Any Californian can become a sustaining supporter of the Independent California Institute by making a tax-deductible donation of as little as $5 a month.

Three reasons to become a sustaining supporter of the Institute:

  • Support ground-breaking research
  • Educate Californians on our relationship with the federal government
  • Change the conversation around California Independence

Donations to the Independent California Institute (EIN 83-1377726) are fully tax-deductible.
