Who Counts as a Grenzgänger
A Grenzgänger (cross-border commuter) lives in one country and works in another, returning home at least once a week. Tens of thousands do exactly this along Germany’s borders — living in Alsace, Vorarlberg, Basel or Salzburg while drawing a German salary. For health insurance the question is not where you sleep but which country’s social-security system your employment places you in, and EU coordination rules (Regulation 883/2004) usually put that in Germany, your country of work.
The core principle: you are generally insured where you work, not where you live. A German employment contract normally makes you subject to German health-insurance rules — including the choice between GKV and PKV if your income clears the threshold.
Where PKV Fits
If your German salary exceeds the compulsory-insurance limit (€77,400 gross a year in 2026) or you are self-employed, private health insurance is on the table just as it is for residents. The wrinkle is treatment location: as a commuter you will use doctors and hospitals on both sides of the border. A proper PKV Volltarif reimburses treatment across the EU at German rates, and worldwide within defined limits — so a French-resident commuter can be treated at home in France and claim back from a German insurer. Confirm the tariff’s European and worldwide clauses before you sign; they vary.
The Country-of-Residence Option
EU rules also let cross-border commuters register for benefits in their country of residence using the S1 mechanism, effectively receiving local statutory-style care paid for by the German system. That suits some commuters — but it is a statutory-benefits route, not private cover, and it does not deliver the private-patient advantages (specialist choice, single rooms, faster appointments) that draw people to PKV in the first place. Many higher earners keep German PKV precisely to avoid being funnelled into a neighbouring country’s standard system.
Practical Watch-Points
- Tax vs insurance are separate questions: your tax residence and your insurance country follow different rules — do not assume one settles the other
- Family members: check whether a non-working spouse and children are covered where you live or where you work; PKV insures each person individually, unlike GKV family insurance
- Switzerland is a special case: as a non-EU country with a bilateral agreement, Swiss-resident commuters have a formal right to opt between systems — take advice before defaulting
- Documentation: keep an insurer confirmation that your PKV is valid in your country of residence — you will need it for local providers and, sometimes, authorities
The Bottom Line
For a Grenzgänger, private health insurance behaves much as it does for any German employee — the difference is that your care straddles a border, so the tariff’s cross-border reimbursement terms matter more than usual. Establish which country’s system your work places you in, then choose a PKV tariff whose European and worldwide cover matches your real commuting life.
