Neuchâtel cross-border workers 2026: 1983 agreement, form 2041-AS and French tax filing
Do you live in Doubs (Morteau, Pontarlier, Villers-le-Lac, Maîche) and work in the Canton of Neuchâtel? Under the Franco-Swiss agreement of 11 April 1983, your salary is taxed in France provided you file form 2041-AS.
2041-AS
Mandatory tax residence certificate preventing dual withholding tax
40%
Annual teleworking cap in France preserving cross-border tax status
45 nights
Maximum annual non-return tolerance to the French residence
€7,500
Maximum overtime tax exemption via schedule 2041-AE
Securing your Neuchâtel cross-border status and lowering your French tax bill
The 1983 agreement provides that a cross-border employee returning daily to France is exempt from withholding tax in Neuchâtel and taxed solely in France. Without submitting form 2041-AS stamped by the French tax office, the Swiss employer is legally required to deduct withholding tax.
Actual commuting mileage vs 10% flat deduction in France
For daily commutes between Haut-Doubs and La Chaux-de-Fonds, Le Locle or Neuchâtel, we systematically compare the automatic 10% flat allowance against the French mileage scale plus meal allowances.
Exact calculation of net taxable salary in euros
Full deduction of mandatory Swiss social contributions (AVS/AI/APG, AC, LPP, LAA-ANP, IJM) before applying the official 2041-AS exchange rate.
Tax reduction through LPP 2nd pillar buybacks
Unlike Pillar 3a, a 2nd pillar (LPP) buyback made through your Swiss pension fund reduces your certified net taxable salary in France as well as your Reference Tax Income (CMU).
Overtime exemption (2041-AE) and Swiss account reporting (3916)
Exemption of eligible overtime pay up to €7,500 net and compliant reporting of all Swiss bank accounts to avoid the €1,500 fine per undeclared account.

Frequently asked questions
Technical answers to your questions
Once your form 2041-AS is stamped by your French tax office, it can be submitted to the Neuchâtel tax administration or your employer to obtain a refund of the withheld tax.
Franco-Swiss agreements allow up to 40% of working time per calendar year to be performed remotely from France without altering the applicable tax regime.
As your taxable income grows, the flat-rate cross-border LAMal premium generally becomes significantly more cost-effective than the proportional CMU contribution (8% of RFR above the allowance).
