Key facts

• What: Living in Mesenzana and working in Ticino as a frontier worker
• Where: Mesenzana (province of Varese), border with Canton Ticino
• Who: Frontier workers with G or B permit
• Regulatory agreement: New Frontier Workers Agreement (in force since 1 January 2024)
• 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.
• Main crossings: Brogeda, Gaggiolo

Mesenzana, an Italian municipality in the province of Varese, attracts a growing number of frontier workers who work in the Canton of Ticino. A short distance from the Brogeda and Gaggiolo crossings, it offers quick access to the main Ticino economic centres — Lugano, Mendrisio, Chiasso — while maintaining a lower cost of living compared to the Swiss side.

Choosing to reside in Mesenzana while working in Ticino entails, however, a series of specific administrative and fiscal obligations. G permit frontier workers must register with INPS in Italy and declare employment income, while the withholding tax is retained in Switzerland by the employer. The new Italy‑Switzerland tax agreement — in force since 1 January 2024 — significantly affects these obligations. Before moving, one must assess the overall picture of rights and duties.

Geographic situation and access to crossings

Mesenzana lies a short distance from the Ticino border. The main accesses to Ticino are via the Brogeda crossing, the main road linking the Varese Valley to Ticino, and the Gaggiolo crossing. The strategic location enables reaching the main Ticino economic poles in reasonable time, although exact travel times depend on the final destination in Ticino and traffic flow at the crossings — factors that condition the daily commuter’s planning.

Anyone living in Mesenzana and working in Ticino falls fully under the frontier worker regime. The implications are both administrative and fiscal: obligation to register with INPS, respecting the days of presence in Italy to maintain frontier worker status, and adherence to Italian declaration regimes. Moreover, it will be necessary to evaluate the health‑insurance option (Swiss LAMal or Italian SSN) and understand the pension implications (AVS, LPP, unemployment insurance).

The New Frontier Workers Agreement and fiscal implications

The New Frontier Workers Agreement — signed on 23 December 2020 and ratified in Italy by Law 83 of 13 June 2023, entering into force on 1 January 2024 — introduced significant changes to the tax regime. The Article 9 transitional regime applies only to workers who meet the Agreement’s definition and worked in Graubünden, Ticino or Valais between 31 December 2018 and 17 July 2023; covered employment income is taxable exclusively in Switzerland. The ordinary regime applies in other cases, with Italian taxation and credit for Swiss tax where applicable. The €10,000 in Article 4 of Law 83/2023 is only the income limit referred to in Article 1(175) of Law 147/2013, not a general allowance. FTA factsheet · Agreement, Article 9 · Normattiva, Article 4. Old cross-border workers remain taxed only in Switzerland (Art. 9 of the 2020 Agreement).

This agreement represents an important evolution compared with the previous regime, as it simplifies certain declaration obligations and improves tax predictability for new commuters. However, anyone moving from Mesenzana to work in Ticino must understand the mechanism of the Italy‑Switzerland Convention against Double Taxation (signed 9 March 1976) and how the tax credit applicable in the CE section of the Italian 730 tax return recovers the taxes paid in Switzerland.

Operational details

Taxation and declaratory obligations

The tax system for those who reside in Mesenzana and work in Ticino follows precise rules. In Italy, the border worker is required to register with INPS as an employee and to file an annual tax return (Form 730 or Income Tax). However, the declared income is taxed in Switzerland, where the employer applies the tax at source. To avoid double taxation, Italy recognises a tax credit — indicated in the EC framework of declaration 730 — which allows taxes paid in Switzerland to be recovered.

The structure of the Swiss paycheck for a frontier worker includes deductions for:

• AVS/AI/IPG (old-age and disability insurance): 5.3% to be paid by the employee
• Unemployment (AD) and accident (AC) insurance: 1.1% up to CHF 148'200 of income
• LAINF (accident insurance): 0.7–1.5%
• LPP (pension fund according to pillar): 7–18% depending on the age group (from 25 years)
• Cantonal/municipal source tax: withheld as a percentage of gross income

In Italy, on the other hand, the border worker pays:

• INPS (social security contributions): percentage calculated by the Swiss employer on a bilateral basis
• IRPEF (Personal Income Tax): progressive rates from 23% up to €28,000, 33% between €28,001 and €50,000, 43% over €50,000

Key points

Pre-transfer Checklist

Before moving to Mesenzana and starting a frontier worker activity in Ticino, it is advisable to check some key points:

1. Employment Contract: Ensure that the Swiss employer is willing to offer a frontier worker contract with the appropriate deductions and communications to INPS.

2. Frontier Worker Permit (Permit G): Request the permit from the competent local Italian authority (municipality of Mesenzana) in coordination with the Swiss SEM (State Secretariat for Migration). The procedure varies depending on the destination canton for work.

3. Registration with INPS: Once hired, register with INPS as a frontier worker employee. The Swiss employer will submit contribution data in a bilateral scheme.

4. LAMal or SSN Choice: Decide within the established deadlines whether to keep Italian health insurance (free SSN) or switch to Swiss LAMal (with monthly premium).

5. Tax and Accounting Tracking: Prepare a system to keep Swiss pay slips, Italian tax declarations, and expense invoices (especially if you intend to seek deductions for commuting costs — although their deductibility depends on the applicable Italian regime).

6. Residence and Notifications: Register your change of residence at the Mesenzana municipality and notify INPS within 30 days.
