment clause on it is invalid.
Pro rata on exit
If your payment has remuneration character (13th salary or Mischcharakter), you earn it month by month. Leaving on 30 September means 9/12 of the annual amount — regardless of clauses demanding employment at year-end. Watch two traps: the due date (contracts often make the pro-rata portion due with the final payroll or at the regular November date), and the Ausschlussfrist — the three-month forfeiture window typically starts at the due date, not at year-end. For bonus components that pay out after you have already left, see bonus after termination.
Worked example
Software engineer in Bonn, gross salary €5,500 per month, contract promises „a 13th monthly salary, payable with the November salary”. She resigns effective 30 September to join another company. The employer refuses any payment, pointing to a contract clause: „Entitlement exists only if the employment relationship is unterminated on 1 December.”
- Character: a 13th salary is pure remuneration — earned pro rata.
- Cut-off clause: invalid under the BAG’s case law, because it strips earned remuneration.
- Claim: 9/12 × €5,500 = €4,125 gross.
- Deadline management: her contract contains a three-month Ausschlussfrist in text form. We assert the claim in writing in October (due date at exit is arguable, so we file early), the employer refuses, and we sue at the Arbeitsgericht. Outcome in comparable cases: full payment or a settlement close to it — the legal position is clear, and employers rarely let a losing Sonderzahlung case go to judgment.
Had the same employee received „Weihnachtsgratifikation” of €500 paid unconditionally in each of the last four years with no contract clause at all, the result would be similar via betriebliche Übung — €375 pro rata, or the full €500 if payment conditions had crystallised unconditionally.
Frequently asked questions
My employer paid Christmas bonus three years running, but this year announced „no bonus due to the economic situation”. Legal?
If the three payments were unconditional, a betriebliche Übung binds the employer — economic difficulty alone does not dissolve it. The employer would need a valid contractual reservation, a Änderungsvertrag, or (in extreme cases) a Änderungskündigung. A mere announcement is none of these. Assert the claim in writing before your forfeiture clause runs.
The payslip says „freiwillige Sonderzahlung” every year. Does that kill my claim?
Usually not by itself. A payslip note is not a contract term, and even contractual voluntariness clauses are frequently invalid — particularly combined „voluntary and revocable” wording, or where the payment remunerates work. Have the exact wording checked before you give up.
I was on long-term sick leave part of the year. Can the bonus be reduced?
Only if a valid agreement says so. § 4a EFZG permits agreed reductions for sickness absence, capped at one quarter of a day’s pay per sick day. Without such an agreement, no reduction. Parental-leave months may be treated differently for loyalty-character payments depending on the clause — worth an individual check.
Do I receive the 13th salary during the notice period or garden leave?
Yes. Notice period and garden leave are ordinary employment time — remuneration-character payments continue to accrue until the termination date, including pro rata for the exit year.
I received my Weihnachtsgeld in November and quit effective 31 January. Must I repay it?
Only if there is a valid repayment clause and the payment has loyalty character. For amounts up to one month’s salary, binding until 31 March of the following year is the maximum the case law tolerates — so a January exit can trigger repayment under a properly drafted clause. If the payment is in truth a 13th salary, repayment cannot be demanded at all.
How long do I have to claim an unpaid bonus?
Check your contract and any applicable Tarifvertrag for an Ausschlussfrist — typically three months from the due date, sometimes with a second stage requiring a court claim. Miss it and even a rock-solid claim dies. The absolute outer limit is the three-year limitation period.
