Develop an Endometriosis Expert Center
75% credit against your IFI wealth tax.
100% in support of endometriosis treatments.
Endometriosis, the leading cause of infertility, is a complex chronic condition that affects between 1.5 and 2.5 million women in France. Endometriosis frequently causes debilitating pain and/or digestive and urinary symptoms, thereby considerably altering quality of life. Care pathways are often long, sporadic and unequal depending on the region, and the condition remains under-diagnosed today.
As part of a national campaign to combat endometriosis, the Endometriosis Expert Center of the American Hospital of Paris aims to offer each patient comprehensive, fully personalized care adapted to the severity of the condition.
Using a multidisciplinary collaborative strategy, our center will build synergies among experts – who include specialized radiologists, OB-GYN surgeons, reproduction specialists, digestive and urologic surgeons and coordinating midwives – to guarantee an approach based on medical excellence. 1,000 patients will be treated annually in our day hospital.
Project aims:
- Guarantee a fluid, rapid, personalized and coordinated care pathway;
- Mobilize a multidisciplinary team of physicians and allied health professionals (physiotherapists, dieticians, sexologists) around a common endometriosis culture;
- Position the new center as a key player in research and organizational innovation dedicated to endometriosis;
- Expand the center’s renown both nationally and internationally.

Endometriosis is a condition that steals years of life from those affected by it: years of pain, diagnostic delays and injustice for millions of women. It concerns all of us: our daughters, our wives, our mothers, who must cope with pain, infertility and deeply disrupted lives.
I am committed to making the American Hospital of Paris a global beacon in endometriosis treatment, providing quintessential care in a unique, inspiring and innovative environment. Driven by the excellence of our French-American medical culture, the center will combine a dedicated day hospital, consultations with international experts, precision diagnostic imaging, state-of-the-art surgical techniques and scientific research programs while bringing the discipline to the fore in academia.
We are going to create an identifiable leading structure capable of offering fluid, personalized and continuous care pathways, providing treatment, expertise, research and transmission in a single care environment, with the ambition of achieving the highest level of excellence. This vision of endometriosis is driving us toward a whole new approach aimed at making a deep and enduring impact on the lives of thousands of women, families and couples who have been in pain for too long.”

Frequently Asked Questions
How do I know if I am subject to the IFI wealth tax on real estate assets?
You are subject to the French wealth tax on real estate assets (IFI) if the net value of your real estate assets exceeds €1,300,000. The value of the assets being reported is their estimated value on January 1st of the tax year in question. Your primary residence always benefits from a 30% allowance. The assets taken into account in the IFI tax base are those owned by all members of the tax household combined.

How do I calculate my IFI tax credit?
If you want to reduce your IFI tax to a minimum, simply calculate as follows: IFI/0.75 = your donation amount. Use our calculator to determine how much IFI tax credit you can receive for your donation.
When do I have to make my donation to receive my IFI tax credit?
To qualify for a 2026 IFI tax credit, your donation must be made before your tax filing deadline. The date varies depending on the French department you live in and whether you file by paper or online.
How do I make a donation?
You can make your donation by:
- Bank card via our website – it's easy and secure.
- Check made out to the American Hospital of Paris: download the donation form here and return it to:

If you encounter any difficulties, please contact our Major Gifts department at + 33 1 46 41 27 97.
How do I report the tax credit I received after making my donation?
You must mention your donation in the section “Réduction d’impôt pour des organismes d’intérêt général établis en France” (tax credit for charitable donations in France) in Box 9 of Form 2042-IFI (supplementary income declaration). Also be sure to store the tax receipt we send you in a safe place, in case you are asked to present it to the tax authorities.
Can I combine an IFI credit and an income tax credit?
You cannot receive the maximum tax credit against your IFI wealth tax and your income tax simultaneously, but you may choose to split your donation amount between the two taxes.
For example, if you donate €15,000, you may divide this amount between your IFI wealth tax and your income tax as follows:
→ IFI wealth tax: €10,000 for a €7,500 tax credit (€10,000 X 75%)
→ Income tax: €5,000 for a €3,300 tax credit (€5,000 X 66%)
Your tax credits total €10,800, meaning your donation actually costs you only €4,200.
If I qualify for a tax credit that exceeds the IFI tax I owe or exceeds the maximum credit allowed, can I carry over the surplus?
If you quality for a tax credit that goes over the maximum credit allowed or exceeds the amount of IFI tax you owe, you cannot carry over the surplus to reduce your IFI in the following years. However, you may report part of your donation (up to €66,667) for an IFI tax credit and the remainder of your donation can be reported for an income tax credit, with a maximum credit of 20% of your taxable income.
