French Wealth Tax (ISF) and French Property Wealth Tax (IFI)

This page outlinesupdate 2009
- Taxable assets
- Wealth tax rates
- Wealth tax penalties
- Wealth Tax Optimisation
- Tax ceiling (75% income)

As a high net worth individual - either resident or with significant property in France - it is critical to understand and track the changes in French wealth tax - called ISF (Impôt sur la Fortune) until 2017.

Since 2018, wealth tax has been limited to property assets (net of associated loans) and renamed IFI (impôt sur la fortune immobilière) ie French “Property Wealth Tax”.

This clearly represents a significant reduction in wealth tax for a number of French residents - and did not go unnoticed by the Gilets Jaunes protesters. However, President Macron has stood firm on the lower IFI wealth tax - refusing to bring back the higher ISF and explaining that France needs wealthy individuals to create new businesses and thus bring down unemployment.

The IFI rules and rates for 2023 have not been changed - and still include a 30% reduction for the main residence.

The tax ceiling still applies. Whilst this may not seem to be of interest at first sight (capping taxes at 75% of income), by living as far as possible off capital (eg withdrawing from a wrapper such as an Assurance Vie), your “taxable income” will be minimal - and your total taxes (including IFI) cannot exceed 75% of that minimal income.


French residents are liable to wealth tax (IFI) on their worldwide properties (main home, second homes, rented properties, ...). Non-residents are only liable for wealth tax on assets physically situated in France.

Please note that residency is defined by French law and is not simply a matter of being present for 183 days.
For example, those whose French home is effectively their main home (used for family gatherings or where more time is spent that in any other of your permanent homes) would be normally considered French resident - even if also tax-resident in another country.

There is a partial exemption for five years from French wealth tax (IFI) for most people moving to France. This exemption applies only to assets outside France.

Assets must be consolidated for all members of the household. Couples must make a joint declaration whether married or not. Assets held by children below 18 years of age must also included.

Assets liable to the new IFI wealth tax are now limited to land & buildings (Principal & secondary residences, rental property, ...). Financial investments, jewellery, furniture, cars, boats, etc are now all excluded.

Even if you are not the direct property owner, simply having the right to live somewhere can be enough to make you liable on the capital value - as well as any properties owned via a Trust of which you are a beneficiary.

If you own shares in a property company (eg SCI - Société Civile Immobilière), your wealth tax declaration must include the current value of the underlying property.


French Wealth Tax  is payable by those with net assets above 1300000€ - evaluated as at 1st January.

To calculate the tax, add up the total value of assets for the household and deduct all outstanding debts and overdrafts as at 1st January

For 2022, the following bands apply (identical to the bands for 2021):

    Assets (k€)                   ISF Rate applicable
       0 - 800                                    0%
       800 - 1300                             0.5%
       1300-2570                              0.7%
       2570 - 5000                            1.0%
       5000 - 10000                        1.25%
       above 10000                          1.5%

There is a reduction for those with assets just inside the entry level (1.3-1.4M€). The formula for this reduction is 17500€ - (1.25% x P) where P is the value of assets. The starting value for IFI (ie assets worth 1.3M€) therefore becomes 1250€ instead of 2500€.

French residents declare their wealth in the specific IFI section of the normal (2042) annual income tax return. You should then normally receive an IFI “avis” (statement) around August, September or October- payable by the 15th of the following month.


French tax authorities carry out regular controls to determine if wealth tax declarations have been correctly submitted. Specific events, such as sales or inheritance of high-value property, can also lead to a tax control.

If the authorities consider that you have underpaid wealth tax, they will challenge not only your last declaration - but may go back up to 10 years. The time available for the tax authorities to question valuations or omissions is variable:

   Assets in France
   - 3 years if the asset description on the wealth tax form was sufficiently precise requiring no further research
   - 6 years if the description was insufficient or omitted
   - 10 years if there was intentional fraud

   Assets outside France
   - 3 years if the asset description on the wealth tax form was sufficiently precise requiring no further research
   - 10 years in all other circumstances

If the authorities consider that you have underpaid wealth tax, they can claim
- the additional wealth tax that should have been paid
- annual interest on the unpaid wealth tax (approx 4% pa) as from the initial due date
- a penalty of 10% (on the additional tax due) for late payment
- an uplift of 40% (on the additional tax due) if they consider that you have not been of good faith (mauvaise foi)
- an uplift of 80% (on the additional tax due) if they consider you have used fraudulent techniques to hide assets

The above is only an outline of our understanding of the key rules. If you receive correspondance from the tax authorities challenging your declarations it is always important to react quickly and take legal advice.


1. Know your rights.

Don't over estimate property values, for example:
- As a French resident, for your principal residence, you can deduct 30% from comparable sales value
- For each rental property you can deduct an amount representing the reduction in value due to the property being occupied at the time of sale and the potential difficulty of obtaining free occupation - but no percentage is specified in any formal texts.

Ensure you indicate any assets used wholly or partly for company or professional purposes as “exonéré” if they meet the appropriate conditions.

All outstanding loans formally linked to the declared properties (eg registered mortgages) and relating to purchase, improvement and maintenance work can be deducted, subject to the following restrictions
- interest only loans are deductible at the capital value multiplied by the proportion of outstanding years to total years
- loans must be at arms length (with no direct or indirect links to you or your immediate family). Loans to close family (parent, sibling, ...) are allowed if the loan meets normal conditions with regular reimbursements.
- if total gross property assets exceed 5M€, total deductible loans cannot exceed
---60% of the gross property assets
---plus half of any excess loans above the 60% limit.

Do declare all liabilities outstanding on the evaluation date (1st January) and relating to the declared properties, such as :
- purchase, repair, and maintenance costs - based on unpaid invoices at the year end
- property taxes based on ownership at 1st January (other than those payable by the occupant) - such as taxe foncière and taxe sur les locaux vacants (but NOT taxe d’habitation) using the amounts shown on the prior year notices (avis)
- outstanding charges de copropriété (from the last quarter of the prior year)

These items reduce your net taxable assets.

2. Tax ceiling (plafonnement ISF) at 75% of income

There is a wealth tax cap known as “plafonnement ISF” (similar to the previous Bouclier Fiscal) so that total French & Foreign taxes should not exceed 75% of income. The calculation compares prior year taxable income to the income & social taxes due on that income - plus current year wealth tax. If the ratio is over 75%, the wealth tax is reduced (potentially to zero).

Retired or semi-retired high net worth individuals should therefore consider living off capital - and leaving income & gains to build up inside private investment companies or capital wrappers (such as Assurance Vie).

Despite two attempts by the government to take unrealised “wrapper” income into account, the Conseil Constitutionnel has confirmed that no interest or gains received within an assurance vie are taken into account in the 75% calculation.

3. Start transferring assets.

One of the most effective ways to reduce ISF is to spread assets amongst your descendants once they become adult - though do be aware that French gift taxes apply to any French resident donor or beneficiary.

Rather than making a full gift, you can also make “temporary gifts” known as usufruit temporaire.

If well organised, the family will pay lower rates or avoid IFI altogether.

If badly organised, you could end up paying high levels of gift tax instead.

Careful planning is therefore required and we suggest discussing with professional advisors at an early stage.

LOANS within SCI’s held by NON-RESIDENTS

Loans by non resident individuals or companies made to French property companies (SCIs) are no longer deductible when calculating the value of the property shares for wealth tax purposes.
