  • Withholding tax withheld only in Switzerland
  • Excess €10,000 for new frontier workers

Key facts

  • What: New Italy-Switzerland Border Agreement
  • When: Signed December 23, 2020, effective January 1, 2024
  • Where: Swiss Confederation and Italian Republic
  • Who: G border workers working in Switzerland and residing in Italy

The border agreement signed on 23 December 2020 entered into force on 1 January 2024, replacing the previous regime after Italian ratification with Law 83 of 13 June 2023. This agreement establishes that the tax at source on employee income is withheld exclusively in Switzerland, while Italy avoids double taxation through the tax credit to be declared in the EC framework of form 730. Switzerland confirms its position of not belonging to the European Union or the European Economic Area (EEA), as provided for in the Double Taxation Convention signed on 9 December 1976.

For frontier workers, the agreement introduces important distinctions: those who were already frontier workers before 17 July 2023 benefit from a transitional regime valid until 2033 with an exemption of €7,500, while new frontier workers (those who started their activity after that date) have

Practical analysis of the cost of living in St. Gallen in the national context

Living and working as a cross-border commuter in Switzerland involves a direct comparison between the costs incurred beyond the Alps and the purchasing power in Italy, which is particularly relevant for those who live in the province of St. Gallen. Although the source does not provide specific data on rents or consumer prices in the canton of St. Gallen, it is possible to analyze the tax and contribution implications that directly affect disposable income.

The €10,000 exemption for new cross-border commuters is a key element: this amount is deducted from the Swiss gross income before withholding tax is applied, reducing the tax base. For example, an employee with a gross annual income of CHF 60,000 would only see tax levied on CHF 50,000 after the deductible, resulting in tax savings compared to a full rate. This mechanism is particularly advantageous in cantons with low municipal rates, as may be the case in some San Welsh areas.

However, compulsory contributions in Switzerland have an impact on the net: in addition to withholding tax, 5.3% for AHV/IV/EO, 1.1% for ALV/AC (up to the ceiling), the variable UVG premium and the BVG contribution must be considered. These deductions, although intended for forms of social security, reduce the net salary received monthly. In Italy, on the other hand, the tax credit recognized allows you to offset all or part of the Swiss tax paid, avoiding double taxation through the declaration in the EC framework of 730.

Key points

Per gestire correttamente la propria posizione fiscale e previdenziale come frontaliero in Svizzera, è necessario seguire alcuni passaggi concreti basati sulle disposizioni dell'accordo in vigore dal 1 gennaio 2024. Prima di tutto, verificare la propria categoria: se si è iniziato a lavorare in Svizzera dopo il 17 luglio 2023, si rientra nella categoria dei 'nuovi frontalieri' con diritto alla franchigia di €10'000; se invece si era già attivi prima di quella data, si applica il regime transitorio con esenzione di €7'500 valido fino al 2033. Questa distinzione va comunicata tempestivamente al datore di lavoro svizzero affinché possa applicare correttamente la trattenuta alla fonte.

In Svizzera, l'imposta alla fonte viene calcolata e trattenuta direttamente dal datore di lavoro, che la riversa all'Amministrazione Federale delle Contribuzioni (AFC/ESTV) tramite le autorità cantonali delle contribuzioni. Non è necessario presentare una dichiarazione annuale in Svizzera unless si hanno altri redditi oltre quello da lavoro dipendente. Tuttavia, è fondamentale conservare il certificato di stipendio annuale, che riporta l'imposta alla fonte effettivamente trattenuta.

In Italia, entro i termini ordinari di presentazione del modello 730 (solitamente tra aprile e giugno dell'anno successivo), bisogna dichiarare il reddito prodotto in Svizzera nel quadro CE, indicando l'imposta alla fonte già versata. L'Agenzia delle Entrate riconosce poi un credito d'imposta pari all'imposta svizzera pagata, evitando così la doppia imposizione. È consigliabile rivolgersi a un CAF o a un professionista abilitato per la compilazione, soprattutto se si hanno detrazioni familiari o altri redditi da dichiarare.

Frequently Asked Questions
What is the allowance for new frontier workers after the 2020 agreement?
New frontier workers, i.e. those who started working in Switzerland after 17 July 2023, are entitled to an exemption of €10,000 on the income produced in Switzerland before the calculation of the tax at source. This exemption is provided for by the New Frontier Agreement signed on 23 December 2020 and in force from 1 January 2024, after Italian ratification with Law 83 of 13 June 2023.
How does the tax credit work in Italy to avoid double taxation?
In Italy, double taxation is avoided thanks to the tax credit to be declared in the EC framework of model 730. The withholding tax withheld in Switzerland on employee income can be reported in the Italian declaration, where the Revenue Agency recognizes a corresponding credit. This mechanism is provided for by the double taxation convention between Italy and Switzerland signed on 9 December 1976 and applies regardless of border status.
What are the rates of Swiss social contributions borne by the employee?
Swiss social contributions borne by the employee include: AVS/AI/IPG at 5.3% homeless, unemployment insurance (AD/AC) at 1.1% with an annual ceiling of CHF 148'200, accident insurance (LAINF) varying between 0.7% and 1.5% depending on the sector of activity, and occupational pension (LPP/BVG) ranging between 7% and 18% based on age, applicable from 25 years. These percentages are established by federal law and administered by the competent authorities.
