Practical analysis for the cross‑border worker
Choosing to live in Brenna and work in Ticino entails several practical implications. The first aspect is the cost of living, which varies significantly between Italy and Switzerland. A cross‑border worker residing in Brenna can optimise their savings thanks to the cost difference between the two countries.
Calculation of net salary and social security contributions
To understand the real impact on net salary, it is essential to analyse Swiss social security contributions. The AVS/AI/IPG deductions amount to 5.3% borne by the employee. Unemployment insurance (AD/AC) is set at 1.1% with a maximum ceiling of CHF 148,200. Moreover, the LAINF (accident insurance) describes the LAINF rate between 0.7% and 1.5%.
Regarding occupational pension (LPP), contributions vary from 7% to 18% depending on the age band, starting from 25 years. This two‑pillar pension system is fundamental for the worker's long‑term financial planning. In Italy, IRPEF is applied with progressive rates: 23% up to €28,000, 33% between €28,001 and €50,000, and 43% above €50,000.
Health management and insurance
A critical aspect is health insurance. LAMal is the mandatory health insurance, not a tax. Cross‑border workers with a G permit have an option right to choose between Swiss insurance or that of their country of residence. Deductibles for adults are set between CHF 300 and CHF 2,500. Health management is the final piece to complete the relocation planning to Brenna for those working in Ticino.
