Seasonal vs Annual Work Naspi Cross Border Workers (cross-border guide)

Last updated: July 2026

For a new cross-border worker (hired from 17 July 2023 onward) residing within 20 km of the border, the Swiss salary is taxed concurrently: Switzerland withholds source tax on 80% of income, Italy taxes total income via IRPEF (after a flat €10,000 exemption) and grants a proportional tax credit for what was already paid in Switzerland.

NASpI is income assimilated to employment income: it is added to the frontaliere income in the same IRPEF return, does not benefit from the €10,000 exemption (which applies only to foreign employment income), and is therefore taxed together with the rest on the same progressive base.

NASpI duration depends on weeks contributed in the last 4 years, net of weeks already "used" by a prior NASpI in the same period: if you already received NASpI months recently, your residual entitlement for a new unemployment event is lower — always verify with INPS before planning a seasonal scenario.

A voluntary contribution to a supplementary pension fund reduces the IRPEF taxable base up to an annual cap (Art. 8 Legislative Decree 252/2005), but it is still money leaving your pocket this year: the tax saving is always lower than the amount contributed, and the benefit should be judged over the long term (retirement savings), not on the immediate net.
