Frontalier à moins ou plus de 20 km: ce qui change vraiment

With the 2024 Italy-Switzerland tax agreement, the distance from the Swiss border has become a determining factor for new cross-border workers. The 20 km threshold draws a clear line between two different tax treatments.

Cross-border workers within 20 km

New cross-border workers residing within 20 km of the Swiss border benefit from the standard regime: 80% withholding tax in Switzerland and concurrent IRPEF taxation in Italy with EUR 10,000 allowance. With CHF 80,000 gross, annual net is approximately CHF 46'948.

Cross-border workers over 20 km

Those residing over 20 km from the border are not technically "cross-border workers" for tax purposes. Italy taxes the full income without allowance. With CHF 80,000 gross and residence over 20 km, net drops to approximately CHF 46'948.

FAQ

How is the 20 km distance measured?
The distance is measured as the crow flies between the municipality of residence and the nearest Italy-Switzerland border, not by road.
Does the 20 km rule apply to old cross-border workers?
No, old cross-border workers (pre-2024) are not subject to the 20 km rule. It only applies to new cross-border workers.
