Declare Your Property’s Occupancy by 1 July 2026 — What France Owners Must Do

French property owners face a firm July 1, 2026 filing deadline

If you own property in France, you must tell the tax authorities whether each dwelling was occupied, rented or vacant on 1 January — and in several cases you need to file a declaration by 1 July 2026. This requirement, introduced in 2023, is about how local taxes are calculated and can affect what owners pay for second-home levies or vacant-housing taxes.

This article explains the rule, who must act, how to submit the information, and what real estate investors and buyers should do to avoid surprises. We look at practical steps you can take right now, the documents you should keep, and the likely administrative follow-up to expect from the DGFiP.

What the occupancy declaration rule requires

Since 2023, owners of dwellings in France must report the occupancy status of each property to the tax administration every year. The status is reported as of 1 January each year and categories are straightforward:

• Occupied (owner or tenant occupying the dwelling)
• Rented (let out to a tenant at that date)
• Vacant (unoccupied on 1 January)

The declaration is made through the online service "Gérer mon bien immobilier" accessible from your secure personal space on impots.gouv.fr. You can also complete the declaration at other times of the year if a situation changes, but specific changes trigger an obligatory deadline.

Key legal timing you must note

• Since 2023: the annual requirement exists.
• File a declaration before 1 July 2026 if any of the conditions below applies.
• The look-back window for the 1 July 2026 deadline covers changes occurring between 2 January 2025 and 1 January 2026.

These dates are non-negotiable for the cases listed by the public service guidance.

Who needs to file by 1 July 2026

The tax administration spells out three clear cases where a declaration must be submitted no later than 1 July 2026:

• If the occupancy or conditions of use of one of your properties changed between 2 January 2025 and 1 January 2026 (for example: a change of tenant, a property becoming vacant, or a dwelling ceasing to be your main residence).
• If you failed to report a change in your real estate last year.
• If you have never previously filed a declaration for one of your properties.

Put simply: if anything about who was living in the property, whether it was let, or whether it was your main home changed in that timeframe and you did not declare it, you must act now.

How to file: online, via the tax return, or on paper

The DGFiP has tried to centralise the process and most owners will complete the declaration online. Options are:

• Online via "Gérer mon bien immobilier" in your secure personal space on impots.gouv.fr. This is the principal route and the service is designed for annual declarations and updates.
• When you file your annual income tax return online you can also report a change: the tax return process will automatically redirect you to the "Gérer mon bien immobilier" service when appropriate.
• By paper: if you have difficulty with digital tools, request and print the form titled "déclaration d'occupation des locaux par le propriétaire", complete it with the explanatory note, and submit it to your local public finance centre.

Support is available: call the assistance number for individual users 0 809 401 401 (non-surcharged call), Monday to Friday from 8:30 to 19:00, or contact your management department via secure messaging and choose the form “My real estate (occupation, declaration after work, description of the property)” then “Declaration of occupation of a real estate.”

Why this matters for taxes and for investors

The administration uses the declaration to determine which local taxes apply. Specifically, the declaration helps the DGFiP verify whether owners must pay:

• Council tax on second homes (taxe d'habitation / local second-home levies)
• Council tax on vacant housing
• The annual tax on vacant housing (taxe annuelle sur les logements vacants)

For property buyers and investors this is not trivial. The declared occupancy status directly affects:

• The local tax bill for a given property
• Whether a property is subject to surtaxes on vacant units
• The evidence the administration holds if it challenges a tax position later

From our analysis, owners who treat occupancy declarations as routine paperwork save themselves headaches. The worst scenarios I have seen involve investors who did not keep clear records of tenancy dates or main-residence claims; months or years later correcting the record is possible but it can trigger administrative queries and recalculations.

Practical checklist: what to prepare and how to act

To meet the deadline and reduce follow-up, prepare these items now:

• Record of occupancy on 1 January 2026 for each property (occupied, rented, or vacant).
• Dates of any tenancy changes between 2 January 2025 and 1 January 2026 (start and end dates of leases).
• Evidence that a dwelling changed from being your main residence (if applicable) — for example, change of address notifications or official documents.
• Property identifiers: address, cadastral references if you have them, and any property reference the tax office uses.
• Access credentials for impots.gouv.fr (your personal secure space) or contact details for a local representative who can manage the filing for you.

Steps to file before 1 July 2026:

1. Log in to impots.gouv.fr and access "Gérer mon bien immobilier."
2. For each property, confirm the occupancy status as of 1 January 2026 and record any changes that occurred within the 2 Jan 2025–1 Jan 2026 window.
3. If you cannot use the online service, download and complete the paper form "déclaration d'occupation des locaux par le propriétaire" and send it to your public finance centre.
4. Save copies and confirmations of the submission; keep all supporting documents for at least several years.

If you are an expat or a non-resident owner, we recommend ensuring your contact details with the DGFiP are current and naming a local contact who can receive mail and handle queries.

Scenarios investors should watch closely

• Change of tenant: if a lease ended and a new tenant started in 2025, that change falls in the window. File the declaration by 1 July 2026 to reflect the correct situation on 1 January 2026.
• Property became vacant: properties that switch to vacant status can face vacancy taxes; declare promptly.
• Dwelling ceased to be main residence: removing main-residence status can affect eligibility for certain taxes; document the date of that change.

We often advise investors to make a habit of reconciling tenancy records with the occupancy declaration once a year. Doing so avoids last-minute scrambles and reduces the chance of administrative corrections.

Risks and common pitfalls

The DGFiP uses the declaration to allocate local taxes. Failing to declare a change may not immediately trigger a fine in every case, but it can lead to:

• Incorrect tax assessments
• Administrative follow-up and requests for evidence
• Retroactive adjustments to tax bills if the administration concludes the original declaration was wrong or missing

Owners who rely on property managers must ensure the manager has actually submitted the declaration; the legal responsibility for the declaration remains with the owner. Keep copies of communications so you can show when and how the status was updated.

Support and contacts

• Phone support (individuals): 0 809 401 401, Monday–Friday 8:30–19:00 (non-surcharged).
• Online: log in to your secure personal space on impots.gouv.fr and use the "Gérer mon bien immobilier" service.
• If necessary, contact your local public finance centre and submit the paper form "déclaration d'occupation des locaux par le propriétaire".

The DGFiP also provides a secure messaging option through your personal tax space; use it if you need to send documents or ask detailed questions about a property.
