This tax trap that awaits all the owners (and not just the rich)

Did you think you did the best by buying properties? Bad news: in 2025, it is not your mortgage to wake up at night, but the tax administration. Since 2023, a rule spent in the vintage forces you to declare what you do with your accommodation every year. Forgetting? 150 € well for good. And no, it's not a joke. It's a new gas factory … with your teeth.

The bureaucratic trap that is expensive

It is simple: any owner, who lives in a main residence or rents a study in Marseille through Airbnb, must declare the exact use of his accommodation. Inhabited, vacant, lent for free, rented … the taxi wants to know everything. And be careful: even secondary residences or empty accommodation are in the sights.

The tax administration justifies this measure according to the need «to adapt taxes to real use». Translation: they want to trace every square meter scarcely declared to optimize their collection. And you have to connect to a shaky platform to chew their work.

Yes, tenants can also be captured

What nobody tells you: if you are a tenant of a second home or a long period furnished, you too can be worried. Do you think you are in your holiday home in Biarritz? The tax authorities can ask you for a statement. Otherwise ? A tax on surprise housing.

Why this absurdity? Because taxation changes and everything that seems to be an address not sent becomes suspicion. It is not tax optimization, it is surveillance. And it goes even further.

An automatic and ruthless fine

The administration no longer takes the gloves. € 150 End of unbelieved or poorly informed accommodation. Whether it's oblivion, a bad controlled box or an unaware of a occupant change, the addition can rise quickly. Especially if you have several goods or if you lend yourself to relatives.

And since everything is digital, it is the algorithm that triggers the sanctions. No human being to listen to your excuse. No negotiation possible. It is a robotic taxation in all its coldness.

Multipropri -proptripts in the viewfinder

Do you have several goods? Welcome to the kitchen. Of course, a delegation system allows you to entrust the declaration to third parties … but it is still necessary to trust. The slightest forgetfulness can cost you hundreds of euros. And believe me, the administration is not missing.

Many investors find themselves managing dozens of statements to avoid being pinched. In the meantime, they must juggle rents, insurance, energy diagnostics and now, it is absurd annual statements.

An online platform, real bugs

«Manage my property»: a platform that should simplify life. Actually? Bugs, false pre -riempitis information and efficient zero assistance. Result: you have to check everything, correct everything, validate everything. What if you make mistakes? Too bad for you.

The most infuriated? You are responsible for the information that the administration has sometimes lost from the beginning. Has the right to make mistakes. You, no.

Because this is only the beginning

This new system is only a prelude. The final goal? Shape the real use of your inheritance. Cross your Linky invoices, your DPE, your income declarations … the state wants a 360 ° view of your goods for a better tax.

Tomorrow, property tax may vary depending on the rental performance. The housing construction tax could return to the «underutilized» accommodation. See the advice? Each declaration is a tax screwdriver in preparation.

How not to be deceived

1. Check each property As if it were a declaration of income. A forgetfulness will not be forgiven.
2. Don't trust any pre -Ryded information : Check everything.
3. Do it now : Wait for the last day, you will have the carafe website and a fine in a bonus.
4. Consult a professional If you have several goods: the cost of the advice is better than that of a sanction.

It is not pessimism, it is a budget realism.

What you should remember

The declaration of the goods is not a formality. It is a masked tax conformity test. And as usual, it's up to you to do the job, while the administration is waiting to be able to punish you at the first false step. Because a forgotten euro, a euro works against you.

So yes, it is unfair, ineffective and poorly messed up. But if you don't play according to their period, you lose. Foul. Check everything. What if you find it absurd? Talk, share the information. Because this system is mainly due to our silence.
