How the 2024 agreement works
Old cross-border workers (already commuting before 17 July 2023 and resident in the 20 km band, like Arosio) stay taxed exclusively in Switzerland: they pay only the Swiss withholding tax and no Italian IRPEF on their frontier income.
New cross-border workers face concurrent taxation: Switzerland withholds tax at source and Italy taxes the same income while granting a credit for the Swiss tax, adding regional and municipal surtaxes. In Arosio the municipal surtax is 0.55%, about €234 per year in the sample scenario.
