Answer
The Italy-Switzerland Agreement of 23/12/2020, in force since 17/07/2023, applicable from 1 January 2024 and ratified by Italian Law 83/2023, sets out two regimes: 'old' cross-border workers (Italian residents who meet art. 9, having worked as cross-border workers in the cantons of GR, TI or VS on 17/07/2023 or between 31/12/2018 and that date) remain taxed only at source in Switzerland, with a 40% compensation to Italy through tax year 2033; '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.
