Remote work abroad: French employee tax and employer obligations in 2026

Allowing a French employee to work remotely from Lisbon, Brussels, Montreal, Dubai or Casablanca looks straightforward. For the employer, it actually combines payroll, tax, social security, immigration, insurance, local labour law and, in some cases, a permanent establishment exposure that engages the French company. The topic has changed nature since 2022: post-Covid generalisation of remote work, entry into force on 1 July 2023 of the EU framework agreement on cross-border telework (signed to date by 21 Member States including France, Germany, Belgium and Spain), OECD 2017 doctrine on permanent establishments updated in 2023, and French Conseil d'Etat case law on article 4 B of the French Tax Code make a structured analysis unavoidable before departure. At Hayot Expertise, we regularly meet executives who only discover those obligations six to twelve months after an employee has left, when the first social or tax filing reveals a coverage gap, a local contribution due or a taxable presence created. The 2026 golden rule is simple: no international remote work authorisation should be signed without a written, dated qualification file validated by payroll and tax.

Remote work abroad is qualified along four cumulative dimensions: duration (one-off, partial, durable, de-facto expatriation), country (EU/EEA/Switzerland, treaty country, non-treaty country), employee status (French or foreign tax resident, EU or non-EU national) and function nature (support, technical, sales, executive, contract signing). On the social security side, Regulation (EC) No 883/2004 sets the principle of unique applicable law: an employee in principle falls under the social security of the country where work is physically performed, unless under detachment (article 12, capped at 24 months) or the telework framework agreement (up to 49.9% of working time in the country of residence, provided both States are signatories). The A1 certificate issued by URSSAF Caisse Nationale evidences continued French social security affiliation. On the tax side, article 4 B of the French Tax Code defines French tax residence through three alternative criteria (home or principal stay, main professional activity, centre of economic interests); bilateral treaties then apply the 183-day rule and the activity centre test to break ties on dual residence. On the employer side, the OECD (2017 Model updated in 2023) recognises that the physical presence of an employee performing key functions in another State may, in some cases, create a permanent establishment of the French company, triggering local taxation of an attributable share of profit. The observed risk range with our French SME clients in 2026 spans EUR 0 (well-framed situation) to over EUR 80,000 in catch-up (local social contributions, withholding tax, local profit tax, penalties) for a single uncovered employee over 18 months.

• Destination country, expected duration, day-by-day calendar and actual telework address (lease or hosting evidence).
• Employee administrative status: nationality, residence permit, right to work in host country (digital nomad visa, work permit, EU exemption).
• Functions actually performed: back-office support, development, sales, negotiation, signing, representation – each category carries a different risk profile.
• Social security: A1 form request via URSSAF portal (4 to 6 weeks lead time), choice between article 12 detachment, article 13 multi-activity or article 16 telework framework agreement.
• Employee tax: keep or lose French tax residence (article 4 B CGI), PAS French withholding, application of bilateral treaty, possible dual filing.
• Payroll: contractual decision (temporary amendment, mission letter, local contract, EOR), keep French payslip or not, possible gross-up for additional contributions.
• Employer: permanent establishment analysis under OECD article 5 (fixed place, duration, authority to conclude), possible local registration, employer withholding, services VAT.
• Insurance and health: international medical cover, CFE outside EU, complementary disability cover, extended professional liability, repatriation.
• Local labour law: working time, leave entitlements, mandatory provisions (Spain riders law, Portugal direito a desconexão, German BetrVG), discipline and dismissal rules.
• GDPR and IT security compliance: international data transfers, encrypted remote access, corporate equipment, signed remote work charter.

Anonymised case study from a recent assignment. A French software publisher SME (42 employees, EUR 6.8m revenue, Paris 8th arrondissement headquarters) allowed in September 2024 its customer success lead to work remotely from Barcelona six months a year, without formalising the file. The employee, originally a French tax resident, moved his family to Spain in March 2025. Cumulative consequences as of Q1 2026: (1) reclassification of his tax residence by the Spanish tax authority under the France-Spain treaty of 10 October 1995 (stay > 183 days, permanent home in Spain, centre of economic interests shifted); (2) retroactive affiliation to Spanish Seguridad Social over 12 months (employer contributions estimated at 31.2% of gross salary i.e. approximately EUR 22,400 on a EUR 60,000 gross); (3) obligation for the SME to register with the Tesorería General de la Seguridad Social and the Hacienda as employer without establishment, with IRPF withholding (24% to 47% by bracket); (4) unfavourable permanent establishment analysis because the employee was also handling Iberian key-account prospecting, creating a Spanish corporate tax exposure on the attributable margin. Total catch-up cost: EUR 41,800 of social contributions and penalties, EUR 8,600 of local legal and accounting fees, EUR 14,000 of Spanish corporate tax provisions pending double-taxation discussion with the French administration. The same employee, properly framed from the start with a CLEISS telework framework agreement capped at 49% and a contractual amendment forbidding sales signing in Spain, would have cost the company zero additional charge.

Our method at Hayot Expertise rests on three complementary pillars that we deploy for every executive consulting us on international remote work. First pillar, the written qualification grid: a matrix crossing country, duration and function, with an automatic decision "authorised without formality", "authorised under A1", "authorised under framework agreement", "switch to EOR" or "motivated refusal". This grid becomes an HR policy signed by management and annexed to the internal rules. Second pillar, the dated evidence file before departure: copy of the A1 or framework agreement request filed with CLEISS, contractual amendment specifying the authorised country, maximum duration, express ban on signing or negotiating locally for non-sales functions, early return clause in case of regulatory change, and a monthly presence calendar to be completed by the employee. Third pillar, shared payroll-tax follow-up: we coordinate with the payroll manager (internal or outsourced) quarterly day verification, production of correct payslips, possible DAS2 reporting or adapted PAS withholding. Registered with the Ordre des Experts-Comptables de Paris Île-de-France, we work in network with local correspondents in 18 countries (Spain, Portugal, Belgium, United Kingdom, Germany, Switzerland, Italy, Netherlands, Morocco, Canada, United States, United Arab Emirates, Singapore among others) to validate the host-country reading. Our conviction is that international remote work belongs to HR internal control, not to ad-hoc reactions to employee requests.

The most underestimated risk in 2026 is the involuntary creation of a permanent establishment of the French company in the telework country. Article 5 of the OECD Model revised in 2017 and refined in 2023 retains two main criteria: the fixed place of business (a home can suffice if activity is performed there regularly and continuously, French Conseil d'Etat Conversant ruling of December 2020) and the dependent agent habitually exercising the authority to conclude contracts in the name of the company. Concretely, a salesperson prospecting and negotiating abroad, an executive signing purchase orders or customer framework agreements remotely, a manager representing the company in local strategic meetings can be enough to characterise a permanent establishment, even without rented office or local registration. Consequence: the French company must declare in the host country the share of profit attributable to that establishment, pay local corporate tax, sometimes local VAT, and then ask France to eliminate double taxation (treaty credit or exemption depending on the convention). Two other frequent pitfalls: false tax residence, when the company keeps applying French PAS withholding while the employee has become a foreign tax resident (PAS must stop when residence shifts, except for French-source income); and lack of social cover, when the employee works outside EU without CFE or private insurance, and an accident or hospitalisation engages the employer's civil liability under his safety obligation (article L.4121-1 of the French Labour Code).

• Adopt a written international remote work policy annexed to internal rules, validated by the works council where applicable, listing authorised countries, maximum durations and eligible functions.
• Deploy the "country × duration × function" qualification grid with automatic decision and mandatory signature of a temporary contractual amendment before any departure.
• Appoint an HR + CFO duo responsible for follow-up (A1 requests, framework agreements, presence calendars, social and tax filings country by country).
• Require prior declaration of any remote work abroad lasting more than 5 consecutive working days, with mandatory approval before departure.
• Track monthly presence days by country through a shared tool (timesheet export, VPN connection data, HR platform).
• Define a clear switching threshold beyond which the company refuses, proposes a local contract, uses an employer of record (Deel, Remote, Velocity Global) or organises a formal detachment.
• Document in writing, in the amendment, an express ban for non-sales functions to negotiate or sign from the host country, in order to neutralise the permanent establishment risk.
• Annually test the map of international teleworkers and coordinate it with the chartered accountant to anticipate the 183-day and 49.9% thresholds.

• EU framework agreement on cross-border telework (1 July 2023): signed to date by 21 Member States including France, Germany, Belgium, Spain, Italy, Netherlands, Portugal, Switzerland, Luxembourg, Austria. Cap of 49.9% of working time in the country of residence, single employer required.
• Regulation (EC) No 883/2004: article 12 (classic detachment capped at 24 months), article 13 (multi-state activity), article 16 (derogations including the telework framework agreement). Outside the EU, bilateral social security treaties apply (France has signed more than 40).
• Article 4 B of the French Tax Code: three alternative criteria of French tax residence (home or principal stay, main professional activity, centre of economic interests). Losing one criterion may suffice to lose tax residence if the treaty confirms it.
• Treaty 183-day rule: physical presence > 183 days over 12 rolling months in a treaty State in principle switches tax residence, with treaty-specific exceptions.
• Permanent establishment risk under OECD article 5: an employee's home can constitute a fixed place; a dependent agent signing contracts engages the company. French Conseil d'Etat Conversant ruling of 11 December 2020.
• Caisse des Français de l'Étranger (CFE): voluntary affiliation is essential for employees teleworking outside EU/EEA/Switzerland, on top of private insurance and international medical cover.
• Employer safety obligation (article L.4121-1 French Labour Code): also covers teleworkers abroad, requires country risk assessment (health, security, climate, infrastructure) and documented preventive measures.
• French law applicable to the contract: can be maintained through express clause (Rome I Regulation) but mandatory provisions of the country of performance apply (working time, leave, minimum wage, dismissal protection).
