As concerns about purchasing power and the financial stability of French households persist, the Real Estate Wealth Tax (IFI) stands out as a real point of contention. This specific tax, established in 2018, targets exclusively net real estate assets exceeding 1.3 million euros, thus becoming a growing burden for an increasing number of taxpayers. Despite its limited share in the national budget, the IFI generates significantly increasing tax revenue, reflecting the continuous rise in real estate values in strategic areas such as Paris or the French Riviera. In response to this situation, many families are mobilizing to better understand, anticipate, and sometimes challenge this taxation, thereby strengthening the public debate on tax fairness.
The complexity of the system and the constant evolution of the rules drive taxpayers to seek expert support, whether from tax lawyers, wealth advisors, or advocacy associations such as Contribuables Associés. These actors play a key role in clarifying the mechanisms and defending household interests against a tax system sometimes deemed too strict. For holders of significant real estate assets, mastering the IFI declaration, identifying possible exemptions, and building tax optimization strategies are essential steps to reduce the tax burden without violating the law.

The essential basics of the Real Estate Wealth Tax: operation and scope
The Real Estate Wealth Tax, which has replaced the ISF since 2018, aims exclusively to tax real estate assets held by individuals. Only properties located in France and whose net value exceeds 1.3 million euros as of January 1st of the tax year fall within the scope, whether the taxpayer is a tax resident or not. This specificity refocuses taxation on a precise segment of wealth and thus removes the consideration of securities which characterized the former ISF.
The calculation method is based on a progressive scale, with a rate ranging from 0.5% on the bracket immediately above the entry threshold up to 1.5% beyond 10 million euros. This progression happens in six distinct steps for the highest levels of wealth, which complicates the declaration and the understanding of the amounts due.
| Net value of real estate assets | Applicable rate |
|---|---|
| Up to €800,000 | 0% |
| €800,001 – €1,300,000 | 0.5% |
| €1,300,001 – €2,570,000 | 0.7% |
| €2,570,001 – €5,000,000 | 1% |
| €5,000,001 – €10,000,000 | 1.25% |
| Over €10,000,000 | 1.5% |
Debts can reduce the taxable value, however their nature is strictly examined by the administration. Loans contracted to finance a real estate property are deductible, while certain zero-interest loans or those linked to operations not directly associated with real estate are not taken into account. This distinction is decisive for owners seeking to minimize their taxable income for the IFI. In case of doubt or dispute, seeking advice from a specialized tax lawyer is highly recommended.
Finally, exemptions play an important role in adjusting the taxable base. The 30% allowance on the primary residence, exemption of professional properties, and certain reductions related to woodlands and forests are essential levers which, depending on the wealth profile, can considerably lighten the bill. Their implementation requires thorough knowledge of tax law and precise valuations.

Declarations and common pitfalls during IFI taxation: vigilance required
The IFI declaration regularly causes problems for taxpayers, particularly due to the tax threshold set at 1.3 million euros. This threshold, although significant, becomes accessible for an increasing number of households due to the constant rise in property prices in several strategic regions. Added to this is complexity related to valuation and exemption rules, sources of many errors that can lead to costly tax adjustments.
The first difficulty lies in the precise valuation of assets as of January 1st of the tax year. The market value requires rigorous estimation, often subject to controversy. Foreign properties, sometimes omitted through ignorance, must also be included in the declaration under penalty of sanctions. Moreover, some assets benefit from partial or total exemptions, such as historic monuments or professional properties, which require strict supporting documents.
Another subtle aspect concerns allowances. For example, an owner of their primary residence can deduct 30% of its taxable value for the IFI. Similarly, a particular discount of 17,500 euros minus 1.25% of the taxable value is granted for assets between 1.3 and 1.4 million euros. This mechanism significantly eases the tax burden for taxpayers close to the tax threshold, but its application is often poorly mastered.
- Frequent omissions of assets held abroad
- Poor estimation of market value as of January 1st
- Non-application or incorrect application of allowances and exemptions
- Inappropriate or undocumented debt deductions
- Late or incorrect declarations exposing to penalties
An anecdote illustrating these difficulties is that of Mr. and Mrs. Dupont, owners in Nice, who, convinced they would not reach the threshold, faced a substantial tax reassessment during an audit. Their main mistake was omitting a furnished rented apartment downtown and not benefiting from the allowance on their primary residence, due to not properly updating their declaration. This type of situation pushes taxpayers to strengthen their recourse to experts to secure their declaration.
Tax optimization and strategies to limit the weight of the IFI on your wealth
For many holders of significant real estate assets, the IFI represents a substantial tax burden, calling for financial and legal optimization strategies. These methods, legal and often complex, aim to reduce the taxable base while participating in active wealth management.
Among the most widespread strategies is first the transformation of certain assets into professional assets. These are fully exempt from IFI, provided they are used within the framework of a commercial, industrial, craft, or agricultural activity. This option requires however thorough documentation and careful monitoring of the conditions of application.
Another major lever is the use of Civil Real Estate Companies (SCI). By structuring one’s assets through an SCI, the owner benefits from some flexibility in the distribution of shares, in the transmission to heirs, and can sometimes benefit from more favorable taxation by optimizing the composition of the held assets. In some cases, this also facilitates the integration of specific allowances.
Donations to recognized public interest organizations also allow a direct reduction of the amount owed under the IFI. These donations entitle to a tax reduction of up to 75% within the limit of 50,000 euros, constituting an important lever to alleviate the tax burden while supporting a social or environmental cause.
| Strategy | Impact on the IFI | Points of vigilance |
|---|---|---|
| Conversion into professional assets | Total exemption from IFI taxation | Strict justification of professional use |
| Setting up a family SCI | Optimization of transmission and tax distribution | Compliance with tax transparency and document management |
| Donations to eligible organizations | Tax reduction up to 75% | Verification of beneficiary eligibility |
| Tax-advantaged investments (woodlands, forests, monuments) | Partial exemptions depending on asset type | Compliance with legal and administrative conditions |
Finally, geographic diversification of wealth, especially abroad, is attracting increasing interest. Holding shares in companies not taxable to the IFI can significantly reduce taxable income, even though this requires increased vigilance regarding tax audits and international agreements.

Increasing economic pressure and debates around a necessary reform of the IFI
Although the Real Estate Wealth Tax contributes to the national fiscal effort, it fuels numerous controversies about its fairness, its impact on the mobility and transmission of assets, and the perception of a sometimes excessive burden among liable taxpayers. This pressure becomes particularly tangible for households with mostly immobilized wealth, with rental income often insufficient to cover the tax charge.
In this context, many call for a thorough reform of the system in order to better balance tax fairness and encouragement of real estate investment. The emergence of associations like Contribuables Associés testifies to this citizen mobilization aiming to defend the interests of taxpayers facing a tax system perceived as punitive. Public discussions also emphasize the need to simplify declaration procedures and to ensure greater transparency concerning exemptions and allowances.
The stakes are therefore multidimensional: they combine the direct economic impact, family wealth management, and a social dimension linked to national tax cohesion in a context where the overall tax pressure continues to grow.
- Rental income often lower than the tax charge
- Difficulty monetizing assets without selling them
- Need for a simplifying and equitable reform
- Strengthening fiscal controls and increased vigilance
- Citizen mobilization around defending taxpayers’ rights
