Context
The new tax agreement between Italy and Switzerland, fully operational for so-called "new cross-border workers" (hired after July 17, 2023), is set to redraw the fiscal map for thousands of workers. The one question everyone from Varese to Como is asking is: how much will I actually take home? To answer this, we've developed a concrete simulation, comparing the old and new regimes based on an annual gross salary of CHF 65,000, a representative figure for many professions in Ticino. Until now, "old cross-border workers" (those with an employment relationship existing before the fateful date) benefited from a simple system: exclusive taxation in Switzerland with tax refunds (ristorni) paid to Italian border municipalities. For them, nothing changes. But for a new hire working in Mendrisio, Lugano, or Bellinzona in 2026, the scenario is radically different. They enter the concurrent taxation regime: Switzerland levies a withholding tax, but Italy demands its share through the IRPEF income tax return. This transition is not just a bureaucratic formality. It means having to manage two tax systems, setting aside money for Italian taxes, and dealing with greater administrative complexity. Let's see in detail, numbers in hand, what this revolution means for our typical worker with a salary of CHF 65,000.
Operational details
Old vs. New Regime: The Simulation Let's analyze the net impact on a gross salary of CHF 65,000 for a cross-border worker residing in a border municipality, single, with no children. The figures are estimates based on current regulations and projections for 2026. 📊 Case 1: "Old Frontaliere" (Exclusive Taxation in Switzerland) - Annual Gross Salary: CHF 65,000 - Swiss Social Security Contributions (AHV/IV/EO/ALV, approx. 6.5%): -CHF 4,225 - BVG/LPP Contributions (estimate 5%): -CHF 3,250 - Taxable income for withholding tax: CHF 57,525 - Cantonal Withholding Tax (Ticino estimate, bracket A0): -CHF 6,300 - Annual Net Take-Home Pay: approx. CHF 51,225 For this worker, the tax story ends here. No tax filing obligation in Italy for this income. 📊 Case 2: "New Frontaliere" (Concurrent Taxation from 2026) The process has two steps: Switzerland and then Italy. Phase 1: Taxation in Switzerland - Annual Gross Salary: CHF 65,000 - Social Security and BVG/LPP Contributions: -CHF 7,475 - Swiss Taxable Income: CHF 57,525 - Swiss Withholding Tax (reduced to 80%): the Swiss rate cannot exceed 80% of the ordinary one. Therefore, CHF 6,300 0.80 = -CHF 5,040 - Provisional Swiss Net: CHF 52,485 Phase 2: Taxation in Italy - Income to declare (converted, hypothetical exchange rate 1.05): CHF 52,485 / 1.05 = EUR 49,985 - Non-taxable allowance (franchigia): -EUR 10,000 - IRPEF Taxable Income: EUR 39,985 - Gross IRPEF (calculated on 2026 brackets): approx. EUR 10,795 - Tax credit (Swiss tax paid): CHF 5,040 / 1.05 = -EUR 4,800 - Net IRPEF to be paid in Italy: 10,795 - 4,800 = EUR 5,995 - Municipal/regional surcharges (estimate 2%): 39,985 0.02 = EUR 799 - Total Italian Taxes: EUR 6,794 The final net is calculated by subtracting Italian taxes from the Swiss net: EUR 49,985 - EUR 6,794...
Key points
What to Do? Strategies for the New Regime The simulation is clear: for the same gross salary, the new tax regime is fiscally more burdensome for the cross-border worker. The net loss, in our example, is almost CHF 6,000 per year. This requires a shift in mindset and financial management. It's no longer possible to consider the net salary received monthly from Switzerland as final. 💡 Practical advice for "new frontalieri": - Monthly Savings: The first rule is caution. You need to calculate the estimated IRPEF tax and set aside a portion of your salary each month to avoid being caught short when filing your tax return in Italy. A good accountant specializing in cross-border taxation becomes an essential figure. - Tax Planning: Carefully evaluate all deductions and credits allowed by the Italian tax system. Medical expenses, mortgage interest, supplementary pension contributions (like the Pillar 3a) can help reduce your taxable income. - Monitor the Exchange Rate: The CHF/EUR conversion is a crucial variable. Significant fluctuations can alter both the taxable income in euros and the value of the tax credit. Using up-to-date tools is essential. These calculations, however detailed, remain an estimate. Your personal situation, municipality of residence, family dependents, and specific deductions can significantly change the final result. To get an accurate and personalized forecast of your net salary under the new rules, we recommend using our net salary calculator, which is constantly updated with the latest tax regulations.
