The club of 100

Silver Friends
A Silver Friend supports the work of the Mensa Foundation with a one-off contribution of € 1,000. The Mensa Foundation continues to be in contact with the Silver Friends, for example through special invitations to the presentation of the Awards and the annual benefit auction in January (suspended under COVID-19). In addition, there is the annual dinner with the chair where the Founding and Silver Friends to join and to discuss the course of the foundation.

Your own idea of fundraising
Naturally, the Mensa Foundation welcomes Foundation-raising campaigns and other creative ways people come up with to support our goals financially. For example, Esmeralda Klein Reesink organized a Fundraising campaign for her PhD and a group of volunteers organized a great benefit dinner on several occasions. The starting point is that the organizer himself devises the activity and is responsible for the event. The Mensa Foundation thinks along with you and supports you with Communications if necessary.

Include the Mensa Foundation in your will
You can have it included in your will, that in the event of your death, all or part of your estate will go to the Mensa Foundation. This is called a bequest. A bequest must be included in a will and is directly in favor of the Mensa Foundation. As a public benefit institution (ANBI) and a not-for-profit organization, the Mensa Foundation does not have to pay inheritance tax on legacies. If you are considering this, be well informed in advance by a public notary who draws up your will. The tax authorities also provide information about inheritance law, inheritance tax and exemptions. And contact and we will help you with the required procedure.
