How to open a 3a account as a cross-border worker
For cross-border workers, the deduction must be requested through a withholding-tax recalculation by 31 March of the following year, provided at least 90% of taxable income is in Switzerland. In Ticino, since 2024 it is reserved for “old” cross-border workers: “new” cross-border workers have no Swiss or Italian deduction, so pillar 3a has no immediate tax advantage. It is mainly worthwhile for eligible “old” cross-border workers with a high withholding rate (>10%).
