Analysis of social deductions The composition of the Swiss net salary is influenced by several mandatory contributions that reflect the Swiss social security system. For a worker, the paycheck typically includes AVS (Old Age and Survivors Insurance), AI (Invalidity Insurance) and IPG (Profit Loss Allowance), which together account for 5.3% of the employee's cost. To these is added the contribution for unemployment insurance (AD/AC) equal to 1.1%, calculated up to the maximum limit provided. Non-occupational accident insurance (LAINF) represents a further item, with an incidence that varies between 0.7% and 1.5%. Occupational pension (LPP/BVG) is a fundamental element for future pension savings, with rates ranging between 7% and 18% according to age group, starting from the age of 25. Compared to the previous situation, 2026 consolidates the application of the new regulations, making it necessary to monitor expenditure items in a timely manner to understand the actual purchasing power. While the source tax is fixed in the Swiss system, the overall tax burden also depends on the management of LAMal (health insurance) premiums. Border crossers in possession of the G permit have the right of option, being able to choose from the available deductibles, which usually vary between 300 and 2,500CHF for adults. This
