Moving to Aargau: what expats should know
Aargau sits between Zurich and Basel and works mostly as a commuter belt for both. The local economy is industrial — engineering, energy, mechanical — and the canton trades international intensity and prestige for materially lower rents. The value here is the rail position, not the canton itself.
Quick overview
- Language: German
- Main cities: Aarau, Baden, Wettingen
- Tax level: Lower-to-middle (commune-driven) (relative to Switzerland)
- Cost of living: Medium (below Zurich and Basel)
- International profile: Low-to-medium
Why expats choose Aargau
- Located between Zurich and Basel with frequent fast trains to both — the canton's main strategic asset.
- Lower rents than either neighbouring city — at the cost of a less international and lower-prestige environment.
- Strong industrial base (ABB, Axpo, mechanical engineering) — narrower than Zurich's economy and overwhelmingly German-speaking.
- Smaller communes and good schools — combined with a less developed international family infrastructure than Zurich or Basel.
Housing
Baden, Aarau, and Wettingen are the pressure zones, with Wettingen pulled higher by the Zurich commute. Outlying communes are clearly cheaper. Family houses and four-room flats are widely available outside the main centres.
Cost of living
Visibly below Zurich and Basel for rent, dining, and childcare. Standard Swiss patterns elsewhere. The cost gap is the canton's main quantitative argument.
Work & economy
Heavy on engineering and energy — ABB and Axpo anchor a wider industrial base. Many residents commute to Zurich or Basel for finance, tech, and corporate roles. German is the working language outside large multinationals.
Lifestyle
Practical small-town and suburban Switzerland — rivers, vineyards, family routine, easy weekend trips to either neighbouring city. Less international atmosphere; less cultural depth than Zurich or Basel themselves.
Administration basics
Most steps in Aargau 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
Aargau's cantonal tax sits in the lower-to-middle Swiss range — generally below Zurich at most brackets. Commune choice along the Zurich/Basel rail spine matters more than the cantonal average suggests.
Who Aargau is best for
- Daily commuters to Zurich or Basel prioritising lower rent over short commute.
- Engineering and energy-sector professionals at ABB, Axpo, or related employers.
- Households seeking lower cost near a major employer hub, with at least one car-or-train-flexible earner.
- Long-term settlers planning to buy in the Mittelland and accepting a less international environment.
- Couples with one Zurich and one Basel job — Aargau is the geographic compromise.
When you may need support
If you are choosing Aargau over Zurich or Basel for cost reasons, the commune choice along the rail spine drives the actual saving. Pick the wrong one and the rent gap closes while the commute lengthens.
