Answer
The Italy-Switzerland Agreement of 23/12/2020, in force since 1 January 2024 and ratified by Italian Law 83/2023, sets out two regimes: 'old' cross-border workers (Italian residents already working in Switzerland before 17/07/2023) remain taxed only at source in Switzerland, with a rebate to Italian border municipalities; 'new' cross-border workers are taxed in both Switzerland and Italy, with a €10,000 exemption and a foreign-tax credit to avoid double taxation. For the full legal framework, calculation tables and practical 2026 scenarios, see the reference guide and practical overview below, plus the official Canton Ticino withholding-tax tables.
