What are the tax rates applied to border workers in Switzerland?

Tax at source is established by federal and cantonal laws, administered by the Federal Tax Administration (FTA). Rates vary based on the worker's income and family situation. It is the employer who withholds the amount directly from the monthly paycheck, then pays it to the competent cantonal authority, which regulates the accounts according to the directives in force.

How does the €10,000 deductible for new frontier workers work?

For border workers hired from 1 January 2024, the new agreement provides for a tax exemption of 10,000 euros. This amount does not contribute to the formation of taxable income for income tax purposes in Italy, representing a direct tax benefit. This threshold must be correctly reported in the Italian tax return to avoid excessive taxation on income received in Switzerland.

To avoid double taxation, the taxpayer must assert the tax credit, which allows to subtract the taxes already paid at source in Switzerland from the taxes due in Italy, in accordance with the Convention against Double Taxation of 9 December 1976.
