Ticino’s Tax Transfer Freeze Escalates Tensions with Rome

The tax dispute between Ticino and Italy has reached a new stage. The Ticino State Council has announced a freeze on 50 million francs in tax rebates due to Lombardy, against a backdrop of disagreement over the taxation of Italian cross-border workers. Bern disapproves, Italy is protesting, and companies employing cross-border workers are now viewing this issue with very real concern.

For Swiss SMEs, the issue goes beyond mere political debate. It concerns withholding tax, the attractiveness of Swiss wages, the availability of skilled staff and the stability of a bilateral framework on which many employers rely on a day-to-day basis. In border cantons, a change in the rules or prolonged uncertainty can quickly lead to issues with payroll, recruitment and budgeting.

Ticino is withholding part of the money promised to Italian municipalities

According to Le Temps, the Ticino government has decided to partially suspend the payment of nearly half of the tax refunds due to Italy, so that they can subsequently be redistributed to border municipalities. The amount withheld amounts to some 50 million francs. The President of the Ticino government, Claudio Zali, a member of the Lega dei Ticinesi, presented this decision as a precautionary measure pending further clarification.

The research report also mentions a precautionary suspension of 46 per cent of the tax refunds earmarked for Lombardy for the year 2026, due to legal and financial uncertainty. In other words, Ticino is not merely challenging a technical payment: it is using tax rebates as leverage to respond to what it considers to be a problematic development on the Italian side.

Tax rebates are a mechanism for compensation between states or local authorities. In this case, a portion of the tax paid in Switzerland by workers resident in Italy is returned to the relevant Italian municipalities. The idea is simple: these workers use infrastructure and services in their place of residence, whilst their income is taxed in the country where they work. The system therefore aims to prevent a border from shifting tax revenue too drastically from one territory to another.

But when the context changes, the mechanism becomes politically sensitive. For Ticino, the new Italian tax targeting certain cross-border workers upsets the balance. For Bern, the freeze on the amounts due poses a problem in terms of bilateral commitments. According to Le Temps and the research report, the Federal Council considers that Ticino’s suspension of tax rebates contravenes the agreement applicable to cross-border workers.

An old agreement, a new regime and two categories of cross-border workers

To understand the current tension, we need to look back at the tax framework linking Switzerland and Italy. The old 1974 agreement stipulated that Italian cross-border workers would be taxed exclusively in Switzerland. In return, 40 per cent of tax revenue was returned to their Italian municipalities of residence, according to the analysis published by PwC Switzerland.

A new agreement was signed on 23 December 2020 and came into force on 17 July 2023. It has changed the arrangements for new cross-border workers. Since 1 January 2024, they have been subject to concurrent taxation: Switzerland levies a withholding tax equivalent to 80 per cent of the standard tax rate, whilst Italy taxes the remaining income, taking into account a credit for the tax already paid in Switzerland.

This distinction is crucial for employers. A cross-border worker is no longer simply an employee resident on the other side of the border: the date on which they entered the scheme may determine the applicable tax treatment. Those already in post before 31 December 2023 benefit from a transitional arrangement until 2033. For these former cross-border workers, exclusive taxation in Switzerland is maintained, with a partial transfer of revenue to the Italian municipalities.

Within a company, this overlap of tax regimes complicates administrative management. Payroll must distinguish between different situations, correctly document the employee’s status and apply the relevant deductions. HR must also address very practical questions: what will the net salary be? Which country will tax what? What supporting documents need to be provided? These answers cannot be improvised, especially when tax rules interact with international agreements.

The Italian ‘health tax’ has set the powder keg alight

The recent trigger for the standoff is the introduction, in May 2026, of an Italian ‘health tax’ targeting cross-border workers benefiting from the old tax regime, according to Blick and the research report. This tax is expected to range from 3 per cent to 6 per cent of net pay. The stated aim on the Italian side is to fund higher wages for Italian healthcare staff and to stem the exodus to Switzerland.

The issue is a contentious one as it touches on the difference in attractiveness between the two labour markets. When a cross-border worker faces an additional financial burden in their country of residence, they may seek to offset this in salary negotiations. For the Swiss employer, this does not automatically create an obligation to cover these costs. However, in a tight labour market – particularly for certain specialist roles – the pressure may shift towards gross salaries, bonuses or other elements of remuneration.

This is where the institutional conflict becomes a business management issue. An SME in Ticino employing several Italian cross-border workers must anticipate individual discussions, avoid making hasty promises and clarify what falls under Swiss tax law, Italian tax law and the employment contract. The line between providing useful information to an employee and offering personalised tax advice is easily crossed. It is therefore prudent to provide general explanations and then refer individual cases to a competent adviser.

There is also a social risk. If two employees perform comparable roles but are subject to different tax regimes depending on their start date or place of residence, differences in take-home pay can fuel tensions. The remuneration policy must therefore be clearly explained: the company controls the contractual salary and the deductions it is required to make, but it does not control all aspects of the employee’s personal tax situation in their country of residence.

Bern, Bellinzona and Rome face a bilateral headache

The Confederation’s response is significant. According to *Le Temps*, the Federal Council regrets the Ticino decision and wishes to find a solution. The research paper states that it considers the suspension of tax rebates to be contrary to the agreement on cross-border workers. This position highlights a Swiss institutional reality: even when a canton is directly exposed to the economic effects of an agreement, the bilateral tax relationship also involves the Confederation.

On the Ticino side, the argument centres on the additional burden that the Italian tax would place on cross-border workers and, indirectly, on Swiss employers. The cantonal authorities cite legal and financial uncertainty to justify the partial suspension. On the Italian side, the government led by Giorgia Meloni defends the health tax as a tool designed to support the healthcare sector and retain professionals in Italy, whilst maintaining that Swiss rebates must continue to be paid.

For businesses, the challenge is not to settle the dispute between governments, but to manage the uncertainty. Until the authorities clarify the relationship between the existing agreements, the Italian tax and the withholding tax refunds, employers must avoid changing their tax practices without a clear official basis. When it comes to withholding tax, an error in withholding or classification can lead to subsequent adjustments, requests for clarification and administrative costs.

The SMEs concerned would be well advised to review their internal records of Italian cross-border workers: whether they are long-standing or new cross-border workers, their start date, canton of employment, place of residence, withholding tax regime, and any communications received from the authorities. The aim is not to compile a bulky file simply for the sake of compliance, but to be able to respond quickly should an employee, a government department or an adviser request information.

In businesses, it is better to err on the side of caution than to make last-minute adjustments

The first useful step is to keep the issues separate. The freeze on retrocessions concerns financial relations between authorities. The Italian health tax concerns the tax liability borne by certain cross-border workers in their country of residence. Swiss withholding tax relates to the obligations of the Swiss employer. These three areas are politically interlinked, but they are not managed in the same way on a payslip.

A company should therefore document what it currently applies and on what basis. HR and accounting teams can prepare an internal memo explaining the different schemes without commenting on the individual tax situation of each employee. In the event of requests for salary compensation, the discussion should remain focused on the company’s remuneration policy, the labour market and the role performed, rather than on automatically covering a foreign tax.

It is also advisable to monitor official communications and professional analyses. The media have reported on the political developments in the dispute, but practical adjustments must be validated using administrative sources or specialist advice. A payroll service provider can help verify withholding tax, identify employees who may be affected and prepare a cautious communication for staff.

Finally, this dispute serves as a reminder that the taxation of cross-border workers is not a minor issue. In Swiss regions that rely on a cross-border workforce, it affects employers’ competitiveness, the stability of teams and the transparency of net pay. The 50 million franc freeze in Ticino is a strong political signal; for SMEs, it is above all a call to secure their payroll processes and to closely monitor a situation that has not yet reached its conclusion.
