The declaration of real estate assets continues to be a critical fiscal obligation for property owners in many jurisdictions, with particular emphasis set for the year 2025. Following the removal of the council tax on primary residences, tax authorities now mandate owners to accurately report the occupancy status of their properties, which may include primary residences, secondary homes, and rental units.

Non-compliance or inaccuracies in these declarations can lead to significant penalties.

As of 2025, all property owners—whether individuals, businesses, or real estate investment companies—are required to submit detailed property declarations.

This obligation covers various types of real estate, including residential homes and vacant properties.

Tax authorities are tasked with ensuring that the reported use of properties correlates accurately with their records.

Any changes in occupancy or usage must be reported to avoid sanctions.

Notable changes for 2025 include a greater consideration of secondary residences and vacant units, which now require specific reporting.

Owners must also disclose the precise number of main rooms within their properties.

Furthermore, tighter controls are introduced regarding the consistency between reported occupancy and declared rental income.

Tax authorities will have the capability to cross-reference declarative data with property tax records and energy supplier information to detect potential discrepancies.

To fulfill the property declaration requirement correctly, individuals should access their personal accounts on the tax administration website, specifically under the section labeled 'Manage my real estate assets.' The following information must be accurately reported:
- The type of use: principal residence, secondary home, rented (furnished or unfurnished), or vacant property.

- The exact number of main rooms in the property.

- The identity of occupants in instances where the property is rented.

For those without online access, this process can alternatively be completed using paper forms by reaching out to their local tax offices.

It is essential for owners to declare their primary residence even if it is exempt from council tax.

Correctly indicating this occupancy status is vital to avoid errors in tax records.

Failure to declare can lead tax authorities to classify the property incorrectly, potentially resulting in undue taxation.

Common pitfalls to avoid during the property declaration process include:
- Failing to report changes in property status, such as sales, inheritances, or new rental agreements.

- Incorrectly reporting the number of rooms, which could lead to reclassification.

- Not properly identifying the right occupants, especially in cases of shared housing or vacation rentals.

- Missing the declaration deadline, which is set for June 30, 2025.

Inaccuracies or failures in the declaration can incur fines, with penalties starting at €150 per property.

Given the increased scrutiny and the heightened requirements for 2025, property owners are advised to take meticulous care when completing their declarations to ensure compliance and avoid unnecessary financial penalties.
