French tax authorities now use AI algorithms to detect undeclared properties. Here's what non-resident owners must know in 2026.
As of 2026, the French Tax Ministry has deployed automated AI algorithms that cross-reference electricity consumption, water usage, and satellite imagery with your mandatory GMBI declarations.
What triggers an audit?
If your French home appears active but is declared as vacant, or if your occupancy dates don't match your utility usage, an automated audit is triggered automatically.
Why non-residents are most at risk
For non-resident owners, this means receiving a registered letter in French that you might not see until it's too late. Fines start at €150 per unit and can escalate quickly if left unresolved.
