Taxation and Finance California 4 Minutes Read · published February 20, 2026 Flag of California

Ontario, California homeowners who are seniors or qualifying veterans may be eligible for state-administered property tax exemptions or deferrals administered locally by the San Bernardino County Assessor and Treasurer-Tax Collector. This guide explains the typical programs available in Ontario, how to confirm eligibility, where to find official forms, and the enforcement and appeal pathways you need to know when applying or disputing a decision. For specific eligibility rules, filing deadlines, and application forms, contact the County Assessor or view the county resource linked below.[1]

Common Exemptions and Deferral Programs

Municipal ordinances do not set property tax exemptions in California; exemptions and deferrals for seniors and disabled veterans are created by state law and administered by the county assessor. Typical programs that affect Ontario property owners include:

  • Homeowners' exemption: reduces assessed value for a primary residence when claimed.
  • Disabled veterans' exemption: state-authorized exemptions or exclusions for qualifying veterans or their surviving spouses.
  • Property tax postponement/deferral programs: allow eligible seniors or disabled homeowners to defer payment of property taxes under state-authorized programs administered locally.
Eligibility and amounts are set by state law and applied locally by the county assessor.

Penalties & Enforcement

Because exemptions are administered by San Bernardino County, the County Assessor and the Treasurer-Tax Collector are the primary offices that review claims, remove improperly claimed exemptions, and collect any resulting taxes, penalties, or interest.
