Calculate the Impôt sur la Fortune Immobilière on net real estate assets above the €1.3 million threshold.
What counts for IFI (Impôt sur la Fortune Immobilière)?
IFI applies to net real estate assets including: residential and commercial property, land, property held through SCI or SCPI, real estate portion of OPCI, and property held abroad. It excludes financial investments, business assets used professionally (biens professionnels), and forests/rural land with special exemptions.
What are the IFI thresholds and rates?
IFI is triggered when net property assets exceed €1,300,000, but tax is calculated from €800,000: 0% up to €800,000; 0.50% from €800,001 to €1,300,000; 0.70% from €1,300,001 to €2,570,000; 1.00% from €2,570,001 to €5,000,000; 1.25% from €5,000,001 to €10,000,000; 1.50% above €10,000,000.
What exemptions are available for IFI?
Key exemptions include: primary residence receives a 30% reduction on its value; business real estate (biens professionnels) is fully exempt; forests and rural land benefit from a 75% exemption; historic monuments may qualify for partial exemption. Debts related to taxable property can be deducted.
When and how is IFI paid?
IFI is declared with your annual income tax return in May/June. It is self-assessed — you calculate the amount yourself. Payment is due by the same deadlines as income tax. If the amount exceeds €300, online payment is mandatory. A décote (smoothing) applies for net values between €1.3M and €1.4M.

How the Impôt sur la Fortune Immobilière taxes property wealth
How does this work in France?
Wealth Tax (IFI) in France follows specific French rules set by the DGFiP and Code Général des Impôts. The system is designed to balance social protection with economic activity. Understanding the rules helps you plan your finances and avoid surprises at tax time.
What are the key rates and thresholds?
French rates and thresholds are updated annually in the Loi de Finances. Income tax brackets, social charge rates, and benefit thresholds all change each January. Always check the latest figures on impots.gouv.fr or service-public.fr. Using outdated rates can lead to incorrect calculations and unexpected tax bills.
How does this affect your annual tax return?
All income and deductions must be reported on your déclaration de revenus annuelle, filed online at impots.gouv.fr by mid-May. The tax office cross-references your declaration with employer data (DSN), bank reports, and other sources. Errors can trigger a contrôle fiscal (tax audit) with penalties of 10-40% of undeclared amounts.
What records should you keep?
French law requires keeping all financial records for at least 6 years for tax purposes and 10 years for commercial documents. This includes invoices, receipts, bank statements, contracts, and payslips. Digital copies are accepted if they are legible and stored securely. The fisc can audit any period within these timeframes.
Where can you get help?
For tax questions, contact your SIP (Service des Impôts des Particuliers) or SIE (Service des Impôts des Entreprises). The service-public.fr website has detailed guides. For complex situations, hire an expert-comptable (chartered accountant) — fees range from €500 to €3,000/year. Trade unions (syndicats) and the CAF also provide free advice on social benefits.
What penalties apply for errors?
Late filing: 10% surcharge plus 0.2% per month of interest. Deliberate understatement: 40% penalty. Fraud: 80% penalty plus potential criminal prosecution. If you discover an error, file a déclaration rectificative as soon as possible — voluntary correction reduces penalties. The fisc appreciates good faith and transparent communication.
