The California Secretary of State has posted copies of the income tax returns of all sixty-one gubernatorial candidates on her webpage. See the link here. Write-in candidates need not disclose their income tax returns, and in any event the deadline for write-in candidates to file is not until May.

Eight candidates filed an affidavit that they did not file income tax returns in any of the last five years.

No other state requires candidates for any elective office to have their tax returns made publicly available. In California, governor is the only such office. The law for presidential candidates was declared unconstitutional in both federal and state courts in 2019.
