Cittiglio, a municipality in the province of Varese located near the Ticino border, represents an interesting housing choice for cross-border workers who work in Canton Ticino. From January 1, 2024, the entry into force of the New Cross-border Agreement signed on December 23, 2020, has introduced significant benefits for those who choose to work in Switzerland and reside in Italy. The withholding tax on employment income is deducted in Switzerland, avoiding double taxation. 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.

The cross-border tax regime after the New Agreement

The taxation for those residing in Cittiglio and working in Ticino follows the model of the Italy-Switzerland Convention to avoid double taxation, signed on March 9, 1976. Italy recognizes the right of the cross-border worker to opt for the flat-rate regime, thus avoiding the submission of a complete tax return in Italy. In Switzerland, the taxpayer is subject to federal and cantonal rates, as well as contributions to AVS/AI/IPG (5.3% borne by the employee) and accident insurance LAINF (0.7–1.5% depending on the sector). The regime is particularly advantageous for those with a moderate income and a family in Italy.

Those residing in Cittiglio also have the option to choose Swiss health insurance (LAMal), instead of maintaining Italian coverage. This choice can represent a saving if the management of double coverage is costly. LAMal costs vary based on age, gender, and canton of insurance, with adult deductibles ranging from CHF 300 to CHF 2,500. Regarding pensions, the cross-border worker, by paying AVS/AI in Switzerland, accumulates pension rights that, combined with Italian INPS contributions, form a combined amount at the time of retirement.

What to consider before moving to Cittiglio

Before choosing Cittiglio as a place of residence, it is essential to verify the status of cross-border worker (permit G) with the Ticino cantonal authorities and the documentation related to the declaration to the Italian tax authorities. Permit G is dedicated to EU/EFTA citizens who work in Switzerland and reside outside national borders. Registration with the Registry of Persons (Italian registry office) and communication to the Swiss tax authorities of the transfer are mandatory steps. It is not permitted to pretend a fixed residence if the stay is occasional; the cantonal authority can verify the actual domicile through telecommunications, the energy bill, and registration with local public services.

Operational details

Economic advantages of residing in Italy

Living in Cittiglio offers concrete economic advantages compared to staying in Ticino. Firstly, the cost of living for rent and services in the province of Varese is significantly lower than in urban centers in Ticino such as Lugano or Bellinzona. Although specific amounts are not available, it is known that the province of Varese offers competitive real estate opportunities compared to the Ticino market. A commuter who resides in Cittiglio maintains full access to Swiss tax benefits (taxation in Switzerland, exemption/allowance) while benefiting from Italian housing costs, creating a positive economic differential. Additionally, the general cost of living in Cittiglio (food, services, energy rates) is lower than in the Canton of Ticino, offering further monthly savings.

The move: before and after the New Agreement

Before the entry into force of the New Agreement (1 January 2024), the tax regime was less favorable. 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. This change makes the choice to move to Cittiglio more attractive for those starting their commuter journey. Those who were already commuters before July 2023 can choose to adhere to the transitional regime, maintaining acquired benefits, or opt for the new regime if more convenient. Law 83 of 13 June 2023 ratified the New Agreement in Italy, providing full regulatory certainty.

Disadvantages and risks of commuting

Living in Cittiglio also involves critical aspects. Daily commuting from Cittiglio to the main work centers in Ticino (Lugano, Mendrisio, Bellinzona, Locarno) requires crossing borders (Brogeda, Chiasso, Gaggiolo). Transborder commuting can expose to delays due to customs controls, traffic, strikes of public transport in Switzerland or Italy, and critical weather conditions in winter. The commuter must plan safety margins in travel times and consider the cost of mobility: regional transport subscriptions, Swiss vignettes for the car, fuel, maintenance. Furthermore, they must manage tax compliance in two systems (Italy and Switzerland), with different deadlines and double documentation; while benefiting from taxation in Switzerland, communication to the Italian tax office and the flat-rate declaration require attention and precision.

Key points

Practical procedure: checklist before moving

First step: obtain the G permit from the cantonal authority of residence in Ticino. Second: register with the Cittiglio Registry Office, indicating Switzerland as the place of work. Third: inform the Swiss employer of the move, who must notify the cantonal administration of contributions (AFC/ESTV) for the adjustment of withholding tax. Fourth: register with the Italian Revenue Agency in the new place of residence and indicate the frontier worker income. Fifth: check with the employer if the additional voluntary payment for the Swiss third pillar (3a) is available, which offers federal tax deductions. Sixth: choose whether to keep the Italian health insurance (CMI) or opt for the Swiss LAMal, considering costs and coverage.

Tax deadlines to remember

Each year, the frontier worker residing in Cittiglio must comply with the Swiss tax deadlines related to the pay slip (the withholding tax is calculated monthly by the employer) and the Italian deadlines for the flat-rate declaration (usually by June of the following year, with terms set by the Revenue Agency). Old cross-border workers remain taxed only in Switzerland (Art. 9 of the 2020 Agreement). For those subject to additional payments (e.g., third pillar 3a), the deposit deadlines with the financial intermediary are usually set for December 31 of the relevant tax year. It is not allowed to postpone the communication to the Italian tax authorities; delay can result in administrative penalties.

Support tools and advice

To simulate the tax impact of choosing to move to Cittiglio, the frontier worker can use the salary calculator of Frontaliere Ticino, which calculates the Swiss withholding tax, AVS/LPP contributions, and estimates the net monthly income. It is advisable to consult an Italian accountant specializing in frontier worker regimes (for IRPEF aspects and declaration) and a Swiss advisor for planning additional contributions and the third pillar. Some cantons in Ticino offer dedicated offices for frontier workers at the municipal administrations. The Italian-Swiss Convention (9 March 1976) and the New Agreement (effective from 1 January 2024) are available at the Italian Revenue Agency and the Swiss Federal AFC. Downloading these documents and reading them with a local expert reduces the risk of procedural errors and tax omissions. Do not rely on informal recommendations from friends; each personal situation (marital status, dependents, possible secondary income) can have different implications.
