A summer or part-time job abroad sounds like a good complement to a semester abroad, but it raises additional questions. If you work abroad, you need to know which social insurance rules apply, whether tax is due in the country of work or in Germany, and what happens to your health insurance. This guide sorts the main cases and shows which documents you should clarify before signing a contract.
Short answer: For a part-time job abroad, the place where you work is generally the starting point. Whether pay is taxed in Germany or abroad is usually governed by a double taxation agreement, where one exists. German law can continue to apply if a German employer sends you abroad (section 4 SGB IV). Last updated: October 2026.
The most important points
- The place of work is the starting point for social insurance. A job on site with a foreign employer generally follows the local system.
- Within the EU and the EEA, and with countries that have social security agreements with Germany, coordination rules apply to prevent double coverage.
- If your German employer sends you abroad, German law can continue to apply, but only for a temporary assignment (section 4 para. 1 SGB IV).
- For tax, your tax liability in Germany matters alongside the place of work. A double taxation agreement decides which country may tax.
- Before you leave, get written information from your health insurer and, if necessary, from the competent body for cases abroad.
Where do you work, and who is your employer?
Two questions decide how the job is classified: where the work takes place and who pays your wage. This gives three typical situations, which often overlap in practice. An overview helps before you sign a contract.
| Case | Social insurance | Tax | What to check |
|---|---|---|---|
| Job on site with a foreign employer | Generally the law of the place of work | Usually in the country of work, depending on the agreement | Contract, duration, proof of insurance |
| Job on site within the EU or EEA | EU coordination rules | Treaty rules per country | Certificates for health insurance |
| Posting by your German employer | German law may continue (section 4 SGB IV) | Depends on the individual case | Record the time limit in writing |
Posting under section 4 SGB IV: when German law stays in place
Under section 4 para. 1 SGB IV, the rules on compulsory insurance that presuppose employment also apply to people who are posted abroad during an existing employment relationship in Germany. The posting must be temporary, either because of the nature of the work or by advance contract. The provision therefore requires an existing employment in Germany. If you start a new job abroad, you usually do not fall under it.
For students this matters mainly if they stay with their German employer and only work abroad for a few weeks or months. How long a posting counts as temporary and which certificates are needed is assessed case by case. Your health insurer and the German pension insurance can give information.
Tax: avoiding double taxation
If you work abroad, the country of work may levy wage tax or a comparable tax. Whether Germany also taxes the income depends on whether you remain liable to tax in Germany and which agreement applies. Many countries have a double taxation agreement with Germany that divides taxing rights between the two states.
The German basic allowance is a useful reference: it is EUR 12,348 in 2026 (section 32a EStG, in German). It does not replace a proper check, because foreign income can be treated differently for German tax rates. Clarify with the tax office or a tax adviser before you start which returns are needed.
- Ask for the employment contract to state the place of work and the duration.
- Ask the tax office about your tax liability in Germany if you work abroad for longer than one semester.
- Keep all payslips and tax certificates from abroad.
Health insurance during a job abroad
Whether you stay insured in Germany during a part-time job abroad depends on your student status, the length of the stay and the type of employment. It also matters whether the job is in a country with which Germany has a social security agreement. A certificate of insurance cover, for postings within the EU often a form A1, protects you from paying contributions twice.
Many students only realise after the contract starts that they must be insured locally. Ask your health insurer before departure and get the answer in writing. Our guides on health insurance during a semester abroad and on insurance with a side job abroad (both in German) cover the questions you should clarify.
| Document | Purpose | Issued by |
|---|---|---|
| Proof of insurance from the health insurer | Shows cover abroad | Your health insurer |
| Form A1 (for postings within the EU) | Proof of membership in the German system | Competent health or pension insurer |
| Employment contract with duration and place of work | Basis for every check | Employer |
Pay and working conditions abroad
Which pay rules apply depends on the place of work and your contract. The German statutory minimum wage applies to work in Germany. For a job abroad, the local minimum wage, working time rules and leave entitlements apply. Compare hourly pay, deductions and accommodation before you accept, because a high gross wage says little if housing and contributions take most of it.
Frequently asked questions
Will I stay insured in Germany if I work abroad?
This can be the case, but it does not have to be. Your student status, the length of the stay and the type of work decide it. Clarify this with your health insurer before you leave.
Does the 70-day rule also apply to a summer job abroad?
The time limit in section 8 SGB IV refers to employment in Germany. For work abroad, the law of the country of work matters. Our guide on the 70-day rule (in German) explains the German side.
Do I have to pay tax abroad if I study in Germany?
Part of the income may be taxed abroad. Whether Germany also taxes it depends on the individual case and the agreement. The tax office or a tax adviser can give clarity.
Do I declare foreign income in my German tax return?
Usually yes, if you are liable to tax in Germany. Which details are needed depends on the agreement and the individual case.
