Christmas bonus in Germany: why so much is deducted (2026)
A Christmas bonus (Weihnachtsgeld) or 13th month salary (13. Monatsgehalt) is fully taxed and subject to social insurance in Germany, but it is calculated differently from your monthly pay. Income tax on it is based on your yearly pay, so a much larger share usually goes than from a normal month. That is normally not an error.

Are you entitled to one?
There is no legal right. It comes from a collective agreement (Tarifvertrag; in the public sector, for example, the annual special payment under TVöD, paid with November salary), your employment contract, a works agreement, or established company practice (betriebliche Übung): if your employer pays it several years in a row without a clear reservation that it is voluntary, you can acquire a right to it. Whether you get a pro-rated amount when you join or leave during the year depends on the purpose of the payment and its exact wording. A 13th month paid purely for your work is usually pro-rated; a Christmas bonus that rewards loyalty can be tied to a cut-off date. Clauses requiring you to pay it back are valid only within narrow limits.
Income tax: why the deduction looks so high
The bonus is a one-off payment (sonstiger Bezug). Your employer estimates your yearly pay without it, works out the annual income tax on that, then again with the bonus included. The difference is the tax on the bonus. Because the tax scale is progressive, the bonus is taxed at your marginal rate, the rate on the top euros of your income. Your monthly pay only carries the average rate, which includes the tax-free allowance. Roughly, tax class I, no children, no church tax, 4,000 EUR gross a month: a normal month costs about 500 EUR in income tax, around 13%. On a 4,000 EUR bonus it is just under 1,000 EUR, about a quarter, plus around 870 EUR of social insurance.
Social insurance and the contribution ceiling
The bonus counts as a one-off payment (Einmalzahlung) and is subject to all four social insurance contributions at the usual rates. Contributions only apply up to the pro-rated annual ceiling (anteilige Jahres-Beitragsbemessungsgrenze): the ceiling for the months you have worked for this employer this year, up to and including the payment month, minus the pay already charged. In 2026 the ceiling is 69,750 EUR a year for health and care insurance and 101,400 EUR for pension and unemployment insurance. Example: at 5,500 EUR a month since January, 66,000 EUR has been charged by December. Health and care contributions then apply to only 3,750 EUR of the bonus, pension contributions to all of it. The March rule (Märzklausel) only affects payments made from January to March.
Solidarity surcharge and church tax
Church tax (Kirchensteuer) on the bonus is 8% of the income tax in Bavaria and Baden-Württemberg and 9% elsewhere, and only applies if you belong to a church that levies it. The solidarity surcharge (Soli) is charged on the bonus only if your annual income tax including the bonus is above the exemption limit: 20,350 EUR in 2026 for tax classes I, II, IV, V and VI, and double that in class III. For most employees the Soli line stays empty in December too. If an amount appears there while your income is well below that level, ask payroll.
What to check on your payslip
The amount matches your collective agreement or contract, pro-rated for part-time work or a mid-year start if the rules say so; the bonus is on its own line as a one-off payment (Einmalbezug or sonstiger Bezug); your tax class and child allowances are right; on a high salary, health and care contributions stop at the pro-rated ceiling; no Soli on an ordinary income. Income tax withheld in excess, for example because your yearly pay was estimated too high, comes back with your tax return. Payslop checks this for free.

Questions people ask
Will I get the tax on my bonus back?
Usually not all of it, because the annual-pay method normally lands close to your real tax. A refund is most likely if your yearly pay was overestimated, for example after joining mid-year, or if your work expenses exceed the 1,230 EUR flat allowance.
Is it worth moving the bonus to January?
Rarely. The tax then depends on the new year's income, which is similar if your salary stays the same. Whether the payment can be moved at all depends on your contract or collective agreement.
Is a Christmas bonus the same as a 13th month salary?
For tax and social insurance they are treated the same. Under employment law the difference can matter: a 13th month usually pays for your work and is pro-rated, while a Christmas bonus can be tied to loyalty or a cut-off date.
