In the case of one-off support, your gift can be allocated to the Institute’s operational budget. This budget funds all the Institute’s work: scientific events, hosting invited researchers and support functions. If you have chosen to support a specific activity such as a conference, IHES allocates your gift to the project for the duration you have set.
Each year, those gifts represent around 6% of the Institute’s annual budget.

A gift to the Institute’s endowment funds makes your support permanent, as only the interest generated from the endowment is used, in perpetuity. When you contribute to the Institute’s endowment, you can support the general endowment fund or a specific activity within it.
Thanks to your generosity, the Institute’s endowment currently funds around 18% of its operations.

Tax benefits

Each donation to IHES helps to advance research and attracts a range of tax benefits for donors, depending on the country of their residence.

ihes-soutien-franceIn France

The Institut des Hautes Etudes Scientifiques is a foundation officially recognized as being in the public interest according to French law. Any donation made by a French tax resident to IHES provides tax benefits to the donor:

For individuals
Income tax: 66% of donations made by individuals to the Institut des Hautes Études Scientifiques are tax deductible, provided they do not exceed 20% of the donor’s taxable income.
If gifts exceed the 20% income limit, the donor may defer the tax deduction on the excess amount over the next five years.
“Impôt de solidarité sur la fortune”: 75% of the gifts made to certain not-for-profit organizations such as IHES, up to a limit of 50 000€, are tax deductible for donors who pay this tax.

For companies
Payments made by companies to the Institut des Hautes Études Scientifiques result in a reduction in their corporate or income tax of 60% of the gift value. The limit beyond which it is no longer tax deductible is 0.5% of the company’s turnover.
If the payments exceed 0.5% of turnover, or if the company is in deficit, it may defer tax deductibility over five years.
