Cross-border workers will be at the heart of significant transformations in 2025, with legislative and tax developments disrupting their daily lives. Notable advances include the amendment to the tax treaty between France and Luxembourg, which redefines the tax landscape for nearly 100,000 cross-border workers, a constantly growing number. This new framework aims to address persistent ambiguities in taxation, particularly related to teleworking, as well as to strengthen cooperation between tax administrations. At the same time, the 2025 Finance Act includes specific measures for non-residents, extending tax recovery deadlines and offering new opportunities for recourse to affected taxpayers.
This legislative momentum, widely supported by organizations such as Eurojuris, Deloitte, PwC, and the Leclerc Law Firm, calls for a thorough examination of available legal solutions to defend the rights of cross-border workers in the face of rapidly changing regulations. Between simplified administrative procedures, litigation, and tax negotiations, cross-border workers now have a range of legal tools to leverage to secure their situation. Furthermore, the rise of remote working requires increased vigilance regarding the rules to be followed to avoid adverse effects, such as double taxation or challenges to tax resident status.
Finally, this article highlights key services and industry players, such as the Vialegis Group, Fidal Avocats, and Champlain Avocats, who support cross-border workers in their legal processes, particularly in the context of complex disputes or tax claims. Discover the most appropriate avenues of recourse, how to proceed, and who to contact to benefit from optimal support, using concrete examples and practical advice tailored to your situation.
The Impact of the Franco-Luxembourg Tax Amendment on Possible Remedies for Cross-border Workers
The amendment to the tax treaty signed between France and Luxembourg in 2025 introduces major changes to the status and taxation of cross-border workers. This is an essential focus for understanding the new legal remedies available.
Redefinition of Cross-border Worker Status: Legal Consequences
Traditionally limited to residents living in a defined border area, cross-border worker status now extends to any French taxpayer working in Luxembourg. This development provides broader access to the specific protections and rules defined in the tax treaty.
From a legal perspective, this extension means that more workers can challenge tax decisions that violate the revised framework through administrative or legal channels. For example, in cases of abusive taxation due to an incorrect assessment of cross-border status or during tax reviews conducted by Société Générale or partner agencies, cross-border workers can seek the assistance of legal experts such as those at Champlain Avocats or Eurojuris.
- 📌 Increased ability to challenge tax adjustments
- 📌 Easier recourse to appeals before administrative or tax courts
- 📌 Simplified access to tax mediation to amicably resolve disputes
Adjustments to income taxation and associated appeals
With the new agreement, income taxation rules have been refined. The location of work and the number of days spent teleworking are now determining factors in the tax base.
This means that workers who are taxed outside the established rules, particularly regarding the annual threshold of 34 days of teleworking in France, have a solid basis for appeal. Specialized firms such as Fidal Avocats and LexCase offer their expertise to contest tax assessments and defend the rights of cross-border workers in these situations. 📅 Situation
| ⚖️ Applicable Taxation | 🛠️ Possible Appeals | Teleworking ≤ 34 days/year |
|---|---|---|
| Taxation in Luxembourg | Minimal control, rare appeal | Teleworking > 34 days/year |
| Taxation in France on excess days | Tax disputes with the French administration | Recovery due to misinterpretation |
| Possible double taxation | Tax mediation, administrative and judicial appeal | Appeals often favor prior negotiation, in particular thanks to the support offered by various organizations, including Deloitte and PwC, which assist in building solid cases. As a last resort, the competent courts will be contacted when negotiations fail. |

The adopted Finance Act introduces several new provisions for non-resident taxpayers, with significant implications for cross-border commuters, who sometimes resort to complex strategies to optimize their tax situation.
Extension of the tax recovery period in the event of false domicile
A key measure concerns the extension of the tax recovery period to ten years when the tax authorities detect false domicile abroad. This more stringent provision requires cross-border commuters to be transparent and justifies increased vigilance in managing their tax affairs.
Concerned by a notification of a tax recovery, affected taxpayers can initiate appeals through administrative or litigation proceedings. Cooperation between accountants, tax lawyers such as Leclerc Law Firm, and recognized organizations such as Eurojuris is often crucial to effectively defend their interests. Refund of Excess Tax on the Sale of Substantial Equity Interests
