Key facts

• Signing of the New Cross-border Workers Agreement → 23 December 2020
• Italian ratification → Law 83 of 13 June 2023
• Withholding tax on earned income → only in Switzerland
• Convention against double taxation → 9 March 1976
• AD/AC → 1.1%, with cap CHF 148'200

• Italian IRPEF 2026 → 23%, 33%, 43%
• KVG → health insurance

On 1 January 2024, the New Cross-border Workers Agreement came into force, signed on 23 December 2020 and ratified in Italy with Law 83 of 13 June 2023. For the cross-border worker who checks his Swiss pay slip in the Canton of Ticino in 2026, this sequence is the starting point: the reference is not an agreement that came into force in 2026, but a regulation that is already operational.

The tax principle is clearly defined: the cross-border worker's income is withheld only in Switzerland. Italy avoids double taxation through the tax credit to be indicated in the EC framework of 730. It is therefore not a double withholding tax on the same income. The Italy-Switzerland Convention on double taxation was signed on 9 March 1976; Switzerland is not a member of the EU or EEA.

To read the payslip as a single person, it is best to separate the tax part from the social items. Withholding tax rates, including federal and cantonal ones, are established by federal and cantonal laws. At the federal level, administration is the responsibility of AFC/ESTV; at the cantonal level, the cantonal tax administrations intervene. UFAS and BFS do not set these rates: the first concerns social security, AVS/AI, while the second collects statistical data.

The dates that separate the regimes

The operational distinction concerns the date of 17 July 2023. Old cross-border workers, already cross-border workers before that day, have the exemption of €7,500 in the transitional regime 2024–2033. New cross-border commuters are included in the €10,000 exemption. The distinction precedes any reading of the net: before attributing a result to the condition of being single, one must place oneself in the correct category.

The Italian picture changes from 2026. For the Italian IRPEF three bands are indicated: 23% up to €28,000, 33% from €28,001 to €50,000, 43% over €50,000. For incomes 2024–2025 the reference remains 23%, 35%, 43%. The modification is referred to in Law 199/2025, article 1, paragraph 3.

Finally, the G permit, the AVS and the LPP enter into the pay slip control; for health coverage the correct term is KVG, i.e. health insurance, not "health tax". The new 2026 tax agreement must therefore be placed in the actual chronology: the New Cross-border Agreement operates from 1 January 2024.

Operational details

From gross to items that reduce net

The Swiss paycheck for 2026 cannot be interpreted with a single percentage. For a single cross-border commuter, the useful check is to combine the tax withholding with the contribution items and health coverage, without adding amounts that belong to different plans. The table collects the values ​​indicated for the employee or for the relevant contribution item.

Two comparisons to make before looking at the net

The first scenario concerns a cross-border worker who was already a cross-border worker before 17 July 2023: in comparison with the new regime, the data to highlight is the exemption of €7,500, valid in the transitional period 2024–2033. The second concerns a new cross-border worker: the threshold to be compared is the deductible of €10,000. They are two different readings of the same pay slip and should not be merged into an average.

The IRPEF calendar must also be kept separate. From 2026 the bands indicated are 23% up to €28,000, 33% from €28,001 to €50,000 and 43% above; for 2024–2025 they are 23%, 35%, 43%. These percentages describe the Italian situation and do not transform the Swiss withholding into a second income tax: the mechanism indicated remains the tax credit of the EC framework of 730.

For singles, the practical point is not to confuse the KVG item with the other deductions. A cross-border worker with a G permit has the right of option; the source also indicates deductibles for adults from CHF 300 to CHF 2,500. The deductible should not be transcribed as a salary rate: it is the health parameter reported for health insurance.

The real net therefore emerges from the separate reading of tax, AVS/AI/IPG, AD/AC, LAINF, LPP and KVG, not from the use of an indistinct total. To transform this grid into a personalized salary estimate you can use calcolatore fiscale, keeping the Italian tax part separate from the Swiss one.

Key points

Operational checklist for 2026

Paycheck verification does not require starting from a theoretical figure. It requires classifying each item and linking it to the correct regime. For single cross-border commuters, the following sequence helps to avoid confusing entry date, withholdings and health coverage.

Five checks on the payslip

1. Identify the regime. Note if you were already a cross-border worker before 17 July 2023. The answer addresses the comparison between the €7,500 exemption in the 2024–2033 transitional regime and the €10,000 exemption for new cross-border workers.

2. Isolate the tax. Search for the withholding tax on earned income and check the principle applied: for cross-border workers it is only in Switzerland. For the Italian side, the tax credit passes through the EC framework of 730, so the control remains consistent with the rule against double taxation.

3. Read the contributions one at a time. AVS/AI/IPG is 5.3% dependent; AD/AC is 1.1% with cap CHF 148'200; UVG is 0.7–1.5%; LPP is 7–18% per age group from 25th year. Do not replace one entry with another.

4. Separate healthcare. KVG means health insurance. If you are a G cross-border commuter, consider the right of option and the adult deductible between CHF 300 and CHF 2,500. The healthcare item must be read separately from social security.

5. Attribute responsibility. For federal and cantonal rates, the administrative reference is AFC/ESTV at federal level and the cantonal tax administration at cantonal level. UFAS does not set tax rates and BFS collects statistical data.

This grid also avoids confusing the envelope entries with other references to cross-border work, such as refunds, INPS or the Brogeda crossing. None of these terms replace the AVS, AD/AC, LAINF and LPP rates, nor change the principle of withholding tax. The same caution applies to the new 2026 tax agreement: the date to be verified remains 1 January 2024, not 2026.

To estimate the real net, enter in the reading only the values actually available on the pay slip and apply the 2026 calendar to the Italian IRPEF: 23% up to €28,000, 33% from €28,001 to €50,000, 43% over €50,000. For a working estimate of net, use simulatore busta paga.
