The New Cross-Border Workers 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 cross-border workers. Old cross-border workers remain taxed only in Switzerland (Art. 9 of the 2020 Agreement). For Article 9 of the Agreement, “old frontier workers” are people who met the tax requirements and worked in Graubünden, Ticino or Valais on 17 July 2023 or during the period from 31 December 2018 through 17 July 2023. Article 9 keeps covered employment income taxable exclusively at source in Switzerland; other workers follow the ordinary regime, with ordinary taxation in Italy, a credit for Swiss tax and Swiss withholding at 80% of the ordinary rates. The €10,000 figure in Article 4 of Italian Law No. 83/2023 is only the income limit referred to in Article 1(175) of Law No. 147/2013; it is not a general allowance for new frontier workers. Sources: ESTV factsheet (Italian) · Agreement, Art. 9 · Law No. 83/2023, Art. 4. Italy avoids double taxation through the tax credit to be indicated in section CE of Form 730.

The Convention for the Avoidance of Double Taxation between Italy and Switzerland remains the one signed on 9 March 1976. Switzerland confirms that it is neither a member of the European Union nor of the European Economic Area (EEA), as explicitly indicated in the source. This status affects tax and administrative relations with neighboring countries.

With regard to Swiss social contributions, the source specifies that AVS/AI/IPG is 5,3% payable by the employee. AD/AC (unemployment and insolvency insurance) is 1,1% with a maximum annual salary ceiling of CHF 148'200. LAINF (Accident Insurance Act) ranges between 0,7% and 1,5% depending on the sector of activity and occupational risk. LPP (occupational pension provision) provides for contributions ranging between 7% and 18%, calculated based on the worker's age bracket starting at age 25.

Personal income tax (IRPEF) rates in Italy are structured by brackets: 23% up to €28'000 of taxable income, 33% between €28'001 and €50'000, and 43% above €50'000. These values are in force from the 2026 tax period (Law 199/2025, Art. 1, para. 3) and are the reference for calculating the taxes owed in Italy by cross-border workers.

The entities and acronyms officially recognized in the source include SECO (State Secretariat for Economic Affairs), SEM (State Secretariat for Migration), USTAT (Statistical Office), UFSP/BAG (Federal Office of Public Health/Federal Office of Insurance), SUVA (Swiss Accident Insurance Institute), INPS, Revenue Agency, MEF (Ministry of Economy and Finance), BFS (Federal Statistical Office) and AFC/ESTV (Federal Tax Administration). These institutions are responsible for administering and applying tax and contribution rules in Switzerland.

It is important to emphasize that tax rates, both withholding tax rates and federal and cantonal rates, are established exclusively by federal and cantonal laws. Their administration is entrusted to the AFC/ESTV at the federal level and to the cantonal tax administrations at the cantonal level. UFAS (now part of UFSP) and BFS have no role in setting the rates: the former deals with social security, while the latter is limited to collecting and publishing statistical data.

Finally, LAMal (Health Insurance Act) is not a health tax but Switzerland's mandatory health insurance. Cross-border workers with a G permit have the right to choose between Swiss LAMal and Italian healthcare. The annual deductible for adults ranges from CHF 300 to CHF 2'500, depending on the insurance model chosen.

Operational details

Key facts

• What: Practical application of Swiss contribution rates
• When: Calculations based on data currently in force from the source
• Where: Switzerland, valid for all cantons including Basel
• Who: Employees with the cantonal average salary
• Amount: Examples of calculating 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 analyze how they apply to a hypothetical average salary in the canton of Basel. Considering a gross annual income of CHF 100'000, the mandatory contributions payable by the employee are calculated as follows: AVS/AI/IPG at 5,3% amounts to CHF 5'300 per year. AD/AC at 1,1% applies to the entire amount because it is below the cap of CHF 148'200, resulting in CHF 1'100. LAINF, in its average band of 1,1%, adds another CHF 1'100. For LPP, assuming an average rate of 12,5% (within the 7–18% range by age group), the contribution is CHF 12'500.

The total social contributions payable by the worker therefore amount to CHF 20'000 on a gross income of CHF 100'000, equivalent to 20% of the salary. This percentage remains unchanged regardless of the canton of employment, since AVS/AI/IPG, AD/AC and LAINF are regulated at federal level, while LPP presents slight cantonal variations in administration but not in the minimum and maximum legal rates reported by the source.

In the canton of Basel, where the pharmaceutical and chemical sector accounts for a significant share of employment, average salaries tend to exceed the national average. However, the contribution rates reported in the source apply uniformly: an increase in gross salary entails a proportional increase in contributions, except that AD/AC ceases to be payable above the cap of CHF 148'200. For example, with a salary of CHF 180'000, AD/AC remains fixed at CHF 1'628,20 (1,1% of CHF 148'200), while AVS/AI/IPG rises to CHF 9'540 (5,3% of CHF 180'000).

This structure has direct implications for available net income. A cross-border worker who lives in Italy and works in Basel must consider that, in addition to Swiss withholding taxes, they will have to pay IRPEF in Italy according to the rates in force (23%, 33%, 43%; Law 199/2025, art. 1, para. 3), but may claim a tax credit to avoid double taxation. The credit is calculated on the Swiss tax paid and recognized in the Italian tax return via section CE of Form 730.

The distinction between old and new cross-border workers remains relevant for calculating the tax exemption. Old cross-border workers remain taxed only in Switzerland (Art. 9 of the 2020 Agreement). The €10,000 threshold in Article 4 of Italian Law No. 83/2023 applies exclusively to employment income earned continuously and exclusively by Italian residents in a foreign border area or neighbouring country, as referred to in Article 1(175) of Law No. 147/2013; it is neither a general allowance nor an exemption from Swiss withholding tax. Both groups must nevertheless comply with filing obligations in both countries.

Finally, Switzerland's membership of the EEA is excluded by the source, which means that cross-border workers do not benefit from the same administrative simplifications provided for EU/EEA workers. This aspect affects institutional coordination procedures between Italy and Switzerland, which must take place through the instruments of the 1976 convention and the new 2020 agreement, administered by SEM, SECO and AFC/ESTV according to their respective areas of responsibility.

Key points

Key facts

• What: Operating procedures for cross-border workers in Switzerland
• When: Deadlines and requirements according to source
• Where: Cantonal tax offices and Italian authorities
• Who: Italian cross-border workers in Switzerland, public and private sectors
• The €10,000 limit is not a general allowance: Article 4 of Italian Law No. 83/2023 applies it only to the income referred to in Article 1(175) of Law No. 147/2013.

To correctly fulfill the obligations arising from the New Cross-Border Workers Agreement, workers must follow a well-defined procedure. The €10,000 limit is not a general allowance: Article 4 of Italian Law No. 83/2023 applies it only to the income referred to in Article 1(175) of Law No. 147/2013. This distinction is essential for calculating taxable income in the Italian tax return.

The second step concerns collecting the necessary documentation. Required documents include: the Swiss salary certificate issued by the employer, annual payslips showing 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 bracket), as well as proof of payment of Swiss withholding tax. These documents are essential for correctly completing section CE of the Italian 730 form.

The third step is filing the tax return in Italy. Section CE must include: employment income earned in Switzerland, Swiss tax already paid at source, and Swiss social security contributions. The Italian system recognizes a tax credit equal to the Swiss tax paid, thereby avoiding double taxation as provided for by the 1976 convention and the new 2020 agreement.

In Switzerland, any refunds of withholding tax must be requested directly from the competent cantonal tax administration for the place of employment. In Basel, this office is the Tax Administration of the Canton of Basel-Landschaft or Basel-Stadt, depending on the municipality of employment. The request can be submitted online through the official AFC/ESTV portal or by visiting the counter with the required documentation.

As regards health insurance, cross-border workers with a G permit must decide within three months of starting work whether to opt for Swiss LAMal or remain in the Italian healthcare system. The choice is irrevocable except in the event of changes in employment or residence. The LAMal deductible ranges from CHF 300 to CHF 2'500 for adults, directly affecting the annual cost of insurance.

Finally, it is advisable to check annually for any updates to the rates reported in the source. Although AVS/AI/IPG (5,3%), AD/AC (1,1%) and the cap limits (CHF 148'200) are stable in the medium term, LAINF and LPP may undergo cantonal or federal adjustments. Official updates are published by SECO, SEM and AFC/ESTV, and are also reported in the USTAT/BFS bulletin regarding statistics on the labor market and average salaries by profession in Switzerland, including those specific to the canton of Basel in 2026.

Article 1(237–238) of Italian Law No. 213/2023 does not apply indiscriminately to all cross-border workers. It covers: (a) Italian residents who work and stay in Switzerland and use the Italian SSN; (b) frontier workers under Article 9(1) of the Italy–Switzerland Agreement whose income is taxable only in Switzerland and who exercised the legal right to choose health insurance; and (c) dependants of those two categories. Paragraph 238 sets a progressive 3–6% share of net Swiss salary, with a €30 minimum and an ordinary €200 maximum for each month worked from 2024. The cap may be doubled in cases of omitted payment or omitted communication specified in Article 1(100) of Law No. 207/2024. The Region of residence sets the rates and procedure each year.
