The 13th month salary calculator determines how the "tredicesima" (13th month payment) works for cross-border workers in Switzerland. In Swiss employment, the 13th month salary is a contractual provision rather than a legal obligation, but it is standard practice in most Ticino sectors and covered by collective labour agreements (CCL/GAV).
The calculator shows how the 13th month is distributed: typically paid in December as a full monthly gross salary, subject to the same social deductions (AVS, unemployment, LPP) and withholding tax as regular monthly pay. This means the net 13th month may be lower than expected if your marginal tax bracket is higher.
For Italian tax purposes, the 13th month is part of your total Swiss employment income and must be included in the annual IRPEF calculation. The guide clarifies the timing: Swiss CU documentation reflects 13 monthly payments, while Italian tax rules require annualised income reporting.
