In California, a 501(c)(3) tax-exempt status refers to both the federal recognition from the IRS and a separate state exemption from the California Franchise Tax Board (FTB). An organization must obtain both to be fully exempt from federal and state income taxes.
A California nonprofit corporation is not automatically exempt from state taxes, even with a federal 501(c)(3) determination.
Nonprofits that have both federal and state income tax exemption can also apply for property tax relief.
California does not provide a broad sales and use tax exemption for nonprofits, including 501(c)(3)s.
