Disaster loss deduction

You may deduct any President or Governor declared loss caused by a disaster you suffered in California. California law generally follows federal law regarding the treatment of losses incurred as a result of a casualty or a disaster.

Types of losses that may qualify

Casualty loss

You were not repaid for the damage to your property that was lost or damaged due to a sudden, unexpected, or unusual:

  • Earthquake
  • Fire
  • Flood
  • Similar event

You may deduct a disaster loss suffered in California beginning on or after January 1, 2014, and before January 1, 2029. For 2014 and prior, see How to Claim a State Tax Deduction for Your Disaster Loss (FTB Pub 1034).

How to claim the disaster loss deduction on your tax return

The disaster loss must be claimed in the taxable year the disaster occurred or in the taxable year immediately before the disaster occurred. If you meet the qualifications to claim a disaster loss, the same disaster rules and extended deadlines apply to you.
