Reducing your ISF

Give your solidarity tax to a worthy cause – turn it into a catalyst for medical progress.


As a research organization and a foundation with recognized charitable status, the Institut Pasteur is doubly authorized to receive donations under the 2007 fiscal package (the loi TEPA), which allows individuals subject to the solidarity tax on wealth (ISF) to deduct up to 75% of their donations from this tax, up to a maximum of €50,000.

This particularly beneficial tax mechanism means that if you are subject to the ISF, you can use your tax payment to support the biomedial research carried out by the Institut Pasteur's teams. Why not use your tax to help fight disease?

How it works

Only taxpayers for whom the net taxable value of their assets was higher than €1,300,000 on January 1, 2016 are liable for the ISF. The official dates for the declaration and payment of your tax vary according to your assets.
