Practical Implications for Cross-Border Workers

Understanding payroll deductions is crucial for personal financial planning. For cross-border workers who commute daily through checkpoints like Ponte Tresa, Gaggiolo, or Brogeda, knowing how much is deducted from their gross salary is essential to calculate their monthly net income. Additionally, contributions paid in Switzerland can have implications for future pensions.

For instance, AVS constitutes the first pillar of the Swiss pension system and is coordinated with Italy's INPS under bilateral agreements between Switzerland and Italy. This means that contribution years in Switzerland and Italy are combined for pension calculation purposes, but it is important to pay attention to the specific regulations of each country.

📊 Real Example: A cross-border worker earning 72,000 CHF gross annually in 2026 will see approximately 3,816 CHF deducted for AVS/AI/IPG and 1,584 CHF for AD, in addition to contributions for LPP and LAINF. These amounts are deductible from the taxable base for Italian tax calculations, reducing the overall tax impact.

💡 Tip: It is advisable to request an annual breakdown of deductions from your employer to verify the accuracy of contributions and to simplify your tax return process in Italy.
