French Secondary Residence Tax Reforms 2026: What Non-Resident Owners Must Know
France's 2026 property tax reforms introduce mandatory digital occupancy declarations, new DPE energy requirements and stricter rules for foreign-owned homes in high-demand zones
2026 marks the biggest shift in French property law for non-residents in a decade. Here is what has changed and what you must do now.
2026 marks the most significant shift in French property law for non-residents in a decade. The French government has introduced a series of mandatory digital reporting requirements that affect every foreign property owner — whether you rent your property or not.
The three key changes in 2026
1. Mandatory GMBI Occupancy Declaration All property owners must declare the occupancy status of their French assets via the online GMBI portal before July 1st 2026. Failure to declare results in an automatic fine of €150 per property unit.
2. DPE Energy Rating Now Mandatory to Rent Properties rated F or G on the French energy scale are now banned from the rental market. Owners must obtain a valid DPE certificate (grades A to E) to legally rent their property. This applies to both long-term and short-term rentals.
3. Zones Tendues — Stricter Rules for Foreign-Owned Empty Homes The French government is actively targeting foreign-owned properties in high-demand urban areas (Zones Tendues) that appear vacant. Cross-referencing utility data, satellite imagery and tax declarations, authorities can now identify and fine owners of undeclared or misreported properties.
What non-residents must do before July 1st 2026
Complete your GMBI occupancy declaration accurately
Obtain a valid French tax number (Numéro Fiscal) to access the portal
Check your DPE energy rating if you plan to rent
Ensure your declared status matches your actual usage
The risk of doing nothing
Ignoring these obligations is no longer a viable strategy. French tax authorities have deployed automated systems that flag inconsistencies automatically. The cost of non-compliance — fines, backdated taxes, listing blocks — far exceeds the cost of getting compliant now.
