What to check in your situation

To correctly assess the tax impact of working in Switzerland as a border worker, follow these practical steps based on the source information. First, confirm your category: if you started working in Switzerland after July 17, 2023, you are a 'new border worker' with a CHF 10,000 exemption; Old cross-border workers remain taxed only in Switzerland (Art. 9 of the 2020 Agreement). This distinction is crucial as it directly affects the taxable income subject to Swiss withholding tax. Next, obtain your contribution details from your Swiss pay slip. Check that they include: AVS/AI/IPG at 5.3% of the total salary, AD/AC at 1.1% (with application of the CHF 148,200 cap if your annual income exceeds this threshold), LAINF at the specific percentage of your sector (0.7% to 1.5%), and LPP according to your age bracket (7% to 18%). These values are indicated by the source as standard contributions withheld in Switzerland. Finally, compare your net Swiss withholding tax with what you would pay in Italy applying the IRPEF tax brackets (23% up to CHF 28,000, 33% from CHF 28,001 to CHF 50,000, 43% over CHF 50,000) and taking into account the tax credit recognized by the Revenue Agency to avoid double taxation, as provided for by the March 9, 1976 Convention and the New Border Workers Agreement.
