Context
In brief
- Withholding tax levied only in Switzerland
- Exemptions: 7,500 euros (old) or 10,000 euros (new)
- New Agreement in force since January 1, 2024
- Tax credit in Italy to avoid double taxation
Key facts
Frontalieri Agreement: signed 12/23/2020, in force 01/01/2024 Italian Ratification: Law 83 of 06/13/2023 Double Taxation Convention: 12/09/1976 Exemption for New Frontalieri: 10,000 euros Exemption for Old Frontalieri: 7,500 euros IRPEF 23%: up to 28,000 euros
The tax framework for those who work in Switzerland and reside in Italy is governed by precise rules, with particular attention to those who exceed a distance of 20 km. The withholding tax on employment income is levied exclusively in Switzerland. To prevent the worker from paying twice on the same income, Italy applies a tax credit through the CE section of the 730 tax return.
The new tax regime
The New Frontalieri Agreement, signed on December 23, 2020, and ratified in Italy with Law 83 of June 13, 2023, entered into force on January 1, 2024. This text defines the basis of current taxation, which will continue through 2026. Since Switzerland is not a member of the EU or EEA, it relies on the Double Taxation Convention signed on December 9, 1976, to coordinate tax flows with the Italian State.
The administration of these taxes is divided between the AFC/ESTV (Federal Tax Administration) at the federal level and the cantonal tax administrations. It is important to clarify that entities such as UFAS or BFS have no power to set tax rates, as they deal respectively with social security and statistics. Workers who acquired frontier worker status before July 17, 2023, benefit from a transitional regime valid until 2033, with an exemption of 7,500 euros, while new entries have an exemption of 10,000 euros.
Operational details
Practical Analysis and Tax Scenarios
The distinction between cross-border workers residing at different distances from the border, particularly the 20 km limit, influences the perception of the overall tax burden. Although withholding tax is collected in Switzerland, the final calculation in Italy depends on IRPEF rates: 23% for income up to 28,000 euros, 35% between 28,001 and 50,000 euros, and 43% over 50,000 euros.
Hypothetical Taxation Scenarios
To understand the impact, let us consider two scenarios based on the provided exemptions. In a first hypothetical scenario, an 'old' cross-border worker (active before July 17, 2023) applies an exemption of 7,500 euros to their income before calculating the tax impact in Italy. In a second scenario, a 'new' cross-border worker can benefit from the higher exemption of 10,000 euros.
The analysis of the net amount also depends on mandatory Swiss contributions. The payslip shows AVS/AI/IPG deductions at 5.3% borne by the employee, unemployment insurance AD/AC at 1.1% (with a ceiling of 148,200 CHF), and LAINF between 0.7% and 1.5%. To these is added the LPP, which varies between 7% and 18% depending on the age group, starting from age 25.
The comparison between the two regimes shows how the 2024-2033 transitional regime protects long-term workers, while new agreements seek to standardize exemption thresholds. Those residing beyond 20 km must carefully monitor the tax credit to avoid reporting errors that could lead to penalties from the Agenzia delle Entrate. To optimize the calculation of your net salary, it is useful to use a calculator updated with the 2026 rates.

Key points
Operational Guide and Steps to Follow
To correctly manage taxation in 2026, especially for those residing beyond 20 km, it is necessary to follow a rigorous reporting procedure. Managing the flows between Switzerland and Italy requires precision in the documents submitted to the Agenzia delle Entrate and the MEF.
Tax Declaration Checklist
1. Retrieval of the Swiss income certificate: a fundamental document issued by the cantonal tax administration. 2. Verification of the applicable exemption: determine whether you fall under the 'old cross-border commuters' (7,500 euro exemption) or the 'new' ones (10,000 euro exemption). 3. Completion of the CE section of the 730 form: entry of taxes paid in Switzerland to request the tax credit and neutralize double taxation. 4. Check of social security contributions: verification of AVS and LPP quotas paid for possible coordination with INPS.
In addition to taxes, the cross-border worker must manage the LAMal health insurance. Holders of a G permit have a right of option for insurance; for adults, the provided deductibles vary from 300 to 2,500 CHF. It is essential that this choice is consistent with one's health situation and budget.

Frequently Asked Questions
- Where is the frontier tax paid at source?
- Income tax at source is only withheld in Switzerland. Italy does not collect the tax at source, but avoids double taxation through the application of a tax credit that the worker requests in the EC framework of their tax return (form 730).
- What is the difference in deductibles between old and new frontier workers?
- Old frontier workers, i.e. those who already had this status before 17 July 2023, benefit from a transitional regime (valid from 2024 to 2033) with an exemption of 7,500 euros. The new frontier workers, on the other hand, are entitled to a deductible of 10,000 euros.
- What are the IRPEF rates applicable in 2026?
- The expected Italian personal income tax rates are: 23% for the income bracket up to 28,000 euros, 35% for the bracket between 28,001 and 50,000 euros, and 43% for incomes exceeding 50,000 euros.
