Taxation: private detention facilities

California will impose a 25% annual tax on private detention facility operators’ California-attributable gross income starting July 1, 2028.

The tax applies whether a facility contracts with a federal, state, or local agency. Net revenue, subject to legislative appropriation, will support immigration-related services.

  • Directs the California Department of Tax and Fee Administration to collect and enforce the tax, including through regulations, refunds, and appeals.
  • Deposits revenue after refunds and administrative reimbursement into the Due Process for All Fund for immigration-related services, when appropriated by the Legislature.

Who it affects ​

  • Private detention facility operators, including those contracting with federal, state, or local agencies.
  • The California Department of Tax and Fee Administration.
  • Recipients of immigration-related services funded through legislative appropriations.
