Two countries, one family, one tax bill that adds up correctly.
Grenzgänger status, double-taxation treaties, inheritance and gifts, marriage, divorce, succession — life across a border multiplies the tax questions. We hand-match you to advisors who handle both sides fluently.
Where borders create double work
A single mistake can mean the same income or asset is taxed twice.
Grenzgänger status
Cross-border commuters are taxed under specific rules that differ by neighbouring country and canton. The paperwork is exacting.
Double-taxation treaties
Switzerland’s treaties decide which country taxes what. Applied correctly, they prevent double taxation — applied wrongly, they cause it.
Inheritance & gifts
Cantonal rules vary, and foreign assets bring a second regime. Planning ahead protects heirs from avoidable tax.
Marriage, divorce, succession
Joint assessment, separation, and passing wealth to the next generation each have material tax consequences.

Cross-border tax isn’t harder because of the maths — it’s harder because two systems disagree, and someone has to reconcile them.
