2023 Real Estate Tax Assessment Appeal Deadlines in California

California property owners have limited time to review their assessments and determine whether challenging their values might lead to assessment reductions.

Background on California Propositions

California’s Proposition 13 requires county assessors to reassess real property due to a change in ownership, newly completed construction, or property renovation.

California’s Proposition 8 allows taxpayers to appeal overstated county assessed values which have declined due to market conditions. Many property classifications, such as office buildings, hotels, and retail, have seen dramatic declines in value in recent years.

Professionals also routinely engage with local county agencies and are accustomed to the county’s appeals process and administrative procedures.
