Key facts

The New Frontier Agreement between Italy and Switzerland was signed on 23 December 2020 and entered into force on 1 January 2024, as established by the source. This agreement replaces the previous regime and introduces new provisions for frontier workers. For border workers already active before 17 July 2023, there is an exemption of €7,500 with a transitional regime valid until 2033. For new frontier workers, those who started their activity after that date, the deductible is set at €10,000. Italy avoids double taxation through the tax credit to be indicated in the EC framework of model 730.

The Double Taxation Convention between Italy and Switzerland remains the one signed on 9 December 1976. Switzerland confirms that it is not a member of the European Union or the European Economic Area (EEA), as explicitly stated in the source. This status affects fiscal and administrative relations with neighbouring countries.

Key facts

• What: Practical application of Swiss tax rates
• When: Calculations based on current data from the source
• Where: Switzerland, valid for all cantons including Basel
• Who: Employees with average cantonal salary
• Amount: Examples of calculation of AVS/AI/IPG contributions 5.3%, AD/AC 1.1%

To understand the practical impact of the rates reported in the source, it is useful to analyse how they apply to a hypothetical average salary in the canton of Basel. Considering a gross annual income of CHF 100,000, the employee's mandatory contributions are calculated as follows: the AVS/AI/IPG at 5.3% amounts to CHF5,300 per year. The AD/AC at 1.1% applies to the entire amount as it is lower than the cap of CHF 148'200, resulting in CHF 1'100. LAINF, in its 1.1% mid-range, adds another CHF 1'100. For LPP, assuming an average rate of 12.5% (within the range 7–18% by age group), the contribution is CHF 12,500.

The total social contributions borne by the worker therefore amount to CHF 20,000 on a gross income of CHF100,000, equivalent to 20% of the salary. This percentage remains unchanged regardless of the working canton, since AVS/AI/IPG, AD/AC and LAINF are regulated at the federal level, while the LPP has slight cantonal variations in management but not in the minimum and maximum legal rates reported by the source.

Key facts

• What: Operating procedures for border workers in Switzerland
• When: Deadlines and obligations according to source
• Where: Cantonal offices of contributions and Italian administrations
• Who: Italian border guards in Switzerland, public and private sector
• Amount: Deductible €7,500 (old), €10,000 (new)

In order to properly fulfil the obligations deriving from the New Frontier Agreement, workers must follow a well-defined procedure. The first step is to verify your date of commencement of activity in Switzerland: if before 17 July 2023, the regime applies for old border workers with a deductible of €7,500; if later, that for new border workers with a deductible of €10,000. This distinction is fundamental for the calculation of the taxable amount in the Italian declaration.

The second step concerns the collection of the necessary documentation. You need: the Swiss salary certificate issued by the employer, the annual pay slips that show the AVS/AI/IPG contributions (5.3%), AD/AC (1.1% with cap CHF 148'200), LAINF (0.7-1.5%) and LPP (7–18% by age group), as well as the certification of the payment of the tax at the Swiss source. These documents are essential to correctly fill in the CE framework of the Italian model 730.

The third step is the presentation of the tax return in Italy. The following must be indicated in the EC framework: the employee income produced in Switzerland, the tax
