The agreement requires tax residence in a municipality on the jointly agreed 20 km list, work in Ticino, Graubünden or Valais, and in principle a daily return home. Up to 45 work-related days without a daily return are allowed per calendar year. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
A worker may qualify if the fiscal cross-border conditions were met and qualifying work was performed in Ticino, Graubünden or Valais on July 17, 2023, or during the period from December 31, 2018 to July 17, 2023. ESTV states that there is no minimum employment period; the other applicable conditions still have to be met. The agreement’s fiscal definition requires a daily return home in principle. Weekly return is a separate EU/EFTA G-permit requirement, not the agreement’s fiscal test. New fiscal cross-border workers pay 80% of the ordinary Swiss withholding-tax rate, while Italy grants a credit for Swiss tax paid under its rules.

No. Classification depends on meeting the fiscal conditions and having qualifying work in the period set by the agreement, not solely on the date of the current contract. Check your work history and circumstances with the competent tax authority. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
No. Changing employers does not by itself end the regime. A qualifying period can precede the current job; the fiscal requirements and the facts of the individual case still need to be checked. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
For new fiscal cross-border workers, Switzerland applies 80% of the ordinary withholding-tax rate. Italy taxes the income under its rules and grants a credit for Swiss tax paid, subject to the applicable conditions. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
No. It is the portion of the ordinary Swiss withholding-tax rate applied to new fiscal cross-border workers. It does not divide income or tax revenue between the two countries. Italy applies its own rules and the eligible credit for Swiss tax paid. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
Article 4 of Italian Law 83/2023 provides a €10,000 allowance for qualifying cross-border employment income under Italian tax rules and for the tax periods specified by law. It is not an automatic refund and does not reduce Swiss tax. Check eligibility and reporting in your Italian tax return.

Italy grants a credit for Swiss tax paid on the relevant income. The credit is calculated under the Italian rules that apply to the individual case; it is not an automatic refund of Swiss tax. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
No. 2033 is the final tax year for the 40% intergovernmental compensation paid by the Swiss cantons concerned to Italy. The ESTV document does not identify it as an automatic expiry date for an individual worker’s tax status.

The agreement uses the official bilateral list of municipalities in the 20 km zone, not a measurement from an individual address. Being on the list alone is not sufficient: the other fiscal conditions must also be met. ESTV: https://www.estv.admin.ch/dam/it/sd-web/Zbr5Jb-40aYm/int-laender-it-faktenblatt-faqs-it.pdf
No. For EU/EFTA citizens, the G permit concerns living abroad, working in Switzerland and returning at least weekly; it has no border-zone requirement. The Italy–Switzerland tax agreement has separate fiscal conditions, including residence in a listed 20 km municipality and, in principle, daily return.

For the agreement’s fiscal definition, up to 45 days per calendar year without a daily return are allowed for professional reasons. If the limit is exceeded, the ESTV says the person loses fiscal cross-border worker status under the agreement for that year.

The option depends on citizenship, residence and insurance circumstances. EU/EFTA/UK cross-border workers with a G permit are subject to Swiss insurance from the start of employment; eligible people insured in their country of residence must submit a formal exemption request to the competent canton within three months. A tacit choice is not valid. FOPH/BAG: https://www.bag.admin.ch/it/assicurazione-malattie-lavoratori-frontalieri-in-svizzera
Check the official tables for the tax year and canton of employment. In Ticino, the tariff depends on the applicable category and personal details; also verify the agreement’s fiscal conditions for cross-border status. The calculator provides an estimate and does not replace an authority’s decision. Canton Ticino: https://www4.ti.ch/index.php?id=64917
