What is the difference between the €10,000 deductible for new frontier workers and the €7,500 exemption for old ones in 2026?

From 1 January 2024, the New Frontier Agreement differentiates the regimes: border workers who became such after 17 July 2023 (new) have a flat-rate exemption of €10,000, while old people (already border workers before that date) benefit from an exemption of €7,500 until 2033. The deductible represents the minimum non-taxable income in Italy; above that, ordinary personal income tax rates apply (23% up to €28,000, 35% up to €50,000, 43% over €50,000). In 2026, these limits remain active under the transitional regime.

How is the 730 CE tax credit calculated if I have children?

In the EC framework of the Italian Form 730, enter the total amount of withholding tax withheld from Switzerland (in CHF, converted to EUR). The Revenue Agency recognizes this credit up to the deductible due (€10,000 or €7,500 depending on your status). Above the deductible, apply the IRPEF rates. For children, state in the “Dependents” or “Universal Unique Allowances” section their tax code and date of birth; the Agency automatically applies deductions if the total income of the family falls within the limits.

Does Italy apply double taxation on labour income in Switzerland?

No. The bilateral Italy-Switzerland Convention of 9 December 1976 avoids double taxation. Switzerland withholds the tax at source (5.3% AVS/AI/IPG for employees, plus LAINF and cantonal contributions); Italy recognises the tax credit in the EC framework of the declaration, applying its personal income tax rates only on income that exceeds the deductible. The New Frontier Agreement (effective 1 January 2024) standardised this mechanism with differentiated deductibles.

What documents are needed to complete the EC framework in 2026?

Collect: (1) tax certification at source from the employer or the canton of Ticino; (2) December pay slips; (3) tax codes and dates of birth of children declared dependent; (4) any INPS receipts for contributions paid in duplicate. Convert the amounts in CHF to EUR according to the year-end exchange rate. Consult your CAF or accountant for a full review of documents specific to your situation.

Does the G Permit allow me to take advantage of the deductible in 2026?

Yes. The G Permit (Border Work Authorization) is the foundation of border status. With Permit G active, you are eligible for the New Deal deductibles (€10,000 if you became a frontier worker after 17/7/2023, €7,500 if earlier). Verify that your G Permit is renewed and valid at the time of the 2026 declaration.

Key facts

What: Tax credit for recovery of source tax withheld only in Switzerland
When: 2026 tax return (year 2025); Agreement effective 1/1/2024
Where: Box CE, Italian 730 form at the Revenue Agency
Who: Cross-border workers with Permit G (dependent work in Ticino/Switzerland)
Amount: €10,000 exemption for new, €7,500 exemption for old (transitional 2024-2033)
Source tax: Withheld ONLY in Switzerland (5.3% AVS/AI/IPG employee)
Bilateral convention: December 9, 1976 Italy-Switzerland (avoids double taxation)

In 2026, cross-border workers with children working in Ticino will continue to benefit from the tax credit for source taxes withheld in Switzerland. The system works as follows: Switzerland withholds income tax on work income according to its rates (AVS/AI/IPG 5.3% for employees, plus any insurance contributions LAINF 0.7–1.5% and cantonal); Italy, applying the bilateral convention of December 9, 1976 and the New Cross-border Agreement effective January 1, 2024, recognizes the tax credit in the 730 form, box CE, thus avoiding double taxation. The Italian return accounts for differentiated exemptions: €10,000 for cross-border workers who became such after July 17, 2023 (new), €7,500 for old cross-border workers with transitional regime until 2033.

Operational details

In concrete terms, how does the calculation of the tax credit for a border family with children in 2026 work?

Scenario: border crossing with two children

A border worker with two children, employed in Ticino with annual gross income, suffers Swiss withholdings from Switzerland (5.3% for AVS/AI/IPG employee, plus any LAINF 0.7–1.5% and administrative/cantonal contributions). The Swiss net amount is reduced by about 6-8% due to these withholdings. At the time of the Italian declaration, the taxpayer enters the total amount of withholdings in the EC framework and, thanks to the deductible of €7,500 (if old border) or €10,000 (if new), recovers the tax credit on part of the taxable amount.

In this way, the taxpayer does not suffer double taxation: Switzerland withholds a percentage, Italy recognizes the credit and applies its personal income tax rates only on income that exceeds the deductible. For a family with two children, the additional deductions (universal one-off checks, historically dependant deductions) further reduce the Italian net tax. Coordination with INPS ensures that family allowances are recognised as long as the total income of the family remains within the established limits.

Difference Between Old Regime and New Agreement

Before 1 January 2024, frontier workers were treated with less transparency about deductibles. The New Agreement has standardized the mechanism: a clear line between

Key points

Step-by-step procedure: completing section CE in form 730

1. Collect documents: receive from the Swiss employer (or from the competent canton through the municipal tax administration) the certification of source taxes withheld during the year. Also keep December payslips or cantonal tax certificates, as well as any receipts for contributions paid to INPS for pension contributions paid in duplicate. 2. Enter data in section CE: in the Italian 730 form, section "Foreign employment income", enter the gross amount earned in Switzerland (in CHF) and the total amount of source tax withheld, converted to EUR at the exchange rate of the fiscal year-end date. 3. Declare children: in the section "Dependent family members" or "Universal family allowances", list the children with their data (tax ID, date of birth, any personal income). The Revenue Agency will automatically apply deductions if the family income falls within the regulatory limits. 4. Verify the threshold: make sure you have clearly noted whether you are an old cross-border worker (exemption €7,500) or new (threshold €10,000). This determines which portion of income is taxable in Italy and which remains covered by the Swiss tax credit. 5. File the 730: submit the return through a CAF (Tax Assistance Center), a tax advisor, or online on the Revenue Agency portal by the ordinary deadline.

Deadlines and timelines

The deadlines for filing the 730 return follow the standard Italian calendar (generally May-June for the paper form, July for the electronic version). It is advisable to complete the compilation by the ordinary deadline to avoid penalties and quickly receive the tax credit.
