What is the tax difference between an old and a new frontier in 2026?

Old frontier workers (active before 17 July 2023) benefit from an annual exemption of €7,500 gross income until 2033, a transitional regime provided for by the new Agreement. The new frontier workers (from 17 July 2023) have a deductible of €10,000. This difference affects the taxable income declared in Italy: with the lower exemption, the gross taxable income is higher, increasing the Italian personal income tax and the tax credit to be calculated compared to the new frontier workers.

In which country do I pay tax at source on my border salary?

Tax at source is only withheld by the Swiss employer on your paycheck. The Swiss withholding tax certificate shows this withholding tax. In Italy, the frontier worker declares the Swiss gross income and obtains a tax credit to offset the withholdings already paid in Switzerland, avoiding double taxation according to the Italian-Swiss Convention of 9 December 1976.

What does' tax credit 'mean in the 730 Frontier model?

The tax credit is the Italian recognition of taxes already paid in Switzerland. In the EC framework of 730, the border agent declares the amount of Swiss withholding taxes (AVS, AD, LAINF and others). The Revenue Agency calculates the personal income tax due on the declared income and subtracts the credit, generating a refund if the Swiss taxes are higher than the theoretical Italian tax due on the same tax base.

What is the AVS/AI contribution rate that the border employee pays in Switzerland?

The employee rate for AVS (old age insurance), AI (disability) and IPG (maternity allowance) is 5.3% of the gross salary. This is a federal withholding tax applied by all Swiss employers. The employer pays a supplementary fee of 5.3%, but this does not appear on the paycheck of the border employee nor is it paid by him.

What should my Revenue Agency statement include if I work in Ticino and reside in Italy?

The Italian declaration (730 or PF Income) must include: gross income from employment obtained in Switzerland, withholdings paid in Switzerland (shown in the withholding certificate), any exemption or deductible according to the regime (old/new border), and the request for a tax credit in the EC framework. The deadline is 31 May of the same year for 730, or 30 September for telematic Income, depending on the method of sending chosen.

Double taxation avoided by the 1976 Italian-Swiss Convention

Key facts

What: New border tax regime Ticino-Italy
When: Entered into force on 1 January 2024
Where: Border workers working in Switzerland and residing in Italy
Who: G-licensed border workers employed by Swiss employers

On 1 January 2024, the new Border Agreement between Switzerland and Italy entered into force, signed on 23 December 2020 and ratified by Italy with Law 83 of 13 June 2023. This represents the first structural change in the taxation rules for border workers from Ticino and the Italian border provinces since the Italian-Swiss Convention of 9 December 1976. For 2026, the consolidated operating rules create a clear differentiation between border crossers based on the start date of cross-border activity. Understanding this system is essential for planning the tax return in Italy and providing the tax credit.

Operational details

Swiss rates and contribution charges

In 2026, Swiss tax rates remain stable according to federal and cantonal parameters. The withholding for AVS (old age insurance), AI (disability) and IPG (maternity allowance) is 5.3% of the employee's gross salary. The contribution for unemployment insurance (AD) and supplementary insurance (AC) amounts to 1.1%, with a maximum limit on which it is applied equal to CHF 148,200. The accident insurance (LAINF) varies between 0.7% and 1.5% depending on the sector and the company risk profile, while the contribution to the second pillar (LPP) varies between 7% and 18% based on the age group of the worker (from the 25th year onwards). These rates are administered at the federal level by the Federal Tax Administration (AFC/ESTV) and applied uniformly in all cantons.

Italian taxation and refills

In Italy, the IRPEF (personal income tax) is structured for progressive rates: 23% on income up to €28,000, 35% on income between €28,001 and €50,000, and 43% over €50,000. However, the border worker who declares the income obtained in Switzerland has the right to tax compensation: the Italian tax authorities recognise a tax credit corresponding to the withholding taxes paid in Switzerland. The mechanism of the refund (recovery of excessive taxes) depends on the effective rate paid in Switzerland with respect to the Italian rate that would be applicable on the same

Key points

Procedura dichiarativa e adempimenti 2026 Per il frontaliere che lavora in Svizzera e risiede in Italia, la dichiarazione dei redditi italiana rimane il fulcro dell'adempimento fiscale. Il modello 730 o il modello Redditi PF (Persone Fisiche) deve includere il reddito lordo da lavoro dipendente conseguito in Svizzera, anche se la ritenuta è stata già applicata alla fonte. Nel quadro CE del 730 ("Redditi da lavoro dipendente estero"), il frontaliere dichiara l'importo lordo e il credito d'imposta corrispondente alle ritenute svizzere. L'Agenzia delle Entrate verifica la coerenza tra la ritenuta dichiarata e le aliquote svizzere effettive, calcolando eventuali ristorni o addizionali. La documentazione richiesta include il certificato di ritenuta svizzero, che riporta il reddito lordo, le ritenute per AVS/AI/IPG, AD/AC e LAINF. Tale certificato deve pervenire al frontaliere in copia e deve essere trasmesso all'Agenzia delle Entrate in allegato alla dichiarazione. ### Scadenze e strumenti disponibili Per il 2026, la scadenza del modello 730 rimane il 31 maggio per la presentazione tramite CAF o tramite software di dichiarazione. I datori di lavoro svizzeri trasmettono i dati alla fonte svizzera (AFC) secondo i calendari federali; la sincronizzazione tra il sistema svizzero e l'Agenzia Entrate italiana avviene attraverso accordi amministrativi bilaterali. Per stimare concretamente l'impatto fiscale del vostro reddito lordo, del cantone di lavoro e del domicilio italiano, il calcolatore di busta paga consente di visualizzare la ritenuta svizzera effettiva, i contributi AVS/LPP e l'importo netto mensile. Inserendo il reddito lordo annuo e il cantone ticinese, lo strumento simula anche l'impatto della dichiarazione italiana e la stima del credito d'imposta. Potete così pianificare il bilancio personale e prevedere eventuali ristorni. È altamente consigliato aggiornare la simulazione ogni anno in base ai cambiamenti di aliquote, franchigie e regimi cantonali.
