How is the border tax handled in 2026?

For frontier workers, income tax is withheld at source directly in Switzerland. The employer applies the rates established by the cantonal administration of reference. This system, in combination with the tax credit provided for by the EC framework of 730 in Italy, avoids double taxation.

What are the applicable deductibles for frontier workers?

The New Frontier Agreement, in force from 1 January 2024, establishes a deductible of 10,000 euros for new frontier workers. For the so-called 'old frontier workers', i.e. those who were already such before 17 July 2023, an exemption of 7,500 euros is provided, managed within a transitional regime that will last until 2033.

Who sets tax rates in Switzerland?

Tax rates are defined by federal and cantonal laws. The Federal Tax Administration (AFC/ESTV) manages the principles at the federal level, while cantonal tax administrations set specific rates and multipliers for their territory. The UFAS and the BFS have no competence in setting such rates.

Key Facts

What: Cantonal tax on earned income.
When: Fiscal year 2026.
Where: Switzerland, with an in-depth look at the Canton of Vaud.
Who: Federal Tax Administration (FTA/ESTV).
Amount: Variable depending on the canton and taxable income.

The Swiss tax landscape for the year 2026 remains complex, with a division of competences that sees the Federal Tax Administration (FTA/ESTV) define the general principles, while the individual cantons retain the right to set their own rates. This cantonal autonomy generates significant differences in the overall tax burden for taxpayers. In the Canton of Vaud, as in other cantons, the system is based on income brackets that determine the progression of the tax. It is essential to underline that for cross-border workers, withholding tax is the standard method of levy, withheld directly by the employer in Switzerland. This mechanism avoids double taxation, thanks to the tax credit provided for by the EC framework of 730 in Italy. The current legislation, including the management of the New Cross-Border Workers' Agreement which came into force on 1 January 2024, defines the applicable exemptions: 7,500 euros for 'old' cross-border workers, under a transitional regime until 2033, and 10,000 euros for new hires. The double taxation agreement between Italy and Switzerland, signed on 9 December 1976, remains the fundamental pillar of this cross-border balance. The calculation of the tax does not depend on institutions such as the FSIO, which is responsible for social security, but follows the directives of the cantonal administrations.

Operational details

The practical analysis of cantonal taxes requires a clear understanding of the deduction mechanism. In addition to income tax, the employee is subject to compulsory social contributions: AHV/IV/EO at 5.3% for the employee, AD/AC at 1.1% (with a ceiling calculated on an income of CHF 148,200), and variable quotas for UVG (0.7–1.5%) and BVG (7–18% depending on the age group, from the age of 25). These deductions reduce the tax base, but represent a fixed cost that must be considered in the national comparison. Compared to the Italian system, which is characterised by IRPEF brackets (23% up to €28,000, 35% up to €50,000 and 43% above this threshold), the Swiss system offers greater fragmentation.

Key points

The procedure for the proper management of tax obligations in 2026 requires constant attention. For the cross-border commuter, the Swiss employer acts as a withholding agent, withholding tax at source according to the tables provided by the cantonal tax administration. It is essential to check that the deduction is correct and that the salary statement accurately reflects what has been paid. If in doubt, you can request a separate statement or correction, following the procedures provided by the canton of employment.
