In principle, the country where you work is responsible for health insurance, otherwise the country where you live; nationality does not count.
For Swedish social insurance, you count as resident in Sweden if you come to the country and are expected to stay longer than a year, unless there are special reasons against it. If you move to Sweden and plan to stay at least a year, you usually report the move to the tax agency (Skatteverket), are entered in the population register and receive a personal identity number (Personnummer); if you stay for a shorter time, you are not registered.
If you are registered in Sweden, according to the Försäkringskassan (Swedish Social Insurance Agency) you are entitled to medical and dental care on the same terms as other residents and pay the usual patient fee in the public system.
The Försäkringskassan has a task of its own. If you move to Sweden without children, you can report details to the Försäkringskassan, for example to apply for an EHIC or a benefit; the Försäkringskassan then checks whether you are insured in Sweden.
| Situation | What the sources say | What you clarify |
|---|
| Employees and self-employed | If you are employed or self-employed in Sweden, you can stay for more than three months without a residence permit, and the law does not name health insurance as a condition. | Ask Skatteverket whether the planned length of stay is enough for registration. |
|---|
| Seconded employees | If an employer from an EU state posts you to Sweden (secondment), you usually remain socially insured under the law of the sending state; the certificate for this is the A1. | Ask your employer whether an A1 is being applied for. |
|---|
| Investors without their own activity | Without work in Sweden, the route for people who do not work applies. For people who do not work, the Swedish Aliens Act requires sufficient resources and comprehensive health insurance that is valid in Sweden. Whether a shareholding counts as self-employment is assessed by Skatteverket case by case. | Ask Skatteverket how it classifies your situation. |
|---|
| Private means and pensioners | An EEA citizen who does not work may stay longer than three months if they have sufficient resources for themselves and their family and hold comprehensive health insurance that is valid in Sweden. If you receive a pension from another EU country, you apply for the S1 there and have it registered in your country of residence with the competent health insurance institution; it certifies your entitlement to care in the country of residence. | Ask your pension insurer and your Krankenkasse (German health insurance fund) whether an S1 is an option for you. |
|---|
| Families | Spouses and partners, children under 21 and dependent relatives of an EEA citizen receive a right of residence in Sweden that depends on the EEA citizen’s right of residence. | Ask your Krankenkasse (German health insurance fund) about family insurance and the S1. |
