Moving to Solothurn: what expats should know
Solothurn is a commuter and industrial canton between Basel, Bern, and Zurich. It is practical and visibly cheaper than its neighbours, but identity-thin: the canton is a transit and commuter belt rather than a destination, and the international scene is limited outside specific industrial employers.
Quick overview
- Language: German
- Main cities: Solothurn, Olten, Grenchen
- Tax level: Middle-to-higher (relative to Switzerland)
- Cost of living: Below Basel, Bern, and Zurich
- International profile: Low-to-medium
Why expats choose Solothurn
- Strategically positioned between Basel, Bern, and Zurich — useful precisely because the canton on its own is not a major employment hub.
- Visibly lower rents than any of the three neighbouring city cantons — combined with a less international and lower-prestige environment.
- Watch and precision industry in Grenchen (Swatch Group) — strong if you fit the sector, ordinary otherwise.
- Mid-tax positioning — neither low enough to draw high earners nor high enough to penalise; the canton lives or dies on the commute logic.
Housing
Solothurn city, Olten, and Grenchen are the active markets at clearly lower prices than Basel, Bern, or Zurich. Olten is the rail-hub pressure zone for Zurich/Bern commuters. Detached houses are widely available outside city centres.
Cost of living
Costs sit below all three neighbouring city cantons. Cross-shopping along the Aare and into Aargau is common.
Work & economy
Watchmaking in Grenchen (Swatch Group, ETA), industrial manufacturing, services, and a strong public sector. Corporate, finance, and tech roles are typically accessed by commuting to Basel, Bern, or Zurich. German is the working language outside the few international employers.
Lifestyle
Practical small-town and commuter Switzerland — Aare river setting, baroque old town in Solothurn, Jura on the southern edge. Cultural scale is local; international and English-speaking circles are thinner than in any of the three neighbouring cities.
Administration basics
Most steps in Solothurn follow the standard Swiss pattern: registration at your commune within 14 days of arrival, a residence permit issued through the canton, mandatory health insurance within three months of arrival, and a Swiss bank account once you have a confirmed address.
Tax situation
Solothurn's cantonal tax is in the middle-to-higher Swiss range — generally above Aargau, similar to Bern at most brackets. Commune choice along the Olten-Solothurn axis matters more than the headline.
Who Solothurn is best for
- Daily commuters to Basel, Bern, or Zurich prioritising lower rent over short commute.
- Watch and precision-industry employees in Grenchen at Swatch Group, ETA, or suppliers.
- Households with one Basel-area and one Zurich-area earner — Olten is the geographic compromise.
- Public-sector and industrial-employer staff with a confirmed local role.
- Cost-conscious households willing to trade prestige and international intensity for materially lower rent.
When you may need support
If you are choosing Solothurn over Basel, Bern, or Zurich for cost or commute reasons, the commune choice and the rail position decide the outcome — not the canton headline.
