To avoid the same income being taxed twice, Italy grants a tax credit that the taxpayer must apply for by filling in the EC framework of the tax return (form 730). This mechanism is based on the Convention for the elimination of double taxation between Italy and Switzerland, signed on 9 December 1976, recalling that Switzerland is not a member of the European Union or the European Economic Area. ### The regulatory framework and the Frontier Agreement The current system is governed by the New Frontier Agreement, signed on 23 December 2020 and entered into force on 1 January 2024. In Italy, this agreement was ratified by Law 83 of 13 June 2023. The legislation introduces a fundamental distinction between workers based on the date of commencement of cross-border activity.

Operational details

Practical analysis of the tax credit The application of the tax credit requires a precise analysis of residence and distance from the workplace, with particular attention to the 20 km threshold. Although the tax is paid in Switzerland, the income must be declared in Italy. The tax credit serves to compensate the IRPEF due in Italy with the taxes already paid abroad.

Hypothetical calculation scenarios To understand the fiscal impact, let's consider two scenarios based on the expected exemptions. In a first hypothetical scenario, a worker who falls under the 'old cross-border workers' enjoys an exemption of €7,500; the part of income exceeding this threshold is added to other Italian incomes and taxed according to the IRPEF rates, then subtracting the tax credit for the Swiss taxes paid.

In a second scenario, a 'new cross-border worker' benefits from a higher exemption of €10,000. This results in a lower taxable base compared to the previous case, potentially reducing the net tax due to the Italian Revenue Agency. In both cases, it is essential to verify that the social security contributions have been correctly deducted. The standard Swiss contributions include AVS/AI/IPG at 5.3% to the employee's charge, AD/AC at 1.1% (with a ceiling of 148,200 CHF) and LPP, which varies between 7% and 18% depending on the age group starting from 25 years.

Key points

Operational guide for the 2026 tax declaration To correctly obtain the tax credit in 2026, the frontier worker must follow a rigorous procedure for collecting documents and completing the tax return. The objective is to align the Swiss payslip data with the requirements of the Italian Ministry of Finance (MEF) and the Revenue Agency.

Checklist for completion

1. Recovery of the Swiss income certificate: the official document certifying gross income and taxes actually paid in Switzerland is required. 2. Calculation of the allowance: identify whether you belong to the 'old frontier workers' category (exemption of 7,500 euros) or 'new frontier workers' (allowance of 10,000 euros). 3. Currency conversion: convert values from CHF to EUR using the official exchange rates for the tax year in question. 4. Completion of Box CE: insert data into the 730 model to request the tax credit and neutralize double taxation.

Management of deductions and charges

In addition to the tax credit, the taxpayer must consider deductions for charges. A key element is the LAMal health insurance. Frontier workers with a G permit have an option right and must manage the adult allowances, which vary from 300 to 2,500 CHF. These costs, together with the pension contributions paid to bodies such as INPS or AVS, influence the final calculation of the tax burden.

To avoid errors in the tax return declaration, it is advisable to map every item on the Swiss payslip, including deductions for accident insurance LAINF and LPP contributions. An incorrect completion of Box CE can lead to penalties or loss of the tax credit.
