Operational details

The practical analysis of maintenance requires a clear distinction between gross income and net income in Switzerland, taking into account the specific tax rules. While in Italy the IRPEF follows progressive tax brackets (23% up to 28,000 euros, 35% up to 50,000 euros, 43% above), the tax system for frontier workers in Switzerland is based on the payroll tax, which is harmonized according to the cantonal directives. The recognition of a foreign divorce decree in Switzerland requires specific procedures, which include formal recognition or homologation to ensure that the maintenance provisions are enforceable against the Swiss employer, if necessary, by pledging the salary. The situation is further complicated for what are known as 'old frontier workers', i.e., those who worked in Switzerland before July 17, 2023, who benefit from a transitional regime until 2033 with a tax-free threshold of 7,500 euros. For new frontier workers, the tax-free threshold is 10,000 euros. These fiscal differences affect the calculation of the net income actually received by the obligated spouse. It is crucial, in the context of negotiating the maintenance allowance, to present transparent documentation that includes not only the monthly salary but also mandatory deductions for professional insurance (LPP) and health insurance (LAMal). Many frontier workers choose LAMal and the right to opt-in, with tax-free thresholds that vary between 300 and 2,500 francs. The cost of these coverages, if borne directly by the obligated spouse, should be considered as a primary expense. To understand the impact of such costs on the family budget, one can consult our guide on the cost of living in Switzerland, which helps to contextualize the necessary expenses for maintaining a decent standard of living in the Swiss territory.

Key points

The procedure for determining the maintenance allowance in a transnational context requires accurate documentation, preferably with the assistance of legal experts familiar with both Italian family law and Swiss practices. The first step involves collecting all documentation related to Swiss income, including salary certificates and annual wage statements that show contributions to INPS (if applicable for totalization) and Swiss entities such as the compensation funds AVS. It is crucial that any separation or divorce agreement be drafted in a way that is recognized by the competent authorities of both countries. If there is a need to vary the allowance due to changes in working or tax conditions, it is necessary to activate the review procedures promptly. Failure to update income data can lead to significant imbalances, especially considering the fluctuations of the CHF/EUR exchange rate. To monitor such variations, it is useful to use our exchange rate comparator, which allows you to estimate the real value of the maintenance allowance in euros. Remember that the recognition of a foreign judgment in Switzerland is not automatic and follows the norms set by the Federal Act on Private International Law. For those facing new professional challenges or changes in Switzerland, it is always advisable to check the current opportunities through specialized portals. We invite readers to regularly consult the tools available on our portal for a conscious management of personal finances, starting with our salary calculator to always have under control the net monthly income based on the current deductions.

Frequently Asked Questions
What tax is levied on a frontier worker's salary?
The frontier worker is subject to tax at source in Switzerland. This deduction is the only one applied to income from work in Swiss territory. To avoid double taxation, Italy allows to deduct the taxes paid in Switzerland through the tax credit in the EC framework of the model 730.
How is the maintenance check calculated?
The allowance is calculated on the basis of net disposable income, i.e. gross salary less mandatory contributions (AVS/AI/IPG, AD/AC, LAINF, LPP) and tax at source. It is also necessary to consider the sickness fund costs (LAMal) incurred by the obligated spouse.
Does the New Frontier Agreement affect divorce?
The New Frontier Agreement, in force from 1 January 2024, regulates taxation and deductibles (10,000 euros for new frontier workers, transitional regime for old ones). It does not change the divorce laws, but the change in net taxation affects the contributory capacity of the spouse.
