What documents do I need to apply for the G permit from Mesenzana?

For the G permit it is necessary to have an employment contract with a Swiss employer and submit an application to the competent authorities (SEM in Switzerland and municipality of Mesenzana). The required procedure and documents vary depending on the canton and local constituency. It is advisable to contact the municipality of residence and the employer to obtain the complete list of required documents.

Is the source tax withheld in Italy or Switzerland?

Tax at source is withheld exclusively in Switzerland by the employer. In Italy, the frontier worker will declare the income in form 730 and will recover the taxes paid in Switzerland by means of the tax credit (EC framework). This mechanism avoids double taxation, as provided for in the Convention between Italy and Switzerland signed on 9 December 1976.

Do I have to register with INPS if I work as a border worker in Ticino?

Yes. Border workers with a G permit must register with INPS as employees and pay contributions (collected by the Swiss employer through a bilateral procedure). Registration is mandatory to access Italian pension and insurance benefits. The employer will communicate the data to INPS in a coordinated manner.

What is the difference between permit G and permit B for those living in Mesenzana?

The G permit is intended for frontier workers and allows them to work in Switzerland while residing in Italy. The B permit is for seasonal or contingent workers. The two regimes have different implications on taxation, AVS/LPP, LAMal and residence rights. The choice depends on the employment contract offered by the Swiss employer and the expected duration.

Does the Swiss LAMal or the Italian SSN suit me?

It depends on your needs and family situation. The Swiss LAMal offers coverage in Switzerland and access to Ticino services; the Italian SSN is free but may have access limits in Switzerland. Evaluate LAMal premiums (CHF 300-2500 per year for adults) and compare them with your family situation (spouse, children) using our LAMal comparator.

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)

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 exclusively 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.

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 exclusively 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, 35% between €28,001 and €50,000, 43% over €50,000

Sickness insurance and social security

Health insurance (LAMal) is mandatory for those who
