A three-way tie for the top spot
If you are hunting for the absolute lowest taxes in Canton Solothurn, you have three identical choices at the top. Oberbuchsiten, Trimbach, and Oberdorf currently share the number one spot in our ranking.
For a single person earning 80,000 CHF, all three offer a 9.9% tax rate. A dual-income couple making 120,000 CHF pays 15.1%, and a family with an income of 150,000 CHF lands at 13.7%.

Directly behind the leaders are Herbetswil and Buchegg. They sit just a fraction of a percentage point higher.
A canton without extremes
The most important takeaway from the Solothurn data isn't who wins—it's how close the entire field is. The gap between the cheapest and most expensive municipality is noticeably small:
- Singles:
9.9%to10.6% - Couples:
15.1%to16.1% - Families:
13.7%to14.6%

This means Solothurn won't punish you with wild tax swings if you move a few towns over. It rewards careful comparison, but you don't need to sacrifice a great housing setup just to chase a 0.1% tax advantage.
How to use these numbers
This ranking is a great way to build a shortlist. If a town is in the top tier, you know your taxes are as optimized as they get in this canton. But once you narrow it down to a few places, focus on rent prices and your commute—those will likely impact your wallet far more than the municipal tax difference.
And as always: PLZHub is built for orientation. Before you sign a lease or buy property, run your exact income through the official tax calculator.
