Can I work from a third country without notifying the employer?

No. Failure to notify exposes you to legal sanctions and interruption of insurance payments. Written notification is mandatory to maintain compliance with Swiss labour law.

What if I don't have LAMal while working remotely abroad?

You risk refusal of reimbursement for medical treatment and administrative penalties in Switzerland (up to CHF 20,000). Continuity of insurance is critical for future performance.

How do I declare income if I work from a third country?

You must declare it in Italy (IRPEF) and in Switzerland as foreign income, using the tax credit (EC framework of 730) to avoid double taxation.

Working remotely from a third country: tax and insurance implications (cross-border guide)

Di Valerie Linc · Published on 17 July 2026

Practical guide for border workers Ticino-Italy: what you risk if you work from a third country during the holidays and how to comply with tax and insurance rules.

Context

In a nutshell

Swiss source tax applies only if you work from home in Italy (tax residence)
Communicate in advance to the employer the period and place of remote work
Mandatory LAMal also abroad: check coverage or option for exemption
New Frontier Agreement 2024: €10,000 excess for new frontier workers

Key facts

What: Remote work from a third country during CH-IT border worker holidays
When: Regulations in force from 1 January 2024 (New Frontier Agreement)
Where: Canton of Ticino and Italy (border residence)
Who: Border workers with G Permit and Swiss employer
Amount: New frontier deductible €10,000 (old €7,500 transitory)

The phenomenon of remote work from holiday resorts in third countries (e.g. Spain, Greece) during the holidays is growing among Italian-Swiss border workers. However, this practice triggered without prior communication to the employer and without assessing the tax and insurance implications exposes you to real risks. The current legislation derives mainly from the New Frontier Agreement in force since 1 January 2024 (ratified by Italy with Law 83/2023) and the 1976 Italy-Switzerland Double Taxation Convention.

Taxation: source tax and tax credit

Employee income tax at source is only withheld in Switzerland for border workers (cantonal/federal rates administered by AFC/ESTV). This is

Operational details

Practical Implications and Concrete Scenarios

What to Communicate to the Swiss Employer

Preventive Notification Obligation: Before activating remote work from a third country, the border worker must communicate to the employer: 1. Exact period of remote work 2. Specific location (country and address) 3. Confirmation of maintaining LAMal or taking out an equivalent insurance policy

This written communication is essential to avoid disputes on the respect of Swiss labor law and to ensure the continuity of insurance payments.

Comparative Fiscal Scenarios

Case 1: Border worker works 2 weeks in Ibiza (Spain)

Withholding tax: Not withheld in Switzerland (work outside Italy/Switzerland)
Taxation: Taxable income in Italy (IRPEF) and in Switzerland as abroad (tax credit)
Risk: Unreported declaration in Italy → Tax inspection with fines up to 40% of the tax gap.

Case 2: Border worker works from home in Lombardy (Italy)

Withholding tax: Withheld regularly in Switzerland (5-15% depending on income)
Taxation: Italy grants tax credit → No double taxation
Advantage: Simplified declaration (only CE form in the 730)

Insurance Risks

The absence of valid LAMal coverage during remote work from abroad can lead to:

Refusal of reimbursement for medical care received in the third country
Administrative fines in Switzerland (up to CHF 20,000 per offense)
Interruption of insurance continuity with impact on future benefits (maternity, disability)

New vs Old Regime for Border Workers
